Hi everyone
I have a strange problem with sshd and can't seem to find any tips in
the mailing list archives, ssh docs, or on the web.
I have been getting the following error, "ssh_exchange_identification:
Connection closed by remote host" - see (1) below
When I run a verbose ssh, I get the output shown in (2) below. I have
attached the cygcheck output below as (3).
This computer was set up just a few weeks ago following a rebuild. I
downloaded fresh cygwin from the internet as shown in (3). Recently I
wanted to add an account for a friend, so I did the following:
(a) added a new user account.
(b) from my usual account, ran *mkpasswd -l > /etc/passwd*
(c) from my usual account, ran *mkgroup -l > /etc/group
*(d) added two DNS entries for my (static) IP address using www.dyndns.org
It was at this point that I noticed that ssh wasn't working at all, not
even from localhost. I tried to reinstall ssh using the cygwin setup. I
deleted my /etc/ssh* files and my .ssh directory to try to eliminate any
hangover.
I have read that reverse DNS lookups can cause problems, also that there
have been recent changes to the ssh config stuff in cygwin (but am not
an expert on either). Could either of these issues be bugs which are
causing me problems here?
I had a look for /etc/hosts.allow and /etc/hosts.deny files under
cygwin, and these files don't exist.
Any suggestions mightily appreciated!

Overwrite existing /etc/sshd_config file? (yes/no) yes
Privilege separation is set to yes by default since OpenSSH 3.3.
However, this requires a non-privileged account called 'sshd'.
For more info on privilege separation read
/usr/share/doc/openssh/README.privsep.
Should privilege separation be used? (yes/no) yes

Host configuration finished. Have fun!
