If a client is compromised, its downtime should be duly noted
551
by the server which would therefore disable the client. But
552
if the server was ever restarted, it would re-read its client
553
list from its configuration file and again regard all clients
554
therein as enabled, and hence eligible to receive their
555
passwords. Therefore, be careful when restarting servers if
556
it is suspected that a client has, in fact, been compromised
557
by parties who may now be running a fake Mandos client with
558
the keys from the non-encrypted initial <acronym>RAM</acronym>
559
image of the client host. What should be done in that case
560
(if restarting the server program really is necessary) is to
561
stop the server program, edit the configuration file to omit
562
any suspect clients, and restart the server program.
