GNU/Linux UFW VPN kill switch tutorial

GNU/Linux UFW VPN kill switch tutorial

This is a quick guide for setting up a kill switch using UFW (Uncomplicated FireWall). It is assumed you are using OpenVPN and optionally Network-Manager with network-manager-openvpn.

1. (Optional) IP Addresses

Before we can start we're going to need the IP address (or the IP addresses) of your VPN so that we can whitelist those later on, write them down. They are obviously going to be different for every VPN and VPNs with multiple servers, so I'll leave this up to you.

2. Install UFW

On some systems UFW is installed and enabled by default (Ubuntu, for example). Installation procedure is going to be different for every distribution of GNU/Linux, but it's usually something like

Vim without NERD tree or CtrlP

Vim without NERD tree or CtrlP

I used to use NERD tree for quite a while, then switched to CtrlP for something a little more lightweight. My setup now includes zero file browser or tree view, and instead uses native Vim fuzzy search and auto-directory switching.

Fuzzy Search

There is a super sweet feature in Vim whereby you can fuzzy find your files using **/*, e.g.:

:vs **/*<partial file name><Tab>

Create a private fork of a public repository

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

  1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git

No longer able to make public gists private — message to GitHub

We've been able to toggle visibility of gists since 2014 (https://github.com/blog/1837-change-the-visibility-of-your-gists), but I just noticed that I can no longer make public gists private. That is, when I edit private gists I still see the "Make Public" button, but not the other way round — there's only a "Delete" button when I edit public gists; the "Make Secret" which should be next to it (as shown in the screencast in the linked blog post) is nowhere to be found. I made a screenshot and a screencast demonstrating the issue, both of which are attached. Could you please confirm this issue? Was this an intentional change, and why? Thank you for your attention.
