ssh authorization

Create a public ssh key, if you haven’t one already. Look at ~/.ssh. If you see a file named id_dsa.pub then you obviously already have a public key. If not, simply create one.

ssh-keygen -t dsa

ItemMake sure your .ssh dir is 700:

chmod 700 ~/.ssh

Get your public ssh key on the server you want to login automatically.

scp ~/.ssh/id_dsa.pub remoteuser@remoteserver.com:

Append the contents of your public key to the ~/.ssh/authorized_keys and remove it. Simply issue something like

cat id_dsa.pub >> .ssh/authorized_keys

Remove your public key from the home directory on the server.
Done!

You can now login without getting asked for a password.

ssh -l remoteuser remoteserver.com or ssh remoteuser@remoteserver.com
