Feature
- Syn stateless scan
- Syn Automatic ARP detection on the Intranet
- Scanning for large address segments has low occupancy (by iprange)
- Scanning the address is shuffled
- Concurrent high performance (by ants)
- TCP scan
- Port Fingerprint Identification
- HTTP Service Detection

"sync"
"time"
)
func main() {
single := make(chan struct{})
retChan := make(chan port.OpenIpPort, 65535)
go func() {
for ret := range retChan {
log.Println(ret)
}
single <- struct{}{}
}()
// 解析端口字符串并且优先发送 TopTcpPorts 中的端口, eg: 1-65535,top1000
ports, err := port.ShuffleParseAndMergeTopPorts("top1000")
if err != nil {
log.Fatal(err)
}
// parse ip
it, startIp, _ := iprange.NewIter("1.1.1.1/30")
// scanner
ss, err := syn.NewSynScanner(startIp, retChan, syn.DefaultSynOption)
if err != nil {
log.Fatal(err)
}
// port scan func
portScan := func(ip net.IP) {
for _, _port := range ports { // port
ss.WaitLimiter()
ss.Scan(ip, _port) // syn 不能并发，默认以网卡和驱动最高性能发包
}
}
// Pool - ping and port scan
var wgPing sync.WaitGroup
poolPing, _ := ants.NewPoolWithFunc(50, func(ip interface{}) {
_ip := ip.(net.IP)
if host.IsLive(_ip.String(), true, 800*time.Millisecond) {
portScan(_ip)
}
wgPing.Done()
})
defer poolPing.Release()
start := time.Now()
for i := uint64(0); i < it.TotalNum(); i++ { // ip索引
ip := make(net.IP, len(it.GetIpByIndex(0)))
copy(ip, it.GetIpByIndex(i)) // Note: dup copy []byte when concurrent (GetIpByIndex not to do dup copy)
wgPing.Add(1)
poolPing.Invoke(ip)
}
wgPing.Wait()
ss.Close()
<-single
log.Println(time.Since(start))

func main() {
single := make(chan struct{})
retChan := make(chan port.OpenIpPort, 65535)
go func() {
for ret := range retChan {
log.Println(ret)
}
single <- struct{}{}
}()
// 解析端口字符串并且优先发送 TopTcpPorts 中的端口, eg: 1-65535,top1000
ports, err := port.ShuffleParseAndMergeTopPorts("top1000")
if err != nil {
log.Fatal(err)
}
// parse Ip
it, _, _ := iprange.NewIter("1.1.1.1/30")
// scanner
ss, err := tcp.NewTcpScanner(retChan, tcp.DefaultTcpOption)
if err != nil {
log.Fatal(err)
}
// port scan func
portScan := func(ip net.IP) {
for _, _port := range ports { // port
ss.WaitLimiter()
ss.Scan(ip, _port) // syn 不能并发，默认以网卡和驱动最高性能发包
}
}
// Pool - ping and port scan
var wgPing sync.WaitGroup
poolPing, _ := ants.NewPoolWithFunc(50, func(ip interface{}) {
_ip := ip.(net.IP)
if host.IsLive(_ip.String(), true, 800*time.Millisecond) {
portScan(_ip)
}
wgPing.Done()
})
defer poolPing.Release()
start := time.Now()
for i := uint64(0); i < it.TotalNum(); i++ { // ip索引
ip := make(net.IP, len(it.GetIpByIndex(0)))
copy(ip, it.GetIpByIndex(i)) // Note: dup copy []byte when concurrent (GetIpByIndex not to do dup copy)
wgPing.Add(1)
poolPing.Invoke(ip)
}
wgPing.Wait()
ss.Close()
<-single
log.Println(time.Since(start))
}
3. Http/Port Finger
Http Web Cms Finger
// "github.com/XinRoom/go-portScan/core/port/fingerprint"
func ProbeHttpInfo(net.ParseIP("1.1.1.1"), 443, 5*time.Second) (httpInfo *port.HttpInfo, banner []byte, isDailErr bool)
// "github.com/XinRoom/go-portScan/core/port/fingerprint/webfinger"
func WebFingerIdent(resp *http.Response) (names []string)
Tcp Port Service Finger
// "github.com/XinRoom/go-portScan/core/port/fingerprint"
func PortIdentify(network string, ip net.IP, _port uint16, dailTimeout time.Duration) (serviceName string, banner []byte, isDailErr bool)

Cmd Build
普通编译
git clone https://github.com/XinRoom/go-portScan
cd go-portScan
go get -d -u ./...
go build -trimpath -ldflags="-s -w" -tags urfave_cli_no_docs cmd/go-portScan.go
Linux静态链接编译（需要docker环境）
sh ./build/build_static_alpine.sh
禁用syn模块，只保留tcp的编译(以便能在未安装pcap的windows机子上运行)
go build -trimpath -ldflags="-s -w" -tags urfave_cli_no_docs,nosyn cmd/go-portScan.go
Cmd Usage
.\go-portScan.exe -ip 1.1.1.1/30 [-p str] [-Pn] [-sT] [-sV] [-httpx] [-rate num] [-rateP num] [-timeout num(ms)]
NAME:
PortScan - A new cli application
USAGE:
PortScan [global options] command [command options] [arguments...]
DESCRIPTION:
High-performance port scanner
COMMANDS:
help, h Shows a list of commands or help for one command
GLOBAL OPTIONS:
--ip value target ip, eg: "1.1.1.1/30,1.1.1.1-1.1.1.2,1.1.1.1-2"
--iL value target ip file, eg: "ips.txt"
--port value, -p value eg: "top1000,5612,65120,-" (default: "top1000")
--Pn no ping probe (default: false)
--rateP value, --rp value concurrent num when ping probe each ip (default: 300)
--PT use TCP-PING mode (default: false)
--sT TCP-mode(support IPv4 and IPv6) (default: false)
--timeout value, --to value TCP-mode SYN-mode timeout. unit is ms. (default: 800)
--sS Use SYN-mode(Only IPv4) (default: true)
--nexthop value, --nh value specified nexthop gw add to pcap dev
--rate value, -r value number of packets sent per second. If set -1, TCP-mode is 1000, SYN-mode is 1500(SYN-mode is restricted by the network adapter, 2000=1M) (default: -1)
--devices, --ld list devices name (default: false)
--sV port service identify (default: false)
--httpx http server identify (default: false)
--netLive Detect live C-class networks, eg: -ip 192.168.0.0/16,172.16.0.0/12,10.0.0.0/8 (default: false)
--maxOpenPort value, --mop value Stop the ip scan, when the number of open-port is maxOpenPort (default: 0)
--oCsv value, --oC value output csv file
--oFile value, -o value output to file
--help, -h show help (default: false)
关键参数说明：
--Pn 在目标禁止PING时使用
--rate 在网络不稳定时（互联网）可以适当减少（互联网下建议500~1500）
--timeout 在网络不稳定时（互联网）可以适当增加
--nexthop 用于在syn扫描模式下，找不到路由网卡情况时，指定下一跳网关地址（需要是本地网卡上绑定的网关地址）
--PT ICMP不通时，使用常见端口的TCP探测主机是否存活
--sV 用于判断端口的服务（主要是探测风险比较大的服务）
--netLive 用于抽取网络内6个左右IP进行存活探测
--httpx 用于探测http服务的title等信息
--mop 用于目标组内存在防扫描防火墙的情况，单个IP扫描到开放的端口到达该值就停止对该IP扫描，避免浪费时间（建议值500）
