    their boxes are getting similar traffic.  The hack attempts primarily
    try to ssh to root, admin, and a bunch of microsoft-soundy names.  It looks
    fairly coordinated, like it is trying a couple of passwords a each day
    then trying again with different passwords the next day.
Yeah all my boxes have the same, mosty asian IP's though, perhaps it would be nice to have a default something in the system that can be turned on vi rc.conf that whenever there are more then 10 login attemps within 5 minutes that IP gets blocked for say 48 hours?
