To configure a Linux host client to be backed up, configure SSH from the backup server as follows in order to exchange certificates and to perform a login without passwords.
+
Pour qu'un client hôte Linux soit sauvegardé, configurer SSH du serveur de sauvegarde comme suit de façon à échanger les certificats afin de permettre un accès sans mots de passe.

At the BackupPC server command line as root:
+
Sur le serveur BackupPC, en ligne de commande en tant que «root» :
su -s /bin/bash backuppc
su -s /bin/bash backuppc
−
ssh-keygen -t rsa -b 2048 # use a blank passphrase
+
ssh-keygen -t rsa -b 2048 # utiliser une phrase de passe vide
exit
exit

Assuming SSH access to the remote host to be backed up is already configured, as root:
+
En supposant que l'accès SSH au serveur distant à sauvegarder est déjà configuré, exécuter en tant que «root» :
su -s /bin/bash backuppc
su -s /bin/bash backuppc
−
ssh-copy-id -i ~backuppc/.ssh/id_rsa.pub root@your.host.name
+
ssh-copy-id -i ~backuppc/.ssh/id_rsa.pub root@votre.nom.d_hote
exit
exit

You can test the key exchange:
+
Vous pouvez tester l'échange de clés :
−
su -s /bin/bash backuppc #become backuppc user
+
su -s /bin/bash backuppc #devenir l’utilisateur de backuppc
−
ssh -l root your.host.name # add "-p 2222" for port 2222
+
ssh -l root votre.nom.d_hote # ajouter "-p 2222" pour le port 2222
−
exit #from the remote_host
+
exit #sortir du serveur distant
−
exit #from the backuppc user back to root
+
exit #fermer la session d'utilisateur backuppc pour revenir à «root»
−
You should be able to log in without a password.
+
Vous devriez être capable de vous connecter sans mot de passe.

Note: There are times when the backuppc user needs a real shell specified in /etc/passwd, for example, when the backuppc user is used to run sudo commands or pre/post scripts.<br />
