I am trying to setup ssh and ssh to localhost on Cygwin, but I am getting the following error. Any suggestions will be appreciated:

Can you paste the output of auth.log when you try to login, it will be there on all ubuntu machines. tailf /var/log/auth.log –  ZVIK Aug 8 '12 at 7:09
    
its not present. I am doing this on Cygwin. Had missed out on putting this bit of information; have updated the question. under var/log/ , I only have these files: lastlog setup.log setup.log.full sshd.log –  fixxxer Aug 8 '12 at 7:24
    
It's the logs on the server you'll want to look at. Start sshd in debug mode if you can't find anything already logged in your system logs. –  Michael Hampton Aug 8 '12 at 7:24
    
added the last paragraph in the question. Does it help ? –  fixxxer Aug 8 '12 at 8:20

The permissions on /var/empty aren't correct.

Try this:

 chown root:root /var/empty
 chmod 755 /var/empty
 chmod 711 /var/empty/sshd
