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

Installing and configuring Powerline-style command line tools for developers (OSX)

Intro:

For every developer, terminal is their weapon, so why don't you customize it to become a powerful, and a beautiful weapon?

Powerline style refers to a terminal style that helps developer to keep track of their workflow easily, allows them to have perfect visual on current directories and new changes. It is also git recognizable, and failure detector that will help your development process becomes more interact and much faster.

In this guideline, I will introduce you with 2 smart shells: Zsh and Fishshell. Both are perfect for the development jobs due to its rich of resources, and user-friendly.

UFW

I use Ubuntu’s Uncomplicated firewall because it is available on Ubuntu and it's very simple.

Install UFW

if ufw is not installed by default be sure to install it first.
