<para>
551
If a client is compromised, its downtime should be duly noted
552
by the server which would therefore declare the client
553
invalid. But if the server was ever restarted, it would
554
re-read its client list from its configuration file and again
555
regard all clients therein as valid, and hence eligible to
556
receive their passwords. Therefore, be careful when
557
restarting servers if it is suspected that a client has, in
558
fact, been compromised by parties who may now be running a
559
fake Mandos client with the keys from the non-encrypted
560
initial <acronym>RAM</acronym> image of the client host. What
561
should be done in that case (if restarting the server program
562
really is necessary) is to stop the server program, edit the
563
configuration file to omit any suspect clients, and restart
564
the server program.
