base on A simple single file smart sni proxy with doh and dot written in go # Smart SNI and DNS Proxy Server This DNS Proxy Server is a Go-based server capable of handling both DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) requests. It features rate limiting and can process DNS queries based on a custom JSON configuration file. ## Features - **DNS-over-HTTPS (DoH):** Accepts and processes DNS queries over HTTPS. - **DNS-over-TLS (DoT):** Accepts and processes DNS queries over TLS. - **Rate Limiting:** Throttles the number of requests using a limiter. - **Custom Domain Handling:** Matches DNS queries to a list of specified domains and returns corresponding IP addresses. - **SNI Proxy:** Proxies non-matching domains to their respective addresses. - **Configurable:** Uses a `config.json` file to define behavior for specified domains. ## Configuration The server uses a `config.json` file which should be structured as follows: ```json { "host": "your.host.com", "domains": { "example.com": "1.2.3.4", "anotherdomain.com": "1.2.3.4" } } ``` Replace the IP addresses with your server's public IP to ensure transparent proxying(Here it's 1.2.3.4).\ \ You can use this code to proxy all domains(its not recommended) ```json { "host": "your.host.com", "domains": { ".": "1.2.3.4" } } ``` ## TLS Certificates The DoT and DOH servers expect TLS certificates to be located at `/etc/letsencrypt/live/your.host.com/`. Make sure you have valid certificates named `fullchain.pem` and `privkey.pem`.\ \ You can obtain a valid certificate for your domain with lets encrypt ## Auto Install ``` bash <(curl -fsSL https://raw.githubusercontent.com/bepass-org/smartSNI/main/install.sh) ``` ## Manual Setup 1. Install Requirements ```bash apt update apt install nginx certbot python3-certbot-nginx snap install go --classic ``` 2. Change server_name in /etc/nginx/sites-enabled/default to your `domain` 3. Obtain a valid certificate for nginx ```bash certbot --nginx -d <YOUR_DOMAIN> ``` 4. Clone the repository to your local machine. 5. Create and configure your `config.json` file. 6. Run `go build` to compile the server. 7. Run the compiled binary to start the server in tmux or in background with nohup. ```bash ./name-of-compiled-binary ``` ## Rate Limiting The server uses the `golang.org/x/time/rate` package to implement rate limiting. You can adjust the rate limiter in the `main` function to suit your needs. ## Contributions Contributions to this project are welcome.
