My OS X “VPN only” Setup For #30C3

You should never let passwords or private data be transmitted over an untrusted network (your neighbor’s, the one at Starbucks or the company) anyway, but on a hacker congress like the #30C3, this rule is almost vital.

Hackers get bored easily, and when they’re bored, they’re starting to look for things to play with. And a network with several thousand connected users is certainly an interesting thing to play with. Some of them might start intercepting the data on the network or do other nasty things with the packets that they can get.

If these packets are encrypted, messing with them is much harder (but not impossible! – see the end of this article). So you want your packets to be always encrypted. And the best way to do that is by using a VPN.

Golang installation guide

Since Golang version 1.11 this process is finally (almost) as easy as it should (!!). You can see full docs here. For older guides see here.

These are my notes, not a generic solution. They are not meant to work anywhere outside my machines. Update version numbers to whatever are the current ones while you do this.

Installing everything needed the first time

Install asdf and its golang plugin, then install golang
