This is an efficient and lightweight implementation of a SOCKS5 Proxy written in pure Go (Golang) without any dependencies. The proxy supports key features like CONNECT, BIND, and AUTH (both with and without username/password authentication, and GSSAPI SOCKS5 authentication flow).
This project is currently active and maintained. We aim to continually improve its performance and feature set. Feedback and contributions are greatly appreciated!
This project fully implements all the requirements outlined in the specifications of RFC 1928, RFC 1929, and RFC 1961, with the exception of the UDP ASSOCIATE command, which may be implemented in the future.
- CONNECT command: Standard command for connecting to a destination server.
- Custom CONNECT: Allows creating customs tunnels to destination server.
- BIND command: Allows incoming connections on a specified IP and port.
- AUTH support:
- No authentication (anonymous access);
- Username/Password authentication (rfc1929);
- GSSAPI SOCKS5 protocol flow (rfc1961);
- Custom BIND command (bind callback).
func main() {
opts := Options{
AllowNoAuth: true,
}
socks5, _ := New(opts)
ls, _ := net.Listen("tcp", ":1080")
for {
conn, _ := ls.Accept() // accept new client connection
socks5.Handle(conn, nil) // run socks5 over client connection
}
}Check this out to use socks5 server. You can pull the ready-to-use image from Docker Hub.
We welcome contributions to enhance the functionality and performance of this Socks5 proxy. If you find any bugs or have feature requests, feel free to open an issue or submit a pull request.
