If a client is compromised, its downtime should be duly noted
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.
