I don't allow password logins nor do I allow root login. Only to bona 
fide users and only with private keys. Forces the attacker to know a 
*lot* to even begin to mount an attack.

Ok, I can imagine a script that does such. But how do I cross the "su" 
barrier. I issue a command on the client that starts a script on the 
server with several params sent across. But the script is running as me. 
  How I enable it to do su things automatically?

Thanks,
