        If a client is compromised, its downtime should be duly noted
 
517
        by the server which would therefore declare the client
 
518
        invalid.  But if the server was ever restarted, it would
 
519
        re-read its client list from its configuration file and again
 
520
        regard all clients therein as valid, and hence eligible to
 
521
        receive their passwords.  Therefore, be careful when
 
522
        restarting servers if it is suspected that a client has, in
 
523
        fact, been compromised by parties who may now be running a
 
524
        fake Mandos client with the keys from the non-encrypted
 
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
 
528
        configuration file to omit any suspect clients, and restart
