<para>
539
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
552
the server program.
