By contrast, -the GNU General Public License is intended to guarantee your freedom to -share and change all versions of a program--to make sure it remains free -software for all its users. We, the Free Software Foundation, use the -GNU General Public License for most of our software; it applies also to -any other work released this way by its authors. You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -them if you wish), that you receive source code or can get it if you -want it, that you can change the software or use pieces of it in new -free programs, and that you know you can do these things. - - To protect your rights, we need to prevent others from denying you -these rights or asking you to surrender the rights. Therefore, you have -certain responsibilities if you distribute copies of the software, or if -you modify it: responsibilities to respect the freedom of others. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must pass on to the recipients the same -freedoms that you received. You must make sure that they, too, receive -or can get the source code. And you must show them these terms so they -know their rights. - - Developers that use the GNU GPL protect your rights with two steps: -(1) assert copyright on the software, and (2) offer you this License -giving you legal permission to copy, distribute and/or modify it. - - For the developers' and authors' protection, the GPL clearly explains -that there is no warranty for this free software. For both users' and -authors' sake, the GPL requires that modified versions be marked as -changed, so that their problems will not be attributed erroneously to -authors of previous versions. - - Some devices are designed to deny users access to install or run -modified versions of the software inside them, although the manufacturer -can do so. This is fundamentally incompatible with the aim of -protecting users' freedom to change the software. The systematic -pattern of such abuse occurs in the area of products for individuals to -use, which is precisely where it is most unacceptable. Therefore, we -have designed this version of the GPL to prohibit the practice for those -products. If such problems arise substantially in other domains, we -stand ready to extend this provision to those domains in future versions -of the GPL, as needed to protect the freedom of users. - - Finally, every program is threatened constantly by software patents. -States should not allow patents to restrict development and use of -software on general-purpose computers, but in those that do, we wish to -avoid the special danger that patents applied to a free program could -make it effectively proprietary. To prevent this, the GPL assures that -patents cannot be used to render the program non-free. - - The precise terms and conditions for copying, distribution and -modification follow. - - TERMS AND CONDITIONS - - 0. Definitions. - - "This License" refers to version 3 of the GNU General Public License. - - "Copyright" also means copyright-like laws that apply to other kinds of -works, such as semiconductor masks. - - "The Program" refers to any copyrightable work licensed under this -License. Each licensee is addressed as "you". "Licensees" and -"recipients" may be individuals or organizations. - - To "modify" a work means to copy from or adapt all or part of the work -in a fashion requiring copyright permission, other than the making of an -exact copy. The resulting work is called a "modified version" of the -earlier work or a work "based on" the earlier work. - - A "covered work" means either the unmodified Program or a work based -on the Program. - - To "propagate" a work means to do anything with it that, without -permission, would make you directly or secondarily liable for -infringement under applicable copyright law, except executing it on a -computer or modifying a private copy. Propagation includes copying, -distribution (with or without modification), making available to the -public, and in some countries other activities as well. - - To "convey" a work means any kind of propagation that enables other -parties to make or receive copies. Mere interaction with a user through -a computer network, with no transfer of a copy, is not conveying. - - An interactive user interface displays "Appropriate Legal Notices" -to the extent that it includes a convenient and prominently visible -feature that (1) displays an appropriate copyright notice, and (2) -tells the user that there is no warranty for the work (except to the -extent that warranties are provided), that licensees may convey the -work under this License, and how to view a copy of this License. If -the interface presents a list of user commands or options, such as a -menu, a prominent item in the list meets this criterion. - - 1. Source Code. - - The "source code" for a work means the preferred form of the work -for making modifications to it. "Object code" means any non-source -form of a work. - - A "Standard Interface" means an interface that either is an official -standard defined by a recognized standards body, or, in the case of -interfaces specified for a particular programming language, one that -is widely used among developers working in that language. - - The "System Libraries" of an executable work include anything, other -than the work as a whole, that (a) is included in the normal form of -packaging a Major Component, but which is not part of that Major -Component, and (b) serves only to enable use of the work with that -Major Component, or to implement a Standard Interface for which an -implementation is available to the public in source code form. A -"Major Component", in this context, means a major essential component -(kernel, window system, and so on) of the specific operating system -(if any) on which the executable work runs, or a compiler used to -produce the work, or an object code interpreter used to run it. - - The "Corresponding Source" for a work in object code form means all -the source code needed to generate, install, and (for an executable -work) run the object code and to modify the work, including scripts to -control those activities. However, it does not include the work's -System Libraries, or general-purpose tools or generally available free -programs which are used unmodified in performing those activities but -which are not part of the work. For example, Corresponding Source -includes interface definition files associated with source files for -the work, and the source code for shared libraries and dynamically -linked subprograms that the work is specifically designed to require, -such as by intimate data communication or control flow between those -subprograms and other parts of the work. - - The Corresponding Source need not include anything that users -can regenerate automatically from other parts of the Corresponding -Source. - - The Corresponding Source for a work in source code form is that -same work. - - 2. Basic Permissions. - - All rights granted under this License are granted for the term of -copyright on the Program, and are irrevocable provided the stated -conditions are met. This License explicitly affirms your unlimited -permission to run the unmodified Program. The output from running a -covered work is covered by this License only if the output, given its -content, constitutes a covered work. This License acknowledges your -rights of fair use or other equivalent, as provided by copyright law. - - You may make, run and propagate covered works that you do not -convey, without conditions so long as your license otherwise remains -in force. You may convey covered works to others for the sole purpose -of having them make modifications exclusively for you, or provide you -with facilities for running those works, provided that you comply with -the terms of this License in conveying all material for which you do -not control copyright. Those thus making or running the covered works -for you must do so exclusively on your behalf, under your direction -and control, on terms that prohibit them from making any copies of -your copyrighted material outside their relationship with you. - - Conveying under any other circumstances is permitted solely under -the conditions stated below. Sublicensing is not allowed; section 10 -makes it unnecessary. - - 3. Protecting Users' Legal Rights From Anti-Circumvention Law. - - No covered work shall be deemed part of an effective technological -measure under any applicable law fulfilling obligations under article -11 of the WIPO copyright treaty adopted on 20 December 1996, or -similar laws prohibiting or restricting circumvention of such -measures. - - When you convey a covered work, you waive any legal power to forbid -circumvention of technological measures to the extent such circumvention -is effected by exercising rights under this License with respect to -the covered work, and you disclaim any intention to limit operation or -modification of the work as a means of enforcing, against the work's -users, your or third parties' legal rights to forbid circumvention of -technological measures. - - 4. Conveying Verbatim Copies. - - You may convey verbatim copies of the Program's source code as you -receive it, in any medium, provided that you conspicuously and -appropriately publish on each copy an appropriate copyright notice; -keep intact all notices stating that this License and any -non-permissive terms added in accord with section 7 apply to the code; -keep intact all notices of the absence of any warranty; and give all -recipients a copy of this License along with the Program. - - You may charge any price or no price for each copy that you convey, -and you may offer support or warranty protection for a fee. - - 5. Conveying Modified Source Versions. - - You may convey a work based on the Program, or the modifications to -produce it from the Program, in the form of source code under the -terms of section 4, provided that you also meet all of these conditions: - - a) The work must carry prominent notices stating that you modified - it, and giving a relevant date. - - b) The work must carry prominent notices stating that it is - released under this License and any conditions added under section - 7. This requirement modifies the requirement in section 4 to - "keep intact all notices". - - c) You must license the entire work, as a whole, under this - License to anyone who comes into possession of a copy. This - License will therefore apply, along with any applicable section 7 - additional terms, to the whole of the work, and all its parts, - regardless of how they are packaged. This License gives no - permission to license the work in any other way, but it does not - invalidate such permission if you have separately received it. - - d) If the work has interactive user interfaces, each must display - Appropriate Legal Notices; however, if the Program has interactive - interfaces that do not display Appropriate Legal Notices, your - work need not make them do so. - - A compilation of a covered work with other separate and independent -works, which are not by their nature extensions of the covered work, -and which are not combined with it such as to form a larger program, -in or on a volume of a storage or distribution medium, is called an -"aggregate" if the compilation and its resulting copyright are not -used to limit the access or legal rights of the compilation's users -beyond what the individual works permit. Inclusion of a covered work -in an aggregate does not cause this License to apply to the other -parts of the aggregate. - - 6. Conveying Non-Source Forms. - - You may convey a covered work in object code form under the terms -of sections 4 and 5, provided that you also convey the -machine-readable Corresponding Source under the terms of this License, -in one of these ways: - - a) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by the - Corresponding Source fixed on a durable physical medium - customarily used for software interchange. - - b) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by a - written offer, valid for at least three years and valid for as - long as you offer spare parts or customer support for that product - model, to give anyone who possesses the object code either (1) a - copy of the Corresponding Source for all the software in the - product that is covered by this License, on a durable physical - medium customarily used for software interchange, for a price no - more than your reasonable cost of physically performing this - conveying of source, or (2) access to copy the - Corresponding Source from a network server at no charge. - - c) Convey individual copies of the object code with a copy of the - written offer to provide the Corresponding Source. This - alternative is allowed only occasionally and noncommercially, and - only if you received the object code with such an offer, in accord - with subsection 6b. - - d) Convey the object code by offering access from a designated - place (gratis or for a charge), and offer equivalent access to the - Corresponding Source in the same way through the same place at no - further charge. You need not require recipients to copy the - Corresponding Source along with the object code. If the place to - copy the object code is a network server, the Corresponding Source - may be on a different server (operated by you or a third party) - that supports equivalent copying facilities, provided you maintain - clear directions next to the object code saying where to find the - Corresponding Source. Regardless of what server hosts the - Corresponding Source, you remain obligated to ensure that it is - available for as long as needed to satisfy these requirements. - - e) Convey the object code using peer-to-peer transmission, provided - you inform other peers where the object code and Corresponding - Source of the work are being offered to the general public at no - charge under subsection 6d. - - A separable portion of the object code, whose source code is excluded -from the Corresponding Source as a System Library, need not be -included in conveying the object code work. - - A "User Product" is either (1) a "consumer product", which means any -tangible personal property which is normally used for personal, family, -or household purposes, or (2) anything designed or sold for incorporation -into a dwelling. In determining whether a product is a consumer product, -doubtful cases shall be resolved in favor of coverage. For a particular -product received by a particular user, "normally used" refers to a -typical or common use of that class of product, regardless of the status -of the particular user or of the way in which the particular user -actually uses, or expects or is expected to use, the product. A product -is a consumer product regardless of whether the product has substantial -commercial, industrial or non-consumer uses, unless such uses represent -the only significant mode of use of the product. - - "Installation Information" for a User Product means any methods, -procedures, authorization keys, or other information required to install -and execute modified versions of a covered work in that User Product from -a modified version of its Corresponding Source. The information must -suffice to ensure that the continued functioning of the modified object -code is in no case prevented or interfered with solely because -modification has been made. - - If you convey an object code work under this section in, or with, or -specifically for use in, a User Product, and the conveying occurs as -part of a transaction in which the right of possession and use of the -User Product is transferred to the recipient in perpetuity or for a -fixed term (regardless of how the transaction is characterized), the -Corresponding Source conveyed under this section must be accompanied -by the Installation Information. But this requirement does not apply -if neither you nor any third party retains the ability to install -modified object code on the User Product (for example, the work has -been installed in ROM). - - The requirement to provide Installation Information does not include a -requirement to continue to provide support service, warranty, or updates -for a work that has been modified or installed by the recipient, or for -the User Product in which it has been modified or installed. Access to a -network may be denied when the modification itself materially and -adversely affects the operation of the network or violates the rules and -protocols for communication across the network. - - Corresponding Source conveyed, and Installation Information provided, -in accord with this section must be in a format that is publicly -documented (and with an implementation available to the public in -source code form), and must require no special password or key for -unpacking, reading or copying. - - 7. Additional Terms. - - "Additional permissions" are terms that supplement the terms of this -License by making exceptions from one or more of its conditions. -Additional permissions that are applicable to the entire Program shall -be treated as though they were included in this License, to the extent -that they are valid under applicable law. If additional permissions -apply only to part of the Program, that part may be used separately -under those permissions, but the entire Program remains governed by -this License without regard to the additional permissions. - - When you convey a copy of a covered work, you may at your option -remove any additional permissions from that copy, or from any part of -it. (Additional permissions may be written to require their own -removal in certain cases when you modify the work.) You may place -additional permissions on material, added by you to a covered work, -for which you have or can give appropriate copyright permission. - - Notwithstanding any other provision of this License, for material you -add to a covered work, you may (if authorized by the copyright holders of -that material) supplement the terms of this License with terms: - - a) Disclaiming warranty or limiting liability differently from the - terms of sections 15 and 16 of this License; or - - b) Requiring preservation of specified reasonable legal notices or - author attributions in that material or in the Appropriate Legal - Notices displayed by works containing it; or - - c) Prohibiting misrepresentation of the origin of that material, or - requiring that modified versions of such material be marked in - reasonable ways as different from the original version; or - - d) Limiting the use for publicity purposes of names of licensors or - authors of the material; or - - e) Declining to grant rights under trademark law for use of some - trade names, trademarks, or service marks; or - - f) Requiring indemnification of licensors and authors of that - material by anyone who conveys the material (or modified versions of - it) with contractual assumptions of liability to the recipient, for - any liability that these contractual assumptions directly impose on - those licensors and authors. - - All other non-permissive additional terms are considered "further -restrictions" within the meaning of section 10. If the Program as you -received it, or any part of it, contains a notice stating that it is -governed by this License along with a term that is a further -restriction, you may remove that term. If a license document contains -a further restriction but permits relicensing or conveying under this -License, you may add to a covered work material governed by the terms -of that license document, provided that the further restriction does -not survive such relicensing or conveying. - - If you add terms to a covered work in accord with this section, you -must place, in the relevant source files, a statement of the -additional terms that apply to those files, or a notice indicating -where to find the applicable terms. - - Additional terms, permissive or non-permissive, may be stated in the -form of a separately written license, or stated as exceptions; -the above requirements apply either way. - - 8. Termination. - - You may not propagate or modify a covered work except as expressly -provided under this License. Any attempt otherwise to propagate or -modify it is void, and will automatically terminate your rights under -this License (including any patent licenses granted under the third -paragraph of section 11). - - However, if you cease all violation of this License, then your -license from a particular copyright holder is reinstated (a) -provisionally, unless and until the copyright holder explicitly and -finally terminates your license, and (b) permanently, if the copyright -holder fails to notify you of the violation by some reasonable means -prior to 60 days after the cessation. - - Moreover, your license from a particular copyright holder is -reinstated permanently if the copyright holder notifies you of the -violation by some reasonable means, this is the first time you have -received notice of violation of this License (for any work) from that -copyright holder, and you cure the violation prior to 30 days after -your receipt of the notice. - - Termination of your rights under this section does not terminate the -licenses of parties who have received copies or rights from you under -this License. If your rights have been terminated and not permanently -reinstated, you do not qualify to receive new licenses for the same -material under section 10. - - 9. Acceptance Not Required for Having Copies. - - You are not required to accept this License in order to receive or -run a copy of the Program. Ancillary propagation of a covered work -occurring solely as a consequence of using peer-to-peer transmission -to receive a copy likewise does not require acceptance. However, -nothing other than this License grants you permission to propagate or -modify any covered work. These actions infringe copyright if you do -not accept this License. Therefore, by modifying or propagating a -covered work, you indicate your acceptance of this License to do so. - - 10. Automatic Licensing of Downstream Recipients. - - Each time you convey a covered work, the recipient automatically -receives a license from the original licensors, to run, modify and -propagate that work, subject to this License. You are not responsible -for enforcing compliance by third parties with this License. - - An "entity transaction" is a transaction transferring control of an -organization, or substantially all assets of one, or subdividing an -organization, or merging organizations. If propagation of a covered -work results from an entity transaction, each party to that -transaction who receives a copy of the work also receives whatever -licenses to the work the party's predecessor in interest had or could -give under the previous paragraph, plus a right to possession of the -Corresponding Source of the work from the predecessor in interest, if -the predecessor has it or can get it with reasonable efforts. - - You may not impose any further restrictions on the exercise of the -rights granted or affirmed under this License. For example, you may -not impose a license fee, royalty, or other charge for exercise of -rights granted under this License, and you may not initiate litigation -(including a cross-claim or counterclaim in a lawsuit) alleging that -any patent claim is infringed by making, using, selling, offering for -sale, or importing the Program or any portion of it. - - 11. Patents. - - A "contributor" is a copyright holder who authorizes use under this -License of the Program or a work on which the Program is based. The -work thus licensed is called the contributor's "contributor version". - - A contributor's "essential patent claims" are all patent claims -owned or controlled by the contributor, whether already acquired or -hereafter acquired, that would be infringed by some manner, permitted -by this License, of making, using, or selling its contributor version, -but do not include claims that would be infringed only as a -consequence of further modification of the contributor version. For -purposes of this definition, "control" includes the right to grant -patent sublicenses in a manner consistent with the requirements of -this License. - - Each contributor grants you a non-exclusive, worldwide, royalty-free -patent license under the contributor's essential patent claims, to -make, use, sell, offer for sale, import and otherwise run, modify and -propagate the contents of its contributor version. - - In the following three paragraphs, a "patent license" is any express -agreement or commitment, however denominated, not to enforce a patent -(such as an express permission to practice a patent or covenant not to -sue for patent infringement). To "grant" such a patent license to a -party means to make such an agreement or commitment not to enforce a -patent against the party. - - If you convey a covered work, knowingly relying on a patent license, -and the Corresponding Source of the work is not available for anyone -to copy, free of charge and under the terms of this License, through a -publicly available network server or other readily accessible means, -then you must either (1) cause the Corresponding Source to be so -available, or (2) arrange to deprive yourself of the benefit of the -patent license for this particular work, or (3) arrange, in a manner -consistent with the requirements of this License, to extend the patent -license to downstream recipients. "Knowingly relying" means you have -actual knowledge that, but for the patent license, your conveying the -covered work in a country, or your recipient's use of the covered work -in a country, would infringe one or more identifiable patents in that -country that you have reason to believe are valid. - - If, pursuant to or in connection with a single transaction or -arrangement, you convey, or propagate by procuring conveyance of, a -covered work, and grant a patent license to some of the parties -receiving the covered work authorizing them to use, propagate, modify -or convey a specific copy of the covered work, then the patent license -you grant is automatically extended to all recipients of the covered -work and works based on it. - - A patent license is "discriminatory" if it does not include within -the scope of its coverage, prohibits the exercise of, or is -conditioned on the non-exercise of one or more of the rights that are -specifically granted under this License. You may not convey a covered -work if you are a party to an arrangement with a third party that is -in the business of distributing software, under which you make payment -to the third party based on the extent of your activity of conveying -the work, and under which the third party grants, to any of the -parties who would receive the covered work from you, a discriminatory -patent license (a) in connection with copies of the covered work -conveyed by you (or copies made from those copies), or (b) primarily -for and in connection with specific products or compilations that -contain the covered work, unless you entered into that arrangement, -or that patent license was granted, prior to 28 March 2007. - - Nothing in this License shall be construed as excluding or limiting -any implied license or other defenses to infringement that may -otherwise be available to you under applicable patent law. - - 12. No Surrender of Others' Freedom. - - If conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot convey a -covered work so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you may -not convey it at all. For example, if you agree to terms that obligate you -to collect a royalty for further conveying from those to whom you convey -the Program, the only way you could satisfy both those terms and this -License would be to refrain entirely from conveying the Program. - - 13. Use with the GNU Affero General Public License. - - Notwithstanding any other provision of this License, you have -permission to link or combine any covered work with a work licensed -under version 3 of the GNU Affero General Public License into a single -combined work, and to convey the resulting work. The terms of this -License will continue to apply to the part which is the covered work, -but the special requirements of the GNU Affero General Public License, -section 13, concerning interaction through a network will apply to the -combination as such. - - 14. Revised Versions of this License. - - The Free Software Foundation may publish revised and/or new versions of -the GNU General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - - Each version is given a distinguishing version number. If the -Program specifies that a certain numbered version of the GNU General -Public License "or any later version" applies to it, you have the -option of following the terms and conditions either of that numbered -version or of any later version published by the Free Software -Foundation. If the Program does not specify a version number of the -GNU General Public License, you may choose any version ever published -by the Free Software Foundation. - - If the Program specifies that a proxy can decide which future -versions of the GNU General Public License can be used, that proxy's -public statement of acceptance of a version permanently authorizes you -to choose that version for the Program. - - Later license versions may give you additional or different -permissions. However, no additional obligations are imposed on any -author or copyright holder as a result of your choosing to follow a -later version. - - 15. Disclaimer of Warranty. - - THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY -APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT -HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY -OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, -THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM -IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF -ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. Limitation of Liability. - - IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS -THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY -GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE -USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF -DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD -PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), -EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF -SUCH DAMAGES. - - 17. Interpretation of Sections 15 and 16. - - If the disclaimer of warranty and limitation of liability provided -above cannot be given local legal effect according to their terms, -reviewing courts shall apply local law that most closely approximates -an absolute waiver of all civil liability in connection with the -Program, unless a warranty or assumption of liability accompanies a -copy of the Program in return for a fee. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -state the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software: you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation, either version 3 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License - along with this program. If not, see . - -Also add information on how to contact you by electronic and paper mail. - - If the program does terminal interaction, make it output a short -notice like this when it starts in an interactive mode: - - Copyright (C) - This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License. Of course, your program's commands -might be different; for a GUI interface, you would use an "about box". - - You should also get your employer (if you work as a programmer) or school, -if any, to sign a "copyright disclaimer" for the program, if necessary. -For more information on this, and how to apply and follow the GNU GPL, see -. - - The GNU General Public License does not permit incorporating your program -into proprietary programs. If your program is a subroutine library, you -may consider it more useful to permit linking proprietary applications with -the library. If this is what you want to do, use the GNU Lesser General -Public License instead of this License.

Do "make all doc". - - 2. On the computer to run as a Mandos client, run the following - command: - For Debian: su - -c 'make install-client' - For Ubuntu: sudo make install-client - - This will also create an OpenPGP key, which will take some time - and entropy, so be patient. - - 3. Run the following command: - For Debian: su - -c 'mandos-keygen --password' - For Ubuntu: sudo mandos-keygen --password - - When prompted, enter the password/passphrase for the encrypted - root file system on this client computer. The command will - output a section of text, starting with a [section header]. Copy - and append this to the file "/etc/mandos/clients.conf" *on the - server computer*. - - 4. Configure the client to use any special configuration needed for - your local system. Note: This is not necessary if the server is - present on the same wired local network as the client. If you do - make changes to /etc/mandos/plugin-runner.conf, the initrd.img - file must be updated, possibly using the following command: - - # update-initramfs -k all -u - - 5. On the server computer, start the server by running the command - For Debian: su - -c 'invoke-rc.d mandos start' - For Ubuntu: sudo service mandos start - - At this point, it is possible to verify that the correct password - will be received by the client by running the command: - - # /usr/lib/mandos/plugins.d/mandos-client \ - --pubkey=/etc/keys/mandos/pubkey.txt \ - --seckey=/etc/keys/mandos/seckey.txt \ - --tls-privkey=/etc/keys/mandos/tls-privkey.pem \ - --tls-pubkey=/etc/keys/mandos/tls-pubkey.pem; echo - - This command should retrieve the password from the server, - decrypt it, and output it to standard output. - - After this, the client computer should be able to reboot without - needing a password entered on the console, as long as it does not - take more than five minutes to reboot. - -* Further customizations - - You may want to tighten or loosen the timeouts in the server - configuration files; see mandos.conf(5) and mandos-clients.conf(5). - If IPsec is not used and SSH is not installed, it is suggested that - a more cryptographically secure checker program is used and -

passfiles with names starting with "-". -** Document known limitation of mandos-keygen --password; it strips - white space from start and end of the password. -* Server -** Bug fix: The server used to fail to restart if the "port" setting - was used. This has been fixed. -** Minor bug fix: Reap zombies left over from checker runs. (Debian - bug #933387) - -Version 1.8.4 (2019-04-09) -* Client -** Fix minor memory leak in plugin-runner. -* Server -** mandos-ctl now has a --debug option to show D-Bus calls. - -Version 1.8.3 (2019-02-11) -* No user-visible changes. - -Version 1.8.2 (2019-02-10) -* Client -** In mandos-keygen, ignore failures to remove files in some cases. - -Version 1.8.1 (2019-02-10) -* Client -** Only generate TLS keys using GnuTLS' certtool, of sufficient - version. Key generation of TLS keys will not happen until a - version of GnuTLS is installed with support for raw public keys. -** Remove any bad keys created by 1.8.0 and openssl. -* Server -** On installation, edit clients.conf and remove the same bad key ID - which was erroneously reported by all 1.8.0 clients. Also do not - trust this key ID in the server. - -Version 1.8.0 (2019-02-10) -* Client -** Use new TLS keys for server communication and identification. - With GnuTLS 3.6 or later, OpenPGP keys are no longer supported. - The client can now use the new "raw public keys" (RFC 7250) API - instead, using GnuTLS 3.6.6. Please note: This *requires* new key - IDs to be added to server's client.conf file. -** New --tls-privkey and --tls-pubkey options to load TLS key files. - If GnuTLS is too old, these options do nothing. -* Server -** Supports either old or new GnuTLS. - The server now supports using GnuTLS 3.6.6 and clients connecting - with "raw public keys" as identification. The server will read - both fingerprints and key IDs from clients.conf file, and will use - either one or the other, depending on what is supported by GnuTLS - on the system. Please note: both are *not* supported at once; if - one type is supported by GnuTLS, all values of the other type from - clients.conf are ignored. - -Version 1.7.20 (2018-08-19) -* Client -** Fix: Adapt to the Debian cryptsetup package 2.0.3 or later. - Important: in that version or later, the plugins "askpass-fifo", - "password-prompt", and "plymouth" will no longer be run, since they - would conflict with what cryptsetup is doing.

