Install L2TP IPsec Connection on Ubuntu 18.04

L2TP on its own is not secure enough, so we’ll need to pair this protocol with IPSec.

To establish an L2TP VPN connection from the Ubuntu command line, we must first install strongswan and xl2tpd

Install requirements

We’re going to use StrongSwan for IPSec.

apt-get install strongswan xl2tpd -y

I'm running into the same issue. Using python venv I was able to get certbot working using pip.

Steps: Install virtualenv

pip install virtualenv --upgrade

Create a virtualenv

virtualenv -p /usr/bin/python2.7 certbot

Multiple MySQL Versions with Homebrew

For homebrew version 1.5.12 - WIP... not quite working yet.

brew -v # => Homebrew 1.5.12

Install the current version of mysql.

# Install current mysql version

brew install mysql

Multiple MySQL versions on MacOS with Homebrew

At the time of writing (december 2018), there aren’t any up-to-date and easy to apply guides on how to switch between different MySQL version on a Mac using Homebrew . Or at least, I didn’t find any.

So I picked up a few things here and there and finally managed to connect all the pieces of the puzzle. I hope this guide can help you and the future me. If anyone knows of a better way to accomplish this, I do hope they will share their insight :)

The basic idea here is that you need to install all MySQL versions one at a time and assign each its own data directory.

I am using Homebrew 1.8.5. (brew -v)

Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096

	# Download this files
	- openssl.conf
	- openssl-tsa.conf
	- testing.txt
	- tsaserial


	# Generate CA Certificate
	openssl req -new -newkey rsa:4096 -nodes -out ca.csr -keyout ca.key -config openssl.conf
	openssl x509 -trustout -signkey ca.key -days 1461 -req -in ca.csr -out ca.pem
