Currently this site is being generated offline as a series of static images, HTML, CSS, and JS files that get served almost entirely out of cache through the CDN provided by Cloudflare. This is made possible by a piece of software called Hugo.

Introduction Why Bother? As should be abundantly clear from my prior writings I am about to leave on a trip for a year. During that time I'll likely be making use of numerous public Wi-Fi access points, not to mention whatever dodgy cellular providers are available in each location I travel to. As part of my overall stance on privacy, its essential I take steps to secure my communication while traveling, the primary of which is using a VPN for basically everything on both my laptop and my phone.
Just a quick post to share this with anyone else that needs it. I spent hours using Google and reading posts from random people on the net, including bug comments from Dan Walsh on a never solved Fedora bug specifically related to this. The conclusion I came to was that hardly anyone uses SELinux and the ones that do just hack around the problem rather than solving it. In this particular case, the fault is really with the terrible implementation of Google Authenticator, which I found out during the course of this by reading through the source code.
This post was originally a response to a question I received from a friend via email, with some additions. I'm not going to try to get very in-depth here, this is more of a high-level overview of what you should be doing to secure a server running Linux. This is mainly focused on a business environment where you have multiple users and multiple servers (and are hopefully using configuration management software).
