Re: How to remotly launch application with SSH and Cygwin/X server
I have similar problem with Cygwin 1.7.1's SSHD. I'm unable to start any Windows GUI program via SSH. Strange is the problem doesn't occur in SSHD shipped with cygwin 1.5.25-7, which I had installed yesterday. In version 1.5 enough thing to do was enable service option: Allow interact with desktop, then GUI applications were able to be correctly run via ssh. In version 1.7 switch on this option in Cygwin SSHD service option doesn't help. Application cannot draw himself, and generates tons of denial access errors. I tried also grant acces in Local Policies to user, Generate security audits Replace process level token Create process token didn't help too :( I have Win XP SP2, under this system I had installed Cygwin 1.5 and launch GUI apps via ssh worked. Now I have Win XP SP2 too, but current Cygwin version is 1.7.1 - It doesn't work. I tried to find answer to this problem, and I saw this problem is not a new one (people complains since A.D. ~2006), but nobody could definitly answer how to make it work, or at least say that is impossible to do at all. If someone has some info, please help. Thanks.

Yes. I'll try to explain better: I'm log on to windows as e.g. User1, that
is administrator user. When I start cygwin shell I can simply run:
$notepad
I see Notepad application correct launched, but If I do it this way:
$ssh us...@localhost
us...@localhost's password:
Last login: Fri Feb 26 18:00:01 2010 from localhost
us...@athlon ~
$ notepad
I have notepad launched (I see it on process ) but it cannot draw correctly
himself on the screen. The same behaviour was in Cygwin 1.5, but then
sufficient thing to do was simply select SSHD service option: Allow service
to interact with desktop, which was solve the problem.
With Cygwins' 1.7 SSHD, selection this option does not take any effect, I
have still this unexpected to me behaviour.
From application point of view it is somekind still permission problem
(exactly the same as was in cygwin 1.5 before switch on Allow service to
interact with desktop option), for example:
int main(int argc, char* argv[])
{
int retVal = 0;
retVal = SetCursorPos(0, 0);
if (retVal == 0)
{
std::cout SetCursorPos error [
GetLastError() ].
std::endl;
//
// GetLastError() returns 5 - ACCESS VIOLATION
// when it is run via ssh in Cygwin 1.7.1.
//
}
return 0;
}
Additional info:
SSHD process user name is SYSTEM
process launched via ssh user name is User1, but it still has no access to
the desktop.

Re: How to remotly launch application with SSH and Cygwin/X server
Ok thanks for your information Larry. When I enable Allow service to interact with desktop, If I launch from X a ssh command to Y with firefox it launches the Firefox window now but not in its normal form. We have the Firebox taskbar entry with the border of the application, but not the main tab. I tried with Internet Explorer and I've got the same behavior, only the taskbar entry and the border not the main page. It seems like a display bug or something else (I tried these tests on 2 different PCs and same effects...) Do you know what can cause this ? Here my test environments : Windows XP SP3 Windows Vista SP2 IE 6.0.2900 Firefox 3.5.6 I would like to share my experience with other tools : Winexe : Works well between Linux and Windows XP in interactive mode. Works on Vista but the interactive mode is not present which is prejudicial for my context. PsExec : works well but it runs only on Windows unfortunately. If you have some advices, I'm looking forward to hearing from you. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/

Is there a mean of displaying Firefox launched from the Linux box on Windows ? Generally, no. Depending on the version of Windows and Cygwin you're running, you can go to the Control Panel-Administrative Tools-Services-Cygwin SSHD- Log On and enable Allow service to interact with desktop if you're already running the service with Local System. Pretty much for any other case, you can't do on Windows what you want to do. -- Larry Hall http://www.rfk.com RFK Partners, Inc. (508) 893-9779 - RFK Office 216 Dalton Rd.
