Free network applications software for linux

My Network Catalog is an indexing engine that allows Windows shares (or Samba shares) to be bound together over a local network.

My Network Catalog allows an easy centralized search of all the files available over the network.

network-config is a simple network configuration tool.

Network-config is a simple and easy to use program that helps configuring the network interfaces for linux-based operating systems. It allows to have multiple configurations for the same computer and to easy configure NAT for internet sharing.

It can also be used to scan for wireless networks. It is written in perl and uses gtk2+, but also works as a command line program.

NetworkX is a Python package for the creation, manipulation, and study of the dynamics, structure, and functions of complex networks.
Main features:
- Allows for 1M+ nodes, 10M+ edges
- Includes standard graph-theoretic and statistical physics functions
- Easy exchange of network algorithms between applications, disciplines, and platforms
- Includes many classic graphs and synthetic networks
- Nodes and edges can be "anything" (e.g. time-series, text, images, XML records)
- Exploits existing code from high-quality legacy software in C, C++, Fortran, etc.
- Open source (encourages community input)
- Unit-tested
Additional benefits due to Python:
- Allows fast prototyping of new algorithms
- Easy to teach
- Multiplatform
- Allows easy access to almost any database

This program will help you to view network activity on your network device such as eth0, ppp0 and so on.

It put animated, graduated, icons near the KDE tray.

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.

LUA is a small scripting language designed to be embedded inside your application to provide extensibility.
It is also possible to extend the Lua scripting language itself via the use of extensions written in C. This page describes such an extension which provides a small number of basic networking and filesystem primitives.
By installing this extension you will be able to write networking applications in the Lua!
Enhancements:
- Added some filesystem primitives.
- Added API documentation & examples.
- The HTTP server now falls back to a default virtual host if none is specified, or if the attempted one doesnt exist.
- The HTTPD server now supports directory indexing if no index.html file is found in a directory.
- The HTTPD server now writes access.log files to each virtualhost.
