Installation

go get github.com/JC5LZiy3HVfV5ux/socks5

Getting Started

Create your .go file. For example: main.go.

package main

import (
	"context"
	"log"
	"os"
	"os/signal"

	"github.com/JC5LZiy3HVfV5ux/socks5"
)

func main() {
	ctx, stop := signal.NotifyContext(context.Background(), os.Interrupt)
	defer stop()

	srv := socks5.New()

	go func() {
		if err := srv.ListenAndServe(); err != nil {
			log.Fatal(err)
		}
	}()

	<-ctx.Done()

	if err := srv.Shutdown(); err != nil {
		log.Fatal(err)
	}
}

Run your server:

go run main.go

The following curl example shows how to use the proxy server:

curl -x socks5://127.0.0.1:1080 http://example.com

See the tests for more information about package.

FAQ

• Why can't connect to socks proxy server?

  Not all applications and browsers support socks authentication or socks protocol. You may need extension for Chrome or another browser. The proof of work for the UDP association was done using qBittorrent - a BitTorrent client.

If you have any questions, you can ask in GitHub Discussions.
