I just wanted to chip in that I have tried the -r setting without success also (using priviledge separation). I've had success reverting to the previous version of openssh (3.8.1p1-1). OK. Any of you out there that are having this problem up for tracking this down? Even if you can't look at code, there's plenty of tracking that can done before getting to that stage. See: Problem reports: http://cygwin.com/problems.html for initial guidelines. And don't forget that the server has a debug mode too and the output of that is much more telling than that of the client.

SSH on Cygwin Immediate Drops Connections
I'm aware this question has been asked before, but I can't seem to get any solution to work. I'm running an SSHD server through Cygwin. When I attempt to connect to it, it says it connects, and then immediately drops me before I get to the shell. I get the following debug output.

I've done all of these things together, seperately, etc. None of them work. I'm at a complete loss about this. Any help you can provide would be appreciated.
