TCP client

There have been countless times during penetration tests that I've needed

to whip up a TCP client to test for services, send garbage data, fuzz, or

any number of other tasks. If you are working within the confines of large

enterprise environments, you won't have the luxury of networking tools or

compilers, and sometimes you'll even be missing the absolute basics like the

ability to copy/paste or an Internet connection. This is where being able to

quickly create a TCP client comes in extremely handy. But enough jabbering

确实很多时候http不一定合适，需要直接用tcp来进行测试，

这里是一个简单的示例

package main

import (

"net"

"fmt"

)

var (

target_host = "127.0.0.1"

target_port = 80

)

func main() {

c, _ := net.Dial("tcp", fmt.Sprintf("%s:%d", target_host, target_port))

buf := make([]byte, 4096)

c.Write([]byte("GET / HTTP/1.1\r\n\r\n"))

n,_:=c.Read(buf)

fmt.Println(string(buf[:n]))

}
