Hi All,

I am connecting to a LINUX box using putty from a windows box(ssh connection).

I have Xming installed in my machine..my aim is to have GUI for linux.

then i have exported the display like below.

export DISPLAY=my windows machineip:0.0

Next step is in the linux box i ll execute a script which will pop up a configuration window.

Here i am getting the config window or wizard but the problem is ..... its too slow and finally it is getting stuck(config window is loading very slow and diifcult to move forward).

Can anyone tel me why this is happening and how i can tackle this situation.??Any tuning i can make in this.

Please help.

If you connect to Linux with putty, then try enabling X tunneling. Once you do that, $DISPLAY will be automatically set up on the Linux host, and applications needing X will just run. The value of $DISPLAY will be something like 'localhost:10', where the '10' will be some smallish integer value.
If speed is still an issue, try running some tests on the network: simple file transfer speeds using scp for instance. Is the problem restricted to a particular class of applications, or to all programs?

ssh X tunneling does some X protocol compression, so that may help. If you need more improvement look into adding a low bandwidth X proxy (libxproxy) in addition to the ssh tunneling.

In PuTTY do you have 'Enable X11 forwarding' checked. If not, it should be.

When you log in with 'X11 forwarding' you don't have to set DISPLAY. Just echo it and you should see something like 'localhost:10.0'.

If it's still slow, what's the speed of you network connection
Is it over slow DSL

thanks guys for all the suggestions.

but in putty i am enabling the check box -- Enable X11 forwarding.

when i login to the machine and echo DISPLAY it is not giving any value it is blank. ???

Also how can i add a low bandwidth X proxy (libxproxy) in addition to the ssh tunneling

Please let me know.

What shell are you using on the Linux host? Do you have, on the Linux host, '$HOME/.ssh/environment'? If so, what is in it? Do the symptoms appear for all users, or only certain ones? There appears to be some kind of server-side issue. You may have to start the sshd with the -d option, to get some debugging info into the system logs.
