Simple Port Scanner on LAN

This scanner is only available on Linux, do not try to run it on Windows and WSL cause the latter do not support physical network adapter.

Not recommended on other Unix distributions, they may have different definitions for protocol handlers.

Building

1. make

$ make

2. clean files

$ make clean

Usage

1. Scan all hosts on LAN, it uses fping to search hosts in LAN, search results is saved in hosts.log:

$ sudo ./scanner

2. Scan specific host with ip address:

$ sudo ./scanner -i [ip address]
$ sudo ./scanner -i 192.168.1.102

3. Scan specific hosts with ip address within [start port, end port]:

$ sudo ./scanner -i [ip address] [start port] [end port]
$ sudo ./scanner -i 192.168.1.102 251 996
