Hi everyone,

I use KDE desktop (3.5.10) on my Gentoo computer. I'd like to run remote applications on my computer.

remote computer:
[mike@bearcentos ~]$ DISPLAY=192.168.1.7:0.0; export DISPLAY
[mike@bearcentos ~]$ echo $DISPLAY
192.168.1.7:0.0

my Gentoo computer:
mike@gentoobear ~ $ xhost +192.168.1.2
192.168.1.2 being added to access control list

remote computer:
[mike@bearcentos ~]$ xterm
xterm Xt error: Can't open display: 192.168.1.7:0.0

why this is happening...

What elese do I need to do?

Are you doing this through SS, If not that would be the best way !

and also do you got open port on that machine with X ?
if you use iptables or anythin for a firewall you need to open specific port by default it's 6000 i think

http://www.gentoo.org/doc/en/security/security-handbook.xml?full=1 and chapter 10.m X
i guess i was wrong it's turned on by default

did you try

Thankyou, tgR10

I've tried DISPLAY=192.168.1.7:0

It didn't help me

I don't use a firewall.

I am trying to do it over xdmcp. Not over X11 forwading.

the first 0 in :0.0 is the display nr, the second 0 is the display's screen nr. Usually only one 0 is sufficient, but specifying 0.0 shouldn't hurt. What could be the problem is X rejecting remote connections. This is the default behavior for security reasons. Google how you can start X for remote connections. You also need to specify which clients are allowed to connect to the X server in certain configuration files and/or client's need some form of authentication with the X server.

Maybe this can give some insight:
