A golang scanner
Project description
介绍
gscan
最初是为项目gosam提供基础扫描支持的。后来独立出来成为一个类似 nmap
的扫描工具,目前正在努力加强和完善中,项目很期待其他开发者的加入。也欢迎您下载发布包来体验它,帮我们测试并反馈问题给我们。
特性
- ARP scan
- ICMP scan
- TCP port scan
- Domain support
- Random port support
- UDP port scan
- Service discovery
- Vulnerability discovery
- Adaptive binary overflow
使用
从发布包里下载的对应系统和架构的可执行文件 gscan
。

简单例子
ARP 扫描
对本地的整个局域网进行 arp 扫描
$ gscan arp -a
192.168.50.179 00:15:5d:fa:d7:e7 Microsoft Corporation
192.168.48.1 00:15:5d:ab:10:3a Microsoft Corporation
Cost: 6.514218807s
对指定 IP 进行 arp 扫描
$ gscan arp -h 192.168.50.179
192.168.50.179 00:15:5d:fa:d7:e7 Microsoft Corporation
Cost: 6.500702247s
注意:默认超时为6500毫秒,可以使用
-T
进行指定,单位为毫秒。
ICMP 扫描
单IP or 网段 主机存活探测
$ gscan icmp -h 192.168.1.1/24
IP Status
192.168.1.1 Alive
Cost: 4.009240208s
多目标 存活探测
$ gscan icmp -h 192.168.1.1 -h 192.168.2.2
IP Status
192.168.1.1 Alive
192.168.2.2 Alive
Cost: 4.002214791s
TCP Port 扫描
对一个 IP 进行全端口探测
$ gscan port -h 192.168.48.1 -p 0-65535
IP PORT TYPE STATE
192.168.48.1 135(epmap) tcp open
192.168.48.1 5091 tcp open
192.168.48.1 7680(pando-pub) tcp open
192.168.48.1 5040 tcp open
192.168.48.1 5357(wsdapi) tcp open
192.168.48.1 2179(vmrdp) tcp open
192.168.48.1 10808 tcp open
192.168.48.1 10809(nbd) tcp open
Cost: 6.00483283s
对一个 IP 进行全端口探测,结合 ARP 扫描结果
$ gscan port -h 192.168.48.1 -p 0-65535 -A

192.168.48.1 00:15:5d:ab:10:3a Microsoft Corporation 10809(nbd) tcp open
192.168.48.1 00:15:5d:ab:10:3a Microsoft Corporation 7680(pando-pub) tcp open
192.168.48.1 00:15:5d:ab:10:3a Microsoft Corporation 10808 tcp open
Cost: 9.013501996s
使用全连接模式对一个 IP 进行全端口探测
$ gscan port -h 192.168.48.1 -p 0-65535 -Af
IP MAC VENDOR PORT TYPE STATE
192.168.48.1 00:15:5d:ab:10:3a Microsoft Corporation 10808 tcp open
192.168.48.1 00:15:5d:ab:10:3a Microsoft Corporation 7680(pando-pub) tcp open
192.168.48.1 00:15:5d:ab:10:3a Microsoft Corporation 2179(vmrdp) tcp open

192.168.48.1 00:15:5d:ab:10:3a Microsoft Corporation 5357(wsdapi) tcp open
Cost: 9.01656839s
注意:
gscan
使用的是gopacket
模拟的全连接,所以使用-f
参数时应该开启本地的防火墙,防止本机系统自动rst
连接导致全连接扫描失败。
开发
从源码构建
环境准备
debain/ubuntu
apt install docker
darwin(MacOS)
brew install libpcap-dev golang git
拉取源码
git clone https://github.com/LanXuage/gscan.git
