DNS Training Description:
Reliable and robust operation of the DNS hierarchy - from the root servers to an individual domain name server - is critical to all Internet operations. The course covers the configuration and operation of DNS systems used for a variety of purposes from high availability Zone Masters and Slaves running mission critical sites to caching servers used to speed up Internet access. While the primary focus of the course is BIND other DNS software will be discussed. BIND supports Linux, BSD and Windows platforms - installation procedures for each platform are covered.
Students will learn the theory behind the DNS hierarchy, the DNS protocol, forward and reverse mapping zone files. The major Zone file Resource Records (SOA, NS, MX, CNAME, A, PTR, TXT, SRV and NAPTR) are described and explained in detail. A number of DNS types are introduced - including Master/Slave, Caching Only, Authoritative Only, Forwarding and Stealth - and the detailed zone files and BIND configuration files (named.conf) to control operational behavior are presented. Dynamic DNS, (DDNS), integration with DHCP, Zone Transfer, Diagnostic tools and simple security models are also covered. The course includes a number of hands on configuration exercises.
The primary focus of the course is BIND which is available on Linux, UNIX and Windows platforms. The course is offered with Linux (Fedora Core), FreeBSD or Windows 2003 as the platform for all exercises.
