        If a client is compromised, its downtime should be duly noted
 
591
        by the server which would therefore disable the client.  But
 
592
        if the server was ever restarted, it would re-read its client
 
593
        list from its configuration file and again regard all clients
 
594
        therein as enabled, and hence eligible to receive their
 
595
        passwords.  Therefore, be careful when restarting servers if
 
596
        it is suspected that a client has, in fact, been compromised
 
597
        by parties who may now be running a fake Mandos client with
 
598
        the keys from the non-encrypted initial <acronym>RAM</acronym>
 
599
        image of the client host.  What should be done in that case
 
600
        (if restarting the server program really is necessary) is to
 
601
        stop the server program, edit the configuration file to omit
 
602
        any suspect clients, and restart the server program.
