*UPDATE THIS RIGHT NOW*. Again, old security problems.

Again, you need some updates. There have been subtle changes in both
releases. And read the manual pages on all of these systems on sshd and its
options which may be set to restrict things in ways that you are seeing
here.

No surprise, that's in sshd_config and is probably disabled.

Update. It's pretty easy to do, and will make your life considerably.
Updating to OpenSSH will also, I think, be more secure and mean you only
have to have one daemon installed, not one for SSH1 and another for SSH2
that summons the SSH1 daemon as needed....
