Fuzzer在复制Python一中[关闭]

Question

I'm recreating a fuzzer(the actual fuzzer is on the link and it's written in python) for this tutorial:

Link for the tutorial

well actually the objective is to do all of the code but using Go.

**My question is more in terms of a correct way to do things the process to reach big incremental numbers in the code are getting slower and slower. Anyone have any ideia if there of a interface/lib that does this. Or any functionality that i´m forgeting in Go that could be use to do it better.:

package main

import (
    "fmt"
    "net"
    "strings"
)

const payload = "\x41"

func main() {
    //Banner
    fmt.Printf("
Lauching Fuzzer..
")
    payL := strings.Repeat(payload, 50)

    for {
        payL += strings.Repeat(payload, 50)
        conn, err := net.Dial("tcp", "localhost:21")
        if err != nil {
            fmt.Println("Crash Error: ", err)
        }
        final_payload := fmt.Sprint("User " + payL + "
")
        _, err = conn.Write([]byte(final_payload))
        if err != nil {
            fmt.Println("Error: ", err)
            break
        } else {
            fmt.Println("Sending buffer with length: ", final_payload)
            conn.Close()
        }

    }

package fuzz

import "github.com/google/gofuzz"

Package fuzz is a library for populating go objects with random values.

For an example of an efficient Go fuzzer, see the Go package fuzz.
