Networkled is a small system tray utility which gives a graphical indication of the received and transmitted traffic. It relies on the proc file system and more specifically on the existence of the file "/proc/net/dev". It can be used with any system tray that follows the "Free Desktop System Tray Specification" and has a proc file system.
netwmpager is an enhanced version of the original netwmpager-1.11 program written around 2005 by Timo Hirvonen. It should be compliant with the EWMH (or NetWM) specifications. This version implements virtual desktops split into different viewports, into different desks, or both, while the earlier version only supported desks. As a consequence, netwmpager-2 should work with most window managers; it has been tested especially with compiz, fluxbox, and fvwm. It also has many parametrizable features, and it implements a convenient zoom.
