Xnetintf is an X Windows application that manages network interfaces. The current interface state is depicted through a series of bitmaps, and a mouse click in the window initiates a state transition. Xnetintf uses a per-interface configuration file to supply commands that check and toggle state, as well as a program to run after the state change completes. A command line interface is also supported.
xps dynamically displays in an X Window the Unix processes as a tree or forest, the roots on the left and the leaf processes on the right. The status of each process (running, sleeping, stopped, etc.) can be indicated by a color. Different users appear as different colors. Process selection can be made per user, all users or through a regular expression pattern. A process can be selected to show ps information or to send the process a signal.
xsysguard is a resource-friendly system monitor based on Imlib2. The main features include a powerful configuration file format, full alpha channel support, configurable widgets, and many data sources implemented as modules. For example, the daemon module allows you to monitor remote machines, and the file module can parse files with scanf or regular expressions.
