- Subject: Unable to log in to SSH Server using Cygwin
I've been trying to set up an SSH server in Cygwin and I haven't been
able to successfully log in to the localhost. Following some online
tutorials, I have set up a public/private key pair, ran
ssh-host-config and then when attempting to log in, I get the below
$ ssh -v -i ~/.ssh/id_dsa [user]@[hostname]
OpenSSH_6.1p1, OpenSSL 1.0.1c 10 May 2012

Connection closed by [host ip]
It seems that as soon as it tries to authenticate the private key, I
get the "Connection closed" message. Has anyone experienced this and
is aware of a solution?
I'm running Cygwin 1.7.17 on Windows Server 2003. My Windows user
account has administrative privileges.
I've tried running ssh into this box from my local Windows PC and am
actually able to use password authentication. However, I have a
requirement that I muse use public key authentication. This at least
tells me there shouldn't be any firewall issue.
Any help in this matter would be appreciated.
