downtimed is a program that monitors operating system downtime, uptime, shutdowns, and crashes and records such events. At OS startup it logs information about previous downtime. It then periodically updates a time stamp file on the disk, which is used to determine the approximate time when the system was last up and running. During a graceful system shutdown, it records a time stamp in another file. The downtimes(1) command line tool can be used to inspect records of past downtime.
RemoteBox is a graphical tool which lets you administer guests or virtual machines running under VirtualBox on a remote server or even your local machine if desired. You may, for example, have a root server on the Internet, a server at home, or a server at work running VirtualBox but want to have the convenience of managing the guests easily from your local machine. The virtual machines run in headless mode, which means you don't need an active graphical display on the server but you can still connect and view the displays of the guests. The goal of RemoteBox is to provide a GUI that should be familiar to VirtualBox users while allowing them to administer a remote installation of VirtualBox. It does this via the VirtualBox API and SOAP interface, which are exposed when running the VirtualBox Web service. You can also use RemoteBox simply as an alternative interface for managing VirtualBox on your local machine.
agentsmith is a daemon that continuously monitors a log file for break-in attempts by remote hosts. Upon detection of a break-in attempt, it launches a user defined script or application, which can do virtually anything from sending mail messages to whatever else you might think of. The criteria for what is considered a break-in attempt can be configured by means of a regular expression.
Sentinella is a desktop application that monitors your system activity and, when a condition is met, takes the action that you've chosen. While monitoring your CPU, memory, hard drive, and network usage, Sentinella can be programmed to take specific actions when setpoints for utilization or time are met. It can power off, reboot, or hibernate your system, kill an active process, throw an alarm, or execute any command. Sentinella integrates perfectly with the main desktop enviroments (KDE, GNOME, XFCE, and others) and works under many Unix systems.
cpuid.c is a very simple C abstraction that provides an interface to common cpuid feature flags. It can be useful when implementing dynamic CPU feature dispatch that relies on optional processor feature extensions or basic processor-specific variables. This package is meant to be a very simple feature detection interface that you can easily integrate into your project. It is not meant to be complex and it is geared for projects implementing dynamic CPU feature dispatch.
