I set up an ssh server on a fresh windows 7 machine using the latest version of cygwin. Disabled the firewall.

I can ssh into it from itself, from a different windows box (using winssh), and from a linux vm. In spite of that, I tried to ssh in from two different macs, and neither would let me!

This is the debug output:

OpenSSH_5.1p1, OpenSSL 0.9.7l 28 Sep 2006

It shows the same output, and fails at the same place, whether I have put my public key on the ssh server or not.

Any help would be appreciated-- hopefully someone has run into this before?

I remember running into this issue. Since MacOS X is really BSD, it has additional security features. Make sure that your $USER directory is, and your $USER/.ssd is set so that only your user (not group or world) have read permissions to your files.

I was hopeful, but I changed the permissions on both on the files within .ssh (to u+rw) and on the folders you mentioned (to u+rwx), with no luck. –  Denise Jun 17 '10 at 13:22