See the DBUS-API - file for the currently recommended API. Note: the original API - still works, but is deprecated. -* Client -** Can now find Mandos server even if the server has an IPv6 address - on a network without IPv6 Router Advertisment (like if the Mandos - client itself is the router, or there is an IPv6 router advertising - a network other than the one which the Mandos server is on.) -** Use a better value than 1024 for the default number of DH bits. - This better value is either provided by a DH parameters file (see - below) or an appropriate number of DH bits is determined based on - the PGP key. -** Bug fix: mandos-keygen now generates correct output for the - "Checker" variable even if the SSH server on the Mandos client has - multiple SSH key types. -** Can now use pre-generated Diffie-Hellman parameters from a file. - -Version 1.6.9 (2014-10-05) -* Server -** Changed to emit standard D-Bus signal when D-Bus properties change. - (The old signal is still emitted too, but marked as deprecated.) - -Version 1.6.8 (2014-08-06) -* Client -** Bug fix: mandos-keygen now generates working SSH checker commands. -* Server -** Bug fix: "mandos-monitor" now really redraws screen on Ctrl-L. -** Now requires Python 2.7. - -Version 1.6.7 (2014-07-17) -* Client -** Bug fix: Now compatible with GPGME 1.5.0. -** Bug fix: Fixed minor memory leaks. -* Server -** "mandos-monitor" now has verbose logging, toggleable with "v". - -Version 1.6.6 (2014-07-13) -* Client -** If client host has an SSH server, "mandos-keygen --password" now - outputs "checker" option which uses "ssh-keyscan"; this is more - secure than the default "fping" checker. -** Bug fix: allow "." in network hook names, to match documentation. -** Better error messages. -* Server -** New --no-zeroconf option. -** Bug fix: Fix --servicename option, broken since 1.6.4. -** Bug fix: Fix --socket option work for --socket=0. - -Version 1.6.5 (2014-05-11) -* Client -** Work around bug in GnuPG -** Give better error messages when run without sufficient privileges -** Only warn if workaround for Debian bug #633582 was necessary and - failed, not if it failed and was unnecessary. - -Version 1.6.4 (2014-02-16) -* Server -** Very minor fix to self-test code. - -Version 1.6.3 (2014-01-21) -* Server -** Add systemd support. -** For PID file, fall back to /var/run if /run does not exist. -* Client -** Moved files from /usr/lib/mandos to whatever the architecture - specifies, like /usr/lib/x86_64-linux-gnu/mandos or - /usr/lib64/mandos. - -Version 1.6.2 (2013-10-24) -* Server -** PID file moved from /var/run to /run. -** Bug fix: Handle long secrets when saving client state. -** Bug fix: Use more magic in the GnuTLS priority string to handle - both old DSA/ELG 2048-bit keys and new RSA/RSA 4096-bit keys. -* Client -** mandos-keygen: Bug fix: now generate RSA keys which GnuTLS can use. - Bug fix: Output passphrase prompts even when - redirecting standard output. - -Version 1.6.1 (2013-10-13) -* Server -** All client options for time intervals now also take an RFC 3339 - duration. The same for all options to mandos-ctl. -** Bug fix: Handle fast checkers (like ":") correctly. -** Bug fix: Don't print output from checkers when running in - foreground. -** Bug fix: Do not fail when client is removed from clients.conf but - saved settings remain. -** Bug fix: mandos-monitor now displays standout (reverse video) again - using new version of Urwid. -** Bug fix: Make boolean options work from the config file again. -** Bug fix: Make --no-ipv6 work again. -** New default priority string to be slightly more compatible with - older versions of GnuTLS. -* Client -** Bug fix: Fix bashism in mandos-keygen. -** Default key and subkey types are now RSA and RSA, respectively. - Also, new default key size is 4096 bits. - -Version 1.6.0 (2012-06-18) -* Server -** Takes new --foreground option -** Init script supports new "status" action. -* Client -** Now uses all interfaces by default; the --interface option can - still be used to restrict it, and the argument to --interface (as - well as the $DEVICE environment variable for the network hooks) is - now a comma-separated list of interfaces to use. - -Version 1.5.5 (2012-06-01) -* Server -** Server takes new --socket option - -Version 1.5.4 (2012-05-20) -* Server -** Bug fix: Regression fix: Make non-zero approval timeout values work. -** Bug fix: Regression fix: Allow changing the Timeout D-Bus property. -** Fall back to not bind to an interface if an invalid interface name - is given. -** Removed support for undocumented feature of using plain "%%s" in - "checker" client option. -** Old D-Bus interface are now marked as deprecated. -** mandos-monitor: Bug fix: show approval timers correctly. -** mandos-ctl: Show "Extended Timeout" correctly, not as milliseconds. - -Version 1.5.3 (2012-01-15) -* Server -** Add D-Bus property se.recompile.Client.LastCheckerStatus and use it - in mandos-monitor. -* Client -** Fix bugs in the example "bridge" network hook. - -Version 1.5.2 (2012-01-08) -* Server -** Removed D-Bus signal se.recompile.Mandos.NewRequest() added in - 1.5.0.

The aim of this program is therefore - to acquire and then send a password to some other program which - will use the password to unlock the encrypted root disk. - - - This program is not meant to be invoked directly, but can be in - order to test it. - - - - - PURPOSE - - The purpose of this is to enable remote and unattended - rebooting of client host computer with an - encrypted root file system.

The default is - /run/systemd/ask-password as per the - Password Agents specification. - - - - - - - - - Specify a different helper directory. The default is - /lib/mandos/plugin-helpers, which - will exist in the initial RAM disk - environment. (This will simply be passed to the - MANDOS_CLIENT program via the - MANDOSPLUGINHELPERDIR environment variable. - See - mandos-client8mandos.) - - - - - - - - - Change real user ID to USERID - when running MANDOS_CLIENT. - The default is 65534.

Note: This - must be a number, not a name. - - - - - - MANDOS_CLIENT - - - This specifies the file name for - mandos-client8mandos. If the - option is given, any - following options are passed to the MANDOS_CLIENT program. The default is - /lib/mandos/plugins.d/mandos-client - (which is the correct location for the initial - RAM disk environment) without any - options. - - - - - - - - - - Gives a help message about options and their meanings. - - - - - - - - - Ignore normal operation; instead only run self-tests. - Adding the option may show more - options possible in combination with - . - - - - - - - - - Gives a short usage message. - - - - - - - - - - Prints the program version. - - - - - - - - OVERVIEW - - - This program, &COMMANDNAME;, will run on the client side in the - initial RAM disk environment, and is - responsible for getting a password from the Mandos client - program itself, and to send that password to whatever is - currently asking for a password using the systemd Password Agents mechanism. - - To accomplish this, &COMMANDNAME; runs the - mandos-client program (which is the actual - client program communicating with the Mandos server) or, - alternatively, any executable file specified as - MANDOS_CLIENT, and, as soon as a - password is acquired from the - MANDOS_CLIENT program, sends that - password (as per the Password Agents specification) to all currently - unanswered password questions. - - - This program should be started (normally as a systemd service, - which in turn is normally started by a systemd.path - 5 file) as a reaction to - files named ask.xxxx appearing in the agent directory - /run/systemd/ask-password - (or the directory specified by - ). - - - - - EXIT STATUS - - Exit status of this program is zero if no errors were - encountered, and otherwise not. - - - - - ENVIRONMENT - - This program does not use any environment variables itself, it - only passes on its environment to - MANDOS_CLIENT. Also, the - option will affect the - environment variable MANDOSPLUGINHELPERDIR for - MANDOS_CLIENT. - - - - - FILES - - - - /run/systemd/ask-password - - - The default directory to watch for password questions as - per the Password Agents specification; can be changed - by the option. - - - - - /lib/mandos/plugin-helpers - - - The helper directory as supplied to - MANDOS_CLIENT via the - MANDOSPLUGINHELPERDIR environment - variable; can be changed by the - option. - - - - - - - - - BUGS - - - - - EXAMPLE - - - Normal invocation needs no options: - - - &COMMANDNAME; - - - - - Run an alternative MANDOS_CLIENT - program:: - - - &COMMANDNAME; /usr/local/sbin/alternate - - - - - Use alternative locations for the helper directory and the - Mandos client, and add extra options suitable for running in - the normal file system: - - - - - &COMMANDNAME; --helper-directory=/usr/lib/x86_64-linux-gnu/mandos/plugin-helpers -- /usr/lib/x86_64-linux-gnu/mandos/plugins.d/mandos-client --pubkey=/etc/keys/mandos/pubkey.txt --seckey=/etc/keys/mandos/seckey.txt --tls-pubkey=/etc/keys/mandos/tls-pubkey.pem --tls-privkey=/etc/keys/mandos/tls-privkey.pem - - - - - - Use the default location for - mandos-client - 8mandos, but add many - options to it: - - - - -&COMMANDNAME; -- /lib/mandos/mandos-client --pubkey=/etc/mandos/keys/pubkey.txt --seckey=/etc/mandos/keys/seckey.txt --tls-pubkey=/etc/mandos/keys/tls-pubkey.pem --tls-privkey=/etc/mandos/keys/tls-privkey.pem - - - - - - Only run the self-tests: - - - &COMMANDNAME; --test - - - - - SECURITY - - This program will need to run as the root user in order to read - the agent directory and the ask.xxxx files - there, and will, when starting the Mandos client program, - require the ability to set the real user and - group ids to another user, by default user and group 65534, - which are assumed to be non-privileged.

