The server will, by default, continually check that the clients
319
328
are still up. If a client has not been confirmed as being up
320
329
for some time, the client is assumed to be compromised and is no
321
longer eligible to receive the encrypted password. The timeout,
330
longer eligible to receive the encrypted password. (Manual
331
intervention is required to re-enable a client.) The timeout,

332
checker program, and interval between checks can be configured
323

both globally and per client; see <citerefentry>

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

<xref linkend="clients"/>.
450
There is currently no way of querying the server of the current

status of clients, other than analyzing its <systemitem

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
546
by the server which would therefore disable the client. But
547
if the server was ever restarted, it would re-read its client
548
list from its configuration file and again regard all clients
549
therein as enabled, and hence eligible to receive their
550
passwords. Therefore, be careful when restarting servers if
551
it is suspected that a client has, in fact, been compromised
552
by parties who may now be running a fake Mandos client with
553
the keys from the non-encrypted initial <acronym>RAM</acronym>
554
image of the client host. What should be done in that case
555
(if restarting the server program really is necessary) is to
556
stop the server program, edit the configuration file to omit
557
any suspect clients, and restart the server program.
