RE: Remote open X application
OK, with Harold's help, it now works for me at last. By default, you should not need to set the DISPLAY variable, the sshd X11 tunnelling configuration should take care of this. But because some admin is not familiar with this, you may need to set up manually. Then I set it to be: localhost:10.1 and it works. But according to Harold, if somebody else is logged on via ssh already and using 10.0, I should set it be to 11.1, but I cannot know that. Anyway, this is a problem with the Remote Linux machine's sshd X11 tunnelling configuration. -Original Message- From: Harold L Hunt II [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 17, 2003 9:17 PM To: Welson Sun Subject: Re: Remote open X application Welson, Let's keep this discussion on the mailing list for others to see.

So I think this maybe a problem with the Linux sshd configuration. You are not supposed to do that. ssh works by redirecting your X apps to point to a local screen that sshd is listening on. If the DISPLAY variable is unset when you login to the remote machine, then it means that the remote machine is not properly configured for ssh X tunnelling. If it is set, then leave it alone and try running an app... it should work fine. That is what I meant when I said to follow the instructions on the web page; I didn't leave out any steps, which means that I don't want you to add any steps that I didn't mention. Please try that and report your results to the list. > BTW, what IRC program do you recommend? I use Mozilla's IRC program called Chatzilla. Harold

Follow the instructions on the following page for ssh, very carefully: http://xfree86.cygwin.com/docs/ug/using-remote-apps.html You should not have any trouble if you do it this way... unless your Linux machines need to have their sshd configuration changed, which you can find documentation about elsewhere.

OK, I know what's wrong now. The step should be: 1. Start Cygwin X 2. xhost + Remote Server 3. ssh -X Remote Server This works for me now. At least the "refused by server" is resolved. But not all Linux machines I can start X applications on some Linux machine in this way, but on some others, it still complains about: Error: Cann't open display: localhost:0.0 I have no idea, now the problem looks like is relating with the Linux machine setup.

Re: can't use windows with GoBack?
Just my late WAG: Try setting your display variable to localhost:0.0 and using -nolisten local. That should avoid some possible file system interaction.
