[lug] Ubuntu 18.04 Route Metric

[Bear Giles]

I'm fine now. The USB wifi let me begin configuring the system before the
10 Gbps NICs worked, and I could use a desktop (with its own NIC) as a
gateway.

It was just a really strange feeling since I normally buy used stuff that's
several generations old and then upgrade the stuff that can be upgraded.
It's very strange to be in a position where my hardware is too new.

...

It's a good Learning Experience. A lot of people have a set of "must have"
USB sticks, e.g., something with memtest86, an Ubuntu startup disk (which
can be used as temporary system), tails, etc.This experience calls out that
the kit should also have a USB wifi dongle. Probably a bluetooth
transceiver as well, although that may be a chicken-and-egg situation if
you need to use that bluetooth dongle to the keyboard and mouse to work.

A fun thing to consider for the kit? A raspberry pi and powercell battery
that can run it for an hour. You can have it set up so it can connect to
either wifi or tether to your phone while the RJ-45 NIC can run a DHCP
server and  act as a gateway. You're golden if the system has a RJ-45 NIC
(you do have a cat 5 or better cable in your kit, right?). You could even
handle thin laptops by adding a second wifi device to your rpi - either on
a 'hat' or a USB dongle.

(I don't think a wifi device can be on multiple SSIDs. Multiple IP
addresses? Sure. But not multiple SSIDs. However maybe it's possible with
the correct settings.)

If you want to be really fancy you could even set up a BOOTP server so you
could configure the system's BIOS to boot from an image on the RPi.

The RPi solves a slightly different problem but I could see it being really
useful in some environments. The main limitation would be getting access to
the NIC port.
