XAuthLocation (Re: x11

[Makoto Fujiwara <makoto%ki.nu@localhost>]

Add -v option to ssh command, say,
ssh -v -Y hostname

And watch Xauth related lines.
Bad news if
  Warning: No xauth data; using fake authentication data for X11 forwarding.

modular-xorg provides
   /usr/pkg/bin/xauth
while native X provides
   /usr/X11R7/bin/xauth

And check the line in your ~/.ssh/config like:
## XAuthLocation /usr/pkg/bin/xauth
and  also the same thing in /etc/ssh/sshd_config 

You may type
ssh -v -o XauthLocation=/usr/pkg/bin/xauth -Y hostname
 or
ssh -v -o XauthLocation=/usr/X11R7/bin/xauth -Y hostname
