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 dsa key pair. Enter file in which to save the key (/home/kchennen/.ssh/id_dsa): Created directory '/home/kchennen/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /home/kchennen/.ssh/id_dsa. Your public key has been saved in /home/kchennen/.ssh/id_dsa.pub. The key fingerprint is: 93:42:01:20:1a:de:a5:ad:7c:eb:fe:7f:52:e8:a2:a7 kchennen@maurice The key's randomart image is: +--[ DSA 1024]----+ |o ...o. | |oo. + . | |.. o .. | | . .. . | | o .. S . | | . .. o . | | . . . | | . o o . | | .E=.o.o | +-----------------+
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.
