Generating public/private dsa key pair.
    Enter file in which to save the key (/home/user/.ssh/id_dsa): 
    Enter passphrase (empty for no passphrase): 
    Enter same passphrase again: 
    Your identification has been saved in /home/user/.ssh/id_dsa.
    Your public key has been saved in /home/user/.ssh/id_dsa.pub.
    The key fingerprint is:
    ad:98:43:13:c9:ea:66:8e:d0:d9:66:59:d8:3a:f7:29
    The key's randomart image is:
    +--[ DSA 1024]----+
    |                 |
    |     . .         |
    |      +          |
    |     + . .       |
    |    o = S .      |
    | . + = + .       |
    |. o @ = .        |
    | . B oEo .       |
    |  . .  .o        |

you will get 2 files `id_dsa` and `id_dsa.pub` use scp or other utility to copy file to your server

scp ~/.ssh/id_dsa.pub user@host:~/.ssh/

**On your server**

Add the new key to the file ~/.ssh/authorized\_keys.

cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

chmod 600 ~/.ssh/authorized_keys
    chmod 700 ~/.ssh

chmod 700 ~
