restarting servers if it is suspected that a client has, in

555
fact, been compromised by parties who may now be running a

fake Mandos client with the keys from the non-encrypted
528
initial RAM image of the client host. What should be done in
529
that case (if restarting the server program really is
530
necessary) is to stop the server program, edit the
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
531
560
configuration file to omit any suspect clients, and restart
532
561
the server program.
