        If a client is compromised, its downtime should be duly noted
588
 
        by the server which would therefore disable the client.  But
589
 
        if the server was ever restarted, it would re-read its client
590
 
        list from its configuration file and again regard all clients
591
 
        therein as enabled, and hence eligible to receive their
592
 
        passwords.  Therefore, be careful when restarting servers if
593
 
        it is suspected that a client has, in fact, been compromised
594
 
        by parties who may now be running a fake Mandos client with
595
 
        the keys from the non-encrypted initial <acronym>RAM</acronym>
596
 
        image of the client host.  What should be done in that case
597
 
        (if restarting the server program really is necessary) is to
598
 
        stop the server program, edit the configuration file to omit
599
 
        any suspect clients, and restart the server program.
