Question : Problem: I can't set the DISPLAY variable successfully

Ihave installed RH4WS 32 bit and I am having a problem not encountered before.
I have a static IP address of 162.182.8.114
If I "echo $DISPLAY" it returns ":0.0"
If I enter "xterm&" an xterm appears
I set the display to 162.182.8.114:0.0
If I "echo $DISPLAY" it returns "162.182.8.114:0.0"
If I enter "xterm&" I get "xterm Xt error: Can't open display: 163.183.8.114:0"
I have tried "xhost +". It makes no difference.
The /etc/hosts file looks like;
127.0.0.1       localhost
162.182.8.114   bslinux
162.182.8.115   billunix
Since I can not specify the DISPLAY successfully, once I ssh or telnet to another machine I can't get an xterm to come up.
Any ideas?

OK, I've got it. You have run your X server with default option: -nolisten tcp.

Do I need to say more ... :)

Go to /etc/X11/...  or wherever you have your X server config file (when you have kde there, it could be eg.
/usr/kde/3.5/share/config/kdm/kdmrc file. It can be a little to search (try to use find /some/dir -name Xsession -print, then look in the directory where this file exists)

What you need is to find where you set this option and remove it. Then restart your X and all should work normally.
