Wireguard Optimal MTU

About

  • I faced bandwidth issues between a WG Peer and a WG server. Download bandwidth when downloading from WG Server to WG peer was reduced significantly and upload bandwidth was practically non existent.
  • I found a few reddit posts that said that we need to choose the right MTU. So I wrote a script to find an optimal MTU.
  • Ideally I would have liked to have run all possible MTU configurations for both WG Server and WG Peer but for simplicity I choose to fix the WG Server to the original 1420 MTU and tried all MTUs from 1280 to 1500 for the WG Peer.

Testing

  • On WG server, I started an iperf3 server
  • On WG peer, I wrote a script that does the following:
    • wg-quick down wg0
  • Edit MTU in the /etc/wireguard/wg0.conf file

Setting up qemu VM using nix flakes

Did you know that it is rather easy to setup a VM to test your NixOs configuration?

Create simple flake:

Git rebase from remote fork repo

In your local clone of your forked repository, you can add the original GitHub repository as a "remote". ("Remotes" are like nicknames for the URLs of repositories - origin is one, for example.) Then you can fetch all the branches from that upstream repository, and rebase your work to continue working on the upstream version. In terms of commands that might look like:

Add the remote, call it "upstream":

git remote add upstream https://github.com/whoever/whatever.git

Fetch all the branches of that remote into remote-tracking branches, such as upstream/master:

git fetch upstream

How to squash commits in a GitHub pull request

How to squash commits in a GitHub pull request

o you've contributed some code to an open source project, say, Rails. And they'd like you to squash all of the commits in your pull request. But you're not a git wizard; how do you make this happen?

Normally, you'd do something like this. I'm assuming upstream is a git remote that is pointing at the official project repository, and that your changes are in your 'omgpull' branch:
