I'm trying to get X11 port forwarding over SSH to work. This will hopefully ultimately enable me to connect to the linux box from home and export the display onto my windows box at home (xclock, xterm, etc)

I have reviewed the "Similar threads" before posting an didnt see anything, in addition i've been googling for 2+ hours now.

I have both x-Win32 and cygwin-x on my system. I need to get this working with X-Win32 as we have a consultant using that x-windows server.

I've already modified my sshd_config file and rebooted my system. New config file reads:

X11Forwarding yes
X11DisplayOffset 10

I've tried adding the "X11UseLocalhost yes" setting, but it is not recognized by the sshd service.

Needless to say that no matter what i do, i get an event log message (using putty to connect) saying that:

"X11 forwarding refused"

then later i get a message "Server unexpectedly closed network connection" and i am unable to interact in putty.

Now if i change the setting "X11Forwarding yes" to "X11Forwarding no" then i will still get the message:

"X11 forwarding refused"

but i dont get the "Server unexpectedly closed network connection" message and i am still able to interact with the system via putty.

I'm definately stumped on this one. Any help would be greatly appreciated.

You don't have to change any of the configurations. Give this command to use X forwarding with ssh.

Also make sure you have X installed in cygwin, and any other graphics libraries that might be needed. If you are trying to forward apps that run in gnome, then install gnome in cygwin, so that you get the graphics libraries needed. If you are using the Openssh server for Windows from this website http://sshwindows.sourceforge.net/, that won't work because it installs the minimal cygwin software needed to get ssh working and is not enough to forward X.

ok, i tried what you asked (ssh -X -I username@hostname) and i still see the connection coming back from the server to port 6000 on my system. X-Win32 sits on port 6000 and waits for incoming connections. X-Win32 is my x-windows server that is installed on my system.

If i type simply "ssh username@hostname" (note NO port forwarding) it all behaves the same way. My remote solaris server will connect back to my box on port 6000. I need that communication to come back through the ssh tunnel.

Fakie_flip, thanks for the advise, i already had cygwin-x installed on my system. I also have X-Win32 which does the same thing.

Overall i cannot use the ssh command as my remote technitian does not have cygwin installed on his system. It conflicts with other applications installed. He uses putty to SSH into the solaris box. He also bought X-Win32 to use as his x-windows server.

So, in the end i need this to work with putty and X-Win32. If that is impossible then i need to find a way to simply get X11 port forwarding to work. So all of my X11 communications come through the ssh tunnel.

Thanks for the ideas and help so far.

Well, i got it working now. The problem was with my SSH server installed on the solaris box. I applied a patch cluster, and X11 port forwarding works now! Oh and i've added the line:

X11UseLocalhost yes line to the sshd_config file. sshd will start up with that option in the config file.

good, im glad you figured it out

I am running sunos 5.10 and am having the same problem.
I've got this
# X11 tunneling options
X11Forwarding yes
X11DisplayOffset 10
X11UseLocalhost yes

in my sshd config but putty says
X11 forwarding refused

and there's nothing on the server side to say why.
What patch did you apply? Or what else might you have done to get that working?

You can't have all the features of Linux/GNU SSH w/Putty. If you want X forwarding w/SSH, use Linux instead of Winblows.

Or install an X11 server on your Windows box, like the one bundled with cygwin ( http://xfree.cygwin.com/ )
Or use an O/S that support X11 natively, like *BSDs, Solaris, macOS X, etc ... and Gnu/Linux obviously

It's best to use Linux instead of Winblows.

What is the best solution for you isn't necessarily the best for someone else.
The question was about SSH X forwarding from Windows to Solaris, not about what is the best O/S to use as a SSH client.

You first gave a wrong answer: "You can't have all the features of Linux/GNU SSH w/Putty." Putty support X11 forwarding, it has a checkbox to enable it.

Then you give an unhelpful opinion.

You don't ever shut up do you? I have a life outside of LQ at college and with over 4000 posts, I can see you do not even though you may be definsive about that. I'm not going to reply to your posts anymore. I'll be the mature one and be the first one to stop replying to ignorance.

You'd rather stop giving innacurate / misleading / childish / offensive answers to people posting in this forum.

Man, these forums have really gone down. Everybody knows jlliagre is the most helpful guy around on Solaris. Give him a break.

It would be nice if people could just focus on the issues instead of jumping all over each other.

(However in principle I agree that it's a good suggestion to not ever use winbloze for anything )

How much do I have to pay to get out of these forums?

So do I by the way
