Networking

Late Night in the Lab

There is something about a university computer lab at 11pm that feels different to working during the day. Everyone else has gone home. The building is quiet. You can actually think.

Methindu, Mithila and I stayed back to work on some networking concepts we had been meaning to get hands on with. We needed access to the rack equipment and the lab gives us that without having to simulate everything in Packet Tracer. There is only so much you can learn from a diagram.

Setting Up a WireGuard VPN From Scratch

I run my own web server at home. It works fine when I am sitting next to it. The problem is when I am not.

I wanted a way to SSH in and edit files on my site from anywhere without exposing everything to the open internet. The answer was a VPN. Specifically WireGuard, which is supposed to be the modern way to do this.

It took longer than I expected :(
