tun2brookserver

Assume your brook server is 1.2.3.4:9999, password is hello

$ ipio tun2brookserver -s 1.2.3.4:9999 -p hello

ROOT privileges required, more $ ipio tun2brookserver -h

tun2brookwsserver

Assume your brook wsserver is ws://1.2.3.4:9999, password is hello

$ ipio tun2brookwsserver -s ws://1.2.3.4:9999 -p hello

ROOT privileges required, more $ ipio tun2brookwsserver -h

tun2socks

Assume your socks5 server is 1.2.3.4:1080

Interface

# Interface can be tun device, fd
type Interface interface {
    io.ReadWriteCloser
}

# Handler you need to implement
type Handler interface {
    TCP(conn net.Conn)
    UDP(conn net.Conn)
}

Tun2socks Example

import "github.com/txthinking/ipio"
import "github.com/txthinking/socks5"

type Socks5 struct{
}

func (t *Socks5) TCP(conn net.Conn) {
    c, _ := socks5.NewClient(server, username, password, 0, 60)
    rc, _ := c.Dial("tcp", conn.RemoteAddr().String()) 
    go io.Copy(conn, rc)
    io.Copy(rc, conn)
}

func (t *Socks5) UDP(conn net.Conn) {
    c, _ := socks5.NewClient(server, username, password, 0, 60)
    rc, _ := c.Dial("udp", conn.RemoteAddr().String()) 
    go io.Copy(conn, rc)
    io.Copy(rc, conn)
}

// func NewIPIO(t Interface, h Handler) *IPIO
ii := ipio.NewIPIO(tun, &Socks5{})

// func (t *IPIO) Run() error
ii.Run()

// func (t *IPIO) Close() error
ii.Close()
