I tried this method but was unsuccessfull in launching GUI applications on the local system. I checked and made sure that X11Forwarding is set as YES on the remote system. I connect to the remote system using ssh -X .
Now, when i type gedit on the terminal window, the gedit editor open in the remote terminal. Please advice as to what settings i am missing which will enable me to open the GUI on the local system.

Thanks,
vinay

It’s best not to enable X11Forwarding for all connections (i.e. don’t enable it in /etc/ssh/ssh_config)… it used to be the default and there’s a very good reason why it is no longer. It’s dangerous.

It turned out that a remote attacker could sniff your keyboard and mouse movements (or possibly even more horrible things) just because you ssh’d onto a box that they had cracked. In short, it turned into a great way of cracking the next host up the chain.

I generally define two connections in .ssh/config for any machine, say foo.example.com — one connection I call “foo” and the other “xfoo”. I then have X11Forwarding turned on for only one of them. And of course, by using the config file, I can automatically get all the other benefits it brings — I turn on compression and can specify an identity file for pubkey login too.

Could you do an article on installing X on a windows machine. That’s all my university has. Better yet, X on a disk-on-key, like Portable Apps, would be great.

Thanks.

You might also have to throw the “ForwardAgent yes” setting in /etc/ssh/ssh_config in order for this to work. I’ve run into that.

Good tip, though. I use X11 forwarding at work all the time, and it’s very handy. Way better than the old telnet/xhost way.

But why not just use TightVNC?

@Nevyn: “xhost +ServerIP” is dangerous on potentially hostile networks since an IP can be forged. You’re probably having an authentication problem. Check the man page of “xauth”, basically you need to extract the authentication token on the X server (i.e. SSH client) and merge it into the XAuth database on the X client side (i.e. SSH server side).

If you use -XC intead of just -X then the performance would be far better. C is for Compression.

This technique can also be used to serve up Linux applications on a Windows desktop. Brilliant for me – I have the best (and worst) of both worlds.
You need to install an X-server on the windows machine – read: cygwin.
And use something like putty to connect up to the server and run your commands from there.
I’m still having a problem though – I’m still having to run xhost +[Server Address] on my desktop for some strange reason despite all the instructions being followed.

Forget plain old X11 forwarding. Check out NoMachine’s(http://www.nomachine.com/download.php) NX software. It runs over SSH as well but the responsiveness of the NX protocol is unlike any other remote GUI. Don’t be mislead, you can get it all for free if you click the right links on their page =)
