The server will, by default, continually check that the clients
319
350
are still up. If a client has not been confirmed as being up
320
351
for some time, the client is assumed to be compromised and is no
321
longer eligible to receive the encrypted password. The timeout,
352
longer eligible to receive the encrypted password. (Manual
353
intervention is required to re-enable a client.) The timeout,
322
354
checker program, and interval between checks can be configured
323
355
both globally and per client; see <citerefentry>

The server can be configured to require manual approval for a
367
client before it is sent its secret. The delay to wait for such
368
approval and the default action (approve or deny) can be

configured both globally and per client; see <citerefentry>

This can be used to deny a client its secret if not manually

Currently, if a client is declared <quote>invalid</quote> due to
445
having timed out, the server does not record this fact onto
446
permanent storage. This has some security implications, see
447
<xref linkend="clients"/>.
450
There is currently no way of querying the server of the current
451
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
540
by the server which would therefore declare the client
541
invalid. But if the server was ever restarted, it would
542
re-read its client list from its configuration file and again
543
regard all clients therein as valid, and hence eligible to
544
receive their passwords. Therefore, be careful when
545
restarting servers if it is suspected that a client has, in
546
fact, been compromised by parties who may now be running a
547
fake Mandos client with the keys from the non-encrypted
548
initial <acronym>RAM</acronym> image of the client host. What
549
should be done in that case (if restarting the server program
550
really is necessary) is to stop the server program, edit the
551
configuration file to omit any suspect clients, and restart
588
by the server which would therefore disable the client. But
589
if the server was ever restarted, it would re-read its client
590
list from its configuration file and again regard all clients
591
therein as enabled, and hence eligible to receive their
592
passwords. Therefore, be careful when restarting servers if
593
it is suspected that a client has, in fact, been compromised
594
by parties who may now be running a fake Mandos client with
595
the keys from the non-encrypted initial <acronym>RAM</acronym>
596
image of the client host. What should be done in that case
597
(if restarting the server program really is necessary) is to
598
stop the server program, edit the configuration file to omit
599
any suspect clients, and restart the server program.
