First, make sure that you have an X server running on whatever machine you are 
physically on.  The fact that you mention "putty" implies you are logging in 
from a Windows machine.  In that case, make sure that you have cygwin X (or 
something similar) running.  That's absolute KEY to this working.  You *must* 
have an X server running locally.

Second, make sure your sshd on the 'ns1' box allows X forwarding.  I'm not 
sure where it would be on your system, but on my Gentoo box, the file 
is /etc/ssh/sshd_config.  You want to see the line:

X11Forwarding yes

Third, make sure your ssh client knows to forward along the X display and 
offset info.  If you are using a Linux ssh client, then either 'ssh -X' would 
work or setting it permanently in /etc/ssh/ssh_config.  I've never done it on 
putty.

Hope this helps.
