Fore the record -- I had the exact same problem with a 4.0-RELEASE box I have on which I set up OpenSSH. Both a variety of ssh clients and the OpenSSH server configured to allow X forwarding and couldn't get it to actually forward X connections. Got a wierd protocol authentication error that I dont recall off hand. Note that it seemed to be latency related because when I tried from a box on the same local lan, it worked almost all of the time, but when I tried over an ISDN link through a couple of slow routers, etc it never worked. I found the exact same error message somewhere in the archives at openssh.org or .net or wherever the web site is, but no resolution, and then I found someone else complaining about it in one of the bsd usenet newsgroups, but he never replied to my querries. So, I did the logical thing and went back to non-OpenSSH server and haven't had any problems. Let us all know if you figure out anything -- kind of frustrating -- I burned several hours of time trying to track this down with no luck.
