Where would I tell it to skip the IPV6 stuffs? AFAIK, there are no ipv6
things enabled, and my little 8 port switch does not to my knowledge
even know what ipv6 is. And ALL paths go thru that switch.

I just moved my known_hosts to known_hosts.old, then reaccepted the keys
from both machines. Still no luck.

LinuxCNC terminated with an error. You can find more information in the

/home/gene/linuxcnc_debug.txt
and
/home/gene/linuxcnc_print.txt
as well as in the output of the shell command 'dmesg' and in the terminal
None of which looks at all informative.
However, the known_hosts file pair are exactly the same size. It looks
like, for a login and key add for 2 machines, that there is 4 keys in
the file. Here it is, inserted.
