Xwindows

Message

how do I make it so that Xwindows applications from other computers will work on my gentoo desktop? In windows I first run Xwindows, ssh to the remote machine, and then set my DISPLAY env var to the IP of my machine. When I run an Xwindows application it then pops up on my local screen. How do I get this same behaviour using Xwindows?

Thanks,
Mel

That way doesn't work?

Nop, not for me (I think it should)...

Code: Select all

ssh -X -l name remote_ip
export DISPLAY=local_ip:0

Xlib: connection to "local_ip" refused by server
Xlib: No protocol specified

GTK-WARNING **: cannot open display local_ip:0

? ? ?

Ok, problem solved

. All I had to do was to run xhost +remote_ip and viola - working!

on your local host

Code: Select all

xauth list

Then ssh to your remote host and

Code: Select all

xauth add /cookie/ ; export DISPLAY=/your display/

For example:

Code: Select all

nbensa@venkman nbensa $ xauth list
venkman.bensa.ar:0  MIT-MAGIC-COOKIE-1  335b1e6659335b0b3a663936605c5b59
venkman.bensa.ar/unix:0  MIT-MAGIC-COOKIE-1  335b1e6659335b0b3a663936605c5b59
nbensa@venkman nbensa $ ssh zeddmore
nbensa@zeddmore's password:
Last login: Fri Jan 10 22:51:20 2003 from venkman.bensa.ar
nbensa@zeddmore nbensa $ xauth add venkman.bensa.ar:0  MIT-MAGIC-COOKIE-1  335b1e6659335b0b3a663936605c5b59
nbensa@zeddmore nbensa $ export DISPLAY=venkman.bensa.ar:0

HTH,

I just use the command:

ssh -x username@remotehost.com

and I can use all the x applicaitions I want on the remote host and have them display on my machine (provided I have the program installed on my local machine). Is there some reason I don't know about as to why you use what appears to be a more complicated way?

yep, sure, there's a BIG reason for that much more complicated way...

... I forgot about X forwarding

and that BIG reason would be? i'm a relative newbie to linux, so please forgive me

The reason is: I forgot we were talking about SSH!!! I forgot X forwarding.

I think I need to clarify this: I used to use 'telnet' a lot and 'ssh' is like a new toy for me. I'm using Linux since two years ago, and I'm still learning a lot of things.

I'm sorry for the confusion.
