Using X11 Forwarding

Sometimes you need to install an application in an Unix server from your workstation (windows) and you need to have a display to do that.

You are going to redirect the display of a remote server (Unix server) into a local computer (workstation) using the X Window System (known as X11) which is a computer software system and network protocol that provides a graphical user interface (GUI).

To use this, you need an X11 server running in your workstation, there are several options Xming, Exceed, Cygwin.

X11 Forwarding:

• In the Unix server, enable the following option in the file /etc/ssh/sshd_config

X11Forwarding yes

• Restart ssh service

stopsrc –s sshd; startsrc –s sshd

• Configure putty in the following way 

  


 After you log in, check the DISPLAY and authentification value

echo $DISPLAY
localhost:10.0
xauth list
server/unix:10  MIT-MAGIC-COOKIE-1  e4d497c05f2c1d0bea7d5ca583b76ca1
server/unix:11  MIT-MAGIC-COOKIE-1  0cea5b082451ec11ca4c89b9dc4bc078 

Now, you are ready to start your installation.


Note: Make sure you have installed X11 filesets in the AIX server
