proxy your traffic through CDN using websocket

  • server
  • client

what does it do

• you can use this as a library in your project: go get -v -u github.com/jm33-m0/go-cdn2proxy
• simply put, go-cdn2proxy forwards your traffic through websocket, which can be implemented behind most CDNs
• anything that supports socks5 proxy can use go-cdn2proxy

for me, i wrote this for emp3r0r

example

server

package main

import (
    "log"

    cdn2proxy "github.com/jm33-m0/go-cdn2proxy"
)

func main() {
    err := cdn2proxy.StartServer("9000", "127.0.0.1:8000", os.Stderr)
    if err != nil {
        log.Fatal(err)
    }
}

client

package main

import (
    "log"

    cdn2proxy "github.com/jm33-m0/go-cdn2proxy"
)

func main() {
    err := cdn2proxy.StartProxy("127.0.0.1:10888", "wss://example.com/ws", "socks5://127.0.0.1:1080", "https://9.9.9.9/dns-query")
    if err != nil {
        log.Fatal(err)
    }
}

thanks

Functions

func Socks5Auth

func Socks5Auth(client net.Conn) (err error)

func StartProxy

func StartProxy(addr, wsurl, proxy, doh string) error

StartProxy on client side, start a socks5 proxy url: websocket server. eg: wss://example.com/path/to/ws use wss instead of ws since your reverse proxy (nginx, Cloudflare) should be using TLS addr: local proxy address, used as agent's outgoing proxy proxy: proxy for websocket connection, if you cannot directly connect to ws server, use this eg. socks5://127.0.0.1:1080 doh: DNS over HTTPS server, eg. https://9.9.9.9/dns-query, prevent DNS leaks

func StartServer

func StartServer(port, destAddr, wspath string, logOutput io.Writer) (err error)

StartServer start websocket server port: listen on 127.0.0.1:port destAddr: send everything here, we only want a single purpose proxy wspath: access this path to reach ws service, eg. /ws if you use go-cdn2proxy along with other HTTP server, prevent multiple `/`
