Sometimes we need to login through ssh without password. SSH just need the client's public key to be copied on its directory. With this key, ssh recognize the client as a good client or authorized client, not bad client or intruder. To do this, first you need to generate a key.

Use this command to generate ssh key :

$ ssh-keygen -t  dsa

you can let the passphrase empty.

Then copy your ssh public key to your remote computer. You can use this command :

$ scp ~/.ssh/id_dsa.pub user@remote_computer:.ssh/authorized_keys

Its done, now you can login to your remote computer without being asked for a password.
