Re: Tunneling does not seem to work here (newbie)?

Well, I also have problems with this, and although it is probably not a bug
report, I was unable to resolve the following two issues by reading  
documentation.

1. Sometime ago, in some old version of cygwin  (I apologise for not 
being able to
tell you which one exactly) I was able to display a window from another 
machine
by doing ssh and then setting the DISPLAY variable to point to the 
cygwin box
(before that the remote host was added to the list of allowed hosts). 
Now with the
latest version this does not work (I get an error message "Xlib: no 
protocol specified"),
only ssh -Y does. But this results in much slower performance, and 
therefore the
question is: was it an intentinal change or there is some new step that 
I am supposed
to do now to be able to just point to my cygwin box?

2. Now, when I try to run sshd on the cygwin box (and I set up the ssh 
server
according to the README file) I am able to check that the server works 
by logging
in from the bash prompt where I am already logged on, but not from any 
remote
host, or even from the same prompt but logged on as another user. Before 
upgrading
to the most recent version everything worked just fine.

These problems I have on both WinXP and Win2K, with or without ZoneAlarm
5 or 4.5.

Any suggestions?

Thanks,
Boris.
