Create a flar over a ssh tunnel (nfs port forwarding)

Contents

Overview

Small how-to create a flar archive over a ssh tunnel on solaris.

flar ssh

Logon to the ssh proxy server

staf@workstation:~$ ssh -R 3049:destSystem:2049 staf@sshproxy

Logon to the srcSystem

 [swagemak@sshproxy]$ ssh -R 3049:127.0.0.1:3049 root@destSystem

Mount the backup filesystem on the srcHost

 [ROOT@scrSystem] # mount -o port=3049 nfs://localhost/backup /mnt

Verify that the backup file system is mounted

 # df -h

Create the flar

 [ROOT@srcSystem] # cd /mnt
 [ROOT@srcSystem] /mnt # touch boe
 [ROOT@srcSystem] /mnt # flarcreate -S -n srcSystem srcSystem.flar
