        If a client is compromised, its downtime should be duly noted
515
 
        by the server which would therefore declare the client
516
 
        invalid.  But if the server was ever restarted, it would
517
 
        re-read its client list from its configuration file and again

        restarting servers if it is suspected that a client has, in
521
 
        fact, been compromised by parties who may now be running a
522
 
        fake Mandos client with the keys from the non-encrypted
