Ethernet, ARP and RARP
Linux serves as a prevalent OS choice for networking due to its robust, customizable, and open-source nature. Understanding networking in Linux involves comprehending various protocols and tools. Three crucial components of this landscape include Ethernet, ARP (Address Resolution Protocol), and RARP (Reverse Address Resolution Protocol).
- Ethernet: It’s the most widely installed LAN (Local Area Network) technology, allowing devices to communicate within a local area network.
- ARP: As per its name, it provides address resolution, translating IP addresses into MAC (Media Access Control) addresses, facilitating more direct network communication.
- RARP: It is the Reverse Address Resolution Protocol, working in the opposite way to ARP. It converts MAC addresses into IP addresses, which is useful in scenarios when a computer knows its MAC address but needs to find out its IP address.
Knowledge of these components is indispensable in diagnosing and managing networking issues in Linux.
