Same shell on this machine. login to shop works, to lathe doesn't. If its 
the login shell on the second machine, how do I set that?  And why should 
it be different since the install cd was the exact same cd?

I had to completely blacklist/disable ipv6 on the machine the XForward 
isn't working on.

Contains, apparently by default:

X11Forwarding yes
X11DisplayOffset 10>

I was pointed at the xauth command to fix this, but that man page has to 
rank near the top for all time obtuseness, and when executed on the non-
working machine, returns:

gene at lathe:~$ pwd
/home/gene
gene at lathe:~$ xauth list
xauth:  creating new authority file /home/gene/.Xauthority
gene at lathe:~$ cat .Xauthority
cat: .Xauthority: No such file or directory

for as many times as you want to hit the up-arrow & return.

Any better ideas?

Thanks all.

Cheers, Gene
