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/

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.

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/
