test of encryption

[Gary Aitken]

In the process of installing 10.3 on former 9.2 system w/ /usr/home
on a separate disk & unchanged.

Having done "xhost +",
I still can't spawn an xterm from a remote machine on the local net:

Xt error: Can't open display: aaa.bbb.ccc.ddd:0.0

Remote account has no .Xauthority;
local account from which X started does.

"This used to work"...
Scratching all body parts, still coming up short.

Hints?
