537
648
<para>
538
If a client is compromised, its downtime should be duly noted
539
by the server which would therefore declare the client
540
invalid. But if the server was ever restarted, it would
541
re-read its client list from its configuration file and again
542
regard all clients therein as valid, and hence eligible to
543
receive their passwords. Therefore, be careful when
544
restarting servers if it is suspected that a client has, in
545
fact, been compromised by parties who may now be running a
546
fake Mandos client with the keys from the non-encrypted
547
initial <acronym>RAM</acronym> image of the client host. What
548
should be done in that case (if restarting the server program
549
really is necessary) is to stop the server program, edit the
550
configuration file to omit any suspect clients, and restart
551
the server program.
