echo $DISPLAY is blank in RH7.3

Trying to run an X application through an SSH session is proving harder than I thought. I would love to have this functionality because then I could run Xapplications from my home machines while at work on my M$ machine...

When I connect to my RH7.3 server however and do an echo $DISPLAY I get a blank row returned. How can I get this to tell me the correct information so when I launch an X application it knows where to send it?

Thanks in advance!

You should just probably go ahead and set the DISPLAY value. It typically is not set when you login via SSH.

You may have your ssh config file set up not to allow X forwarding (man ssh, man sshd for all the nitty gritty). When you issue your ssh command try using the -X option. is the $DISPLAY env variable set now?

Here's another thing that helps when you're trying to figure out what's going on with ssh: use the -v (verbose) option it dumps a lot of stuff on stdout to tell you what's happenin'. really. try it.

Logged in from the terminal and this is even true here - it appears it's not a SSH configuration.

I could set the $DISPLAY, but how do I know WHAT to set it to?
I can use localhost:0.0 but I don't think this is going to help in an SSH session...

Argh...
