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

initial RAM image of the client host. What should be done in

that case (if restarting the server program really is

necessary) is to stop the server program, edit the

initial <acronym>RAM</acronym> image of the client host. What
526
should be done in that case (if restarting the server program

really is necessary) is to stop the server program, edit the

configuration file to omit any suspect clients, and restart

529
the server program.
