OpenWrt is an operating system (in particular, an embedded operating system) based on the Linux kernel, primarily used on embedded devices to route network traffic. The main components are the Linux kernel, util-linux, uClibc or musl, and BusyBox. All components have been optimized for size, to be small enough for fitting into the limited storage and memory available in home routers. OpenWrt is configured using a command-line interface (ash shell), or a web interface (LuCI). There are about 3500 optional software packages available for installation via the opkg package management system. OpenWrt can run on various types of devices, including CPE routers, residential gateways, smartphones (e.g. Neo FreeRunner), pocket computers (e.g. Ben NanoNote), and laptops (e.g. One Laptop per Child (OLPC)). It is also possible to run OpenWrt on ordinary computers, which are most commonly based on the x86 architecture. Many patches from the OpenWrt's codebase have been included upstream in the Linux kernel mainline. == History == The project came into being because Linksys built the firmware for their WRT54G wireless router from publicly available code licensed under the GPL.〔(Linksys WRT54G and the GPL ) on lkml (7 Jun 2003)〕 Under the terms of that license, Linksys was required to make the source code of its modified version available under the same license,〔(The Open Source WRT54G Story ) By Aaron Weiss (November 08, 2005)〕〔(Linksys Releases GPLed Code for WRT54G ) on slashdot (July 2003)〕 which in turn enabled independent developers to create additional derivative versions. Support was originally limited to the WRT54G series, but has since been expanded to include many other chipsets, manufacturers and device types, including Plug Computers and Openmoko mobile phones. Using this code as a base and later as a reference, developers created a Linux distribution that offers many features not previously found in consumer-level routers. Some features formerly required proprietary software. Before the introduction of OpenWrt 8.09, using Linux 2.6.25 and the b43 kernel module, WLAN for many Broadcom-based routers was only available through the proprietary wl.o module that was also provided for Linux kernel version 2.4.x only.The code names of OpenWrt branches are named after alcoholic beverages, usually including their recipes in the MOTD as well, cf. White Russian, Kamikaze, Backfire, Attitude Adjustment, Barrier Breaker. The bleeding edge development trunk was confusingly also called Kamikaze until February 2011 but with r25514 it was renamed as "Attitude Adjustment" and is now being constantly renamed to the next stable name. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「OpenWrt」の詳細全文を読む スポンサード リンク
