xwindows to linux box

[thechap]

after firing up xwindows on a win2k laptop and doing a xhost + . Then i telnet to my redhat linux es box but am unable to run graphical applications.
The DISPLAY setting has been set.
The error i get is

Here is the error I get when I try to run emacs:

emacs: Cannot connect to X server 10.1.4.104:0.
Check the DISPLAY environment variable or use `-d'.
Also use the `xhost' program to verify that it is set to permit
connections from your machine.

anyone have any ideas??

Sorry to sidestep your question, but you are aware that emacs runs just fine non-graphically, correct?

[thechap]

Then i guess its non graphical applications as well. All the same the error is the same.

Is your RHEL server set up to accept non-authenticated telnet sessions? Have you tried using SSH instead?

[thechap]

no the server does not accept non authenticated telnet sessions . I am able to connect via telnet after putting in a username and password.

I would be using ssh in this scenario, as TM suggests. "ssh -X hostname".

That aside, what seems to be happening is that you're asking to open an X app on the linux system, which I assume you don't want. DISPLAY=:0 ?

I'm also unclear about the comment "Then i guess its non graphical applications as well". Starting emacs in the shell only, not with X, shouldn't be giving you warnings about X. If it is, then you're not calling it with :

emacs -nw

It's useful to verify that this works.

This is the most convenient way to do this, normally. 'ssh -X ...' forwards all your X traffic along the secure connection.

If you're trying to do this from telnet, you need to be sure there is a route back to your machine from the machine you're logging into, and set your DISPLAY variable accordingly.

something like this:

[user@fred user]$xhost +barney
[user@fred user]$telnet barney
username: user
password:
[user@barney user]$export DISPLAY=fred:0.0
[user@barney user]$emacs

and emacs should display on the local machine.
