DNSmonitor is a very simple yet effective DNS monitoring utility, very useful in debugging what happens on DNS level on your hosts and/or your company. DNSmonitor can help you in looking at the underlying mechanics of what happens at DNS request/response level by providing you basic informations on the request and response objects.
DNSmonitor uses pcap and is able to listen silently to the connetions, without need to set-up proxies or complicate environments.
For the impatient, please install required libs with sudo gem install term-ansicolor dnsruby pcap.
To run the script sudo ruby DNSmontor.rb. Superuser is needed for Pcap integration. Your screen will show you something in the line of the following paragraph:
