<para>
526
If a client is compromised, its downtime should be duly noted
527
by the server which would therefore declare the client
528
invalid. But if the server was ever restarted, it would
529
re-read its client list from its configuration file and again
530
regard all clients therein as valid, and hence eligible to
531
receive their passwords. Therefore, be careful when
532
restarting servers if it is suspected that a client has, in
533
fact, been compromised by parties who may now be running a
534
fake Mandos client with the keys from the non-encrypted
535
initial <acronym>RAM</acronym> image of the client host. What
536
should be done in that case (if restarting the server program
537
really is necessary) is to stop the server program, edit the
538
configuration file to omit any suspect clients, and restart
539
the server program.
