strongSwan setup for Road Warriors on macOS 10.12, iOS 10 and Windows 10

This setup is for remote users to connect into an office/home LAN using a VPN (ipsec). This is based on (but not the same as) the strongSwan documentation and this guide: https://raymii.org/s/tutorials/IPSEC_vpn_with_Ubuntu_16.04.html

I used strongSwan 5.5.1.

apt-get install -y strongswan strongswan-pki

Screencapture and animated gifs

I say "animated gif" but in reality I think it's irresponsible to be serving "real" GIF files to people now. You should be serving gfy's, gifv's, webm, mp4s, whatever. They're a fraction of the filesize making it easier for you to deliver high fidelity, full color animation very quickly, especially on bad mobile connections. (But I suppose if you're just doing this for small audiences (like bug reporting), then LICEcap is a good solution).

Capturing (Easy)

1. Launch quicktime player
2. do Screen recording

Overview

The intention is to get a clean build of MRI 1.8.7 and 1.9.3.

MRI 1.8.7 doesn't play nicely with LLVM based GCC compilers. In Mountain Lion, the only way to get a non-LLVM gcc is to build one yourself. The command line tools package in Xcode 4.4 does not contain a non-llvm based GCC.

Checklist

1. Upgrade to Mountain Lion
2. Remove all previous copies of Xcode
