Remote display application on Fedora desktop ?

rcs.raja · 12-28-2010, 03:44 AM

I have an X application. I want to run the application on one box and I want the display to come up on fedora desktop.

I just tried setting DISPLAY environment variable to fedora box's "ip_address:0.0" and ran the application. Its throwing error can't display.

Eg :

# setenv DISPLAY 11.178.59.29:0.0
# xclock
Error: Can't open display: 11.178.59.29:0.0

Could somebody help out on how to do this

Thanks

Not really, since you don't tell us what the CLIENT is running. If the client isn't running X software, or that software hasn't allowed incoming X sessions, you'll get that error. If you're running Linux, make sure X has started without the -nolisten option. Using Windows? Then load an X emulator.

This has been covered MANY times here, so search the old threads for many answers.

Hi Guru,

Client(where xclock is running) and server(where I want display) both are linux boxes.

Looks like my server is not allowing connections. Could you please tell me how to make server allow connections.
Where to set the -nolisten option which you mentioned?
Here Im trying to display gui on default fedora desktop. Can I do that ? Or is there any other method ?

Thanks
Chandu

Again, this has been covered on here MANY times, search the old threads, and you'll find it. And again, you don't say what version of Fedora you're using, what window manager/display manager, etc., so if you don't provide details, you can't get help. There should be a configuration option in your display manager to allow incoming X sessions. If you do a "ps -ef | grep nolisten" at a prompt, you'll be able to tell if you're allowed incoming sessions or not.

you can do this way

ssh -X user1@serverip -C opera

instead of opera you can use kdesktop or konqueror but not firefox
this call remote apps via ssh

if available you can see my sample Remote Apps

I think it's missing one command on the machine where you want the window to pop up:

xhost +

Please look at the xhost man page for detailed info to allow only certain machines ...

Just for Information

Xhost is a very insecure mechanism, Xauth as replacement but
If you use ssh, then you don't need to know anything about xauth. It just works.
further info good to read
