restarting servers if it is suspected that a client has, in
523
533
fact, been compromised by parties who may now be running a
524

fake Mandos client with the keys from the non-encrypted
525
initial RAM image of the client host. What should be done in
526
that case (if restarting the server program really is
527
necessary) is to stop the server program, edit the
535
initial <acronym>RAM</acronym> image of the client host. What
536
should be done in that case (if restarting the server program
537
really is necessary) is to stop the server program, edit the
528
538
configuration file to omit any suspect clients, and restart
529
539
the server program.
