Installation

NMAP

This gem is based on nmap. So you need to install nmap before and ensure it is available via command line (added to PATH environment variable).

To check if you have installed nmap correctly, run the following command on a terminal

nmap --version

and you should get some version information. After, you are ready to install the ruby gem.

Gem

Add this line to your application's Gemfile:

gem 'lan_scanner'

And then execute:

$ bundle install

Or install it yourself by:

$ gem install lan_scanner
