        If a client is compromised, its downtime should be duly noted
566
 
        by the server which would therefore disable the client.  But
567
 
        if the server was ever restarted, it would re-read its client
568
 
        list from its configuration file and again regard all clients
569
 
        therein as enabled, and hence eligible to receive their
570
 
        passwords.  Therefore, be careful when restarting servers if
571
 
        it is suspected that a client has, in fact, been compromised
572
 
        by parties who may now be running a fake Mandos client with
573
 
        the keys from the non-encrypted initial <acronym>RAM</acronym>
574
 
        image of the client host.  What should be done in that case
575
 
        (if restarting the server program really is necessary) is to
576
 
        stop the server program, edit the configuration file to omit
577
 
        any suspect clients, and restart the server program.
