MTProxy

Install dependencies, you would need common set of tools for building from source, and development packages for openssl and zlib.

On Debian/Ubuntu:

apt install build-essential libssl-dev zlib1g-dev

On CentOS/RHEL:

yum install openssl-devel zlib-devel
yum groupinstall "Development Tools"

To build, simply run make. Your binary will be in objs/bin/mtproto-proxy. If build was failed, you would do make clear at first, before building it again.

1. Obtain a secret, used to connect to telegram servers.

curl -s https://core.telegram.org/getProxySecret -o proxy-secret

2. Obtain current telegram configuration. It can change (occasionally), so we encourage you to update it once per day.

curl -s https://core.telegram.org/getProxyConfig -o proxy-multi.conf

3. Generate a secret to be used by users to connect to your proxy.

head -c 16 /dev/urandom | xxd -ps

4. Run mtproto-proxy:

./mtproto-proxy -u nobody -p 8888 -H 443 -S <secret> --aes-pwd proxy-secret proxy-multi.conf -M 1

... where:

• nobody is the username. mtproto-proxy calls setuid() to drop privilegies.
• 443 is the port, used by clients to connect to the proxy.
• 8888 is the local port. You can use it to get statistics from mtproto-proxy. Like wget localhost:8888/stats. You can only get this stat via loopback.
• <secret> is the secret generated at step 3. Also you can set multiple secrets: -S <secret1> -S <secret2>.
• proxy-secret and proxy-multi.conf are obtained at steps 1 and 2.
• 1 is the number of workers. You can increase the number of workers, if you have a powerful server.
• also feel free to check out other options using mtproto-proxy --help.

5. Generate the link with followed schema: tg://proxy?server=SERVER_NAME&port=443&secret=SECRET (by the way official bot provides links anyway).
6. Register your proxy with @MTProxybot on Telegram.
7. Set received tag as param -P <proxy tag>
8. Enjoy.

1. Create systemd service file (it's standart path for the most Linux distros, but you should check it before):

nano /etc/systemd/system/MTProxy.service

2. Edit this basic service (especially paths and params):

[Unit]
Description=MTProxy
After=network.target

[Service]
Type=simple
WorkingDirectory=/opt/MTProxy/objs/bin
ExecStart=/opt/MTProxy/objs/bin/mtproto-proxy -u nobody -p 8888 -H 443 -S <secret> -P <tag> [other params]
Restart=on-failure

[Install]
WantedBy=multi-user.target

3. Reload daemons:

systemctl daemon-reload

4. Test fresh MTProxy service:

systemctl restart MTProxy.service
# Check status, it should be active
systemctl status MTProxy.service

5. Enable it, to autostart service after reboot:

systemctl enable MTProxy.service

Telegram is also providing official Docker image.
