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

• Overview

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

  

• 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
   Filesystem size used avail capacity Mounted on

• Create the flar
  

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