Intro to Network Commands
Welcome to this lesson on essential Linux networking commands! Understanding these tools is crucial for diagnosing network issues and viewing your system's network configuration.
We'll explore ping for checking connectivity, ip for comprehensive network interface management, and netstat for viewing active connections.
What is Ping?
The ping command is a fundamental tool used to test the reachability of a host on an Internet Protocol (IP) network. It sends small data packets to a target and waits for a response.
- Purpose: Check if a remote computer or server is online.
- Measurement: Calculates the Round-Trip Time (RTT) for packets to reach the host and return.
- Analogy: Think of it like a sonar pulse for your network!
