restarting servers if it is suspected that a client has, in
546
521
fact, been compromised by parties who may now be running a
547
522
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
523
initial RAM image of the client host. What should be done in
524
that case (if restarting the server program really is
525
necessary) is to stop the server program, edit the
551
526
configuration file to omit any suspect clients, and restart
552
527
the server program.
