Network Traffic Analyser provides a script-driven network traffic monitor.

Network Traffic Analyser (formerly known as sniffer) is designed to be an extremely powerful, configurable, and versatile tool for monitoring network traffic.

It can be used as a plain sniffer, as a tool for accounting, dynamic firewall updates, and many more things.

It features scripting support and an event-driven architecture.

The idea behind this project is to create a powerful tool for playing around with network traffic. The basic concepts are simplicity and flexibility. Instead of building tool that does something specific (and does a good job at it), were trying to build a tool that will be able to do whatever you want it to do (and still be good at it :).

To put it very simply, you write a script that will be invoked for every packet that passes through your network. You write your scripts in a Tcl, fully blown, interpreted programming language. That fact guaranties that you wont be constrained in your creativity.

Network Tracker application is a user (MAC) tracker daemon, for big LANs (campus).
The Network Trackerd builds a table which records which user is connected on which port of a switch by scanning the devices with SNMP in your inventory which is in a MySQL database. Trackerd keeps that table up-to-date by scanning the network regularly.
Thus, you will have the opportunity to know exactly where a user (MAC, IP, UID) is connected on your network !
Your devices are also checked with ping and SNMP, and you are informed with e-mail when any of the devices is not alive.
More over, you may produce various reports about your network infrastructure on the web (cgi) or by using other tools.
Network tracker eases especially to find and shutdown the switch port of the users, when their PCs on the network start to spread viruses or warms using lots of bandwith; so you are able to stop that kind harmfull traffic on the network.
Main features:
- Collects all the MAC addresses and port numbers from CAM tables of the switches.
- Finds IP addresses of the MACs from ARP tables of the routers.
- Finds LDAP uid of the user.
- Check devices on the network with both ping and SNMP for better reliability.
- The daemon sends 2 self check e-mail per day.
- Developped with C.
Enhancements:
- trackerd is now multi-threaded and works very quickly because a new thread is created for each network device.
- MAC tracking code has been reimplemented for multi-threaded use.
- Wireless access point support has been added.
- gnuplot graphics are prepared, showing the active number of users like MRTG graphs.
- tracker now accepts MAC addresses in free format.

The Torque Network Library project is a robust, secure, and easy-to-use cross-platform C++ networking API designed for high performance simulations and games.
It features a UDP- based connection architecture with DoS prevention functionality, different types of data guarantee, bit stream compression, server object replication and updating, and a simple, highly space efficient RPC mechanism.
It includes a deterministic application journaling replay function for eliminating hard to find networking bugs.
Main features:
- Portable
- Powerful RPC Support
- Lightweight and efficient - not intended to be a replacement for CORBA.
- Extremely easy to use - two simple macro definitions and youre done.
- No complex wrapper classes to work with - write and call your functions as you normally would, and TNL will take care of the rest.
- Robust UDP-based notification protocol
- Supports fixed or adaptive rate data transfer.
- Arbitrary sized packet window.
- Robust connection handshaking.
- Handles packet loss/out of order delivery.
- Networked Objects
- Instantiation of objects by name or ID.
- IDs are assigned to NetGroups, so that only objects relevant to a connection can be references.
- Event Support
- Unguaranteed, guaranteed unordered, or guaranteed ordered event delivery.
- Notification to the event when it has been received or dropped by a client.
- Ghost Support
- Most-recent state information is transmitted to clienst.
- Scoping of objects to only those clients for which they are relevant - this helps prevent cheating or data sniffing and makes dramatically more effective use of available bandwidth.
- Prioritization of state updates by arbitrary criteria, such as relative velocity, team, ownership, etc.
- Extensible Protocol Architecture
- Easy to extend the protocol, for instance, to transmit player move information with every packet, or add voice support.
- See Torque for examples of additional capabilities that could be added to the protocol.

Dell 1600n network scanner driver is a driver for network scanning using a Dell 1600n Printer/Scanner/Fax/Copier.
It is implemented as a Perl script. In principle, this means that it should be cross-platform.
It has been tested under Linux (Debian) and Windows (NT4 with Cygwin) on Intel. Supported formats are TIFF and JPEG. With an external program (e.g. ImageMagick convert), PDF is supported.
Main features:
- TIFF and JPEG network scanning using a Dell 1600n MFP.
- PDF scanning support via an external program (eg: ImageMagick convert)

gnetload network load meter project is a network and ISDN load meter that is similar to xisdnload, but works in a distributed environment.
It includes an agent (devstata) that runs on machines with interfaces to be monitored and periodically sends status information over the network. A display program (gnetload) collects and displays the data.
Both can be run on the same machine, or be used to report on the state of a dedicated router on another machine. Using multicast or broadcast addresses, data can be fed to more than one instance of gnetload. A menu for taking network interfaces up and down is also provided.
Usage: ./gnetload [-I] [-t tickscale] [-g geometry] [-d] [ip]:port
Enhancements:
- The config script was updated to build with GTK2 and GCONF2 where available.
- There are no other code changes.
