Bridge to the Shop

I tried out a 64bit Gentoo image for Raspberry Pi...    This is very Gentoo.  The Rapberry Pi 3B+ has a 64bit processor, but 32 interface to, like, everything.  Basicially no one runs a 64bit OS on the Raspberry Pi, but you could, and if you use Gentoo and you can do something, well why not?!

It ran very fast for a couple of minutes, then it crashed.

I went back to Raspbian, and ran into a problem.  One of my Raspbian images was running an updated kernel, that did not have anything in /lib/modules that matched.  So I was unable to update the WiFi drivers.  I found an article with the correct command to reinstall the Raspbian Kernel:

sudo apt-get install --reinstall raspberrypi-bootloader raspberrypi-kernel

So play time over and annoying problem accomplished I moved on to thinking about how to actually implement the bridge.  I think I'm going to setup two RaspberryPi's to make this bridge.  That will allow it to be more portable, and might make creating a educational guide for others to learn from easier.  (The alternative being to use the RPi access point that I already have as an end point.)

L2TPv3 (Layer 2 Tunneling Protocol Version 3) seems to be the key piece of technology that I need to make this work. :-)  I found that has a very succieient explination of L2TPv3.  While Wikipedia's L2TPv3 entry has some interesting history.
