go.socks5

这是在拥有特定场景情况下使用的socks5服务程序

场景1:
1. 有个只能 windows 连的 vpn
2. 开个windows，把 socks5 代理服务一放上去
3. 然后我在我的linux机器上用 socks5 代理上网

这是 Makefile 内容

你可以执行 make 构建出所有目标机器的可执行文件

你可以执行 make linux 来只构建 linux amd64(x86_64) 架构的程序

all: linux windows macos
    @echo builded

windows:
    GOOS=windows GOARCH=amd64 go build -o bin/socks5-windows.exe cmd/main.go

linux:
    GOOS=linux GOARCH=amd64 go build -o bin/socks5-linux cmd/main.go

macos:
    GOOS=darwin GOARCH=amd64 go build -o bin/socks5-darwin cmd/main.go

已实现部分
1. 基于 tcp socket，也仅实现了 tcp 代理
2. 使用无验证方式，虽然协议中有各种验证方案
3. 相比原始从 BV1qA4y1D74u 视频中增加了坑爆破访问，也就是一些小细节处。
