    this is a heads up to the incidents people (and related @cert and @sans)
    to let you know i have released some modifications i made to niels
    provos' scanssh tool. i made the modifications last fall against version
    1.2a of his scanssh code. the changes add scanning for telnetd and rshd,
    in addition to sshd, to assist network administrators and authorized
    personelle to more fully audit their login methods on their networks.
    
    the biggest change i want people here to know about is the ssh version
    string change:
    
    	SSH-1.1-SSH_Telnet_RSH_Version_Mapper
    
    if you see this its a clear indication that this modified tool has been
    used. it only looks for a valid connection, sends this string, and then
    closes the connection. no other data is exchanged, nothing is logged aside
    from the true or false for a connection for that IP.
    
    thanks.
