This is a wiki about OpenWrt.
With the release of the Linux sources for the Linksys WRT54G/GS series of wireless routers came a number of modified firmwares. OpenWrt, instead of starting with Linksys sources, started with a clean slate. Piece by piece, software was added to bring the functionality back to that of stock firmware. OpenWrt employs a writable filesystem. The device is turned into a mini Linux PC with OpenWrt, providing most traditional Linux commands and a package management system.
A similar project existed for the Linksys NSLU2-Linux network-attached storage interface; the two are independent, although Optware packages are shared between both.
