I have connected to my Debian PC with SSH using PuTTY under Windows XP. X11
forwarding is enabled in PuTTY. If I try to start an xwindow application,
the connection is rejected. I've not had any success using Cygwin or XMing.
Both reject the connection the same way, so I assume that the Debian PC is
not configured correctly.

Every time I try to connect to the XServer on my Windows PC, I end up with
the following entry in the XServer log file:

AUDIT: Tue Feb 12 21:49:43 2008: 3868 C:\Program Files\Xming\Xming.exe:
client 4 rejected from IP 10.0.11.16


This is what I see on my Debian SSH session:

steve:~$xeyes
Xlib: connection to "stevespc:0.0" refused by server
Xlib: No protocol specified

Error: Can't open display: stevespc:0.0


Can anyone point me in the right direction to get my remote Debian PC to use
my Windows XServer?

Start cygwin. A command prompt opens. Type 'startx'. (without the '')
Another command prompt opens. This is the X based one. The ssh to
your debian box. Type 'xeyes'. Should open on your windows machine.

I get this far without any problem...

....at this point $DISPLAY is empty.

steve:~$xeyes
Error: Can't open display:

.... I've tried a couple things here with no luck:

steve:~$export DISPLAY=:0.0
steve:~$xeyes

.... It just sits here doing nothing until I hit Ctl-Z.

I also tried the following, which generates "AUDIT: Tue Feb 12 23:15:30
2008: 3476 X: client 6 rejected from IP 10.0.11.16" in the Cygwin "~"
window.

steve:~$export DISPLAY=stevespc:0.0
steve:~$xeyes
Xlib: connection to "stevespc:0.0" refused by server
Xlib: No protocol specified

Error: Can't open display: stevespc:0.0
steve:~$

Looks to me like X forwarding is not working. Note that X forwarding
has to be enabled both on the client and on the server.

Are you using the -X option on your ssh command? ("ssh -X target-
machine-address")
Do you have your SSH server set up to permit X forwarding?

Your sshd_config file should have something like:
X11Forwarding yes
X11DisplayOffset 10
X11UseLocalhost yes

Your ssh command should be
ssh -X target-system-address

You should already have your X server running (I suggest XMing as it
is "lighter" than Cygwin)

You might want to read a Linux Gazette article I wrote that outlines
the things to do: http://linuxgazette.net/129/pitcher.html

Hope this helps.

Thanks!

I was able to get Xming running. I had to add the debian PC to the XO.hosts
file in the Xming directory.
