IT/m libnetcomm is a library which provides the required class and framework to manage TCP, TCPSSL, and UDP connections. It helps you in the task of writing network-capable software using a client-server model. This framework hides the details of the specific protocol you are using so that you can write portable, protocol-independent applications. Libnetcomm is part of a bigger project called IT/m.
Devil-Linux is a special secure Linux distribution which is used for firewalls, routers, gateways, and servers. The goal of Devil-Linux is to have a small, customizable, and secure Linux system. Configuration is saved on a floppy disk or USB stick, and it has several optional packages. Devil-Linux boots from CD, but can be stored on CF cards or USB sticks.
sinfo is a monitoring tool that uses a broadcast scheme to distribute information on the status of each computer on your local network. It supports CPU, memory usage, network load, and information about the top 5 processes on each computer. sinfo uses ncurses to display the information in an attractive manner.
vt52vnc is a VNC viewer which can be used on prehistoric green monochromatic terminals called vdt52s, which are capable of vector graphics. It is functional and nicely displays X on the terminal, but without the routines for dithering, compression, and password support. Its architecture provides a framework to add those features if needed.
EndoShield is a fully configurable firewall that will run under a 2.2 or 2.4 Linux kernel (ipchains or iptables). It requires no knowledge of firewalls or how ipchains or iptables works. It is perfect for home users wanting to secure their systems, but can also be configured for internet connection gateways or server systems.
ipband is a pcap-based traffic monitor. It tallies per-subnet traffic and bandwidth usage and starts detailed logging if the specified threshold for a specific subnet is exceeded. This utility could be handy in a limited bandwidth WAN environment (frame relay, ISDN, etc.) to pinpoint offending traffic sources if certain links become saturated to the point where legitimate packets start getting dropped.
