mullvadclosest

A small golang program that checks your latency to all of the known mullvad relays.

This will use your local relay database as installed by the mullvad client if it finds it. Otherwise, it will use a bundled copy which may be a bit out of date. If that happens, contact me and I'll update it.

This will show you the top 25 lowest latency relays (VPN servers) to you, and the 5 highest for comparison.

Errata

The go ICMP ping library I'm using doesn't work on OSX if you're not root, so the program requires it. Oh well.

Usage

Make sure you're disconnected from the VPN when you run this. It needs to be able to ping the relays directly, and if you're connected to the VPN you'll get the latency through the VPN server to which you're connected, which is not what you want.

Run:

GOPROXY=direct go run sneak.berlin/go/mullvadclosest/cmd/mullvadclosest@4dd5e871f830ff62bb30c2290623ad9d8c4d4554

The GOPROXY=direct means to download the code directly from my servers, not the Google-operated golang module proxy. Given that you're running this program as root from a random place on the internet, downloading it directly from me avoids the case where Google can serve you arbitrary code that runs on your machine.

The full git commit hash is provided to ensure that you're running the specific version of the code that I've tested and that you're expecting to run. Don't do "git run @latest" because it's just granting random people code exec on your machine. (Same goes for docker images that use any tag that uses : instead of a specific hash identified by @.)

Example output

Run from the southwestern US:
