I have (finally) got
sshd working under cygwin on Win7 - well, sort of.
The
sshd runs as user 'cyg_server'. I'm able to successfully ssh to my computer using that same user name.
However, if I attempt to ssh using my normal (Windows) user name, it fails trying to allocate a pty for my login session. For example, output of '
sshd -D -d -d -d' contains this ..
...

Currently /dev is owned by my normal account. I've tried changing its ownership to cyg_server as well as SYSTEM. In both cases the problem persists. I've also changed permissions for /dev (e.g, 700 and 777) - again problem persists.
[As a side note - it is strange that whenever I do 'ls -al /dev' the ptys do not show up. However, if I 'ls -l /dev/ptyX' for a pty I know to exist, it shows up. Is that normal for cygwin?]
