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
  		/dev/md/dsk/d20        8.8G   1.7G   8.1G    18%    /

  		swap                   512M   369M   143M    73%    /tmp
