BIND 9: Configure Slave Zones

Today we are going over one of the fundamental aspects of administering a DNS infrastructure, that is maintaining consistency across multiple replicas.  The simplest method of accomplishing this is to have a master/slave relationship.  Essentially you have a read-write (master) copy and a read-only (slave) copy of the zone.  The slave looks to the master for information on changes. Basic BIND Configuration Here we are […]

Solaris 11: Install Bind Server

Today I am going to document the process of install BIND in Solaris 11.  I am using a Solaris 11.1 zone for this task, though nothing in this is specific to zones, and it should work on previous versions of Solaris 11.  I have done this quite a few times and it is not a very intuitive process.  As of the time of this writing […]

Using Curl to Interact with Resource Records in Rackspace Cloud DNS

In this article we will be using curl to interact with Rackspace’s Cloud DNS to manipulate resource records in zones which already exist.  For details on how to use curl against Rackspace’s Cloud DNS API please see part one in this series “Using Curl to Access Rackspace Cloud DNS” in part two I documented the creation of DNS zones “Using Curl to Interact with Zones […]

Using Curl to Interact with Zones in Rackspace Cloud DNS

In my previous post “Using Curl to Access Rackspace Cloud DNS” we documented the basics of authenticating with the Rackspace Cloud for use with the Beta DNS service they offer, as well as doing basic queries against this service.  Today we are going to focus on creating our first domain, which no doubt will offer challenges for us, since it will require the uploading of […]

Using Curl to Access Rackspace Cloud DNS

Lately I have been looking at some cloud options for my more critical services, in this I have investigated Zerigo, Route 53, and Rackspace Cloud DNS.  Currently I have been focused on Rackspace DNS, since it is still free at this point, and frankly I’d rather not spend money on anything until I understand exactly how it works.  I have no experience with using “api” […]

Using Views with BIND 9 Part 2

BIND 9 gives us the ability to run a split DNS configuration on a single server, in this article we will go over the configuration of slave servers which will transfer the zones from the master while still maintaining its views. Now before we go any further, if you do not have a working master server with views configured you will want to review part […]

Using Views with BIND 9

In almost all organizations the network infrastructure needs to be designed in such a way as to allow both internal and external name resolution authoritatively.  In most organizations this has been accomplished by having separate internal and external servers.  Clearly this way is functional and simpler, however it is also wasteful considering how little resources DNS actually requires.  BIND 9 gives us a new method […]
