Reverse Engineering Golang

Some notes, tools, and techniques for reverse engineering Golang binaries.

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.

The following solution thanks to @hackerzgz & @snacky101 will install all nerd fonts;

brew tap homebrew/cask-fonts
brew search '/font-.*-nerd-font/' | awk '{ print $1 }' | xargs -I{} brew install --cask {} || true

	# It is a curated list of my bash history. I entered other commands so hopefully I got the right ones here.

	yum upgrade
	reboot

	dnf install yum-utils
	rpmconf -a # answer "n" to both things

	# Simple example to deploy traefik with consul connect enabled.
	# For simplicity the job includes traefik as well as the backend service.
	# Please note that traefik currently only supports connect for HTTP.

	import asyncio

	# Ref: https://docs.python.org/3/library/asyncio-eventloop.html#asyncio.get_event_loop
	# > If there is no current event loop set in the current OS thread,
	# > the OS thread is main, and set_event_loop() has not yet been called,
	# > asyncio will create a new event loop and set it as the current one
	loop = asyncio.get_event_loop()

	# So, loop2 is loop
	loop2 = asyncio.get_event_loop()

	Go step-by-step through following instructions to set up L2TP/IPSec VPN on Centos 7.

	To set up the VPN client on centos 7, first install the following packages:

	yum -y install epel-release
	yum -y install strongswan xl2tpd

	Create VPN variables (replace with actual values):
	VPN_SERVER_IP='your_vpn_server_ip'
