I've been troubleshooting at omni for a while now. The wifi appears to
work for me, as do the main gateway and the door computer, but various
ethernet-connected devices do not work. I don't know why, but I
suspect the problem is one of the switches is either misconfigured or
malfunctioning, or the maze of ethernet got incorrectly rearranged
somehow in yesterday's withdrawal-induced panic.
I didn't set up these switches, or the connections throughout the
building, the cables are not labelled, and I don't know if the
switches are documented. I'm exhausted and frustrated because I
couldn't figure this out in 2 hours, because things weren't labelled,
and because there's so many people in the building who don't seem to
be here for essential work, and/or who aren't wearing masks or wearing
them improperly.
I'm not even enthusiastic about making the public computers or office
computers work again, because I'm not convinced they are essential
enough to encourage people to sit around and put food service workers
at greater risk.
So I'm going home. Sorry all, someone else will have to figure this out.

The gateway has been replaced with a desktop computer sitting on its
side in the rack on top of the multi-hd storage server. Note that this
is super janky since the two PCI network cards can't be mounted
properly in the somewhat-smaller-than-standard case.
We added two network cards and were planning to use the built-in card
as well, but currently the built-in card is not used and the private
network is down. There are two reasons:
* The switch used for the private network had one of its fans die and
I turned it off until we can replace the fan so it won't overheat
* The built-in network card appears to need firmware which I'm not
going to bother with until the fan on the private network switch is
replaced
Also, we might get a new server rather than using this old desktop machine.
The new computer is using the old harddrive. I changed the following
files due to the different names of the network interfaces:
/etc/network/interfaces
/etc/default/isc-dhcp-server
/etc/iptables/rules.v4
/etc/iptables/rules.v6
You can find backups of the files from before my changes at the same
paths with .old added (for the parent dir for /etc/iptables)
