The server will by default provide a D-Bus system bus interface.

Currently, if a client is declared <quote>invalid</quote> due to
443

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

permanent storage. This has some security implications, see

restarting servers if it is suspected that a client has, in
544
523
fact, been compromised by parties who may now be running a
545
524
fake Mandos client with the keys from the non-encrypted
546
initial <acronym>RAM</acronym> image of the client host. What
547
should be done in that case (if restarting the server program
548
really is necessary) is to stop the server program, edit the
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
549
528
configuration file to omit any suspect clients, and restart
550
529
the server program.
