514
648
<para>
515
If a client is compromised, its downtime should be duly noted
516
by the server which would therefore declare the client
517
invalid. But if the server was ever restarted, it would
518
re-read its client list from its configuration file and again
519
regard all clients therein as valid, and hence eligible to
520
receive their passwords. Therefore, be careful when
521
restarting servers if it is suspected that a client has, in
522
fact, been compromised by parties who may now be running a
523
fake Mandos client with the keys from the non-encrypted
524
initial <acronym>RAM</acronym> image of the client host. What
525
should be done in that case (if restarting the server program
526
really is necessary) is to stop the server program, edit the
527
configuration file to omit any suspect clients, and restart
528
the server program.