The clients - are identified by the server using a TLS public key; each client - has one unique to it. The server sends the clients an encrypted - password. The encrypted password is decrypted by the clients - using a separate OpenPGP key, and the password is then used to - unlock the root file system, whereupon the computers can - continue booting normally. - - - - - INTRODUCTION - - - You know how it is. You’ve heard of it happening. The Man - comes and takes away your servers, your friends’ servers, the - servers of everybody in the same hosting facility. The servers - of their neighbors, and their neighbors’ friends. The servers - of people who owe them money. And like - that, they’re gone. And you doubt you’ll - ever see them again. - - - That is why your servers have encrypted root file systems. - However, there’s a downside. There’s no going around it: - rebooting is a pain. Dragging out that rarely-used keyboard and - screen and unraveling cables behind your servers to plug them in - to type in that password is messy, especially if you have many - servers. There are some people who do clever things like using - serial line consoles and daisy-chain it to the next server, and - keep all the servers connected in a ring with serial cables, - which will work, if your servers are physically close enough. - There are also other out-of-band management solutions, but with - all these, you still have to be on hand and - manually type in the password at boot time. Otherwise the - server just sits there, waiting for a password. - - - Wouldn’t it be great if you could have the security of encrypted - root file systems and still have servers that could boot up - automatically if there was a short power outage while you were - asleep? That you could reboot at will, without having someone - run over to the server to type in the password? - - - Well, with Mandos, you (almost) can! The gain in convenience - will only be offset by a small loss in security. The setup is - as follows: - - - The server will still have its encrypted root file system. The - password to this file system will be stored on another computer - (henceforth known as the Mandos server) on the same local - network. The password will not be stored - in plaintext, but encrypted with OpenPGP. To decrypt this - password, a key is needed. This key (the Mandos client key) - will not be stored there, but back on the original server - (henceforth known as the Mandos client) in the initial RAM disk - image. Oh, and all network Mandos client/server communications - will be encrypted, using TLS (SSL). - - - So, at boot time, the Mandos client will ask for its encrypted - data over the network, decrypt the data to get the password, use - the password to decrypt the root file system, and the client can - then continue booting. - - - Now, of course the initial RAM disk image is not on the - encrypted root file system, so anyone who had physical access - could take the Mandos client computer offline and read the disk - with their own tools to get the authentication keys used by a - client. But, by then the Mandos server - should notice that the original server has been offline for too - long, and will no longer give out the encrypted key. The timing - here is the only real weak point, and the method, frequency and - timeout of the server’s checking can be adjusted to any desired - level of paranoia. - - - (The encrypted keys on the Mandos server is on its normal file - system, so those are safe, provided the root file system of - that server is encrypted.) - - - - - FREQUENTLY ASKED QUESTIONS - - Couldn’t the security be defeated by… - - - Grabbing the Mandos client key from the - initrd <emphasis>really quickly</emphasis>? - - This, as mentioned above, is the only real weak point. But if - you set the timing values tight enough, this will be really - difficult to do. An attacker would have to physically - disassemble the client computer, extract the key from the - initial RAM disk image, and then connect to a still - online Mandos server to get the encrypted key, and do - all this before the Mandos server timeout - kicks in and the Mandos server refuses to give out the key to - anyone. - - - Now, as the typical procedure seems to be to barge in and turn - off and grab all computers, to maybe look - at them months later, this is not likely. If someone does that, - the whole system will lock itself up - completely, since Mandos servers are no longer running. - - - For sophisticated attackers who could do - the clever thing, and had physical access - to the server for enough time, it would be simpler to get a key - for an encrypted file system by using hardware memory scanners - and reading it right off the memory bus. - - - - - Replay attacks? - - Nope, the network stuff is all done over TLS, which provides - protection against that. - - - - - Man-in-the-middle? - - No. The server only gives out the passwords to clients which - have in the TLS handshake proven that - they do indeed hold the private key corresponding to that - client. - - - - - How about sniffing the network traffic and decrypting it - later by physically grabbing the Mandos client and using its - key? - - We only use PFS (Perfect Forward Security) - key exchange algorithms in TLS, which protects against this. - - - - - Physically grabbing the Mandos server computer? - - You could protect that computer the - old-fashioned way, with a must-type-in-the-password-at-boot - method. Or you could have two computers be the Mandos server - for each other. - - - Multiple Mandos servers can coexist on a network without any - trouble. They do not clash, and clients will try all - available servers. This means that if just one reboots then - the other can bring it back up, but if both reboot at the same - time they will stay down until someone types in the password - on one of them. - - - - - Faking checker results? - - If the Mandos client does not have an SSH server, the default - is for the Mandos server to use - fping, the replies to which - could be faked to eliminate the timeout. But this could - easily be changed to any shell command, with any security - measures you like. If the Mandos client - has an SSH server, the default - configuration (as generated by - mandos-keygen with the - option) is for the Mandos server - to use an ssh-keyscan command with strict - keychecking, which can not be faked. Alternatively, IPsec - could be used for the ping packets, making them secure. - - - - - - SECURITY - - So, in summary: The only weakness in the Mandos system is from - people who have: - - - - - The power to come in and physically take your servers, - and - - - - - The cunning and patience to do it carefully, one at a time, - and quickly, faking Mandos - client/server responses for each one before the timeout. - - - - - While there are some who may be threatened by people who have - both these attributes, they do not, - probably, constitute the majority. - - - If you do face such opponents, you must - figure that they could just as well open your servers and read - the file system keys right off the memory by running wires to - the memory bus. - - - What Mandos is designed to protect against is - not such determined, focused, and competent - attacks, but against the early morning knock on your door and - the sudden absence of all the servers in your server room. - Which it does nicely. - - - - - PLUGINS - - In the early designs, the - mandos-client8mandos program (which - retrieves a password from the Mandos server) also prompted for a - password on the terminal, in case a Mandos server could not be - found. Other ways of retrieving a password could easily be - envisoned, but this multiplicity of purpose was seen to be too - complex to be a viable way to continue. Instead, the original - program was separated into mandos-client8mandos and password-prompt8mandos, and a plugin-runner8mandos exist to run them both in parallel, allowing - the first successful plugin to provide the password. This - opened up for any number of additional plugins to run, all - competing to be the first to find a password and provide it to - the plugin runner. - - - Four additional plugins are provided: - - - - - plymouth - 8mandos - - - - This prompts for a password when using - plymouth8. - - - - - - usplash - 8mandos - - - - This prompts for a password when using - usplash8. - - - - - - splashy - 8mandos - - - - This prompts for a password when using - splashy8. - - - - - - askpass-fifo - 8mandos - - - - To provide compatibility with the "askpass" program from - cryptsetup, this plugin listens to the same FIFO as - askpass would do. - - - - - - More plugins can easily be written and added by the system - administrator; see the section called "WRITING PLUGINS" in - plugin-runner - 8mandos to learn the - plugin requirements. - - - - - SYSTEMD - - More advanced startup systems like systemd1, - already have their own plugin-like mechanisms for allowing - multiple agents to independently retrieve a password and deliver - it to the subsystem requesting a password to unlock the root - file system. On these systems, it would make no sense to run - plugin-runner8mandos, the plugins of - which would largely duplicate the work of (and conflict with) - the existing systems prompting for passwords. - - - As for systemd1 in particular, it has - its own Password Agents system. Mandos uses this via its - password-agent8mandos program, which - is run instead of plugin-runner8mandos when systemd1 - is used during system startup. - - - - BUGS - - - - - SEE ALSO - - mandos - 8, - mandos.conf - 5, - mandos-clients.conf - 5, - mandos-ctl - 8, - mandos-monitor - 8, - plugin-runner - 8mandos, - password-agent - 8mandos, - mandos-client - 8mandos, - password-prompt - 8mandos, - plymouth - 8mandos, - usplash - 8mandos, - splashy - 8mandos, - askpass-fifo - 8mandos, - mandos-keygen - 8 - - - - - Mandos - - - - The Mandos home page. - - - - - - - - - - - === added file 'key.pem' --- key.pem 1970-01-01 00:00:00 +0000 +++ key.pem 2007-10-20 21:38:25 +0000 @@ -0,0 +1,51 @@ +-----BEGIN RSA PRIVATE KEY----- +MIIJKAIBAAKCAgEAriPn2IkZ+KvmPGXiAJ4vKFcQPhgZ3jaj+WVd1a1g70ge2sJm +SedEiOO+JDQ8mTolCkgaQ2t1bm5FJBxMqyFwQ4vxymtQd74ymLzfiLts5o+UN0li +gxq2QcS+r3bB5cV8przIblS2YBuK6jfzwludWBTscCqrWKmL51IyglTQVHerEoLd +6KhBB2r5AHbnsF5k0OrdKtZOplfDum7gOaI5kmGkwBXkKaNAq3hkLQR0HIZy3S2n +dfezCkFj7Rr7CUUwpV7VYbL11+GQ1FWFQJc0o4K5pogyyfyK4Jw2WQjDgZWG8mP0 +At9FlLlXNFooiE6cW5vj4/FgKW3WCF9MGGTVpCOJKXUlP6q2Cm9Kp3fg6di0tGn4 +vkRwtBI+jKQbZOOxTGdhe0GI+hm4iTu/lqVCVtPbQOa5aGkIybh/DVbRDp5cvYA+ +2uMC3sdLv2oOinJIviy3ydORjd/OaNbxWmDVjgfI3ppjy1H04iNLBmEK/42iLFtl +OhScteahG1Cc7qtKnuou4kI8LWBsNzVNHiZyWvlW6ZvxqDWJBOKLRK+Gpjy7WwMw +aUv1plbRZrKR+gLrhxR0Eqb1Hp23TxjTEB69JrF1yyYr2QJ8Ik6jqcnalD35Z1KN +gSGrkMsEaGl+HOz5TVkvQdiZN/JWOZta4NlpDViG3i8d/VNjACkWMYka3/sCAwEA +AQKCAgEApV0fWvbGnOfQGOa++Ms+CNa0a+LDHctRZxElTDX6aP9ZnW8hZ2igIkXy +V7rrGK6oYd0aY4910koQijv9ajy0uM/56biCj1MkBPrGYrdosIEDxISBcfI5xLaq +RUFG24Tv2/5FbtAu55EAF27OoXASOISWCeXbFLTcT+w0XqNfufZxk4CGbdro9bxV +fGVtmoPoxKNjJryfr0KEcVO8xb4RYborkuS25/tI/Au1RTKHeFcMWJB0B4gSktiJ +pa0LWkBD86Xch4xD/J8MwzX69d0gdW08ErIfWMPitWxiB6ZU0YdGwIK+QsP29UYT +U3mSJ+5OeIfOnrSmFnFg4E5umnOWk1fCkX9FpFwjFy2H9FrF/BHyZrIbv8IeKgzw +mySRXFl2KZUk8r8YyCTm4dtf2ZCU5KcUo9TOae1VzywjXFyV+AyOtFYcJ+FjHQag +CjuT4NzmFqlwa4JWXsAtnom7eR+f4jpn3nPW2CYCE/tYxtF9fpGXdXCNaKo8fbsA +FzOkvoPSAeOjDjcKba6Z/mMBb8or1ide06NEu77e8de8rWCEfdGbMGDmdLQaYI6u +/WIY7ALRppqT9WKnAjKGgYkxFeZGGF8D4ARaLJYYJ71DGAKeSkK6RqHqhmWDcSI8 +cLh5WHqzCflQhxjVf5rCF/ASwTnbw0dsClqF35gw+TKAlXc/uhECggEBAOMVwVIR +ZkCvcfH35RGxqMZ/Ca8Viqap5zLY/gL0YTM/HYhRPE8iUutCWGN1SBDQm2yKuk84 +H1Jjj7zTOxIVW0yov1m36KCsF31s8ks1b3uo+yEOyLhGpJPUq8mYAVbl/13Tcwp3 +0zs7oflZxK65vICUreJM9P/BqXJ/Edfddj88uIqjW98XGgTCgCHpFBxKfRzNkmi+ +3TBswZm2yqQ3qcrFN6H7ieUNCgN2Bj6tWlNmB/RCV+stbbEWwXbDlv1M+JNoM/Jw +c1A++csAhx04BphNeKi01W0zEyRt6tlZWqolvhSUTom6xxWtjikqwfad6HMwn09V +8luh5Ote2WNE8JcCggEBAMRQUlYKCTSvHuIscDukLExW+9JVKaufeXZvCuTK94Bs +P0MtAgrHkgXdiRIBBFAViPjadMQitGkwKYd+zRPUmdzTuH9Lamqjl6e8dUpcO+Bf +0scM94Te0gD8Gtv2Uu4Kw75P2RTXHRk9e8VbFpgYvfl9H0Uc8BK8jzlgWPqHgFnB +WUXuMTAcKax4UwXdxWUjyv3xPmDygt7koPqpuX6FKvfxRq50a3TVIFku+8hRQtQR +N+U0ScYrTOClTuc/QE0Q6rmw06lWHmytK3QiVhgpKxdw1xvVyjw5rMbB2eQdz7IQ +2zn/o5+0gYdg/jvamo1HIxKjPCP1Lxm++manmy6kVD0CggEAeDwwm89yoJVEc6WZ +uAClKFRjQDzbqNsU+ytBczcJsCSe8mpw0EWQOdhrDF4wxhZt9M6PTxqcGvd0R7pf +8Hc2XCSNDGf/1/LGjTZ+I6wrVwJl1V8Kj+d3hH56ZscBDo3A5GDs7IH9acNtQ6Vw +KkNVt48Bcmzk2/YiTelR/UXZMipoW5+bKUgGErcZONs8Nq6KCBIgjy1f2B/9cfIC +4WhHkoFRr4aLwKdiwepf7BfFV5sSYxYtjuwCxF0UGln9PCjhBMuLlbZMmBSAFig1 +YhckBsgeNtVom+ULIaLBUkupYaWSOzs7SlmGx8eZGdr10CpTxYndEBiltjbGComx ++ImsCQKCAQBaaX+yHock225Gzh6WaUL5man6sbwyTY0cLYH/4zZfz/rGzmi9XDJ1 +PxVM1GkPFQvzSHE0j6M1Org1rgF3G5gNKvkyryIAoP1MhDAkohv1d0xU3jT03cYs +K++W1HhXJ2AFOzMINRYytK1XNF9QhzyfNa/8HZq3ll4EF8qC/3ruW2zpFw1SUfYj +d3sNHZk2vmhT0hJfhfEeBH/bUeWbTmt+q4FZAUcoFKwERu4w0LQNhSyQBCfh+7k5 +UQjo2amclKj2AmlI+N+kP5DeuJ2cHQG6lv6K1EiCujFHjKn0NIKeSMMekAzklbZ+ +Cf6sxD4fyN5vS/x7twUNP3aFZrXCom4lAoIBABSGp/CGw6xeQDPXvZZ7gpLr5m5P +mp+gS3S2MJZUv+6TEwXgHxnbxt5DMe25RAlqVHTuw9/TVccD6qcERvnhxUFMoscD +5Vg/Hj+D1nPEVxvFgq0xEPI2FcwS6xT8gicV5dsCWIlOY3ZxBzOzByW1iA2YNymj +pNTypqkARnheZZCK+4ortIeczll5XpbyGIXyxfIrKLYyv38gqLwCdb+MJsih91qc +SrijfhjqqK9sr5KyHlPJDI4Mlw//qkPwIiKv70TGsSgu775OyyZFEl3uS+Y4BUGa +dk5d+8OviBYIReMvvyl6U0jFCUK579lEDpEOPDF2C6VvDQ3FyHP7UXaOWrI= +-----END RSA PRIVATE KEY----- === removed file 'legalnotice.xml' --- legalnotice.xml 2017-08-20 16:20:54 +0000 +++ legalnotice.xml 1970-01-01 00:00:00 +0000 @@ -1,28 +0,0 @@ - - - - - This manual page is part of Mandos. - - - - Mandos is free software: you can redistribute it and/or modify it - under the terms of the GNU General Public - License as published by the Free Software Foundation, either - version 3 of the License, or (at your option) any later version. - - - - Mandos is distributed in the hope that it will be useful, but - WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The settings in this file can be overridden by - runtime changes to the server, which it saves across restarts. - (See the section called PERSISTENT STATE in - mandos8.) However, any changes to this file (including adding and removing - clients) will, at startup, override changes done during runtime. - - - The format starts with a [section - header] which is either - [DEFAULT] or [client - name]. The client - name can be anything, and is not tied to a host - name. Following the section header is any number of - option=value entries, - with continuations in the style of RFC 822. option: value is also accepted. Note that - leading whitespace is removed from values. Values can contain - format strings which refer to other values in the same section, - or values in the DEFAULT section (see ). Lines beginning with # - or ; are ignored and may be used to provide - comments. - - - - - OPTIONS - - Note: all option values are subject to - start time expansion, see . - - - Unknown options are ignored. The used options are as follows: - - - - - - - - - This option is optional. - - - How long to wait for external approval before resorting to - use the value. The - default is PT0S, i.e. not to wait. - - - The format of TIME is the same - as for timeout below. - - - - - - - - - This option is optional. - - - How long an external approval lasts. The default is 1 - second. - - - The format of TIME is the same - as for timeout below. - - - - - - - - - Whether to approve a client by default after - the . The default - is True. - - - - - - - - - This option is optional. - - - This option overrides the default shell command that the - server will use to check if the client is still up. Any - output of the command will be ignored, only the exit code - is checked: If the exit code of the command is zero, the - client is considered up. The command will be run using - /bin/sh - , so - PATH will be searched. The default - value for the checker command is fping %%(host)s. Note that - mandos-keygen, when generating output - to be inserted into this file, normally looks for an SSH - server on the Mandos client, and, if it finds one, outputs - a option to check for the - client’s SSH key fingerprint – this is more secure against - spoofing. - - - In addition to normal start time expansion, this option - will also be subject to runtime expansion; see . - - - - - - - - - This option is optional. - - - Extended timeout is an added timeout that is given once - after a password has been sent successfully to a client. - The timeout is by default longer than the normal timeout, - and is used for handling the extra long downtime while a - machine is booting up. Time to take into consideration - when changing this value is file system checks and quota - checks. The default value is 15 minutes. - - - The format of TIME is the same - as for timeout below. - - - - - - - - - This option is required. - - - This option sets the OpenPGP fingerprint that identifies - the public key that clients authenticate themselves with - through TLS. The string needs to be in hexadecimal form, - but spaces or upper/lower case are not significant. - - - - - - - - - This option is optional. - - - This option sets the certificate key ID that identifies - the public key that clients authenticate themselves with - through TLS. The string needs to be in hexadecimal form, - but spaces or upper/lower case are not significant. - - - - - - - - - This option is optional, but highly - recommended unless the - option is modified to a - non-standard value without %%(host)s in it. - - - Host name for this client. This is not used by the server - directly, but can be, and is by default, used by the - checker. See the option. - - - - - - - - - This option is optional. - - - How often to run the checker to confirm that a client is - still up. Note: a new checker will - not be started if an old one is still running. The server - will wait for a checker to complete until the below - timeout occurs, at which - time the client will be disabled, and any running checker - killed. The default interval is 2 minutes. - - - The format of TIME is the same - as for timeout below. - - - - - - - - - This option is only used if is not - specified, in which case this option is - required. - - - Similar to the , except the secret - data is in an external file. The contents of the file - should not be base64-encoded, but - will be sent to clients verbatim. - - - File names of the form ~user/foo/bar - and $ENVVAR/foo/bar - are supported. - - - - - - - - - If this option is not specified, the option is required - to be present. - - - If present, this option must be set to a string of - base64-encoded binary data. It will be decoded and sent - to the client matching the above - or . This should, of course, - be OpenPGP encrypted data, decryptable only by the client. - The program mandos-keygen8 can, using its - option, be used to generate - this, if desired. - - - Note: this value of this option will probably be very - long. A useful feature to avoid having unreadably-long - lines is that a line beginning with white space adds to - the value of the previous line, RFC 822-style. - - - - - - - - - This option is optional. - - - The timeout is how long the server will wait, after a - successful checker run, until a client is disabled and not - allowed to get the data this server holds. By default - Mandos will use 5 minutes. See also the - option. - - - The TIME is specified as an RFC - 3339 duration; for example - P1Y2M3DT4H5M6S meaning - one year, two months, three days, four hours, five - minutes, and six seconds. Some values can be omitted, see - RFC 3339 Appendix A for details. - - - - - - - - - Whether this client should be enabled by default. The - default is true. - - - - - - - - - EXPANSION - - There are two forms of expansion: Start time expansion and - runtime expansion. - - - START TIME EXPANSION - - Any string in an option value of the form - %(foo)s will be replaced by the value of the option - foo either in the same section, or, if it - does not exist there, the [DEFAULT] - section. This is done at start time, when the configuration - file is read. - - - Note that this means that, in order to include an actual - percent character (%) in an option value, two - percent characters in a row (%%) must be - entered. - - - - RUNTIME EXPANSION - - This is currently only done for the checker - option. - - - Any string in an option value of the form - %%(foo)s will be replaced by the value of the attribute - foo of the internal - Client object in the - Mandos server. The currently allowed values for - foo are: - approval_delay, - approval_duration, - created, - enabled, - expires, - key_id, - fingerprint, - host, - interval, - last_approval_request, - last_checked_ok, - last_enabled, - name, - timeout, and, if using - D-Bus, dbus_object_path. - See the source code for details. Currently, none of these attributes - except host are guaranteed - to be valid in future versions. Therefore, please - let the authors know of any attributes that are useful so they - may be preserved to any new versions of this software. - - - Note that this means that, in order to include an actual - percent character (%) in a - checker option, four - percent characters in a row (%%%%) must be - entered. Also, a bad format here will lead to an immediate - but silent run-time fatal exit; debug - mode is needed to expose an error of this kind. - - - - - - - FILES - - The file described here is &CONFPATH; - - - - - BUGS - - The format for specifying times for timeout - and interval is not very good. - - - The difference between - %%(foo)s and - %(foo)s is - obscure. - - - - - - EXAMPLE - - -[DEFAULT] -timeout = PT5M -interval = PT2M -checker = fping -q -- %%(host)s - -# Client "foo" -[foo] -key_id = 788cd77115cd0bb7b2d5e0ae8496f6b48149d5e712c652076b1fd2d957ef7c1f -fingerprint = 7788 2722 5BA7 DE53 9C5A 7CFA 59CF F7CD BD9A 5920 -secret = - hQIOA6QdEjBs2L/HEAf/TCyrDe5Xnm9esa+Pb/vWF9CUqfn4srzVgSu234 - REJMVv7lBSrPE2132Lmd2gqF1HeLKDJRSVxJpt6xoWOChGHg+TMyXDxK+N - Xl89vGvdU1XfhKkVm9MDLOgT5ECDPysDGHFPDhqHOSu3Kaw2DWMV/iH9vz - 3Z20erVNbdcvyBnuojcoWO/6yfB5EQO0BXp7kcyy00USA3CjD5FGZdoQGI - Tb8A/ar0tVA5crSQmaSotm6KmNLhrFnZ5BxX+TiE+eTUTqSloWRY6VAvqW - QHC7OASxK5E6RXPBuFH5IohUA2Qbk5AHt99pYvsIPX88j2rWauOokoiKZo - t/9leJ8VxO5l3wf/U64IH8bkPIoWmWZfd/nqh4uwGNbCgKMyT+AnvH7kMJ - 3i7DivfWl2mKLV0PyPHUNva0VQxX6yYjcOhj1R6fCr/at8/NSLe2OhLchz - dC+Ls9h+kvJXgF8Sisv+Wk/1RadPLFmraRlqvJwt6Ww21LpiXqXHV2mIgq - WnR98YgSvUi3TJHrUQiNc9YyBzuRo0AjgG2C9qiE3FM+Y28+iQ/sR3+bFs - zYuZKVTObqiIslwXu7imO0cvvFRgJF/6u3HNFQ4LUTGhiM3FQmC6NNlF3/ - vJM2hwRDMcJqDd54Twx90Wh+tYz0z7QMsK4ANXWHHWHR0JchnLWmenzbtW - 5MHdW9AYsNJZAQSOpirE4Xi31CSlWAi9KV+cUCmWF5zOFy1x23P6PjdaRm - 4T2zw4dxS5NswXWU0sVEXxjs6PYxuIiCTL7vdpx8QjBkrPWDrAbcMyBr2O - QlnHIvPzEArRQLo= -host = foo.example.org -interval = PT1M - -# Client "bar" -[bar] -key_id = F90C7A81D72D1EA69A51031A91FF8885F36C8B46D155C8C58709A4C99AE9E361 -fingerprint = 3e393aeaefb84c7e89e2f547b3a107558fca3a27 -secfile = /etc/mandos/bar-secret -timeout = PT15M -approved_by_default = False -approval_delay = PT30S - - - - - - SEE ALSO - - intro - 8mandos, - mandos-keygen - 8, - mandos.conf - 5, - mandos - 8, - fping - 8 - - - - - RFC 3339: Date and Time on the Internet: - Timestamps - - - - The time intervals are in the "duration" format, as - specified in ABNF in Appendix A of RFC 3339. - - - - - - - - - - - === removed file 'mandos-ctl' --- mandos-ctl 2019-11-03 19:09:41 +0000 +++ mandos-ctl 1970-01-01 00:00:00 +0000 @@ -1,2535 +0,0 @@ -#!/usr/bin/python3 -bbI -# -*- after-save-hook: (lambda () (let ((command (if (fboundp 'file-local-name) (file-local-name (buffer-file-name)) (or (file-remote-p (buffer-file-name) 'localname) (buffer-file-name))))) (if (= (progn (if (get-buffer "*Test*") (kill-buffer "*Test*")) (process-file-shell-command (format "%s --check" (shell-quote-argument command)) nil "*Test*")) 0) (let ((w (get-buffer-window "*Test*"))) (if w (delete-window w))) (progn (with-current-buffer "*Test*" (compilation-mode)) (display-buffer "*Test*" '(display-buffer-in-side-window)))))); coding: utf-8 -*- -# -# Mandos Monitor - Control and monitor the Mandos server -# -# Copyright © 2008-2019 Teddy Hogeborn -# Copyright © 2008-2019 Björn Påhlsson -# -# This file is part of Mandos. -# -# Mandos is free software: you can redistribute it and/or modify it -# under the terms of the GNU General Public License as published by -# the Free Software Foundation, either version 3 of the License, or -# (at your option) any later version. -# -# Mandos is distributed in the hope that it will be useful, but -# WITHOUT ANY WARRANTY; without even the implied warranty of -# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

For an introduction, see - intro - 8mandos. The Mandos server - uses Zeroconf to announce itself on the local network, and uses - TLS to communicate securely with and to authenticate the - clients. The Mandos server uses IPv6 to allow Mandos clients to - use IPv6 link-local addresses, since the clients will probably - not have any other addresses configured (see ). Any authenticated client is then given - the stored pre-encrypted password for that specific client. - - - - - PURPOSE - - The purpose of this is to enable remote and unattended - rebooting of client host computer with an - encrypted root file system. See for details. - - - - - OPTIONS - - - - - - - Show a help message and exit - - - - - - - NAME - - NAME - - - - - - - - - - - - - - - - - - - - - - - - - - Run the server’s self-tests.

