The server will, by default, continually check that the clients
317
351
are still up. If a client has not been confirmed as being up
318
352
for some time, the client is assumed to be compromised and is no
319
longer eligible to receive the encrypted password. The timeout,
353

354
intervention is required to re-enable a client.) The timeout,
320
355
checker program, and interval between checks can be configured
321
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

the server delay before giving a client its secret, allowing

optional manual denying of this specific client.

Currently, if a client is declared <quote>invalid</quote> due to
443
having timed out, the server does not record this fact onto
444
permanent storage. This has some security implications, see

<xref linkend="clients"/>.
448
There is currently no way of querying the server of the current
449
status of clients, other than analyzing its <systemitem

Currently, if a client is disabled due to having timed out, the

If a client is compromised, its downtime should be duly noted
538
by the server which would therefore declare the client
539
invalid. But if the server was ever restarted, it would
540
re-read its client list from its configuration file and again
541
regard all clients therein as valid, and hence eligible to
542
receive their passwords. Therefore, be careful when
543
restarting servers if it is suspected that a client has, in
544
fact, been compromised by parties who may now be running a
545
fake Mandos client with the keys from the non-encrypted
546
initial <acronym>RAM</acronym> image of the client host. What
547
should be done in that case (if restarting the server program
548
really is necessary) is to stop the server program, edit the
549
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.
