This tutorial walks through 15 essential Linux networking commands—ping, ip, ip route, ss, netstat, tcpdump, curl, wget, traceroute, dig, nmap, nc, ethtool, nmcli, and iperf3—explaining their syntax, typical use‑cases, and how they help diagnose connectivity, routing, port, and performance issues.
This guide explains the fundamentals of Linux bridges, their role in linking network interfaces, and provides step‑by‑step instructions for creating, configuring, and managing bridges using brctl, NetworkManager (nmcli), and iproute2 commands across various distributions.
This guide explains Linux bridge concepts, how bridges work at the data‑link layer, and provides step‑by‑step commands for creating, configuring, and managing bridges using brctl, NetworkManager, iproute2, and persistent configuration files on CentOS and Ubuntu systems, including STP setup.
This guide explains the powerful Linux ip command, covering its basic syntax, how to view and configure network interfaces, manage IP addresses, routes, VLANs, and ARP entries, and provides practical examples for everyday system administration tasks.
This guide explains the concept and operation of Linux network bridges, details how bridge members interact, describes data flow and IP handling, and provides step‑by‑step instructions for creating and managing bridges using brctl, nmcli, ip commands, and distribution‑specific configuration files, including STP setup.
This guide explains how to configure additional routing rules for a second network interface on Linux by creating a new policy routing table, adding specific routes and rules with iproute2 commands, and verifying that traffic uses the intended NIC.
This guide explains how to configure additional routing tables and policy‑based routes on a Linux server with two network interfaces, covering IP address inspection, routing table edits, ip rule commands, and persistence across reboots.
Learn how to use the iproute2 suite on Linux to view, configure, and troubleshoot network interfaces, addresses, routes, and ARP entries, replacing legacy net‑tools commands with consistent, powerful commands like ip addr, ip link, and ip route, demonstrated on Ubuntu 12.04.
This guide explains how to view IP addresses on Windows and Linux, compares commands like ipconfig, ifconfig, and ip addr, and delves into networking fundamentals such as CIDR, public vs private IP ranges, MAC addresses, and interface flags.
This tutorial walks through the fundamentals of Linux bridge devices, showing how to create a bridge with iproute2, connect it to veth pairs, assign IP addresses, attach a physical NIC, and apply the setup in virtual‑machine and Docker environments while explaining common pitfalls and networking behavior.
This guide walks you through Linux network virtualization fundamentals, explaining how to create and manage Network Namespaces, configure veth pairs and bridges, and enable communication between isolated namespaces using iproute2 commands, complete with practical command examples and troubleshooting tips.
This guide explains how to install iproute2, use the ip command to configure IP addresses, manage routing tables, monitor network statistics, handle ARP entries, and troubleshoot Linux networking, providing clear examples and command-line snippets for system administrators.
