Ubuntu bind slave not updating

For the visitors of your servers, any DNS server is the same and there is no difference between masters or slaves, so you should define one master and as many slaves as you want (anything between 2 to 4 slaves is OK).

allow-notify applies to slave zones only and defines a match list, for example, IP address(es) that are allowed to NOTIFY this server and implicitly update the zone in addition to those hosts defined in the masters option for the zone.

Most importantly, it translates domain names meaningful to humans into the numerical identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide.

The Domain Name System makes it possible to assign domain names to groups of Internet resources and users in a meaningful way, independent of each entity's physical location.

Users take advantage of this when they recite meaningful Uniform Resource Locators (URLs) and e-mail addresses without having to know how the computer actually locates them.

BIND (pronounced /ˈbaɪnd/), or named (/ˈneɪmdiː/), was as of 2004 the most commonly used Domain Name System (DNS) server on the Internet, and still proclaims itself to be so.

But for sure it is in your software repository, I will focus this tutorial on Debian, Arch Linux and Slackware, of course Ubuntu and other Debian derivatives are also covered.

Let's keep an alphabetical order for the distributions covered here: Note: You may want to save a copy of every file you will edit before doing so, in case you screw things up.

Other important features of BIND 9 include: TSIG, DNS notify, nsupdate, IPv6, rndc flush (remote name daemon control), views, multiprocessor support, and an improved portability architecture.

The first thing you may want to check is where your zone files are stored, and that is not the same for each distribution, but you can change that if you want.

Where your zone files are, is defined in the options section of the // This is the primary configuration file for the BIND DNS server named. for information on the // structure of BIND configuration files in Debian, *BEFORE* you customize // this configuration file. ( 2010122801 ; serial 7200 ; refresh (2 hous) 7200 ; retry (2 hours) 2419200 ; expire (5 weeks 6 days 16 hours) 86400 ; minimum (1 day) ) $TTL 14400 ; 4 hours NS scz.

On Unix-like operating systems it is the de facto standard.

Originally written by four graduate students at the Computer Systems Research Group at the University of California, Berkeley (UCB), the name originates as an acronym from Berkeley Internet Name Domain.

The default behaviour is to allow zone updates only from the masters IP(s).
