I communicate with the server via a ssh tunnel, configured via Putty.
Recently, I'm trying to forward the X11 through it, but it doesn't work.
Is there any one work this way?
Searched with google, but didn't find anything.
Yes, this is possible in a few different ways but you will need an X window server for Windows. Some options of a X windows server are XManager, XMing and MobaXterm. Once you have an X server running on Windows you can use PuTTY to connect to your host after you have set the configuration parameters:
Enable X11 forwarding
X display location: localhost:10.0
Where the 10.0 depends on what the X Window server is listening on.
When you configured the X Window server and PuTTY and logged in to your host you can verify the
DISPLAY variable if a
DISPLAY is set:
$ echo $DISPLAY
Then try something like
xclock to see if X11 forwarding works:
# xclock &
Another way to use X11 apart from
ssh is to set the
DISPLAY variable manually to point to an IP address like:
# export DISPLAY=192.168.0.1:0
And see if it works:
# xclock &
This way X applications are (re)directed to output to a remote X Window server.
Note: Keep in mind that the X11 protocol is not designed to operate over slow network (WAN) connections. The X application may be terrible slow when used over slow connections. Consider to use the
-C (compression) switch with
ssh to use compression over the
ssh session to speed it up a little.
Yet another solution is to install Cygwin on your Windows machine. It has both
ssh client and
X11 server (be sure to install the corresponding packages).
Keep in mind that many
X11 installations forbid untrusted X forwarding. Perhaps the simplest way around this is to use
-Y option in
ssh -Y user@server
