RE: Connection closed on localhost (windows 2000 Pro)

Ed,

I followed your instructions and it worked! Thanks for resolving this. One
question about setting the password on the service. The account that shows
for my service is Local System? Is that the one on your system(s)?

John

I was having the same issue on 2 different boxes in that as soon as I would
authenticate it would close the connection. 1 was Win2000 and the other was
WINXP both professional editions. Here is what I found: 1st when you install
CYGWIN it creates a new user in user admin for 2000 you have to enable this
account from admin tools then set a password on it. Next go to services and
set the same password on the CYGWIN sshd service. 2nd I went back to the
CYGWIN install directory and re-ran CYGWIN Setup.exe when you get to the
packages in the upper right hand corner click on view then scroll down to
openssh then click on it until it goes back to the 3.8.1p1 version and
finish the install. Evidentally there is a bug in 3.9 that will not work on
2000 or XP. By the way I have both Windows OS' with all the critical updates
not sure if it matters or not. Good Luck.

Carl,

Thanks for your advice. I have not found a good howto to help setup, the one
you refer to had the most detailed steps I've seen so far. I did have
uninstall and reinstall several times before I could get by windows errors
(1032, 1067), I was not removing the service correctly. I'm not sure if I
have any correct SSH keys generated. Here is the ssh localhost with the v
options you suggested.

Sounds like the problem I have. (so no answers here, but perhaps some help
debugging.)

Something I am still wondering about: What does sshd look for in
/etc/passwd?

I did just figure out how this:
$ /usr/sbin/sshd -d -d -d

and then in a 2nd shell: $ ssh -v -v -v localhost

You get lots to look at.

But, on my end I am back to not being able to authenticate - I get "Access
Denied" for everything.

Did you find a good HowTo for setting this up? (I found 2 or 3 which I
could only follow so far, till I get to "Start the service from the control
panel. " and I get "error: 1067 process terminated unexpectedly"

http://ist.uwaterloo.ca/~kscully/cygwin/CygwinSSHd_win2k.html

When running from the command prompt, I had to subst m: c:\cygwin so that
\etc was off the root.
