Since starting with a single Raspberry Pi about 18 months ago and tinkering with a DNS and DHCP server I've gradually added more hardware as I've looked into and researched networks, flavours of linux, firewalls, switches, IoT, virtualisation and so on. I had begun to build up more and more repos of my documents which overlapped more and more.
This is the merged repo for all the flavours of linux, networking, firewalls, virtualisation and anything else that comes up.
