Alright guys, I've had this working in Core 2, but I'm having some issues with debian.

All of my applications work great locally, but when I try to run the same applications through SSH from a remote machine, I get two different errors.

When I run a program like Firefox or gksu I get the following error:

Gtk-WARNING **: cannot open display

When I run a java application, i get the following error:

Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.

Can anyone tell me what's going on and how I can fix it?

man xhost
man sshd_config

I can also highly recommend this link and that one.



Cheers,
Tink

I must say, your response here is surprising considering you were very helpful with my last issue. If the answers I need are in the man pages for those two commands, then I am more than happy to find them myself.

For your information, I search this forum and google every time i have a question. When I search the phrase "Gtk-WARNING **: cannot open display" here, there are no hits, and when I search for it on google, I get 1 hit that is in German.

As for you smart ass comments to use the search engines, I would highly recommend you making sure your advice is useful before you give it.

Go on then and read them before you post an
impudent response ;)

Before you make smart ass comments to mods just make
sure you understand how to use the search engines or
know for sure what you're talking about ...

Has it occurred to you that a - or an * in a search phrase may
not yield quite what you intended?

If you remove the -, * and : in the LQ search you get PLENTY
of hits, same on google if you omit the speech-marks.

Being that I am posting this question in the Linux-Newbie area, don't you think this is an important piece of information? If you had included that information with your original post, it would have been MUCH more helpful.

You weren't surprised to not see your own
post listed the second time around?

And this is a Linux-support site, not a "How
to use Google"-board.

Hang on. You originally said

Doesn't that presuppose you knowing the significance of issuing wildcards in search queries and how to use google effectively? The information given to you about man pages for xhost and sshd_config was all the answer you needed. Indeed, had you taken the time to read them you'd already know how to use xhost to change connection rules and you'd be well on your way to solving the problem.
