1.4.3 扫描速度比 1.4.2 慢很多 #31

Ti0oik · 2024-12-30T10:23:06Z

1.4.3版本，除了加了ipv6支持外，是不是还改了一下扫描配速的配置，我用1.4.3扫机器开放的端口的时候，发现同时扫五个IP的1-65535端口，二十多分钟才能扫完，1.4.2大概一分钟搞定。代码如下，调用的时候会多协程调用OpenPorts，传入单个ip地址：

func OpenPorts(ip string, portList []int) []int {
	b, err := json.Marshal(portList)
	if err != nil {
		logger.Error("Marshal portList get error:", err)
		return portList
	}

	pNum := len(portList)
	portStr := string(b)
	portStr = portStr[1 : len(portStr)-1]
	single := make(chan struct{})
	retChan := make(chan port.OpenIpPort, pNum)
	ports, err := port.ShuffleParseAndMergeTopPorts(portStr)
	if err != nil || len(ports) < 1 {
		logger.Error("Parse portList get error:", err)
		return portList
	}

	retPortList := []int{}
	go func() {
		for ret := range retChan {
			retPortList = append(retPortList, int(ret.Port))
		}
		single <- struct{}{}
	}()

	// parse ip
	addrType, err := common.JudgeHostType(ip)
	if addrType == common.INVALID {
		logger.Error("invalid ip:", ip)
		return portList
	}

	if addrType == common.DOMAIN {
		ctx, cancel := context.WithTimeout(context.Background(), 3*time.Second)
		defer cancel()

		r := net.Resolver{}
		ips, err := r.LookupIP(ctx, "ip", ip)
		if err != nil {
			logger.Error("LookupIP get error:", err, " ip:", ip)
			return portList
		}

		if len(ips) > 0 {
			ip = ips[0].String()
		}
	}

	it, startIp, _ := iprange.NewIter(ip)
	ss, err := syn.NewSynScanner(startIp, retChan, syn.DefaultSynOption)
	if err != nil {
		logger.Error("NewSynScanner get error:", err, " ip:", ip)
		return portList
	}

	portScan := func(ip net.IP) {
		for _, _port := range ports {
			ss.WaitLimiter()
			ss.Scan(ip, _port, port.IpOption{})
		}
	}

	var wgPing sync.WaitGroup
	poolPing, _ := ants.NewPoolWithFunc(50, func(ip interface{}) {
		_ip := ip.(net.IP)
		portScan(_ip)
		wgPing.Done()
	})
	defer poolPing.Release()

	for i := uint64(0); i < it.TotalNum(); i++ {
		ip := make(net.IP, len(it.GetIpByIndex(0)))
		copy(ip, it.GetIpByIndex(i))
		wgPing.Add(1)
		poolPing.Invoke(ip)
	}

	wgPing.Wait()
	ss.Wait()
	ss.Close()
	<-single
	return retPortList
}

对速度影响的还有一个提交，自适应速率，如果发包速率超过了网卡发包的能力就会降速，3e96b21 你添加个 -debug 参数看看输出，作为lib使用的时候对应参数是port.ScannerOption{   Debug: true,  }

好嘞，我试试

Ti0oik · 2024-12-30T13:25:09Z

@XinRoom 配置里加了个debug以外，别的和syn.DefaultSynOption的配置一样，limiter是1500。感觉单独跑一个IP和同时跑多个IP，debug打印出来的限速差不多。我可以自己排查下是不是网速的问题吗?

单独跑一个IP是这样：

@XinRoom 大哥我知道了，中午跑得慢应该是我网速的问题，现在到晚上了就很快了

XinRoom · 2024-12-31T01:19:47Z

@XinRoom 配置里加了个debug以外，别的和syn.DefaultSynOption的配置一样，limiter是1500。感觉单独跑一个IP和同时跑多个IP，debug打印出来的限速差不多。我可以自己排查下是不是网速的问题吗?

单独跑一个IP是这样：

看syn速度，大概率用的wifi，网线速度的话一般是这个的10倍
syn模式不管多少个ip一起扫描，速度是一样的，都受网卡最大的小包发包数限制

XinRoom · 2024-12-31T01:28:22Z

如果同一网络环境下，1.4.3 与 1.4.2版本扫描速度在网卡最大发包数（比如调试信息显示该网卡最大1000左右）的限制下有很大差距的话，可以再提下问题。
或者我把这个自适应速度功能改成option？但是如果超过网卡最大发包数，是会导致丢包，必然会使得结果不准。

@XinRoom 不用改成option，你那个策略是对的，自动按照网卡限速来调整比较好
