        If a client is compromised, its downtime should be duly noted
520
 
        by the server which would therefore declare the client
521
 
        invalid.  But if the server was ever restarted, it would
522
 
        re-read its client list from its configuration file and again
523
 
        regard all clients therein as valid, and hence eligible to
524
 
        receive their passwords.  Therefore, be careful when
525
 
        restarting servers if it is suspected that a client has, in
526
 
        fact, been compromised by parties who may now be running a
527
 
        fake Mandos client with the keys from the non-encrypted
528
 
        initial RAM image of the client host.  What should be done in
529
 
        that case (if restarting the server program really is
530
 
        necessary) is to stop the server program, edit the
