9. How to become a bigger time DNS admin.
DNS can be intimidating at first. What files do I modify? What do I put in them? How does it apply to Solaris, specifically? If you're used to another operating system, Solaris, like any new platform - might not be immediately obvious, as there are a few pecularities you should be aware of. This article will discuss DNS related issues under Solaris, using version 7 as the reference platform and the stock Sun version of BIND.
Further down, BIND v9.1.0 will be discussed as an upgrade to the stock version. You should definately consider upgrading this way, as there are several security holes that can compromise root on your box with the stock BIND v8.1.2 that ships with Solaris 7.
A few key terms to understand are needed before we dive in. BIND refers to the software that you will be interacting with. What it does is provide a domain name server (DNS) that translates hostnames into valid (hopefully) IP addresses. When it is running on your system, you will often see a process called named or in.named.
It's really quite simple to get going and keep DNS maintained. We won't be getting too involved in complex DNS setups, but will illustrate all the basics needed to get most jobs done and get you up and running in the least amount of time.
There are several ways to provide a name resolution to your local machine and it's users or to your entire office - or even the Internet in general. Among the possibilities are:
- Local resolution of local machines outside of BIND
- Internal use only name server
- Completely external name resolution
- External name resolution with local caching
- Being the authoritative DNS server for your domain(s)
Depending on these needs determines how you will be setting up DNS and which files are to be modified and maintained. You should decide ahead of time what your needs are, but keep in mind that you can always modify this behavior at a later time quite readily.

Files needed on secondary nameserver
Note that the locations and names of these files can vary quite a bit, but this naming scheme will work fine.
