base on # MTProxy Simple MT-Proto proxy ## Building Install dependencies, you would need common set of tools for building from source, and development packages for `openssl` and `zlib`. On Debian/Ubuntu: ```bash apt install git curl build-essential libssl-dev zlib1g-dev ``` On CentOS/RHEL: ```bash yum install openssl-devel zlib-devel yum groupinstall "Development Tools" ``` Clone the repo: ```bash git clone https://github.com/TelegramMessenger/MTProxy cd MTProxy ``` To build, simply run `make`, the binary will be in `objs/bin/mtproto-proxy`: ```bash make && cd objs/bin ``` If the build has failed, you should run `make clean` before building it again. ## Running 1. Obtain a secret, used to connect to telegram servers. ```bash 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. ```bash 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. ```bash head -c 16 /dev/urandom | xxd -ps ``` 4. Run `mtproto-proxy`: ```bash ./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 following schema: `tg://proxy?server=SERVER_NAME&port=PORT&secret=SECRET` (or let the official bot generate it for you). 6. Register your proxy with [@MTProxybot](https://t.me/MTProxybot) on Telegram. 7. Set received tag with arguments: `-P <proxy tag>` 8. Enjoy. ## Random padding Due to some ISPs detecting MTProxy by packet sizes, random padding is added to packets if such mode is enabled. It's only enabled for clients which request it. Add `dd` prefix to secret (`cafe...babe` => `ddcafe...babe`) to enable this mode on client side. ## Systemd example configuration 1. Create systemd service file (it's standard path for the most Linux distros, but you should check it before): ```bash nano /etc/systemd/system/MTProxy.service ``` 2. Edit this basic service (especially paths and params): ```bash [Unit] Description=MTProxy After=network.target [Service] Type=simple WorkingDirectory=/opt/MTProxy ExecStart=/opt/MTProxy/mtproto-proxy -u nobody -p 8888 -H 443 -S <secret> -P <proxy tag> <other params> Restart=on-failure [Install] WantedBy=multi-user.target ``` 3. Reload daemons: ```bash systemctl daemon-reload ``` 4. Test fresh MTProxy service: ```bash systemctl restart MTProxy.service # Check status, it should be active systemctl status MTProxy.service ``` 5. Enable it, to autostart service after reboot: ```bash systemctl enable MTProxy.service ``` ## Docker image Telegram is also providing [official Docker image](https://hub.docker.com/r/telegrammessenger/proxy/). Note: the image is outdated.
