ssh without user password question

tonyfreeman · 10-25-2004, 09:21 AM

I have a script that "barney" must run. He needs to retrieve some information from "fred''s account on the server via sftp.

Here is the code snipette:

Code:

# FTP data
echo "DOWNLOADING DATA..."
sftp fred@myserver << EOF
	get $my_file
	quit
EOF

I've configured "myserver" so that "fred" doesn't need to provide a password for ssh,scp,sftp,etc. The above code works as expected when ran as "fred" ... but I need to run the script as "barney". When the above code is ran as "barney" I have to provide "fred's" password each time.

Any ideas how can I run the above script as "barney" without having to provide "fred's" password each time?

Public Key authentication. Copy barney's PK into ~fred/.ssh/authorized_keys on myserver. You won't have to enter a password and its MUCH more secure than having users running around without passwords (which is extraordinarily dangerous in this day and age).

Thanks! Sometimes I overlook the simple things :-)

I was trying to do some tricks with echoing the password and also creating a channel and echoing commands to it. This really helped.
