Currently, if a client is declared <quote>invalid</quote> due to
454

having timed out, the server does not record this fact onto

permanent storage. This has some security implications, see

There is currently no way of querying the server of the current

restarting servers if it is suspected that a client has, in
555
540
fact, been compromised by parties who may now be running a
556
541
fake Mandos client with the keys from the non-encrypted
557
initial <acronym>RAM</acronym> image of the client host. What
558
should be done in that case (if restarting the server program
559
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
560
545
configuration file to omit any suspect clients, and restart
561
546
the server program.
