Python Network Scanner

Live host (in LAN) discovery, their IPv4 and MAC addresses and open TCP ports

This is proof of concept, it's not optimized

Install requirements

$ pip install -r requirements.txt

Usage

usage: netscan.py [-h] [-p PORT1,PORT2,...] [-r] [-s] [--noverbose] IP/PREFIX_LENGTH

Network Scanner - discovering live hosts and their open ports

positional arguments:
  IP/PREFIX_LENGTH      Network to scan in CIDR format (or single IPv4 address)

optional arguments:
  -h, --help            show this help message and exit
  -p PORT1,PORT2,..., --ports PORT1,PORT2,...
                        Port numbers (comma separated). If you want to scan range, use -r/--range
  -r, --range           Scan port range. If enabled, -p/--ports option should take arguments like this: FIRST-LAST
  -s, --syn             Use SYN scan
  --noverbose           Disable verbosing

examples:
$ python netscan.py -p 22,53,80,443 --syn 192.168.1.0/24
$ python netscan.py -p 1-1000 --range --syn 192.168.1.0/24

Remember to have the oui.txt file in the same directory as the script.
