Hello,

I'm trying to run xfig, but the version on this Fedora laptop is jacked.

So, I installed xfig on one of the FreeBSD servers, to forward over SSH,
with ssh -X, right?  I can ssh -X and run X apps on other Linux hosts.
But here I have a problem:

 10:10 djh@cobra ~$ ssh -X -i ~/.ssh/mito.key castor

FreeBSD 5.3-RELEASE (GENERIC) #0: Fri Nov  5 04:19:18 UTC 2004

0-10:11 djh@castor ~> xfig
Error: Can't open display: 

Huh!  I've dug through my .tcshrc, my .login ... nothing is clobbering
any DISPLAY variables.

SSH_CLIENT=192.168.1.128 34586 22
SSH_CONNECTION=192.168.1.128 34586 192.168.1.28 22
SSH_TTY=/dev/ttyp2

Let's see ... I went through sshd_config, but it appears that by
default:
#X11Forwarding yes
#X11DisplayOffset 10
#X11UseLocalhost yes

I ... have no idea ... anyone run into this before?

I'll try uncommenting the defauilt options, just in case sshd got
configured funny, but ... dunno ...

Thanks,
-danny
