1. Interface Management in Linux
Linux provides a wide array of tools for managing network interfaces, monitoring connections, and configuring IP addresses, routes, and hostnames. These tools span across legacy utilities (like ifconfig from net-tools) and modern replacements (like ip from iproute2). Additionally, there are system-specific configurations and utilities such as NetworkManager and persistent interface files.
1. iproute2 Tools
iproute2 is the modern suite of networking utilities that replaces the older and now-deprecated net-tools utilities like ifconfig, netstat, route, and arp. It is included by default in nearly all modern Linux distributions.
The key utility in this suite is the ip command, used for managing:
- Network interfaces
- IP addresses
- Routing tables
- Tunnels
- Neighbors (ARP)
- Network namespaces and more
