Are you tired of typing the password all the time when connecting to a ssh-session in unix? I am. The solution is very simple, the only thing you have to do is to add your public RSA-key to the remote user’s keychain.
First you have to generate the public RSA-key of your local user:
ssh-keygen -t rsa
Second you add the key to the remote user’s keychain:
ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
If you can’t
ssh-copy-id use cat to add the key:
cat ~/.ssh/*.pub | ssh [email protected] 'umask 077; cat >>.ssh/authorized_keys'
Now you will be able to engage the connection without typing the password first. If you want this comfort for several users, you have to repeat this procedure for each userpair.
