It is really quite simple:

1. If you are running Panther... install the Xcode package if you haven't already.

2. Open /Applications/Utilities/X11.app

3. In the xterminal window type:

ssh userid@somehost.youruni.edu

4. Once logged in... just enter the name of the X based application that you want to run on the remote machine. It will display locally.

5. If it doesn't work you may have to reconfigure your firewall.

This will not work well over a dial-up connection... you need broadband.

thanks for the quick response, i did exactly what you suggest but the terminal spits out the following message and doesn't open the app

(gaim:11426): Gdk-CRITICAL **: file gdkdisplay-x11.c: line 315 (gdk_display_get_name): assertion `GDK_IS_DISPLAY (display)' failed

** (gaim:11426): WARNING **: cannot open display: unset

[1]+ Exit 1 gaim

i assume that i have to configure something? not sure how to go about this.

1) Log into the remote machine
2) Type "who | grep username", replacing username with your username on the remote host. The IP address of your local machine is on that line.
3) If your remote shell is Bash, Korn, or Bourne shell, type this:


DISPLAY="ip_address:0.0"
export DISPLAY


If your remote shell is csh, or tcsh, type this:


setenv DISPLAY "ip_address:0.0"


In either case, replace ip_address with your IP address from step (2).

4) In a terminal on your local machine type "xhost +"
5) THEN, run your remote program.

Dont't forget to forward the required ports. Use ssh -X username@box to have ssh automatically forward the X11 ports for you.

Hmmm...

I was trying to figure out why I don't have to go through any of this to get remote X11 working. Like I said in my previous post I just start X11 locally on my Mac, ssh to remote machine (no -X, no export this or that), then just type in the command for the X11 based app that I want to run. Then I looked at the sshd_config files on those remote machines and I have:

X11Forwarding yes

instead of the default "no".

Not sure why Apple has this turned off by default.
