Focused on sharing practical Linux technology content, covering Linux fundamentals, applications, tools, as well as databases, operating systems, network security, and other technical knowledge.
This article reviews ten open‑source Linux network monitoring utilities—iftop, vnstat, iptraf, Monitorix, dstat, bwm‑ng, ibmonitor, htop, arpwatch, and Wireshark—detailing their features, typical use cases, installation notes, and how each helps administrators track bandwidth, connections, and potential issues via the command line.
This comprehensive tutorial walks through the Linux networking stack—from basic concepts, physical and data‑link layers, and addressing schemes to routing protocols, TCP/UDP transport mechanisms, application‑layer services like DNS and HTTP, and security fundamentals—providing clear explanations, step‑by‑step processes, formulas, and visual diagrams to help readers understand how each layer works and interacts.
Nali is a Go‑rewritten open‑source terminal tool that lets you query IPv4/IPv6 geolocation and CDN provider information offline using multiple databases, supports pipe processing and interactive mode, and can be installed from source or pre‑compiled binaries with configurable environment variables.
The article compiles several Zhihu contributors' explanations—covering historical Windows dominance, IIS limitations, cost differences, ecosystem strength, container support, and open‑source politics—to show why Linux has become the default operating system for modern servers.
Ubuntu, backed by Canonical, has become the most representative Linux distribution, widely used across desktops, servers, IoT, AI labs, and education due to its user‑friendly interface, extensive software ecosystem, and stable LTS releases, though it faces criticism for Snap packaging and commercial bloat.
This article provides an exhaustive reference of Linux command‑line utilities, covering basic system information, file and directory management, searching, mounting, disk usage, user and group administration, permissions, special attributes, archiving, compression, backup, networking, VIM editing, and RPM package management, complete with concrete examples and command syntax for each task.
This comprehensive tutorial walks through the Linux networking stack—from basic concepts and physical layer signaling to data link, network, transport, and application layers—detailing protocols, addressing, routing, error detection, and security mechanisms with clear diagrams and step‑by‑step explanations.
This guide walks Linux administrators through nine core networking utilities—ip, netstat, nmap, traceroute, tcpdump, ssh, wget, netplan, and nmtui—explaining their purpose, key options, and example commands to configure interfaces, inspect routes, capture packets, and manage remote connections.
This article explains what a router is, how routing tables guide packet forwarding, the differences between direct, static, and dynamic routes, three‑layer addressing, and the longest‑prefix‑match principle that determines the optimal path for network traffic.
This guide walks through Makefile fundamentals—including targets, dependencies, commands, variables, pattern rules, automatic variables, functions, conditional statements, includes, custom functions, multi‑target handling, phony targets, and debugging techniques—providing concrete examples and code snippets that enable readers to build and manage both small and large projects efficiently.
