<title>APPROVAL</title>
367
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>
371
<refentrytitle>mandos-clients.conf</refentrytitle>
372
<manvolnum>5</manvolnum></citerefentry>. By default all clients
373
will be approved immediately without delay.
376
This can be used to deny a client its secret if not manually
377
approved within a specified time. It can also be used to make
378
the server delay before giving a client its secret, allowing
379
optional manual denying of this specific client.

<title>D-BUS INTERFACE</title>
397
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
399
Mandos-specific user, if such a user exists. For documentation
400
of the D-Bus API, see the file <filename>DBUS-API</filename>.

backtrace. This could be considered a feature.
434
Currently, if a client is declared <quote>invalid</quote> due to
435
having timed out, the server does not record this fact onto
436
permanent storage. This has some security implications, see
437
<xref linkend="clients"/>.
440
There is currently no way of querying the server of the current
441
status of clients, other than analyzing its <systemitem
442
class="service">syslog</systemitem> output.
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"/>.
445
504
There is no fine-grained control over logging and debug output.
529
588
If a client is compromised, its downtime should be duly noted
530
by the server which would therefore declare the client
531
invalid. But if the server was ever restarted, it would
532
re-read its client list from its configuration file and again
533
regard all clients therein as valid, and hence eligible to
534
receive their passwords. Therefore, be careful when
535
restarting servers if it is suspected that a client has, in
536
fact, been compromised by parties who may now be running a
537
fake Mandos client with the keys from the non-encrypted
538
initial <acronym>RAM</acronym> image of the client host. What
539
should be done in that case (if restarting the server program
540
really is necessary) is to stop the server program, edit the
541
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.
