How to configure RHEL so users can access an app GUI remotely

Question

I have an application installed in my RHEL6 box that has a GUI (AppGui.sh). My problem is that a few non-tech users would like to access this GUI remotely. I've tried several guides over the internet but I still cant make it work.

I tried: -Installing X Window System -Enabling FORWARDX11=yes in my sshd_config -Exporting $DISPLAY variable -Connecting through ssh -X user@host (simply stays there)

How can I setup my box from scratch to make this work?

Answer 1

You could do this the easy way with NoMachine (NX). It's basically compressed X11 over SSH. So all you'll need on the remote side is a client (Mac, Windows, Linux) and to install a server piece on the RHEL6 box you're trying to connect to.

Anything else if going to be a bit slow (raw X11 forwarding), choppy (VNC) or a pain to setup (what you're going through now).

Answer 2

The easiest way for me is to use MobaXterm: you just have to

• Download it here: http://mobaxterm.mobatek.net/download-home-edition.html
• Click on the "new session" button and type your RHEL server name or IP address
• Start the session and run your GUI app.

You have nothing else to do: MobaXterm automatically starts an X11 server and uses X11-Forwarding to display your remote GUI app. This is done without any need for further configuration, so it is very easy.
