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

Migrate Maven packages from Sonatype Nexus to GitHub Packages

This gist describes the process we've used to migrate our Maven package repository from Sonatype Nexus to GitHub Packages. The same process could be used for migrating any Maven package repo that is in the standard layout.

We created a special repository on GitHub to hold all of our Maven packages. You might decide to migrate packages to different repositories, in which case invoke the script multiple times.

The script uses find to look for all of the folders containing poms and upload them. You specify the folder

I have a heterogenous set of hosts and a mix of different roles that I want to apply to each host. Using groups would mean creating a group for nearly every role, which felt like overkill.

This combination of a playbook and two task scripts runs the roles specified in the host's required_roles variable, in order. It supports a tag named after the role, to run the specific role, and a tag role-partial to activate the role but to require other tags to activate specific tasks in the role (helpful when debugging roles).

-- GEOIP IN POSTGRESQL
--

-- We use two approaches. First using PostgreSQL inet and cidr types and indexing (PostgreSQL 9.4 and later),
-- and then using ip4r (https://github.com/RhodiumToad/ip4r).
-- The performance of ip4r indexes is significantly better than PostgreSQL's own index.
-- An operation that took 42s using ip4r took 47 minutes using PostgreSQL's cidr index.
