Because its not working? :)

I recall I did have to use xauth at one time, years ago.  Unforch, no man 
pages for it are installed, and the --help output is criminally concise.

If I do an 'xauth list', it only spits out one cookie, for the wap11 at 
*.*.*.100 on my local network.

X11UseLocalHost is
#X11UseLocalhost yes in /etc/ssh/sshd_config
commented out.  Does changing that need a reboot?

Thanks Glynn.
