You want to add the -N option: don't execute a remote command (or login in the absence of one). I'd also use -f and -n (I think -f may imply -n but it doesn't hurt ...). That will also put it in background after asking for the password and make sure output is properly redirected, etc. Add those options anywhere before the user@serverB piece. -- Steve Sapovits steves06@comcast.net
