Did something happen to the omni door computer? I can't reach it over
the network, even from within the building. It appears to be working,
letting people in. I tried looking at the box, but couldn't make sense
of the mess of cables. Maybe an ethernet got disconnected somewhere?
The rest of the network is fine. Other devices on that subnet and that
interface are reachable, but:
$ ip neigh | grep 100.64.64.11
100.64.64.11 dev enp3s2 FAILED

New subject: [omni-discuss] can't reach door computer
the beaglebone (BB) & switch to BB were sending (green lights on eth ports)
but the BB wasn't receiving (orange light...) so i rebooted the BB & it's
pinging now

[ removing omni-discuss and adding access control list in addition to two other
"admin" lists i didn't know about ]
this is something that has happened before. Something about the beaglebone
periodically randomly disables the ethernet port until it gets restarted. We
have never logged into the beaglebone (through its TTL serial port console for
example) in order to diagnose why, we just power cycle it and it comes back up.
would be interesting to save logs to a microSD card (we keep the built-in eMMC
in read-only mode most of the time to prevent wear) so that we could get a clue
as to what's happeneing. Or perhaps make a process to watch for the ethernet
port being powered down and restart it if that happens for whatever reason.

as it appears to be a hardware issue with beaglebone blacks, prolly need a
rpi if you want to avoid reboots

So I looked at the bash script Robb found, and it turns out it's specific to an
issue of the Beaglebone booting up without ethernet working in the first place.
It does not refer to ethernet stopping working while running! So that implies
that either our beaglebone is already rebooting but the ethernet doesn't come up
(in which case this script would be wise) OR we're experiencing something else
entirely, and that script wouldn't help us.
I just checked and saw we're running / off of the built-in eMMC chip (4gb) and
I uncommented the line of /etc/fstab that causes the (8gb) microSD card to be
mounted automatically to /mnt/sd_card/ (after fixing the parameters)
So we can do logging to /mnt/sd_card/ and use it for backup purposes and
logging, because it's a removable microSD card and we don't have to worry about
ruining it. And we should log there, so that if the ethernet port goes down we
will have a record of why that happened - assuming someone knows how to
configure it so that cached disk writes are flushed to the disk every few
minutes so that when we have to power cycle it, the logs are actually written
to disk by then.

fwiw, the building lost all mains power a day or two ago which may have
caused it to reboot w/o eth. regardless, Jake's solution seems like the
easiest solution

mine is not a solution! just a method of increasing our awareness of the
situation.
Robb it sounds like your link might be appropriate for our situation after all
but I always like to have more information before trying a particular solution.
Does anyone know how to turn on logging and direct the logs to the appropriate
place? and cause periodic filesystem flush?
