Overview
This page provides a reference for how to setup SSH key-based authentication for BackupPC rsync file transfer backups with NST. Additional information can be found here: BackupPC SSH Setup.
NST BackupPC Client Setup Example For SSH Key-based Authentication
The steps shown below for SSH key-based authentication assumes that the BackupPC user is set to: "backuppc" and the file transfer backup method is: "rsync". The configuration entries from the main BackupPC configuration file: "/etc/BackupPC/config.pl" are shown for these settings.
. . . # # The BackupPC user. # $Conf{BackupPCUser} = 'backuppc'; . . . # # What transport method to use to backup each host. If you have # a mixed set of WinXX and linux/unix hosts you will need to override # this in the per-PC config.pl. # $Conf{XferMethod} = "rsync"; . . .
Step 1: Log In To The backuppc User Account
Since the backuppc user has no login capability, we will need to run the following for access to the backuppc user home directory: "/var/lib/BackupPC" as the backuppc user.
[root@nst-vm ~]# su - backuppc -s /bin/bash;
[backuppc@nst-vm ~]$ pwd;
/var/lib/BackupPC
[backuppc@nst-vm ~]$
Step 2: Generate RSA Key Pairs
Next we will generate a RSA public / private key pair in directory: "var/lib/BackupPC/.ssh".
ssh-keygen -t rsa
ssh root@10.222.222.107
ssh root@10.222.222.107 install -m 700 -d .ssh
cat id_rsa.pub | ssh root@10.222.222.107 tee -a .ssh/authorized_keys
