ssh X11 forwarding not working on FreeBSD 6.2 (SOLVED)

[Terry Todd]

The cause of this problem, 

$ xhost
Xlib: connection to "localhost:10.0" refused by server
Xlib: PuTTY X11 proxy: wrong authentication protocol attempted
xhost:  unable to open display "localhost:10.0"

was that the hostname on the FreeBSD system was blank.  Once I set
the hostname it works fine.  In fact you don't even need to turn
on any of the options in the sshd_config or ssh_config files.

Who woulda thunk it.  I figured it out by trying it on 2 other
FreeBSD systems that did work and comparing how they worked to the
one that didn't.

Try it on your systems and I'll bet you see the same thing.