The default level is - WARNING. - - - - - - - - - - - - - - - - - - - - - - - Directory to search for configuration files. Default is - /etc/mandos.

It is a normal server program - and will run in a normal system environment, not in an initial - RAM disk environment. - - - - - NETWORK PROTOCOL - - The Mandos server announces itself as a Zeroconf service of type - _mandos._tcp. The Mandos - client connects to the announced address and port, and sends a - line of text where the first whitespace-separated field is the - protocol version, which currently is - 1. The client and server then - start a TLS protocol handshake with a slight quirk: the Mandos - server program acts as a TLS client while the - connecting Mandos client acts as a TLS server. - The Mandos client must supply a TLS public key, and the key ID - of this public key is used by the Mandos server to look up (in a - list read from clients.conf at start time) - which binary blob to give the client. No other authentication - or authorization is done by the server. - - - Mandos Protocol (Version 1) - - Mandos Client - Direction - Mandos Server - - - - Connect - -> - - - 1\r\n - -> - - - TLS handshake as TLS server - - <-> - TLS handshake as TLS client - - - - Public key (part of TLS handshake) - -> - - - - <- - Binary blob (client will assume OpenPGP data) - - - - <- - Close - -
- - - - CHECKING - - The server will, by default, continually check that the clients - are still up. If a client has not been confirmed as being up - for some time, the client is assumed to be compromised and is no - longer eligible to receive the encrypted password. (Manual - intervention is required to re-enable a client.) The timeout, - extended timeout, checker program, and interval between checks - can be configured both globally and per client; see - mandos-clients.conf - 5. - - - - - APPROVAL - - The server can be configured to require manual approval for a - client before it is sent its secret. The delay to wait for such - approval and the default action (approve or deny) can be - configured both globally and per client; see - mandos-clients.conf - 5. By default all clients - will be approved immediately without delay. - - - This can be used to deny a client its secret if not manually - approved within a specified time. It can also be used to make - the server delay before giving a client its secret, allowing - optional manual denying of this specific client. - - - - - - LOGGING - - The server will send log message with various severity levels to - /dev/log. With the - option, it will log even more messages, - and also show them on the console. - - - - - PERSISTENT STATE - - Client settings, initially read from - clients.conf, are persistent across - restarts, and run-time changes will override settings in - clients.conf. However, if a setting is - changed (or a client added, or removed) in - clients.conf, this will take precedence. - - - - - D-BUS INTERFACE - - The server will by default provide a D-Bus system bus interface. - This interface will only be accessible by the root user or a - Mandos-specific user, if such a user exists. For documentation - of the D-Bus API, see the file DBUS-API. - - - - - EXIT STATUS - - The server will exit with a non-zero exit status only when a - critical error is encountered. - - - - - ENVIRONMENT - - - PATH - - - To start the configured checker (see ), the server uses - /bin/sh, which in turn uses - PATH to search for matching commands if - an absolute path is not given. See - sh1 - . - - - - - - - - FILES - - Use the option to change where - &COMMANDNAME; looks for its configurations - files. The default file names are listed here. - - - - /etc/mandos/mandos.conf - - - Server-global settings. See - mandos.conf - 5 for details. - - - - - /etc/mandos/clients.conf - - - List of clients and client-specific settings. See - mandos-clients.conf - 5 for details. - - - - - /run/mandos.pid - - - The file containing the process id of the - &COMMANDNAME; process started last. - Note: If the /run directory does not - exist, /var/run/mandos.pid will be - used instead. - - - - - /var/lib/mandos - - - Directory where persistent state will be saved. Change - this with the option. See - also the option. - - - - - /dev/log - - - The Unix domain socket to where local syslog messages are - sent. - - - - - /bin/sh - - - This is used to start the configured checker command for - each client. See - mandos-clients.conf - 5 for details. - - - - - - - - BUGS - - This server might, on especially fatal errors, emit a Python - backtrace. This could be considered a feature. - - - There is no fine-grained control over logging and debug output. - - - - - - EXAMPLE - - - Normal invocation needs no options: - - - &COMMANDNAME; - - - - - Run the server in debug mode, read configuration files from - the ~/mandos directory, - and use the Zeroconf service name Test to not - collide with any other official Mandos server on this host: - - - - -&COMMANDNAME; --debug --configdir ~/mandos --servicename Test - - - - - - Run the server normally, but only listen to one interface and - only on the link-local address on that interface: - - - - -&COMMANDNAME; --interface eth7 --address fe80::aede:48ff:fe71:f6f2 - - - - - - - SECURITY - - SERVER - - Running this &COMMANDNAME; server program - should not in itself present any security risk to the host - computer running it. The program switches to a non-root user - soon after startup. - - - - CLIENTS - - The server only gives out its stored data to clients which - does have the correct key ID of the stored key ID. This is - guaranteed by the fact that the client sends its public key in - the TLS handshake; this ensures it to be genuine. The server - computes the key ID of the key itself and looks up the key ID - in its list of clients. The clients.conf - file (see - mandos-clients.conf - 5) - must be made non-readable by anyone - except the user starting the server (usually root). - - - As detailed in , the status of all - client computers will continually be checked and be assumed - compromised if they are gone for too long. - - - For more details on client-side security, see - mandos-client - 8mandos. - - - - - - SEE ALSO - - intro - 8mandos, - mandos-clients.conf - 5, - mandos.conf - 5, - mandos-client - 8mandos, - sh - 1 - - - - - Zeroconf - - - - Zeroconf is the network protocol standard used by clients - for finding this Mandos server on the local network. - - - - - - Avahi - - - - Avahi is the library this server calls to implement - Zeroconf service announcements. - - - - - - GnuTLS - - - - GnuTLS is the library this server uses to implement TLS for - communicating securely with the client, and at the same time - confidently get the client’s public key. - - - - - - RFC 4291: IP Version 6 Addressing - Architecture - - - - - Section 2.2: Text Representation of - Addresses - - - - Section 2.5.5.2: IPv4-Mapped IPv6 - Address - - - - Section 2.5.6, Link-Local IPv6 Unicast - Addresses - - - The clients use IPv6 link-local addresses, which are - immediately usable since a link-local addresses is - automatically assigned to a network interfaces when it - is brought up. - - - - - - - - - RFC 5246: The Transport Layer Security (TLS) - Protocol Version 1.2 - - - - TLS 1.2 is the protocol implemented by GnuTLS. - - - - - - RFC 4880: OpenPGP Message Format - - - - The data sent to clients is binary encrypted OpenPGP data. - - - - - - RFC 7250: Using Raw Public Keys in Transport - Layer Security (TLS) and Datagram Transport Layer Security - (DTLS) - - - - This is implemented by GnuTLS version 3.6.6 and is, if - present, used by this server so that raw public keys can be - used. - - - - - - RFC 6091: Using OpenPGP Keys for Transport Layer - Security (TLS) Authentication - - - - This is implemented by GnuTLS before version 3.6.0 and is, - if present, used by this server so that OpenPGP keys can be - used. - - - - - - - - - - - === removed directory 'network-hooks.d' === removed file 'network-hooks.d/bridge' --- network-hooks.d/bridge 2018-02-08 10:23:55 +0000 +++ network-hooks.d/bridge 1970-01-01 00:00:00 +0000 @@ -1,93 +0,0 @@ -#!/bin/sh -# -# This is an example of a Mandos client network hook.

See for details. - - - - - OPTIONS - - - - - - - This option will add an environment variable setting to - all plugins. This will override any inherited environment - variable. - - - - - - - - - - This option will add an environment variable setting to - the PLUGIN plugin. This will - override any inherited environment variables or - environment variables specified using - . - - - - - - - - - - Pass some options to all plugins. - OPTIONS is a comma separated - list of options. This is not a very useful option, except - for specifying the - option to all plugins. - - - - - - - - - - Pass some options to a specific plugin. PLUGIN is the name (file basename) of a - plugin, and OPTIONS is a comma - separated list of options. - - - Note that since options are not split on whitespace, the - way to pass, to the plugin - foo, the option - with the option argument - baz is either - --options-for=foo:--bar=baz or - --options-for=foo:--bar,baz. Using - --options-for="foo:--bar baz". will - not work. - - - - - - - - - - Disable the plugin named - PLUGIN. The plugin will not be - started. - - - - - - - - - - Re-enable the plugin named - PLUGIN. This is only useful to - undo a previous option, maybe - from the configuration file. - - - - - - - - - Change to group ID ID on - startup. The default is 65534. All plugins will be - started using this group ID. Note: - This must be a number, not a name. - - - - - - - - - Change to user ID ID on - startup. The default is 65534. All plugins will be - started using this user ID. Note: - This must be a number, not a name. - - - - - - - - - Specify a different plugin directory. The default is - /lib/mandos/plugins.d, which will - exist in the initial RAM disk - environment. - - - - - - - - - Specify a different plugin helper directory. The default - is /lib/mandos/plugin-helpers, which - will exist in the initial RAM disk - environment. (This will simply be passed to all plugins - via the MANDOSPLUGINHELPERDIR environment - variable. See ) - - - - - - - - - Specify a different file to read additional options from. - See . Other command line options - will override options specified in the file. - - - - - - - - - Enable debug mode. This will enable a lot of output to - standard error about what the program is doing. The - program will still perform all other functions normally. - The default is to not run in debug - mode. - - - The plugins will not be affected by - this option. Use - - if complete debugging eruption is desired. - - - - - - - - - - Gives a help message about options and their meanings. - - - - - - - - - Gives a short usage message. - - - - - - - - - - Prints the program version. - - - - - - - - OVERVIEW - - - This program will run on the client side in the initial - RAM disk environment, and is responsible for - getting a password. It does this by running plugins, one of - which will normally be the actual client program communicating - with the server. - - - - PLUGINS - - This program will get a password by running a number of - plugins, which are simply executable - programs in a directory in the initial RAM - disk environment. The default directory is - /lib/mandos/plugins.d, but this can be - changed with the option. The - plugins are started in parallel, and the first plugin to output - a password and exit with a successful exit - code will make this plugin-runner output the password from that - plugin, stop any other plugins, and exit. - - - - WRITING PLUGINS - - A plugin is simply a program which prints a password to its - standard output and then exits with a successful (zero) exit - status. If the exit status is not zero, any output on - standard output will be ignored by the plugin runner. Any - output on its standard error channel will simply be passed to - the standard error of the plugin runner, usually the system - console. - - - If the password is a single-line, manually entered passprase, - a final trailing newline character should - not be printed. - - - The plugin will run in the initial RAM disk environment, so - care must be taken not to depend on any files or running - services not available there. Any helper executables required - by the plugin (which are not in the PATH) can - be placed in the plugin helper directory, the name of which - will be made available to the plugin via the - MANDOSPLUGINHELPERDIR environment variable. - - - The plugin must exit cleanly and free all allocated resources - upon getting the TERM signal, since this is what the plugin - runner uses to stop all other plugins when one plugin has - output a password and exited cleanly. - - - The plugin must not use resources, like for instance reading - from the standard input, without knowing that no other plugin - is also using it. - - - It is useful, but not required, for the plugin to take the - option. - - - - - - FALLBACK - - If no plugins succeed, this program will, as a fallback, ask for - a password on the console using getpass3, - and output it. This is not meant to be the normal mode of - operation, as there is a separate plugin for getting a password - from the console. - - - - - EXIT STATUS - - Exit status of this program is zero if no errors were - encountered, and otherwise not. The fallback (see ) may or may not have succeeded in either - case. - - - - - ENVIRONMENT - - This program does not use any environment variables itself, it - only passes on its environment to all the plugins. The - environment passed to plugins can be modified using the - and - options. Also, the option - will affect the environment variable - MANDOSPLUGINHELPERDIR for the plugins. - - - - - FILES - - - - /conf/conf.d/mandos/plugin-runner.conf - - - Since this program will be run as a keyscript, there is - little to no opportunity to pass command line arguments - to it. Therefore, it will also - read this file and use its contents as - whitespace-separated command line