Linux networking refers to the ability of Linux-based systems to communicate with other systems over a network. Networking in Linux involves the use of protocols, services, and tools to enable communication between devices, share resources, and provide access to the internet. Linux networking can be used in a variety of settings, including home,enterprise, and cloud computing environments.
Network interfaces in Linux refer to the physical or virtual connections that enable communication between the Linux system and other devices on a network. Network interfaces can be Ethernet ports, wireless adapters, or virtual interfaces created bysoftware.
To monitor network traffic in Linux, there are various command-line tools available such as:
- tcpdump: This command-line tool is used to capture network packets and display them on the console. It can be used to filter packets based on various parameters such as source/destination IP address, port number, and protocol type.
- wireshark: Wireshark is a graphical network protocol analyzer that allows network administrators to capture and analyze network traffic. It can capture and display network packets in real-time and can be used to filter and analyze packets based on various parameters.
- iftop: iftop is a command-line tool that displays network traffic in real-time. It canbe used to monitor network traffic on a per-interface basis and can display traffic statistics based on source/destination IP addresses, ports, and protocols.
