Ssh

SSH login without password

It's common to use ssh and scp for communicating and transferring files to and from a server. If you want to auto-login without a password, here's how to setup SSH to use encryption keys to do so.

• Run ssh-keygen to create an encryption key pair, the public and private keys on your PC. You can just hit return for each question.

 maurice:~>  ssh-keygen -t dsa
 [backup@server ~]$ ssh-keygen -t rsa

Generating public/private rsa key pair. Enter file in which to save the key (/home/backup/.ssh/id_rsa): Created directory '/home/backup/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/backup/.ssh/id_rsa. Your public key has been saved in /home/backup/.ssh/id_rsa.pub.
