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?
