conky
Light-weight system monitor for X
Conky is a free, light-weight system monitor for X, that displays any kind of information on your desktop. Conky is free software and runs in X on Linux and BSD. Originally a fork of Torsmo, Conky's torsmo-based code is BSD licensed. New code in Conky has been licensed under GPL 3.0. Since its inception, Conky has changed significantly from its predecessor, while maintaining simplicity and configurability. Conky can display just about anything, either on your root desktop, in its own window. Not only does Conky have many built-in objects, it can also display just about any piece of information by using scripts and other external programs. A plethora of OS stats (uname, uptime, CPU usage, mem usage, disk usage, "top" like process stats, and network monitoring, just to name a few). Conky can display information either as text, or using simple progress bars and graph widgets, with different fonts and colours. -

NDPMon
NDPMon - Neighbor Discovery Protocol Monitor
The Neighbor Discovery Protocol Monitor (NDPMon) is used by Internet Protocol version 6 network administrators for monitoring ICMPv6 packets. NDPMon observes the local network for anomalies in the function of nodes using Neighbor Discovery Protocol (NDP) messages, especially during the Stateless Address Autoconfiguration. When an NDP message is flagged, it notifies the administrator by writing to the syslog or by sending an email report. It may also execute a user-defined script. For IPv6, NDPMon is an equivalent of Arpwatch for IPv4, and has similar basic features with added attacks detection. NDPMon also maintains up-to-date a list of neighbors on the link and watches all advertisements and changes. It permits to track the usage of cryptographically generated interface identifiers or temporary global addresses when Privacy extensions are enable (default behavior in Ubuntu and Windows for example). -
