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.

Badblocks on TrueNAS Scale

Connect your USB drive to the machine
Navigate to the TrueNAS Scale shell by opening the menu, going to System Settings and then clicking on Shell
Locate the drive's device ID using the lsblk command
Check the recommended block size using the command blockdev --getbsz /dev/<YOUR BLOCK DEVICE ID>
Note the block size you got from the last command
STOP! Have you ensured that the USB device does NOT have any important data on it? If it does, stop now, unplug it from the TrueNAS Scale machine and back it up elsewhere! Running the specific badblocks command we'll use will destroy data on the drive!
Okay, you've confirmed there is no data on the drive you need? Good!
Fire up a new tmux session tmux new -s badblocks_

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.
