Linux Networking
Linux Networking refers to the suite of tools, protocols, and configurations used to manage network connectivity, routing, and communication on Linux-based systems. It encompasses everything from basic IP address assignment and firewall rules to advanced topics like network namespaces, packet filtering, and virtual networking. This skill is essential for system administrators, DevOps engineers, and developers working in networked environments.
Developers should learn Linux Networking to effectively deploy, manage, and troubleshoot applications in cloud, containerized, or on-premises environments where Linux is prevalent. Specific use cases include configuring firewalls with iptables or nftables, setting up VPNs, managing Docker or Kubernetes networking, and optimizing network performance for web servers or databases.
