Okay, so far, so good.

Okay, the ssh logins are working correctly. Now we have a Linuxcnc
problem. Just to verify the ssh logins are working correctly, can you
bring up any other X applications, like gears, or the eyes?

Okay, this kinda goes back to the same error as above - the "BACKGROUND ."
It keeps trying to invoke the 'image" command on something which doesn't
exist. Here's one workaround I found:
"Workaround:
Create ~/.Xresources plain text file with content:
*.background: gray75
then
$xrdb -load ~/.Xresources"
This may not set up the right color for the "BACKGROUND", but try it to see
if the errors go away.

That's normal for the keys to have two of each for each machine.
