fact, been compromised by parties who may now be running a
556
522
fake Mandos client with the keys from the non-encrypted
557
initial <acronym>RAM</acronym> image of the client host. What
558
should be done in that case (if restarting the server program
559
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
560
526
configuration file to omit any suspect clients, and restart
561
527
the server program.
