        If a client is compromised, its downtime should be duly noted
 
567
        by the server which would therefore disable the client.  But
 
568
        if the server was ever restarted, it would re-read its client
 
569
        list from its configuration file and again regard all clients
 
570
        therein as enabled, and hence eligible to receive their
 
571
        passwords.  Therefore, be careful when restarting servers if
 
572
        it is suspected that a client has, in fact, been compromised
 
573
        by parties who may now be running a fake Mandos client with
 
574
        the keys from the non-encrypted initial <acronym>RAM</acronym>
 
575
        image of the client host.  What should be done in that case
 
576
        (if restarting the server program really is necessary) is to
 
577
        stop the server program, edit the configuration file to omit
 
578
        any suspect clients, and restart the server program.
