Originally created by Power BV as a commercial product, it was later opened up and licensed under the GPL.Because of scope constraints and the well-documented nature of the project, I’m sure you will be able to add secondary and tertiary servers as needed.For information on configuring with a BIND back end (i.e., using BIND configuration files), please see my previous article in ADMIN Online on Power DNS with BIND back end.Install LAMP The easiest way to install LAMP stack in Ubuntu is through tasksel or by using apt-get install lamp-server.Run tasksel from terminal and select LAMP server by pressing space-bar and then select “OK”.Authoritative domain servers are of two types: primary and secondary. Sometimes called a master server, this is the original and definitive source for all zone records for a domain. Often called a slave server, this server is an identical replica used to provide redundancy and high availability.
It goes without saying that providing additional redundancy is vital to a service as critical as DNS. The Power DNS Recursor, on the other hand, simply provides caching or a standalone recursive resolver for clients accessing your network or the greater Internet (i.e., it is your first line of DNS for client machines).
Thankfully, we no longer live in the early days of the Arpanet (precursor to today’s Internet), where we had to transfer large host files from node to node.
Its compact codebase and focus on security, scalability, and reliability make Power DNS (PDNS) a great nameserver choice; it is jam packed with features that would impress any network or sys admin (Table 1).
Recall that it isn’t authoritative but simply provides query resolution to network client resolvers (client-side portion used to perform DNS queries) on your local machine. The supermaster feature set in Power DNS allows you to automate the provisioning of slaves.
Superslaves can configure themselves automatically as a slave for a zone when they receive notification from a known supermaster.
An authoritative name server is just what it sounds like: It is the original and conclusive source of DNS zone information for a particular domain.
