FC 2 includes OpenSSH_3.6.1p2, SSH protocols 1.5/2.0, OpenSSL 0x0090701f
Debian Sarge includes OpenSSH_3.8.1p1 Debian-8.sarge.4, OpenSSL 0.9.7e
25 Oct 2004

Debian also includes at least one other SSH implementation. I played
with it briefly, but encountered some problems (don't remember what they
were) and due to lack of time returned to OpenSSH.

If the version numbers are really totally different, the other SSH
probably isn't OpenSSH. As you can see above, OpenSSH on Sarge is a bit
newer, but not much.

I'm not sure if SSH existed in 1994 (I certainly learned about it a few
years later). OpenSSH as the first major branch is certainly not that
old. There are other branches, and at least two complete
reimplementations.

I think is is more likely that you have disallowed X forwarding on the
SSH server(s). I certainly can connect with both ssh -X and ssh -Y from a
debian box to a FC2 box (even though FC2 openssh is too old to recognize
-Y) and connect with ssh -X from FC2 to debian.

Check the documentation and configuration of the ssh servers. Use the
option -vv to get (lots of) debug output.
