The server will, by default, continually check that the clients
306
351
are still up. If a client has not been confirmed as being up
307
352
for some time, the client is assumed to be compromised and is no
308
longer eligible to receive the encrypted password. The timeout,
353
longer eligible to receive the encrypted password. (Manual
354
intervention is required to re-enable a client.) The timeout,
309
355
checker program, and interval between checks can be configured
310
356
both globally and per client; see <citerefentry>

The server can be configured to require manual approval for a
368
client before it is sent its secret. The delay to wait for such
369
approval and the default action (approve or deny) can be
370
configured both globally and per client; see <citerefentry>

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.

The server will by default provide a D-Bus system bus interface.
398
This interface will only be accessible by the root user or a

Mandos-specific user, if such a user exists. For documentation

Currently, if a client is declared <quote>invalid</quote> due to
422
having timed out, the server does not record this fact onto
423
permanent storage. This has some security implications, see
424
<xref linkend="clients"/>.
427
There is currently no way of querying the server of the current
428
status of clients, other than analyzing its <systemitem
429

499
Currently, if a client is disabled due to having timed out, the
500
server does not record this fact onto permanent storage. This
501
has some security implications, see <xref linkend="clients"/>.

There is no fine-grained control over logging and debug output.

This server does not check the expire time of clients’ OpenPGP
516
588
If a client is compromised, its downtime should be duly noted
517
by the server which would therefore declare the client
518
invalid. But if the server was ever restarted, it would
519
re-read its client list from its configuration file and again
520
regard all clients therein as valid, and hence eligible to
521
receive their passwords. Therefore, be careful when
522
restarting servers if it is suspected that a client has, in
523
fact, been compromised by parties who may now be running a
524
fake Mandos client with the keys from the non-encrypted
525
initial <acronym>RAM</acronym> image of the client host. What
526
should be done in that case (if restarting the server program
527
really is necessary) is to stop the server program, edit the
528
configuration file to omit any suspect clients, and restart
589
by the server which would therefore disable the client. But
590
if the server was ever restarted, it would re-read its client
591
list from its configuration file and again regard all clients
592
therein as enabled, and hence eligible to receive their
593
passwords. Therefore, be careful when restarting servers if
594
it is suspected that a client has, in fact, been compromised
595
by parties who may now be running a fake Mandos client with
596
the keys from the non-encrypted initial <acronym>RAM</acronym>
597
image of the client host. What should be done in that case
598
(if restarting the server program really is necessary) is to
599
stop the server program, edit the configuration file to omit
600
any suspect clients, and restart the server program.