options. Also, - everything from a # character to the end - of a line is ignored. - - - This program is meant to run in the initial RAM disk - environment, so that is where this file is assumed to - exist. The file does not need to exist in the normal - file system. - - - This file will be processed before - the normal command line options, so the latter can - override the former, if need be. - - - This file name is the default; the file to read for - arguments can be changed using the - option. - - - - - /lib/mandos/plugins.d - - - The default plugin directory; can be changed by the - option. - - - - - /lib/mandos/plugin-helpers - - - The default plugin helper directory; can be changed by - the option. - - - - - - - - - BUGS - - The option is ignored when - specified from within a configuration file. - - - - - - EXAMPLE - - - Normal invocation needs no options: - - - &COMMANDNAME; - - - - - Run the program, but not the plugins, in debug mode: - - - - - &COMMANDNAME; --debug - - - - - - Run all plugins, but run the foo plugin in - debug mode: - - - - - &COMMANDNAME; --options-for=foo:--debug - - - - - - Run all plugins, but not the program, in debug mode: - - - - - &COMMANDNAME; --global-options=--debug - - - - - - Read a different configuration file, run plugins from a - different directory, specify an alternate plugin helper - directory and add four options to the - mandos-client - 8mandos plugin: - - - - -cd /etc/keys/mandos; &COMMANDNAME; --config-file=/etc/mandos/plugin-runner.conf --plugin-dir /usr/lib/x86_64-linux-gnu/mandos/plugins.d --plugin-helper-dir /usr/lib/x86_64-linux-gnu/mandos/plugin-helpers --options-for=mandos-client:--pubkey=pubkey.txt,​--seckey=seckey.txt,​--tls-pubkey=tls-pubkey.pem,​--tls-privkey=tls-privkey.pem - - - - - - SECURITY - - This program will, when starting, try to switch to another user. - If it is started as root, it will succeed, and will by default - switch to user and group 65534, which are assumed to be - non-privileged. This user and group is then what all plugins - will be started as. Therefore, the only way to run a plugin as - a privileged user is to have the set-user-ID or set-group-ID bit - set on the plugin executable file (see - execve2 - ). - - - If this program is used as a keyscript in crypttab5 - , there is a slight risk that if this program - fails to work, there might be no way to boot the system except - for booting from another media and editing the initial RAM disk - image to not run this program. This is, however, unlikely, - since the password-prompt8mandos - plugin will read a password from the console in - case of failure of the other plugins, and this plugin runner - will also, in case of catastrophic failure, itself fall back to - asking and outputting a password on the console (see ). - - - - - SEE ALSO - - intro - 8mandos, - cryptsetup - 8, - crypttab - 5, - execve - 2, - mandos - 8, - password-prompt - 8mandos, - mandos-client - 8mandos - - - - - - - - - === removed file 'plugins.d/askpass-fifo.c' --- plugins.d/askpass-fifo.c 2019-02-11 07:06:55 +0000 +++ plugins.d/askpass-fifo.c 1970-01-01 00:00:00 +0000 @@ -1,227 +0,0 @@ -/* -*- coding: utf-8 -*- */ -/* - * Askpass-FIFO - Read a password from a FIFO and output it - * - * Copyright © 2008-2019 Teddy Hogeborn - * Copyright © 2008-2019 Björn Påhlsson - * - * This file is part of Mandos. - * - * Mandos is free software: you can redistribute it and/or modify it - * under the terms of the GNU General Public License as published by - * the Free Software Foundation, either version 3 of the License, or - * (at your option) any later version. - * - * Mandos is distributed in the hope that it will be useful, but - * WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

In slightly more detail, this client program - brings up network interfaces, uses the interfaces’ IPv6 - link-local addresses to get network connectivity, uses Zeroconf - to find servers on the local network, and communicates with - servers using TLS with a raw public key to ensure authenticity - and confidentiality. This client program keeps running, trying - all servers on the network, until it receives a satisfactory - reply or a TERM signal. After all servers have been tried, all - servers are periodically retried. If no servers are found it - will wait indefinitely for new servers to appear. - - - The network interfaces are selected like this: If any interfaces - are specified using the option, - those interface are used. Otherwise, - &COMMANDNAME; will use all interfaces that - are not loopback interfaces, are not point-to-point interfaces, - are capable of broadcasting and do not have the NOARP flag (see - netdevice - 7). (If the - option is used, point-to-point - interfaces and non-broadcast interfaces are accepted.) If any - used interfaces are not up and running, they are first taken up - (and later taken down again on program exit). - - - Before network interfaces are selected, all network - hooks are run; see . - - - This program is not meant to be run directly; it is really meant - to run as a plugin of the Mandos - plugin-runner - 8mandos, which runs in the - initial RAM disk environment because it is - specified as a keyscript in the - crypttab5 - file. - - - - - PURPOSE - - The purpose of this is to enable remote and unattended - rebooting of client host computer with an - encrypted root file system. See for details. - - - - - OPTIONS - - This program is commonly not invoked from the command line; it - is normally started by the Mandos - plugin runner, see plugin-runner8mandos - . Any command line options this program accepts - are therefore normally provided by the plugin runner, and not - directly. - - - - - - - - - Do not use Zeroconf to locate servers. Connect directly - to only one specified Mandos - server. Note that an IPv6 address has colon characters in - it, so the last colon character is - assumed to separate the address from the port number. - - - Normally, Zeroconf would be used to locate Mandos servers, - in which case this option would only be used when testing - and debugging. - - - - - - - - - - Comma separated list of network interfaces that will be - brought up and scanned for Mandos servers to connect to. - The default is the empty string, which will automatically - use all appropriate interfaces. - - - If the option is used, and - exactly one interface name is specified (except - none), this specifies - the interface to use to connect to the address given. - - - Note that since this program will normally run in the - initial RAM disk environment, the interface must be an - interface which exists at that stage. Thus, the interface - can normally not be a pseudo-interface such as - br0 or tun0; such interfaces - will not exist until much later in the boot process, and - can not be used by this program, unless created by a - network hook — see . - - - NAME can be the string - none; this will make - &COMMANDNAME; only bring up interfaces - specified before this string. This - is not recommended, and only meant for advanced users. - - - - - - - - - - OpenPGP public key file name. The default name is - /conf/conf.d/mandos/pubkey.txt. - - - - - - - - - - OpenPGP secret key file name. The default name is - /conf/conf.d/mandos/seckey.txt. - - - - - - - - - - TLS raw public key file name. The default name is - /conf/conf.d/mandos/tls-pubkey.pem. - - - - - - - - - - TLS secret key file name. The default name is - /conf/conf.d/mandos/tls-privkey.pem. - - - - - - - - - - - - - - - - Sets the number of bits to use for the prime number in the - TLS Diffie-Hellman key exchange. The default value is - selected automatically based on the GnuTLS security - profile set in its priority string. Note that if the - option is used, the values - from that file will be used instead. - - - - - - - - - Specifies a PEM-encoded PKCS#3 file to read the parameters - needed by the TLS Diffie-Hellman key exchange from. If - this option is not given, or if the file for some reason - could not be used, the parameters will be generated on - startup, which will take some time and processing power. - Those using servers running under time, power or processor - constraints may want to generate such a file in advance - and use this option. - - - - - - - - - After bringing a network interface up, the program waits - for the interface to arrive in a running - state before proceeding. During this time, the kernel log - level will be lowered to reduce clutter on the system - console, alleviating any other plugins which might be - using the system console. This option sets the upper - limit of seconds to wait. The default is 2.5 seconds. - - - - - - - - - All Mandos servers are tried repeatedly until a password - is received. This value specifies, in seconds, how long - between each successive try for the same - server. The default is 10 seconds. - - - - - - - - - Network hook directory. The default directory is - /lib/mandos/network-hooks.d. - - - - - - - - - Enable debug mode. This will enable a lot of output to - standard error about what the program is doing. The - program will still perform all other functions normally. - - - It will also enable debug mode in the Avahi and GnuTLS - libraries, making them print large amounts of debugging - output. - - - - - - - - - - Gives a help message about options and their meanings. - - - - - - - - - Gives a short usage message. - - - - - - - - - - Prints the program version. - - - - - - - - OVERVIEW - - - This program is the client part. It is a plugin started by - plugin-runner - 8mandos which will run in - an initial RAM disk environment. - - - This program could, theoretically, be used as a keyscript in - /etc/crypttab, but it would then be - impossible to enter a password for the encrypted root disk at - the console, since this program does not read from the console - at all. This is why a separate plugin runner ( - plugin-runner - 8mandos) is used to run - both this program and others in in parallel, - one of which ( - password-prompt - 8mandos) will prompt for - passwords on the system console. - - - - - EXIT STATUS - - This program will exit with a successful (zero) exit status if a - server could be found and the password received from it could be - successfully decrypted and output on standard output. The - program will exit with a non-zero exit status only if a critical - error occurs. Otherwise, it will forever connect to any - discovered Mandos servers, trying to - get a decryptable password and print it. - - - - - ENVIRONMENT - - - MANDOSPLUGINHELPERDIR - - - This environment variable will be assumed to contain the - directory containing any helper executables. The use and - nature of these helper executables, if any, is purposely - not documented. - - - - - - This program does not use any other environment variables, not - even the ones provided by cryptsetup8 - . - - - - - NETWORK HOOKS - - If a network interface like a bridge or tunnel is required to - find a Mandos server, this requires the interface to be up and - running before &COMMANDNAME; starts looking - for Mandos servers. This can be accomplished by creating a - network hook program, and placing it in a special - directory. - - - Before the network is used (and again before program exit), any - runnable programs found in the network hook directory are run - with the argument start or - stop. This should bring up or - down, respectively, any network interface which - &COMMANDNAME; should use. - - - REQUIREMENTS - - A network hook must be an executable file, and its name must - consist entirely of upper and lower case letters, digits, - underscores, periods, and hyphens. - - - A network hook will receive one argument, which can be one of - the following: - - - - start - - - This should make the network hook create (if necessary) - and bring up a network interface. - - - - - stop - - - This should make the network hook take down a network - interface, and delete it if it did not exist previously. - - - - - files - - - This should make the network hook print, one - file per line, all the files needed for it to - run. (These files will be copied into the initial RAM - filesystem.) Typical use is for a network hook which is - a shell script to print its needed binaries. - - - It is not necessary to print any non-executable files - already in the network hook directory, these will be - copied implicitly if they otherwise satisfy the name - requirements. - - - - - modules - - - This should make the network hook print, on - separate lines, all the kernel modules needed - for it to run. (These modules will be copied into the - initial RAM filesystem.) For instance, a tunnel - interface needs the - tun module. - - - - - - The network hook will be provided with a number of environment - variables: - - - - MANDOSNETHOOKDIR - - - The network hook directory, specified to - &COMMANDNAME; by the - option. Note: this - should always be used by the - network hook to refer to itself or any files in the hook - directory it may require. - - - - - DEVICE - - - The network interfaces, as specified to - &COMMANDNAME; by the - option, combined to one - string and separated by commas. If this is set, and - does not contain the interface a hook will bring up, - there is no reason for a hook to continue. - - - - - MODE - - - This will be the same as the first argument; - i.e. start, - stop, - files, or - modules. - - - - - VERBOSITY - - - This will be the 1 if - the option is passed to - &COMMANDNAME;, otherwise - 0. - - - - - DELAY - - - This will be the same as the - option passed to &COMMANDNAME;. Is - only set if MODE is - start or - stop. - - - - - CONNECT - - - This will be the same as the - option passed to &COMMANDNAME;. Is - only set if is passed and - MODE is - start or - stop. - - - - - - A hook may not read from standard input, and should be - restrictive in printing to standard output or standard error - unless VERBOSITY is - 1. - - - - - - FILES - - - /conf/conf.d/mandos/pubkey.txt - /conf/conf.d/mandos/seckey.txt - - - OpenPGP public and private key files, in ASCII - Armor format.

