Masscan

What is masscan

masscan is an Internet-scale port scanner, useful for large scale surveys of the Internet, or of internal networks. While the default transmit rate is only 100 packets/second, it can optional go as fast as 25 million packets/second, a rate sufficient to scan the Internet in 3 minutes for one port.

Installation

go get github.com/seaung/masscan

Special Instructions

This library depends on masscan, so you need to install masscan in your system in advance. since the execution of masscan requires root permission, you must ensure that you have root permission

Supported features

• Support some parameters of masscan scanner

TODO

• Constantly improve this library

Simple example

package main

import (
	"context"
	"fmt"
	"github.com/seaung/masscan"
	"time"
	"log"
)

func main() {
	cxt, cancel := context.WithTimeout(context.Background(), time.Minute * 5)
	defer cancel()

	masscanScanner, err := masscan.NewMasscanScanner(
		masscan.WithTargets("192.168.1.106"),
		masscan.WithPorts("0-8000"),
		masscan.WithBanners(),
		masscan.WithContext(cxt),
	)

	if err != nil {
		log.Fatalf("unable to create masscan scan: %v\n", err)
	}

	result, _, err := masscanScanner.Run()
	if err != nil {
		log.Fatalf("unable to run masscan scan: %v\n", err)
		return
	}

	for _, host := range result.Hosts {
		fmt.Printf("Address : %s - Address Type : %s\n", host.Address.Addr, host.Address.AddrType)

		for _, port := range host.Ports {
			fmt.Printf("Port : %s - State : %s - Protocol : %s\n", port.ID, port.State.State, port.Protocol)
		}
	}
}
