Episode 60: Network Services — DNS, DHCP, NTP, Syslog
This episode introduces four essential network services: Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), Network Time Protocol (NTP), and Syslog. DNS translates hostnames into IP addresses, DHCP automatically assigns addresses to devices, NTP synchronizes clocks across systems, and Syslog provides centralized logging. These services are critical both for exam questions and for the reliable operation of any network.
The discussion expands into practical use. DNS failures may cause websites to be unreachable, DHCP outages prevent devices from obtaining IP addresses, NTP misconfigurations lead to authentication problems, and Syslog supports security monitoring by collecting logs in one place. Troubleshooting tips are given for each, including verifying DNS resolution with nslookup, checking DHCP scope exhaustion, and monitoring NTP offsets. By mastering these services, you will be prepared to answer detailed exam questions and manage real-world network infrastructure.
