Try this:

Code:

shell$ DISPLAY=:0
shell$ export DISPLAY

And, for the IP address:

Code:

shell$ ifconfig

Spell out your words.

And Google could have answered this easily. Type in "export DISPLAY=<ip address>:0"

To find out the IP address, type in "ifconfig -a".

An other way of doing it would be directly in front of the command. In some way, it is a little safer

Code:

DISPLAY=:0 firefox

*Or with an IP

But the real secure way to do it is in a SSH tunel to the XServer directly

Code:

ssh -X user@client_host "my_command"

from the X server

Just for completeness, "setenv" is for csh based shells. You are probably using the bash shell which is from the bourne shell family. Example:

csh

Code:

setenv FOO bar

bourne shell

Code:

export FOO=bar

Thanks Evo2 -- I had wondered from time to time, where `setenv` could come into play, as I had discovered that it didn't work for me in any of my shells.
