restarting servers if it is suspected that a client has, in
524
526
fact, been compromised by parties who may now be running a
525
527
fake Mandos client with the keys from the non-encrypted
526
initial <acronym>RAM</acronym> image of the client host. What
527
should be done in that case (if restarting the server program
528
really is necessary) is to stop the server program, edit the
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
529
531
configuration file to omit any suspect clients, and restart
530
532
the server program.
