Cygwin SSH problem, unable to connect to local host, connection closed by 127.0.0.1

I have installed cygwin on a windows 2003 server, I added the openssh package, set up the neccesary enviroment variables, run the following commands

mkpasswd -l > /etc/passwd
mkgroup  -l > /etc/group
ssh-host-config
ssh-user-config

I've started the SSH service but when i 开发者_如何学Pythonrun ssh -v localhost i get the following

can anyone advise what i need to do to get it working?

If you really need elevated privileges start cygwin shell with from an account with administrative privileges (XP) or r-click on cygwin.bat and "run as administrator" (Vista,Win7). That should olve this issue.

This looks like the same issue I saw on this post, Public key authentication issues on cygwin.

You can verify by going into the next verbosity level when connecting,

# ssh -vv localhost

When you installed Cygwin and ran ssh-host-config, you might have created user called "cyg_server". So when you are connecting to ssh, you need to use that user "cyg_server@localhost".

When you run ssh with that user, it will ask you for the password that you provided when you ran ssh-host-config.

$ ssh cyg_server@localhost
cyg_server@localhost's password:
Last login: Mon Dec 31 01:14:44 2012 from ::1
cyg_server@polorumpus ~
$
I hope it will be useful.
