How to set up a Telegram Proxy (MTProxy)

This tutorial will teach you how to set up a Telegram MTProxy on an Ubuntu 22.04 sever using AWS Lightsail, although you can use any other Linux distribution and cloud provider.

Using a Telegram proxy is a safe, easy and effective way of overcoming Telegram bans. It's useful, for example, to keep using Telegram under tyrannical regimes, or to circumvent judges' decisions to block Telegram.

Telegram proxies are a built-in feature in all Telegram apps (both mobile and desktop). It allows Telegram users to connect to a proxy in just one or two clicks / taps.

Telegram proxies are safe: Telegram sends messages using their own MTProto secure protocol, and the proxy can only see encrypted traffic – there's no way for a proxy to decrypt the traffic and read the messages. The proxy does not even know which Telegram users are using the proxy, all the proxy sees is just a list of IPs.

☁️ How I got off the cloud and migrated everything from AWS to a VPS in Hetzner

This is an opinionated handbook on how I migrated all my Rails apps off the cloud and into VPS.

This is how I manage real production loads for my Rails apps. It assumes:

Rails 7+
Ruby 3+
PostgreSQL
Ubuntu Server 24.04
Capistrano, Puma, Nginx

	#!/bin/bash

	# Production Docker Host Hardening Script v2
	# For Ubuntu Server 24.04 LTS (Noble)
	# Suitable for both Kamal deployment and builder hosts

	set -euo pipefail
	IFS=$'\n\t'

	# --- Constants ---

	#!/bin/bash

	# This script takes a clean Ubuntu Server 24.04 LTS image and installs and configures
	# everything needed to deploy a production-ready PostgreSQL server.

	set -euo pipefail

	# --- AESTHETICS ---

	GREEN='\033[0;32m'

	#!/bin/bash

	# Production-Ready Listmonk Setup Script
	# This script sets up Listmonk with Docker Compose, Nginx reverse proxy, and automatic SSL

	set -euo pipefail

	# Function to generate a secure random password
	generate_password() {
	openssl rand -base64 32 \| tr -d /=+ \| cut -c -32

	#!/bin/bash

	# Production-Ready Umami Setup Script
	# This script sets up Umami with Docker Compose, Nginx reverse proxy, and automatic SSL

	set -euo pipefail

	# Function to generate a secure random password
	generate_password() {
	openssl rand -base64 32 \| tr -d /=+ \| cut -c -32

	#!/bin/bash

	# Production Docker Host Setup Script
	# This script sets up a secure, production-ready Docker host on Ubuntu Server 22.04 LTS
	# It includes security hardening, performance optimizations, and best practices
	# CAUTION: This script makes significant system changes. Use at your own risk.

	set -euo pipefail

	sudo apt-get update -y
	sudo apt-get upgrade -y

	sudo apt-get install -y ufw

	#!/bin/bash

	# This scrips takes a clean AWS Amazon Linux 2023 AMI and installs and configures
	# everything needed to deploy a Rails app to it using Kamal.
	# The resulting state is a clean instance ready to accept Kamal (Dockerized) apps.
