Problems with ssh and X
First, please accept my apologies for send my message to the wrong list. Thanks to Igor for suggesting the FAQ list. I have now tried: ssh -Y -l username remotemachine I now get the error message: connect 212.159.18.214 port 6000 Connection refused. (the IP address is the static IP address provided by my ISP) There is still nothing in the log of my Netgear NG834G firewall or the ZoneAlarm log. I shutdown Zone alarm and the same thing happened. Any thoughts or suggestions would be gratefully received. Many thanks, Chris.

Which unix you're connecting too? Gentoo does set the DISPLAY variable to the remote ip and breaks X11 Forwarding. bye ago -- [EMAIL PROTECTED] http://www.gotti.org ICQ: 126018723
Re: Problems with ssh and X
Hi Christian, If I recall my past life properly, -Y (X11ForwardingTrusted) does not enable -X (X11Forwarding)... Try this instead: ssh -X -Y -l username remotemachine Also, when you get bored of using command-line options, read 'man ssh_config' G'day, JST On Thu, Dec 16, 2004 at 09:49:49AM +, Dr Christian Hicks wrote: First, please accept my apologies for send my message to the wrong list.

When doing X11Forwarding the DISPLAY variable should point to localhost:10.0 (or higher numbers) or is unset if X11Forwarding does not work. In your case it is set to remotehost:0.0 which is wrong. Find the place where the DISPLAY variable is set and prevent it. bye ago -- [EMAIL PROTECTED] http://www.gotti.org ICQ: 126018723

Problem sorted. Thanks Jean-Sebastien. Chris.

Re: Several problems with ssh and X

It is fine in most aspects, considering that it is free. I have written the following scripts in my .bash_profile to control the initiation of XWin. This is trivial for experts, but perhaps it can help some beginners. if [ ps -a | grep /usr/X11R6/bin/xwin | egrep -v grep /dev/Null ]; then echo X Windows server already started else xwin :0 -multiwindow -nokeyhook -swcursor fi export DISPLAY=127.0.0.1:0.0 xhost + Of course you should modify the options to meet your own need. Now I wish to ask if you have experiences on similar problems of mine. The first thing is that, when I make ssh connections to other machines from the bash shell (instead of say xterm), the Ctrl-C key behaves badly. If I need to press Ctrl-C in some remote program, it simply kills the whole ssh session. In xterm, however, no shuch problem exists. Is there a way to solve this problem? The above is the only part of your message that belongs on the main Cygwin list (see http://cygwin.com/lists.html#available-lists). To be able to use Ctrl-C (and Ctrl-Space, and a couple of other commands) correctly in a cmd window, add tty to $CYGWIN before launching the shell (see http://cygwin.com/cygwin-ug-net/using-cygwinenv.html). The rest of this message belongs on the cygwin-xfree list. I'm redirecting this reply there -- please post X-related follow-ups to that list only. I would have use xterm instead, but I do not know how to change the font size yet, and the characters in xterms are kind of too small on my screen. Try the -fn option, e.g., xterm -fn 10x20. Second, there are some problem with combined keys in some applications. I mean, for example, pressing Alt-F to get the File menu in most applications. In some programs this works fine, but for nedit, the editor I love the best, the Alt-... keys simply do not work. I used XWin32 before (but it is not free) and with some settings the left-Alt key works fine for all programs. I cannot find suggestions on how to setup Cygwin/X to ensure correct behavior of Alt keys, although actually it works for some programs like gftp. Maybe you can help me on this. A WAG: you mentioned ssh in the subject, but it's never come up. Do you have nedit problems when connecting via ssh? Did you read the FAQ: http://x.cygwin.com/docs/faq/cygwin-x-faq.html#q-ssh-no-x11forwarding? If that's not it, perhaps someone else can answer. The third, and maybe not so important problem, is the incompatibility with dual monitor. I have two monitors, and the main monitor is on the right-hand side. The second monitor is smaller than the main monitor. When I start some x programs, they come up in the main monitor. A portion of the window of the program will be empty (on the right-hand side). If I move them to the second monitor, they become normal. I think that's because Cygwin/X only know the size of the main monitor, but it calculates the screen size from the left-most of both monitors. In my case, it happens to be the left-most end of the seond monitor. Therefore, the part of the window that is beyond certain distance from the left-most end of the left monitor are not redrawn, resulting in a blank part in the window. I think this can only be solved in later versions. Try giving the -multiplemonitors option to XWin. Igor That's it. Thank you for the patience reading this. Happy Cygwinning!!
