A java wrapper for popular "libpcap" and "WinPcap" libraries. Accurate full API translation. Packet buffers delivered with no copies. Send custom packets, gather statistics. Comprehensive and easily extensible DPI engine.

Stream Control Transmission Protocol (SCTP) is a reliable, message-oriented, multihomed transport protocol. Developed by the IETF SIGTRAN working group to transport SS7 over IP, it is now the third general-purpose transport developed by the IETF.

tcpreplay is a suite of tools to edit and replay captured network traffic.

The fetchlog utility displays the last new messages of a logfile (syslog). fetchlog is similar like tail but offers some extra functionality like pattern matching with regular expressions, output formatting for email, SMS, pager or SNMP tools, etc.

tcpick is a textmode sniffer; it tracks tcp streams, shows the status, reassembles and saves the data captured in files or displays them in the terminal in different modes (ascii, hex..). There is a color-mode. Useful to get files passively.

Webminstats is a Webmin's module which display a graphical log of historic information. It's modular in design, as to be able to log everything from CPU usage to email box size.

IPplan is a web based, multilingual, IP address management, DNS and tracking tool based on php 4, simplifying the administration of your IP address space. IPplan can handle a single network or cater for multiple networks with overlapping address space.

This ASN.1 compiler turns ASN.1 specifications into C code. The asn1c is shipped together with conformant BER/DER/XER/PER codecs. The X.509, GSM TAP3, MEGACO, RRC and LDAP encoding and decoding examples are part of the source code distribution. NOTE: THE asn1c PROJECT HAS LARGELY MOVED TO GITHUB: http://github.com/vlm/asn1c

BWPing is a tool to measure bandwidth and response times between two hosts using Internet Control Message Protocol (ICMP) echo request/echo reply mechanism. It does not require any special software on the remote host. The only requirement is the ability to respond on ICMP echo request messages. BWPing supports both IPv4 and IPv6 networks.

11/21/2025 * Official distribution sites for ION and ION-core have moved to GitHub: https://github.com/nasa-jpl/ION-DTN https://github.com/nasa-jpl/ion-core * ION documentation: https://ion-dtn.readthedocs.io/ Download link for new releases (after ION 4.1.2) is posted below. Please report all issues to GitHub. Submissions to this site will not be monitored. ============================= ION development is managed by the Jet Propulsion Lab. The Interplanetary Overlay Network (ION) software distribution implements Delay-Tolerant Networking (DTN) architecture, as described in Internet RFC 9171. It is designed for use in embedded environments, including spacecraft flight computers and ground systems. ION 4.1.3s is the last version to provide both BPv7 and v6. Starting ION 4.1.4, only BPv7 code will be available.

Tracks usage of TCP/IP network subnets and builds html files with graphs to display utilization. Charts are built by individual ip. Color Codes HTTP, TCP,UDP, ICMP, VPN, P2P, etc. Click on the release notes icon for the latest release for more info.

*** This project moved to Github *** https://github.com/phaag/nfdump However, you may want to download older versions from here. nfdump is a set of tools to collect and process netflow data. It's fast and has a powerful filter pcap like syntax. It supports netflow versions v1, v5, v7, v9 and IPFIX as well as a limited set of sflow. It includes support for CISCO ASA (NSEL) and CISCO NAT (NEL) devices, which export event logging records as v9 flows. nfdump is fully IPv6 compatible.

Komari is a lightweight, self-hosted server monitoring solution designed to deliver simple and efficient infrastructure visibility with minimal resource overhead. The platform uses a lightweight agent to collect performance data from monitored nodes and presents the results through a clean web interface. Its architecture emphasizes ease of deployment and full data ownership, making it attractive for users who prefer private monitoring environments over managed services. Komari is designed to scale across servers of different sizes while maintaining low CPU and memory consumption. The dashboard provides real-time status views that allow administrators to quickly assess system health and uptime. Overall, Komari targets developers, homelab operators, and small infrastructure teams seeking a straightforward monitoring tool without the complexity of enterprise observability stacks.

Proxytunnel is a program that connects stdin and stdout to an origin server somewhere in the Internet through an industry standard HTTPS proxy. This will allow you for example to access SSH servers when you normally only have http(s) access. Please use our github page for the code and wiki/issues: https://github.com/proxytunnel/proxytunnel

Enables tunneling of network connections through restrictive HTTP proxies. Features: Portmapping, SOCKS4, SOCKS5, web-based admin interface, possibility to use standalone server (perl) or hosted server (PHP), optional authorization from LDAP or MySQL

packETH is a Linux GUI packet generator tool for ethernet. It allows you to create and send any possible packet or sequence of packets on the ethernet.

The VPCS can simulate up to 9 PCs. You can ping/traceroute them, or ping/traceroute the other hosts/routers from the virtual PCs when you study the Cisco routers in the Dynamips. VPCS is not the traditional PC, it is just a program running on the Linux or Windows, and only few network commands can be used in it. But VPCS can give you a big hand when you study the Cisco devices in the Dynamips. VPCS can replace the routers or VMware boxes which are used as PCs in the Dynamips network.

Hyenae is a highly flexible platform independent network packet generator. It allows you to reproduce several MITM, DoS and DDoS attack scenarios, comes with a clusterable remote daemon and an interactive attack assistant. *** Hyenae is back *** Hyenae will be continued here: https://sourceforge.net/p/hyenae-ng

TCNOpen is an open source initiative which the partner railway industries created with the aim to build in collaboration some key parts of new or upcoming railway standards, commonly known under the name TCN. TCN (Train Communication Network) is a series of international standards (IEC61375) developed by Working Group 43 of the IEC (International Electrotechnical Commission), specifying a communication system for the data communication within and between vehicles of a train. It is currently in use on many thousands of trains in the world in order to allow electronic devices to exchange information while operating aboard the same train. TCNOpen follows the Open Source scheme, as the software is jointly developed by participating companies, according to their role, so as to achieve cheaper, quicker and better quality results.
