Elastic IP

Explains Elastic IPs and their use in cloud networking.

ip Command

The ip command is the primary command-line tool for configuring and managing network interfaces in modern Linux systems. It is part of the iproute2 package and replaces older tools like ifconfig and route.

iptables

iptables is a user-space utility that allows a system administrator to configure the IP packet filter rules of the Linux kernel firewall, implemented as a set of Netfilter hooks. For many years, it has been the standard tool for firewalling on Linux.

Netfilter Framework

Netfilter is the underlying packet filtering framework within the Linux kernel. It is not a tool that users interact with directly, but rather a powerful infrastructure that provides a series of "hooks" into the kernel's network stack.

Networking in AWS

Overview of networking concepts within Amazon Web Services (AWS), including VPCs, Subnets, Route Tables, and Security Groups.

SNAT Gateway

Explains SNAT gateways and their role in providing outbound internet access for resources in a Virtual Private Cloud (VPC).

Understanding Network Virtualization

Network Virtualization (NV) is the process of combining hardware and software network resources into a single, software-based administrative entity. In essence, it abstracts the physical network, allowing you to create multiple isolated virtual networks on top of a single physical infrastructure.

Understanding the Networking Data Plane

In networking, devices like routers and switches have distinct logical components that handle different tasks. These are broadly categorized into three planes: the management plane, the control plane, and the data plane. Understanding these planes is crucial for designing, managing, and troubleshooting modern networks.

veth (Virtual Ethernet)

A veth (Virtual Ethernet) pair is a Linux kernel feature that creates two virtual network interfaces that are linked together. Think of it as a virtual patch cable. Packets sent out one interface of the pair are immediately received on the other interface.
