OpenWrt is described as a Linux distribution for embedded devices.
Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developer, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

OpenWrt supports Cavium Octeon SoC
Since changeset 15640 OpenWrt now supports the Cavium Octeon SoC, thanks to the recent work of David Daney.
CommentsOpenWrt & "Botnet Worm Targets DSL Modems and Routers"
Just a little clarification regarding the article [1] recently posted on /. about a stealth router-based botnet [2]:
- OpenWrt blocks any open port from the WAN side by default ;
- OpenWrt does not provide a "default" password ;
- Any device with weak passwords that can run the binary is vulnerable ;
- As far as we know, there is no core vulnerability in OpenWrt requiring a security fix.
If you opened SSH on the WAN port, ensure you use a strong password for your "root" account, or disable password authentication and rely on key based authentication.
Yours truly,
