 |

Hello,
i have little problem with my X-11 Forwarding and i dont have any ideas, where is the problem.
I am running cygwin with X-term on host machine. Output:

When i try to run gimp i receive following:
| Code: |
foo@bar ~ $ gimp
_X11TransSocketINETConnect() can't get address for localhost:6011: Name or service not known
GIMP could not initialize the graphical user interface.
Make sure a proper setup for your display environment exists.
|
and echo of $DISPLAY:
| Code: |
foo@bar ~ $ echo $DISPLAY
localhost:11.0
|
and my sshd_config on server, on which i connect to:
| Code: |
Port 22
PermitRootLogin no
IgnoreRhosts yes
X11Forwarding yes
TCPKeepAlive yes
ClientAliveInterval 43200
Subsystem sftp /usr/lib/misc/sftp-server
|
Do you have any ideas, what is wrong?
The $DISPLAY seems really strange, but i dont have any ideas, why it is setuped to 11.0
I have removed PAM following this tutorial: http://gentoo-wiki.com/HOWTO_Remove_PAM
Thx for any suggestions
(and sry for my english) |

Have you added the remote system to your xhost?
xhost +ip number |

| You started the Xserver on the cygwin machine ? I think you mihgt have to ssh -X from cygwin to get x forwarding to work. |

You need to run this command on your local machine before you log into the remote system. It tells your local machine to accept X connections from other systems, otherwise your local system rejects the connection.

This is normal and is configurable on the X client (remote) side in the /etc/ssh/sshd_config file. The variable is X11DisplayOffset and it defaults to 10. Each new session will increment that number. :0.0 is the id of the first X session started on a box. This is normally the local GUI running on the machine. SSH starts its sessions up at 10 so as not to interfere with these local sessions.

hmm....Ok, so try something like this:
| Code: |
local $ xhost +
access control disabled, clients can connect from any host
local $ ssh remote
Password:
Last login: Tue May 30 21:25:22 2006
remote $ echo $DISPLAY
localhost:10.0
remote $ xterm &
[1] 28657
remote $
|
and a terminal window should open.

Do you have a X-session running on remote?
When i tried this before (now i have X server broken in cygwin :-/ ), i have retrieving still the same error. The $DISPLAY was containing :
localhost:11.0
EDIT: on remote i have an x session running (its my home computer), so maybe this is the reason why the $DISPLAY contains the 11.0 instead of 10.0... but i am not sure, if its ok. I have fealing, that some months ago, the $DISPLAY was containing localhost:10.0 (when it worked)
P.S.: sorry for my english |

Hello all,
I know this is very late  but it might help someone in the future. I had this issue and all it came down to was in my /etc/hosts file I did not have a localhost definition.
ie:
127.0.0.1 localhost
Hope this helps someone in the future.
Regards
