I saw one other post that said that you should 
make sure CYGWIN is set to "ntsec" but that doesn't 
necessarily mean that chmod or chown is going to work. 

I tried your example from a bash shell on my system, 
with CYGWIN=binmode tty ntsec. Of course, chmod didn't 
work right. You can see from the following output that 
chmod worked in some cases, and chown definitely 
didn't work. I checked the FAQ, the archives, and the 
documentation, but there seem to only be suggestions 
to "set CYGWIN=ntsec" and "you can't use chmod on 95/98". 

This seems like the root of your SSH problem Dave, I just
wish I knew why chmod didn't work.

Your mouse has moved.
Windows NT must be restarted for the change to take effect.
Reboot now?  [OK]
