NetTool is a developer tool for monitoring and manipulating application-level network messages, particularly useful for debugging web applications and web services. There are two components to NetTool: the HTTP Client, and the TCP Tunnel.

PCAP Analyzer is a tool that helps analyzing network traffic captured in a PCAP format (standard of tcpdump). It has extensible Filters in charge of dissecting packets and printing information like throughput or anything that can be analyzed by Filters (e.g. packet loss, reordering, ...). It comes with several built-in Filters but can be expanded by adding custom-made Filters to the classpath. It was developped to help understanding complex network routing problems, where packets could arrive out-of-order, some were lost, or duplicated. Network analysis needed to synchronize capture on a local (destination) and remote (source) computers and display warning messages while recording traffic in PCAP format for offline analysis. PCAPAnalyzer is typically used piped to tcpdump to show warnings on console, with the possibility to replay traffic later, with different Filters.

winKnocks is an encrypted(DES) port knocking tool. Knock sequences are defined through XML files; users specify: number of packets of each knock sequence, payload and header of each packet. Logging capability. Generation of smoke packets.No replay-attack

A desktop application which is written in Java programming language. You can use it to educational purposes. This application by knowing the host IP address and the subnet mask can count network IP address, broadcast address and how many hosts can be at the network, Also shows binary operations.

The Intelligent Services Layer (ISL) is an advanced agent and service integration framework that supports distributed management; collaborative computing; intelligent software; and intelligent heterogeneous data access.

JRF is a client/server application that allows to extend local storage to other computers running the JRF Server. It has been designed for ultra-simplicity, **not for security!** It does not request for authentication when accessing files on a remote server, nor does it prevent access to files or directories. It has been designed for already-secured networks (e.g. LANs or inside VPNs), where file-sharing setup is tedious (or impossible). Basic access configuration/restriction should be performed on the OS, by changing rights of the user running the JRF Server. It is like an insecure FTP-like file sharing runnning on a single TCP port. Its Java nature gives Java programmers access to remote files as remote `InputStream` and `OutputStream`, with the added value of optionally **compressing data exchange** to ease up network usage.

Provides a remotely (or locally) scriptable JVM along with a perl & C client

KalliX is a multifunctional tool for gamers & people who'd like to manage their games, interact between games or in the games themself with other gamers. This project is (of course) OpenSource and based on the GPL license.

The Network Security Response Framework (NSRF) allows for testing different computer security response engines and methodologies. It supports simulated and real: Intrusion Detection Systems (sensors), Attacks, and Responses.

This project uses JPcap library. By using it you can view Packet level information about ongoing traffic on your network. For windows7 you need to run the Jar file as Admin.

The Plugin Framework for Java is a distributed Plugin framework. It will enable users to write distributed application by just writing simple Plugins. It will come with Plugin clustering, central plugin registry and load balancing.

SIPFlow displays SIP/DIAMETER callflows as ladder diagrams. Packets can be captured in real time, or loaded via a pcap file. SIPFlow Standard captures data on a single host and displays SIP and Diameter callflows in an intuitive graphical format. Messages are displayed as ladder diagrams on SIPFlow's main screen, but their content may be inspected by double clicking an arrow in the ladder diagram. This allows network engineers to quickly identify the behavior of their IMS network without tracing through log files or raw captures. Distributed SIPFlow captures and displays SIP and Diameter messages from remote hosts in an intuitive graphical interface. Each SIPFlow console interfaces with one or more SIPSniffers distributed across a SIP/IMS network and displays the SIP and Diameter call flows as reported by those sniffers. This is useful if your network of servers span multiple network segments or switches. Both forms of SIPFlow are able to open and display pcap files as well.

Sniffer4J is a java packet capture and manipulation tool that allows full analysis of a network. It is built upon pcap libs (winpcap, and libpcap) and can run in Windows and most Linux flavors. The current stable version (2.0) provides shared libraries (.dll and .SO) compiled and tested for both x86 and x64 architectures. Sniffer4J work’s by parsing packets in a comprehensive Pdu format. Each Pdu encapsulates the next one, making easy to navigate through the Frame. Frames can be forged in the same manner allowing them to be injected in the network. Sniffer4J support several protocols including: * Ethernet I & II (including LLC and SNAP frames) * Vlan (802.1Q) * Arp * Ipv4, Ipv6, (including options) * Next Header for IpV6 * Ipsec * TCP (including options) * Udp * Icmp (including RFC 2461 and Ipv6) * Lldp * Ipx And more to come… Remember: If you don’t test your network, some else will… Bernardo

Given a valid IP address and subnet mask, this program will return the necessary subnetwork data.

Surfboard is a filtering HTTP 1.1 proxy. It features dynamic filter management through an interactive HTML console, IP tunneling, WindowMaker applets, and a suite of filters.

wlandscape is a tool for collecting access point data of public wireless networks ( wlan ) in order to share it with anyone. It also supports gps and visualisation with the help of topographical maps. Visit our homepage for further informations.

Hostmon is a latency monitoring web app designed for ISP Support Technicians. Hostmon enables the Support Technician to provide a more rounded and detailed oriented service to his/her customers. Hostmon gives the Technician the ability to constantly monitor the network latency to hundreds of customer devices simultaneously. The Technician now has available, not only up to the minute network latency graphs for each device, but they can also view the historic latency information for monitored devices up to a year in the past. Hostmons note system lets multiple Technicians share up to the minute diagnostic information deciphered about each customer device enabling a collaborative diagnostic environment that allows customer facing issues to be identified and solved, quickly. Hostmons alert system will audibly notify the Technician immediately of any network issues causing downtime for the monitored customer devices, enabling the Technician to more effectively multi-task.
