SSH using shell scripts

Alek · 08-28-2003, 01:38 PM

I want to ssh from one linux box called Linux1 to another linux box called Linux2 using a shell script. My question is: is there a way to script this so the ssh connection is made without the user intervention of entering the password?
Thanks

You can use public key authentication.

Either use an empty password, or use ssh-agent (with the latter, you must supply the password once before it will work.)

This is a very good tutorial on it:

To set up passwordless logins:
1) login as USER on the client (where you want to connect from)
2) ssh-keygen -t dsa
(don't suppy a passphrase)
3) scp /home/USER/.ssh/id_dsa.pub REMOTEHOST:/home/USER/.ssh/authorized_keys2
(you will need to enter your password this one time)
4) ssh REMOTEHOST
