Ettercap is a suite for man in the middle attacks on LAN. It features sniffing of live connections, content filtering on the fly and many other interesting tricks. It supports active and passive dissection of many protocols (even ciphered ones) and includes many feature for network and host analysis.
GNS3 is a graphical network simulator that allows simulation of complex networks. To allow complete simulations, GNS3 is strongly linked with : Dynamips, the core program that allows Cisco IOS emulation. Dynagen, a text-based front-end for Dynamips. Qemu, a generic and open source machine emulator and virtualizer. GNS3 is an excellent complementary tool to real [...]
namebench hunts down the fastest DNS servers available for your computer to use. namebench runs a fair and thorough benchmark using your web browser history, tcpdump output, or standardized datasets in order to provide an individualized recommendation. namebench is completely free and does not modify your system in any way. This project began as a [...]
Kismet is an 802.11 layer2 wireless network detector, sniffer, and intrusion detection system. Kismet will work with any wireless card which supports raw monitoring (rfmon) mode, and can sniff 802.11b, 802.11a, and 802.11g traffic. Kismet identifies networks by passively collecting packets and detecting standard named networks, detecting (and given time, decloaking) hidden networks, and infering [...]
AirFart is a wireless tool created to detect wireless devices, calculate their signal strengths, and present them to the user in an easy-to-understand fashion. It is written in C/C++ with a GTK front end. Airfart supports all wireless network cards supported by the linux-wlan-ng Prism2 driver that provide hardware signal strength information in the "raw [...]
In one of my previous post, Open Source Business Solutions – ECM, CRM, CMS…, I wrote about Hyperic, which is the open source network management and monitoring tool that I used. Recently I got to test out other open source network management software. The ones that I have tested are Zenoss, Nagios, and OpenNMS. Zenoss [...]
Download Several years back I was programming a network utility that needs an index relating IP network numbers to network names and identities, for class A, B and C networks, I found this list compiled from the Internet. I know that you can always use whois, or some online website to achieve the same thing. [...]
