Networking

This site covers Linux networking specific topics. It does not cover general networking questions, these are covered under the more general Wikipedia Computer Networks. See the External Links section for other useful resources.

net-tools

Overview

A collection of programs that form the base set of the NET-3 networking distribution for the Linux operating system. This package includes arp(8), hostname(1), ifconfig(8), ipmaddr, iptunnel, mii-tool(8), nameif(8), netstat(8), plipconfig(8), rarp(8), route(8) and slattach(8).

Please refer to the Ethernet page for more up to date information. This page is ancient and some love could be used to organize this information a little better under the ethernet section

This information is based off of personal experience and/or information gleaned from the web and mailing lists. It is not necessarily 100% accurate. Corrections are welcome.

bridge_stp

The Spanning Tree Protocol (STP) is used to allow multiple bridges to work together. Each bridge communicates with other bridges to discover how they are interconnected. This information is then used to eliminate cycles, and provide optimal routing of packets. STP also provides fault tolerance, because it will recompute the topology if a bridge or port fails.

motherboards

This page has heresay or limited information and may needs a more analytic basis

Provide a listing of motherboards and how well they are supported.
If work-arounds are needed, for example, disabling ACPI, or tweaking the BIOS, that information is welcome here.

ethtool

ethtool is a Linux net driver diagnostic and tuning tool for the Linux 2.4.x (or later) series of kernels. Obtain information and diagnostics related to media, link status, driver version, PCI (or other) bus location, and more.

Load balancing

For example you have 2 links to ISP, one is 64Kbit and another is metered (you pay for traffic) much higher speed.

Latency of links must be very similar, otherwise in this example, packets from one session can come in different order to final destination!

I think the FAQ should be its own page linked to from the main page. Like this FAQ -Jon

Given the amount of info on this wiki I'm not sure that this is a good idea as it could easily get overwhelmed. However we can do it and refactor later if it gets too big. For example DCCP already has an FAQ. --Imcdnzl | DCCP 19:24, 10 May 2006 (PDT)

Linux LLC Stack Origins

The stack present on the Linux kernel was originally contributed by Procom Inc, that released a combined NetBEUI + LLC stack developed for Linux 2.0.36.

networkmanager

NetworkManager is designed to be fully automatic and "Just Work" without intervention, but friendly desktop applications allow users to control the state of the network if they desire. NetworkManager keeps a list of all available network devices, and updates that list when you insert or remove new network cards, dock your laptop, etc. Using this list, NetworkManager determines the best device to use for the computer's network connection.
