[PLUG] Any Win2000 based X server can go through firewall?

[Christopher N. Deckard]

If you are a Purdue Student, Faculty, or Staff you can get either 
PC-XWare or Hummingbird Exceed.

To get it to work behind a firewall, and to do it the right way to begin 
with, you need to tunnel your X apps over SSH.  To do that, go to:

http://www.ssh.com

Download the Windows distribution for SSH v3.x.x.  Install it.  Once 
installed, run the SSH client.  Go to "Edit->Settings" and select 
Tunneling.  On that option screen check the box for Tunnel X-something 
or other".  Save your settings.

Install Exceed.  You will need to configure Exceed to not allow outside 
connections (it enables this by default.)  Go to 
"Start->Programs->Hummingbird->Exceed"  There are two "links" in there 
of importance.  "Exceed", which is the Xserver itself, and "Xconfig" 
which will let you configure the Xserver.  Run Xconfig, go to security, 
then for the "Host Access Control List" option, click "Enabled (no host 
access).  Then click ok.  Close the config program.

To get Xapps (xterm, xemacs, xbill) to display, you will want to fire up 
Exceed, then SSH to the host that you want to run stuff from.  Then run 
your xapps from the SSH window.

This will get around firewall issues, etc.  And your connection to 
whatever machine will be encrypted.

For a "complete" how-to, please look at the following page provided by 
Curtis Smith with the PACE group at Purdue.

You should be able to accomplish the same thing with PC-XWare, but I 
haven't tried it.
