In the field of network management on Linux systems, there is a classic toolkit that has been refined over many years — net-tools. As a core foundational component of the Linux operating system’s NET-3 network distribution, it has long been an indispensable tool for network configuration and monitoring for operations engineers, network administrators, and technical enthusiasts. This open-source toolkit occupies a crucial position in the Linux network ecosystem due to its stable and reliable performance and comprehensive functionality.Basic network configuration tools: <pre class="language-plaintext">ifconfig</pre> is the most commonly used network interface configuration tool, allowing for easy enabling/disabling of network interfaces, IP address configuration, and subnet mask settings. <pre class="language-plaintext">hostname</pre> focuses on viewing and modifying the hostname, serving as a core tool for system identification configuration.Routing and address resolution tools: The <pre class="language-plaintext">route</pre> tool can directly manipulate the system routing table, supporting the addition, deletion, and viewing of static routes, which is key to building a local area network routing architecture. <pre class="language-plaintext">arp</pre> and <pre class="language-plaintext">rarp</pre> are used to manage ARP cache and reverse ARP resolution, effectively solving address mapping issues within the local area network.Network monitoring and statistics tools: <pre class="language-plaintext">netstat</pre> is known as the “Swiss Army knife” of network status monitoring, providing a comprehensive display of the system’s network connection status, routing table details, interface data statistics, and other key information, which is essential for troubleshooting.
