    The SSH-1.0-SSH_Version_Mapper is from a scanning tool called scanssh.
    You can find it at http://www.monkey.org/~provos/scanssh/
    
    I've seen a substantial increase in ssh scans over the last month or so.
    Probably a result of the recent vulnerablities listed on CERT.
    
    There seem to be two types of scanning going on, one that looks like
    scanssh.  Then another that's a SYN scan, with a normal reconnect to port
    22 if the first scan found anything open.
