Several Netgear router models running factory firmware have a telnet daemon that listens at the router's local LAN IP address. Administrators have a couple of ways of gaining access to a hidden command line interface (CLI) with a telnet client: Calling the routers "debug" endpoint, by simply going to the router's debug endpoint in a browser, i.e. at http://192.168.1.1/setup.cgi?todo=debug to enabl

Lots of ISPs provide their users with an IPTV service, usually done via IPv4 UDP multicasting. This document aims to explain how to make it work for most common scenarios. When a host wants to start receiving UDP multicast traffic, it needs to subscribe itself to a "UDP multicast group". Control of multicast groups is achieved with IGMP protocol. Once a host is subscribed, all the traffic for this
In the default configuration, OpenWrt bridges the wireless network to the LAN of the device. Most wireless drivers do not support bridging in client mode (see Bridged Client Mode Issues), therfore the traffic between LAN and the wireless client must be routed. The relayd package helps to implement a bridge-like behaviour with DHCP and Broadcast relaying comparable to the proprietary Broadcom WET m
This is the main Table of Hardware, listing all devices that are supported by OpenWrt.
Above we read merely about the theory of networking, about the basic ideas, about communication protocols and standards. Now, let us see, how all of this is being handled by the Linux Kernel 2.6: Everything related is found under /net/. But drivers, for the network devices, are of course found /drivers/. NOTE:
The central network configuration is located in the file /etc/config/network. This configuration file is responsible for defining switch VLANs, interface configurations and network routes. After editing and saving /etc/config/network you need to execute /etc/init.d/network reload to stop and restart the network before any changes take effect. Rebooting the router is not necessary.
The wireless UCI configuration is located in /etc/config/wireless. Learn about the entire IEEE 802.11 "wireless" subsystem. Note1: By default the wireless is OFF. You can turn it on in the /etc/config/wireless by changing disabled 1 to disabled 0 In UCI CLI you do this with: uci set wireless.@wifi-device[0].disabled=0; uci commit wireless; wifi Note2: If your device contains multiple radios (e.g.

Once you have obtained Basic USB support, you may want to connect a USB storage device to your router, for example a USB stick, a USB hard disk, etc. This article will tell you the steps and requirements to do this. Note that this article is mainly about adding external space in addition to the internal flash usage. Moving the root-fs to an external storage space is described in the article extroo

Unlike many other distributions for routers, OpenWrt is built from the ground up to be a full-featured, easily modifiable operating system for embedded devices. In practice, this means that you can have all the features you need with none of the bloat, powered by a modern Linux kernel.
