DNS and BIND: Setting Up, Managing and Securing Your DNS Server

• Knowledge of the Unix/Linux command line (shell).
• Knowledge of Unix/Linux-based TCP/IP networks.

Audience

• Network technicians
• Network designers
• System administrators

DNS (domain name system) is the "phone book" of the internet, providing a directory of computer names and their IP addresses. BIND is the most common Linux implementation of DNS. When you open a website or send and receive an email, a DNS server somewhere is quietly addressing your message to its intended recipient.

In this instructor-led, live training, participants will learn the critical features of DNS while carrying out exercises in the setup and configuration of a BIND DNS server on Linux. The course starts with a refresher on key networking principles, then digs into hands-on practice with setup and configuration. Steadily, the discussion and practices move towards more complex topics such as security, availability, debugging and troubleshooting.

Format of the Course

• Part lecture, part discussion, heavy hands-on practice and implementation, occasional quizing to measure progress
