Kevin,

I thought I'd save you the trouble of looking it up, since I already had
to go through this exercise.

On the remote host:

Edit the sshd_config file:

Uncomment the following line and change no to yes:

#X11Forwarding no

becomes

X11Forwarding yes

and edit the ssh_config file:

Uncomment and change the following lines:

#ForwardAgent no
#ForwardX11 no

to 

ForwardAgent yes
ForwardX11 yes

Finally, make sure that your client is configured to support it as well:

SecureCRT setup –

To set up port forwarding, follow these steps.

   1. Start SecureCRT
   2. Click on File / Connect and select the SSH session for which you
would like to use forwarded ports.
   3. Click on the Session Options button or right-click on the session
and select Properties from the pop-up menu to bring up the Session
Options dialog.
   4. In the Connection category, click on the advanced button and
select the Port Forwarding tab.
   5. Check the Forward X11 Packets option.
   6. OK and exit

Exceed Setup –

   1. Run Exceed’s Xconfig
   2. Choose Communications
   3. Select passive for your mode – click ok
   4. Choose Screen Definition
   5. Under the Screen 0 choose multiple for your window mode
   6. Exit

Put it to the test --

Run Exceed

Connect to your SSH session (as defined above)

At the prompt type xterm

Run an x window (i.e. admintool)
