Running applications remotely with X11

Back to:

I'm using an AIX 4.3 server remotely and a RH linux 7.2 box locally, and trying to make them work together seamlessly.
And this article is a good answer! Though it's good enoght to work, I still expect more detailed things.

I am just starting in Linux (RedHat).
X11 capabilities sound (truly) amazing!
I wonder! .. where does that other OS (MS) stand in relation to the capabilities of x11?
Glad to be using Linux.

Excellent, clearly written article. I was able to follow it step by step, and was successful. This is the best "how-to" explanation of making remote X work. Thank you. FYI - My experimentation was done with two computers running SuSE 7.3. A note on SuSE 7.3 in relation to the article: By default 7.3 installs using (I believe) kdm not xdm. I changed the system startup to xdm prior to trying this.

When I need to connect to another computer at my house I use just this command
in a terminal X :1 -query 192.168.1.??. I dont have to kill my other original
Graphic display the :1 tells it to go to im my case second graphical terminal.
It can be reached by ctrt+alt+F8. If I want another one I can use :2 and the ip
for second remote. Address :3 is also possible

Very good article. The bit about OpenGL helped explain why sometimes,
using a 10Mb network, I see awfully slow response.

Today, I setup lbxproxy (a X compression protocol) and try to work at
home, and find that even I turn to max compression level, it is slow
to catch the event.

I think, it must be worse to use vnc, because it transfer image from
the screen; where lbxproxy transfer X command to the screen. Data of
transfer image must more than X command.

Even though, I try to test vncserver, and the result is: vncserver is
much faster than lbxproxy! I just work like locally! Why will this

I just ask this issue in news group, and the reply that it is because I have enough bandwidth but high network latency, as X is synchronous. I guess it is true because I use ADSL so should have high enough download speed, but 2 computers are far away.

However, is there any method the tune lbxproxy as I would like to use X directly if it is possible.

Open gl, gaming and X, over networks
How fast is open gl/geforce with X? Can I use this for writing/playing 3d games over networks? Any one with experience who knows? It seems like a odd solution, for a game design sending picture information to a gamer, instead of only position, direction, force...

Really a good eye-opener for X windows architecture
From: Dan MacNeil [ date: 2003-07-19 ]
This is helpful.

I have a sense from other resources that it can be a
bit more complicated. I t would be even more helpful
to have pointers to stuff dealing with tunneling,
firewalls & the like.

A co-worker, Unix Guru, setup something like this for me using Hummingbird about 6 or 7 years ago. It all seemed quite mysterious at the time and so did his explanation.

I saw this article and decided to try setting it up myself at home between my Dell Dimension 8100 (1.2GHz) running WinME and a Compaq Desk Pro (266MHz) running Linux 9.0. Bingo! I feel like a budding Unix Guru now. Very clear explanation and gave me enough info to pursue the details. I keep a saved link to the web page on both boxes for on now. Thanks!

A simply put as can be. Thanks Guido.

I ran into one glitch: ssh -X userid@remotehost wouldn't set the remotehost DISPLAY environment variable. I found the error in the "sshd_config" file, where this setting "X11Forwarding no" was default. I changed "no" to "yes", restarted the ssh daemon, and solved the problem. The remotehost with the misconfigured sshd_config was running Slackware 9.1.

Also I tried this technique on Windows 2K with Cygwin/X and it works flawlessly.

I now have superior alternatives to KVM switches and Hummingbird.

Thank you Guido for this documment.
