shadowsocks

Documentation

Overview

Package shadowsocks implements shadowsocks protocol.

Reference

https://github.com/shadowsocks/shadowsocks-org/wiki/Protocol

https://github.com/shadowsocks/shadowsocks-org/wiki/AEAD-Ciphers

参考阅读 http://overtalk.site/2020/02/25/network-shadowsocks/

注意, shadowsocks 可能同时使用tcp和udp，但是一定会使用到 tcp, shadowsocks 的network只能设置为tcp或者dual

如dual话，特征必很明显。

另外，本包是普通的ss AEAD Ciphers ，不过它还是有问题。所以以后要研究ss-2022

https://github.com/shadowsocks/shadowsocks-org/issues/183

关于ss-2022 https://github.com/shadowsocks/shadowsocks-org/issues/196

Functions

func GetAddrFrom

func GetAddrFrom(buf utils.ByteReader) (addr netLayer.Addr, err error)

依照shadowsocks协议的格式读取 地址的域名、ip、port信息 (same as socks5 and trojan)

type Client struct {
	proxy.Base
	utils.UserPass
	// contains filtered or unexported fields
}
