529
If a client is compromised, its downtime should be duly noted
530
by the server which would therefore declare the client
531
invalid. But if the server was ever restarted, it would
532
re-read its client list from its configuration file and again
533
regard all clients therein as valid, and hence eligible to
534
receive their passwords. Therefore, be careful when
535
restarting servers if it is suspected that a client has, in
536
fact, been compromised by parties who may now be running a
537
fake Mandos client with the keys from the non-encrypted
538
initial <acronym>RAM</acronym> image of the client host. What
539
should be done in that case (if restarting the server program
540
really is necessary) is to stop the server program, edit the
541
configuration file to omit any suspect clients, and restart
542
the server program.
