On client, generate public and private keys pair:

localusr@client:~$ ssh-keygen -t rsa

Copy public key on the server (create the remote ~/.ssh directory if it does not exists):

localusr@client:~$ cat .ssh/id_rsa.pub | ssh remoteusr@server 'cat >> .ssh/authorized_keys'

Now we can connect to the remote server without password:

localusr@client:~$ ssh remoteusr@server
remoteusr@server:~$
