Description
Netenum comes as part of the IRPas suite of tools. It is a very basic ping sweeper and enumeration tool that can give a tester a very quick list of hosts that are up.
Installation
Install netenum via irpas package:
$ sudo apt-get install irpas
Then optionally create a symbolic link in your /pentest/ directory:
$ mkdir -p /pentest/enumeration/netenum/ $ ln -s /usr/sbin/netenum /pentest/enumeration/netenum/netenum
Usage
Basic syntax
$ sudo netenum <destination> [timeout] [verbosity]
Options
- timeout
- defines the maximum time (in seconds) to wait for a response before considering that the target is down
- verbosity
- Define the verbosity level (from 0 to 3)
- Default value: 0 (recommended value)
Example
Netenum enables to identify live hosts on the network:
$ sudo netenum 192.168.100.0/24 5 | sort 192.168.100.1 192.168.100.11 192.168.100.13 192.168.100.18 192.168.100.50 192.168.100.51
Note
In the example, we send the output to sort in order to order the IP addresses.
