Yep. I've done so on my laptop/server. If I'm on my laptop and try SSHing to my home server, it just lets me in. You have to make sure RSAAuthentication and PubkeyAuthentication are "yes" on the server's /etc/ssh/sshd_config file (and restart the ssh service). The on the client side, as the user you'll be running SSH from (ie the user I'd normally use on the laptop) run: $ ssh-keygen -t rsa And when prompted for passphrases, just hit enter to continue without setting one. Once the RSA keypair have been generated, you'd then run: $ ssh-copy-id -i /path/to/id_rsa.pub username@server The bit I'm having trouble with is the keygen part - the user account I want to be able to login from is a non-interactive user. :s Grant. -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/linux_adm/list-faq.html
