How to run X Session from RH8 via ssh -X? How to run vnc via ssh?
Thanks for all the help so far. I hope this will be a 100% cygwin-mailing-list compliant posting. (1) I read the description of TOFU and I still don't understand it. I don't understand what I am doing wrong. If I want to quote a previous posting, should I not put the quoted text first and then my response? (2) For reasons I don't understand, there was a conflict between my router's sshd and my cygwin's sshd so I resolved the problem by changing the cygwin's configuration file to start sshd on a different port. Now, using a Red Hat 8 client, I can use both rdesktop and ssh to create two different simultaneous sessions on my win2003 server. However, I cannot seem to start an X session from my ssh -X -p 892 [EMAIL PROTECTED] session. I tried running explorer . and that just hung. OK, that was not an X program. Then I tried /usr/X11R6/bin/xclock and it said it could not open the display. Having already done a xhost+ remote wan address before running ssh I tried export DISPLAY=client lan address:0.0 but that did not help: it still could not open the display. Do I need to punch a whole in my client's firewall? I doubt the will let me do that. Don't I need to start the xserver? Here is my attempt: startxwin.bat - Starting on Windows NT/2000/XP/2003^M Welcome to the XWin X Server Vendor: The Cygwin/X Project Release: 6.8.2.0-4 Contact: cygwin-xfree@cygwin.com XWin was started with the following command line: /usr/X11R6/bin/XWin -multiwindow -clipboard -silent-dup-error _XSERVTransmkdir: Cannot create /tmp/.X11-unix with root ownership winValidateArgs - g_iNumScreens: 1 iMaxConsecutiveScreen: 1 winCheckDisplayNumber - Cygwin/X is already running on display 0 Fatal server error: InitOutput - Duplicate invocation on display number: 0. Exiting. winDeinitMultiWindowWM - Noting shutdown in progress (3) What about vnc? I have installed RealVNC on both the RH8 client and the Windows 2003 server. Is there also a cygwin VNC? I don't remember seeing one. Can I make vnc tunnel thru ssh? Would I use the -L or the -R qualifier on ssh? What would that look like?

It's not what you /did/ do here:- http://www.cygwin.com/ml/cygwin/2006-03/msg00055.html where you put your reply at the top and then quoted the /entire/ previous post beneath it without snipping the unnecessary quotation, and that's what TOFU means: TOp-posted reply with FUll quotation underneath. cheers, DaveK -- Can't think of a witty .sigline today -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

snip However, I cannot seem to start an X session from my ssh -X -p 892 [EMAIL PROTECTED] session. snip I have previously reported this behavior, and not seen a fix, it used to work. The problem is running xauth under the covers hangs. If you add -v -v -v to your line above, you'll see it hang like: debug2: x11_get_proto: /usr/X11R6/bin/xauth -f /tmp/ssh-c96kVgf686/xauthfile generate 127.0.0.1:0.0 MIT-MAGIC-COOKIE-1 untrusted timeout 1200 2/dev/null If you remove the X forwarding switch (i.e., not use -X) you should be able to login. If you kill the X server and/or kill the hung xauth process, an 'empty' ssh Window (non-X) will appear, indicating to me that for some reason, xauth is looking for input from the console vs. stdin. As a work around, you can manually reverse forward the display, something like: ssh -R 6001:localhost:6000 [EMAIL PROTECTED] then manually setting your display, in the above case: export DISPLAY=:1 Manually picking a port as above can interfere or fail if it is already in use, using the -X (or -Y) enlists the sshd on the target to find a free port.

What makes you think so? Maybe it's trying to generate some standard output, since that line only redirects stderr. Maybe it's the server not sending a reply, and it's not hung, nor waiting for input, just waiting for the timeout to occur - 1200 seconds is twenty minutes, are you sure you waited that long? cheers, DaveK -- Can't think of a witty .sigline today -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
