Установка Outline VPN на Ubuntu 20.04

Outline VPN - это бесплатный инструмент с открытым исходным кодом, позволяющий развернуть собственную VPN на Вашем собственном сервере или на машине облачного провайдера. Подробную информацию Вы можете узнать здесь и здесь.

В своем составе имеет как графические инструменты, так и средства работы через командную строку. Позволяет использовать VPN как на настольных компьютерах, так и на мобильных устройствах.

Прежде чем начать

Вам нужен сервер. Да, его нужно арендовать, учитывая его местоположение. Например, если Вам нужно получать доступ к ресурсам, которые недоступны в текущем местоположении, но доступны, например, в Канаде, то смело арендуйте виртуальную машину в AWS, Digital Ocean или любом другом месте.

Using Github with Two Factor Auth.

It's a fairly common complaint that after enabling github two factor authentication that command line utilities stop working. The underlying issue is command line utilities send your username and password with each request to github, using two factor authentication disables github from accepting just your username and password, so your command line utilities such as git appear to stop working. Github will still accept a personal access token instead of your password however.

	This script is useful when you want to check equality of random results.
	Run testingRandom with function and limit of checks
	More checks = more accurate
	Example: testingRandom(() => Math.random().toFixed(1), 10000)
	Output:
	0.0 *********
	0.1 *******************
	0.2 *******************
	0.3 ******************

	Ignore all that craziness below. These can be set from the cli with the "pritunl" command.

	The commands below can be used to get/set the values of the cert, key, port and if the :80 -> "app.server_port" redirect is active.


	# Get current SSL server cert:
	pritunl get app.server_cert

	# Get current SSL server key:
	pritunl get app.server_key
