Installation d’une clé ssh sur un serveur distant

Installation d’une clé ssh sur un serveur distant.
1) Installation du paquetage client :

[~] ➔ sudo apt-get install openssh-client

2) Génération des clés publiques et privées:

[~] ➔ ssh-keygen -t dsa -b 1024
Generating public/private dsa key pair.
Enter file in which to save the key (/home/util01/.ssh/id_dsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/util01/.ssh/id_dsa.
Your public key has been saved in /home/util01/.ssh/id_dsa.pub.
The key fingerprint is:
47:63:02:dd:5e:a5:92:0e:eb:80:df:4d:cd:07:3b:6a util01@station
The key's randomart image is:
+--[ DSA 1024]----+
|      .. .   ..  |
|       .. ....   |
|        o.*.o    |
|     .   B.= o   |
|    . . S + = .  |
|     . + + . o   |
|      . o E      |
|         .       |
|                 |

3) Copier la clé publique sur le serveur :

[~] ➔ ssh-copy-id -i ~/.ssh/id_dsa.pub pi@192.168.1.12
pi@192.168.1.12's password:
Now try logging into the machine, with "ssh 'pi@192.168.1.12'", and check in:
  ~/.ssh/authorized_keys
to make sure we haven't added extra keys that you weren't expecting.

4) Connexion vers le serveur distant :
Aucun mot de passe n’est demandé.

[~] ➔ ssh pi@192.168.1.12
