Arp

Retrieve the content of the ARP cache

Add this line to your application's Gemfile:

gem 'arp'

And then execute:

$ bundle

Or install it yourself as:

$ gem install arp

  cache = Arp::Cache.new
  cache.each do |entry|
    puts entry.ip             # => "192.168.124.2"
    puts entry.hw_type        # => "0x1"
    puts entry.flags          # => "0x2" 
    puts entry.hw_address     # => "00:50:56:e9:27:c7" 
    puts entry.mask           # => "*"
    puts entry.device         # => "eth0" 
  end

Currently works only on Linux. Tested on Ubuntu 12.04.
