Currently, if a client is declared <quote>invalid</quote> due to
422
443
having timed out, the server does not record this fact onto

Running this <command>&COMMANDNAME;</command> server program

As detailed in <xref linkend="checking"/>, the status of all

restarting servers if it is suspected that a client has, in
523
540
fact, been compromised by parties who may now be running a
524
541
fake Mandos client with the keys from the non-encrypted
525
initial <acronym>RAM</acronym> image of the client host. What
526
should be done in that case (if restarting the server program
527
really is necessary) is to stop the server program, edit the
542
initial RAM image of the client host. What should be done in
543
that case (if restarting the server program really is
544
necessary) is to stop the server program, edit the
528
545
configuration file to omit any suspect clients, and restart
529
546
the server program.
