MN Viewer (Mobile Network Viewer) is a lightweight framework designed for system administrators who would like to be able to monitor many aspects of their network from their mobile phone. It allows for very simple expansion using simple PHP plugins. It is designed to integrate with other monitoring tools such as Cacti.
hwmultd is a daemon which, when run in server mode, periodically polls some hardware device, like an entropy source, and multicasts that information. Alternatively, hwmultd can run in client mode, listening for multicasted information and then acting accordingly, like adding gathered entropy to the local pool. Its simple plugin system allows hwmultd to be agnostic with respect to the hardware, which could include devices such as temperature probes or time sources.
