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.
