[kwlug-disc] Adventures in hacking

I have seen cases where the built in Ethernet would not come
up on its own, for an unknown reason.

It will show up in lshw -c net, but would be disabled.

So I resorted to the snippet below in /etc/network/interfaces
with a comment so I don't forget.

(Yes, I never bothered with netplan either)

The two boards I have seen doing this were Gigabyte
F2A88X-D3H (Ethernet was called enp1s0) and the MSI
X570-A Pro (enp39s0)

# IMPORTNAT: This interface MUST be static. It cannot be DHCP !!
# If it is DHCP, then weewx weather station will not start
# DO NOT CHANGE THIS!!!
auto enp39s0
iface enp39s0 inet static
  address           192.168.0.x
  gateway           192.168.0.1
  netmask           255.255.255.0
  broadcast         192.168.0.255
  dns-nameservers   192.168.0.1
