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

How to make Powershell remember the SSH key passphrase.

You should not use the Open SSH client that comes with Git for Windows. Instead, Windows 10 has its own implementation of Open SSH that is integrated with the system. To achieve this:

  1. Start the ssh-agent from Windows Services:
  • Type Services in the Start Menu or Win+R and then type services.msc to launch the Services window;
  • Find the OpenSSH Authentication Agent in the list and double click on it;
  • In the OpenSSH Authentication Agent Properties window that appears, choose Automatic from the Startup type: dropdown and click Start from Service status:. Make sure it now says Service status: Running.
  1. Configure Git to use the Windows 10 implementation of OpenSSH by issuing the following command in Powershell:
git config --global core.sshCommand C:/Windows/System32/OpenSSH/ssh.exe
