Open Source Networking Software

Network Security Toolkit (NST) is a bootable ISO image (Live USB Flash Drive) based on Fedora 42 providing easy access to best-of-breed Open Source Network Security Applications and should run on most x86_64 systems. The main intent of developing this toolkit was to provide the security professional and network administrator with a comprehensive set of Open Source Network Security Tools. The majority of tools published in the article: Top 125 Security Tools by INSECURE.ORG are available in the toolkit. An advanced Web User Interface (WUI) is provided for system/network administration, navigation, automation, network monitoring, host geolocation, network analysis and configuration of many network and security applications found within the NST distribution. In the virtual world, NST can be used as a network security analysis, validation and monitoring tool on enterprise virtual servers hosting virtual machines.

FlowViewer provides a convenient web-based user interface to Mark Fullmer’s flow-tools suite and CMU's netflow data capture/analyzer, SiLK. The inclusion of the underlying SiLK tool set enables FlowViewer users to continue to use the tool with the newer IPFIX netflow data protocol, which includes support for IPv6 and Cisco's v9 and FNF netflow. FlowViewer has been developed for NASA’s Earth Sciences Data and Information System (ESDIS) networks, and credit goes to NASA for their usual outstanding support of innovation. The FlowViewer tools provide additional graphing and tracking features by utilizing open source software including Thomas Boutrell’s gd, Lincoln Stein's GD, Martien Verbruggen's GD::Graph, and Tobias Oetiker’s RRDtool. FlowViewer v4.6 fixes non-UTC local time environments for FlowViewer and FlowGrapher, and $no_devices_or_exporters FlowMonitor_Collector problem. **Note: SiLK must be v3.8.0 or later. Version 3.9 handles sFlow data.

GGI stands for "General Graphics Interface", and it is a project that aims to develop a reliable, stable and fast graphics system that works everywhere. We want to allow any program using GGI to run on any platform requiring at most a recompile.

Rootsector module allows you to automate some attacks over DNS_SPOOF + MitM (phishing - social engineering) using metasploit, apache2 and ettercap frameworks. Like the generation of payloads, shellcode, backdoors delivered using dns_spoof and MitM method to redirect a target to your phishing webpage. recent as introducted the scanner inurlbr (by cleiton)

Are you tired of manually changing your IP Address? All that left clicking then right clicking through menu's - don't get me started on the tabbing too...well I am tired of it! That's why I developed Easy IPChange a light, fast and easy to use script to quickly change the IP address of any network adapter. Easy IPChange can be launched directly and used with a nice batch GUI or even automated with CLI arguments! Sweet! IP change has been developed as a batch script (.bat) designed for the XP command interpreter however is forwards compatible with any current windows OS (Win7 & 8 may need to 'run as admin'). Changing your IP Addy is as easy as: IPCHANGE /IP 192.168.0.2 /MASK 255.255.255.224 /DG 192.168.0.1 IPCHANGE /DHCP Easy IPChange is the best free IP Changing script out there so check it out! If you don't like it - tell me about it...and if you do - Win Win! Check out the Youtube vid http://www.youtube.com/watch?v=nfee-10CaJk&list=UUq-H3HcL6KzIx2R7ApsNGrA
