Nagios3 is an excellent monitoring engine, but the stock Nagios has some limitations in regard to dual-stack hosts. In the Nagios universe, one host is one ip address, and a secondary ipv6 address would require an extra host definition.
The Nagios packages which you are about to install have been patched to support this concept "one host = 1 ipv4 address + 1 optional ipv6 address". The mknagconf script makes it easier to maintain your Nagios installation. mknagconf takes small short, and simple definition files, parses them and generate the configuration files for Nagios. This will be explained after installing the required software.