This encrypted data - which will be stored in a server can only be decrypted by the - OpenPGP key, and the data will only be given out to those - clients who can prove they actually have that key. This key, - however, is stored unencrypted on the client side in its initial - RAM disk image file system. This is normally - readable by all, but this is normally fixed during installation - of this program; file permissions are set so that no-one is able - to read that file. - - - The only remaining weak point is that someone with physical - access to the client hard drive might turn off the client - computer, read the OpenPGP and TLS keys directly from the hard - drive, and communicate with the server. To safeguard against - this, the server is supposed to notice the client disappearing - and stop giving out the encrypted data. Therefore, it is - important to set the timeout and checker interval values tightly - on the server. See mandos8. - - - It will also help if the checker program on the server is - configured to request something from the client which can not be - spoofed by someone else on the network, like SSH server key - fingerprints, and unlike unencrypted ICMP - echo (ping) replies. - - - Note: This makes it completely insecure to - have Mandos clients which dual-boot - to another operating system which is not - trusted to keep the initial RAM disk image - confidential. - - - - - SEE ALSO - - intro - 8mandos, - cryptsetup - 8, - crypttab - 5, - mandos - 8, - password-prompt - 8mandos, - plugin-runner - 8mandos - - - - - Zeroconf - - - - Zeroconf is the network protocol standard used for finding - Mandos servers on the local network. - - - - - - Avahi - - - - Avahi is the library this program calls to find Zeroconf - services. - - - - - - GnuTLS - - - - GnuTLS is the library this client uses to implement TLS for - communicating securely with the server, and at the same time - send the public key to the server. - - - - - - GPGME - - - - GPGME is the library used to decrypt the OpenPGP data sent - by the server. - - - - - - RFC 4291: IP Version 6 Addressing - Architecture - - - - - Section 2.2: Text Representation of - Addresses - - - - Section 2.5.5.2: IPv4-Mapped IPv6 - Address - - - - Section 2.5.6, Link-Local IPv6 Unicast - Addresses - - - This client uses IPv6 link-local addresses, which are - immediately usable since a link-local addresses is - automatically assigned to a network interface when it - is brought up. - - - - - - - - - RFC 5246: The Transport Layer Security (TLS) - Protocol Version 1.2 - - - - TLS 1.2 is the protocol implemented by GnuTLS. - - - - - - RFC 4880: OpenPGP Message Format - - - - The data received from the server is binary encrypted - OpenPGP data. - - - - - - RFC 7250: Using Raw Public Keys in Transport - Layer Security (TLS) and Datagram Transport Layer Security - (DTLS) - - - - This is implemented by GnuTLS in version 3.6.6 and is, if - present, used by this program so that raw public keys can be - used. - - - - - - RFC 6091: Using OpenPGP Keys for Transport Layer - Security - - - - This is implemented by GnuTLS before version 3.6.0 and is, - if present, used by this program so that OpenPGP keys can be - used. - - - - - - - - - - - - === renamed file 'plugins.d/mandos-client.c' => 'plugins.d/mandosclient.c' --- plugins.d/mandos-client.c 2019-02-11 05:14:10 +0000 +++ plugins.d/mandosclient.c 2008-07-31 19:48:05 +0000 @@ -1,6 +1,6 @@ /* -*- coding: utf-8 -*- */ /* - * Mandos-client - get and decrypt data from a Mandos server + * Mandos client - get and decrypt data from a Mandos server * * This program is partly derived from an example program for an Avahi * service browser, downloaded from @@ -9,107 +9,36 @@ * "browse_callback", and parts of "main". * * Everything else is - * Copyright © 2008-2019 Teddy Hogeborn - * Copyright © 2008-2019 Björn Påhlsson - * - * This file is part of Mandos. - * - * Mandos is free software: you can redistribute it and/or modify it - * under the terms of the GNU General Public License as published by - * the Free Software Foundation, either version 3 of the License, or - * (at your option) any later version. - * - * Mandos is distributed in the hope that it will be useful, but + * Copyright © 2007-2008 Teddy Hogeborn & Björn Påhlsson + * + * This program is free software: you can redistribute it and/or + * modify it under the terms of the GNU General Public License as + * published by the Free Software Foundation, either version 3 of the + * License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, but * WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This program is - really meant to run as a plugin in the Mandos client-side system, where it is used as a - fallback and alternative to retrieving passwords from a - Mandos server. - - - This program is little more than a getpass3 - wrapper, although actual use of that function is not guaranteed - or implied. - - - This program tries to detect if a Plymouth daemon - (plymouthd8) - is running, by looking for a - /run/plymouth/pid file or a process named - plymouthd. If it is detected, - this process will immediately exit without doing anything. - - - - - OPTIONS - - This program is commonly not invoked from the command line; it - is normally started by the Mandos - plugin runner, see plugin-runner8mandos - . Any command line options this program accepts - are therefore normally provided by the plugin runner, and not - directly. - - - - - - - - - Prefix string shown before the password prompt. - - - - - - - - - The password prompt. Using this option will make this - program ignore the CRYPTTAB_SOURCE and - CRYPTTAB_NAME environment variables. - - - - - - - - - Enable debug mode. This will enable a lot of output to - standard error about what the program is doing. The - program will still perform all other functions normally. - - - - - - - - - - Gives a help message about options and their meanings. - - - - - - - - - Gives a short usage message. - - - - - - - - - - Prints the program version. - - - - - - - - EXIT STATUS - - If exit status is 0, the output from the program is the password - as it was read. Otherwise, if exit status is other than 0, the - program has encountered an error, and any output so far could be - corrupt and/or truncated, and should therefore be ignored. - - - - - ENVIRONMENT - - - CRYPTTAB_SOURCE - CRYPTTAB_NAME - - - If set, and if the option is not - used, these environment variables will be assumed to - contain the source device name and the target device - mapper name, respectively, and will be shown as part of - the prompt. - - - These variables will normally be inherited from - plugin-runner - 8mandos, which might - have in turn inherited them from its calling process. - - - This behavior is meant to exactly mirror the behavior of - askpass, the default password prompter - from initramfs-tools. - - - - - - - - BUGS - - - - - EXAMPLE - - Note that normally, command line options will not be given - directly, but via options for the Mandos plugin-runner - 8mandos. - - - - Normal invocation needs no options: - - - &COMMANDNAME; - - - - - Show a prefix before the prompt; in this case, a host name. - It might be useful to be reminded of which host needs a - password, in case of KVM switches, etc. - - - - -&COMMANDNAME; --prefix=host.example.org: - - - - - - Run in debug mode. - - - - &COMMANDNAME; --debug - - - - - - SECURITY - - On its own, this program is very simple, and does not exactly - present any security risks. The one thing that could be - considered worthy of note is this: This program is meant to be - run by plugin-runner8mandos - , and will, when run standalone, outside, in a - normal environment, immediately output on its standard output - any presumably secret password it just received. Therefore, - when running this program standalone (which should never - normally be done), take care not to type in any real secret - password by force of habit, since it would then immediately be - shown as output. - - - To further alleviate any risk of being locked out of a system, - the plugin-runner - 8mandos has a fallback - mode which does the same thing as this program, only with less - features. - - - - - SEE ALSO - - intro - 8mandos, - mandos-client - 8mandos, - plugin-runner - 8mandos, - plymouthd - 8 - - - - - - - - === removed file 'plugins.d/plymouth.c' --- plugins.d/plymouth.c 2019-07-27 10:11:45 +0000 +++ plugins.d/plymouth.c 1970-01-01 00:00:00 +0000 @@ -1,613 +0,0 @@ -/* -*- coding: utf-8 -*- */ -/* - * Plymouth - Read a password from Plymouth and output it - * - * Copyright © 2010-2019 Teddy Hogeborn - * Copyright © 2010-2019 Björn Påhlsson - * - * This file is part of Mandos. - * - * Mandos is free software: you can redistribute it and/or modify it - * under the terms of the GNU General Public License as published by - * the Free Software Foundation, either version 3 of the License, or - * (at your option) any later version. - * - * Mandos is distributed in the hope that it will be useful, but - * WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

If no usplash8 - process can be found, this program will immediately exit with an - exit code indicating failure. - - - This program is not very useful on its own. This program is - really meant to run as a plugin in the Mandos client-side system, where it is used as a - fallback and alternative to retrieving passwords from a - Mandos server. - - - If this program is killed (presumably by - plugin-runner - 8mandos because some other - plugin provided the password), it cannot tell - usplash8 - to abort requesting a password, because - usplash - 8 does not support this. - Therefore, this program will then kill the - running usplash - 8 process and start a - new one using the same command line - arguments as the old one was using. - - - - - OPTIONS - - This program takes no options. - - - - - EXIT STATUS - - If exit status is 0, the output from the program is the password - as it was read. Otherwise, if exit status is other than 0, the - program was interrupted or encountered an error, and any output - so far could be corrupt and/or truncated, and should therefore - be ignored. - - - - - ENVIRONMENT - - - cryptsource - crypttarget - - - If set, these environment variables will be assumed to - contain the source device name and the target device - mapper name, respectively, and will be shown as part of - the prompt. - - - These variables will normally be inherited from - plugin-runner - 8mandos, which might - have in turn inherited them from its calling process. - - - This behavior is meant to exactly mirror the behavior of - askpass, the default password prompter. - - - - - - - - FILES - - - /dev/.initramfs/usplash_fifo - - - This is the FIFO to where this program - will write the commands for usplash8 - . See fifo7 - . - - - - - /dev/.initramfs/usplash_outfifo - - - This is the FIFO where this program - will read the password from usplash8 - . See fifo7 - . - - - - - /proc - - - To find the running usplash8 - , this directory will be searched for - numeric entries which will be assumed to be directories. - In all those directories, the exe and - cmdline entries will be used to - determine the name of the running binary, effective user - and group ID, and the command line - arguments. See proc5 - . - - - - - /sbin/usplash - - - This is the name of the binary which will be searched for - in the process list. See usplash8 - . - - - - - - - - BUGS - - Killing usplash - 8 and starting a new one - is ugly, but necessary as long as it does not support aborting a - password request. - - - - - - EXAMPLE - - Note that normally, this program will not be invoked directly, - but instead started by the Mandos plugin-runner8mandos - . - - - - This program takes no options. - - - &COMMANDNAME; - - - - - - SECURITY - - If this program is killed by a signal, it will kill the process - ID which at the start of this program was - determined to run usplash8 - as root (see also ). There is a very - slight risk that, in the time between those events, that process - ID was freed and then taken up by another - process; the wrong process would then be killed. Now, this - program can only be killed by the user who started it; see - plugin-runner - 8mandos. This program - should therefore be started by a completely separate - non-privileged user, and no other programs should be allowed to - run as that special user. This means that it is not recommended - to use the user "nobody" to start this program, as other - possibly less trusted programs could be running as "nobody", and - they would then be able to kill this program, triggering the - killing of the process ID which may or may not - be usplash - 8. - - - The only other thing that could be considered worthy of note is - this: This program is meant to be run by - plugin-runner8mandos, and will, when run - standalone, outside, in a normal environment, immediately output - on its standard output any presumably secret password it just - received. Therefore, when running this program standalone - (which should never normally be done), take care not to type in - any real secret password by force of habit, since it would then - immediately be shown as output. - - - - - SEE ALSO - - intro - 8mandos, - fifo - 7, - plugin-runner - 8mandos, - proc - 5, - usplash - 8 - - - - - - - - === renamed file 'mandos.conf' => 'server.conf' --- mandos.conf 2015-07-20 03:03:33 +0000 +++ server.conf 2008-07-29 03:35:39 +0000 @@ -1,53 +1,7 @@ -# This file must have exactly one section named "DEFAULT". -[DEFAULT] - -# These are the default values for the server, uncomment and change -# them if needed. - -# If "interface" is set, the server will only listen to a specific -# network interface. -;interface = - -# If "address" is set, the server will only listen to a specific -# address.
