Free network analyzer software for linux

Network Traffic Analyzer analyzes the network traffic on multiple network devices and creates HTML statistics with some network usage graphs. Sometimes it is good to know, how the network is used, how many bytes were received and how many bytes were sent.Therefore, here is Network Traffic Analyzer, which creates simple network usage statistics.


Such statistics can tell you, how good your network connection really is (who cares about what Internet provider say, when was the network down, which time is the best time for downloading large packages of data etc. etc. Or with this software you can just better imagine, how many traffic can your home computer generate.

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.

Netleak is a collection of small perlscripts that detects connectivity between network segments. It is mostly useful to detect "leaks" in large organizations that have private networks physically separated from the Internet.


Imagine some large corporation which has an internal development LAN were all sorts of sensitive information is flowing around. This corporation would likely have some very strict rules as to how its employees access the internet or other partner branches in order to
protect its information. For the systemadinistrator this is a daunting task - as the corporate LAN grows keeping track of all the routes through the network becomes extremely difficult. Some routers might simply have been forgotten over time or an employee might have gone wise and connected his own adsl-router or something alike.

Network Leak Finder tries to detect this in a centralized manner by sending out spoofed packets into the internal network and if any packets finds a way onto the external network, a "leak" has been detected. As an anology it works the same way you would find a hole in
a bucket: fill it with water and see if anything leaks.

In most scenarios the external network would be the Internet since everybody should be afraid of what their corporate LANs are leaking to it!
