<para>
549
If a client is compromised, its downtime should be duly noted
550
by the server which would therefore declare the client
551
invalid. But if the server was ever restarted, it would
552
re-read its client list from its configuration file and again
553
regard all clients therein as valid, and hence eligible to
554
receive their passwords. Therefore, be careful when
555
restarting servers if it is suspected that a client has, in
556
fact, been compromised by parties who may now be running a
557
fake Mandos client with the keys from the non-encrypted
558
initial <acronym>RAM</acronym> image of the client host. What
559
should be done in that case (if restarting the server program
560
really is necessary) is to stop the server program, edit the
561
configuration file to omit any suspect clients, and restart
562
the server program.
