FrazierWall Linux is a single floppy distribution Linux firewall that is based on the Linux Router Project. It is designed for use with ethernet base internet connections (such as cable modems or xDSL lines). It allows you to share such a connection with several other computers on a LAN. It is easy to setup and maintain, and is available in a Linux configurable software version.
NeTraMet is a network accounting meter. It builds up packet and byte counts for traffic flows, which are defined by their end-point addresses. Addresses can be ethernet addresses, protocol addresses or 'transport' addresses, or any combination of these. NeTraMet provides a valuable tool for analysing network traffic flows, and should prove to be of interest to anyone interested in network monitoring, capacity planning, performance measurement, etc.
