And this disclosed that I had not properly added coyote.coyote.den to
the /etc/hosts file on that machine. That mistake, fixed, now makes the
local net pingable. The rest of it, whats powered up, was/is all
pingable. It just wasn't tried. This machine is generally the master,
and when I couldn't ping it, I assumed none of the local stuff worked.
Checking that on some of my other machines disclosed that something
besides me is mucking with the /etc/hosts on some, but not all, of the
other machines. And its something I'll have to fix from the machines own
keyboard because my /sshnet/localname network doesn't allow root logins.
The /etc/hosts file on go704 has been stripped to just itself! Fixed and
chattr +i added to it now.
So, I've some repair work to do, and some sudo chattr +i's to apply to
/etc/hosts. The real question is who, besides me as sudo, has rights to
edit /etc/hosts?
For what you show bpi54 is the short hostname so you need to do
ping -c1 bpi54
which worked
and not
ping -c1 coyote
which didn't because it was missing from the hosts file!
And I'm pretty sure I put it in there correctly when I installed armbian
on it.
I'll own the mistake, my apologies to all. I thank you for the impetus
to check, assuming it was as I put it when installing the machine.
Take care and stay well all.

Cheers, Gene Heskett.
