Session - 101 | DNS Server Setup on Linux RHEL 10 | Full Theory to Hands-On BIND Configuration

Session 101: DNS Server Setup on Linux RHEL 10 | Full Theory to Hands-On BIND Configuration Tutorial Dive deep into DNS (Domain Name System) configuration on Linux RHEL 10! Whether you're a beginner sysadmin or leveling up your networking skills, this comprehensive tutorial covers everything from DNS fundamentals to setting up a primary authoritative DNS server using BIND. We'll break down the theory behind how DNS resolves names to IPs globally, then walk through a step-by-step lab setup on RHEL 10—complete with forward/reverse zones, zone files, testing, and troubleshooting. Why Watch This? Understand DNS hierarchy, zones, record types (A, PTR, MX, SOA, etc.), and query types (recursive vs. iterative). Hands-on lab: Install BIND, configure named.conf, create zone files, set permissions, firewall rules, and test with nslookup/dig. Perfect for RHCSA/RHCE prep or real-world server management.
