	DNS Training Registration System



	There are no current DNS courses - please come back later
	Courses are usually held twice a year, around i-Week time (September) and at the beginning of the year (late January to early February). Registration is open a month or so before each course. The courses are usually held in Johannesburg (Midrand) and Cape Town. There is an Intro course and an Advance course which alternate in these locations. The Intro course is the first course of any training session, followed by the Advance Course.

	DNS Training Application Form The training course starts at 09:00 and finishes at 17:00. Documentation, refreshments and lunch will be provided. General information The DNS courses are presented by Johan Ihren and Mark Elkins. The Lab exercises are conducted by using Laptops running X Windows. The student uses the Laptop to connect via SSH (Secure SHell) to their (virtual) DNS Servers which are running on a BSD (Unix) system. Students must therefore bring their own Laptops and perhaps a USB memory sticks to keep copies of their work. DNS Introduction Training Course Outline Description This course covers the fundamentals of DNS and all the important terminology is covered. In the course you will learn how to design DNS structure to achieve scalability and high availability. You will learn how to install and configure DNS name servers and you will get an understanding for how zones and domains are delegated, administratively as well as in technical solutions. Target audience The target audience for this course is networking people, network and DNS administrators as well as managers, people working with IT strategy, consultants, security people and others that need an understanding of DNS and DNS role on the Internet. Pre-requisites This course requires fundamental knowledge about the Internet and TCP/IP. Experience with a Unix/Linux text editor such as vi or emacs is very helpful as is an understanding of the Unix/Linux file system. Duration: usually 4 days Course Outline DNS Introduction The Internet before DNS Introduction to the concept of a Resource Record Caching, TTL and scalability Delegation, the key to scalability Name server roles Root name servers Resolvers Detailed message exchange walk-through Lab exercise: Compilation and installation of DNS software Name server implementations Debugging tools Fundamental types of Resource Records The named.conf configuration file Lab exercise: Configuration of caching only resolver Private addresses, RFC1918 Name server terminology Zones: the administrative entity of DNS Lab exercise: Configuration of authoritativ server Lab exercise: Delegation of sub-domain IPv6 and DNS Lab exercise: Configuration and delegation of a reverse zone. Lab exercise: IPv6 TSIG Lab exercise: TSIG Summary DNS Advanced Training Course Outline Description The advanced course covers more complex DNS topics, such as DNS in combination with Firewalls and "Split-DNS". A complete treatment of DNSSEC (signing and authentication of DNS data) as well as TSIG (DNS Transaction Signatures, EDNS(0) and Views.
