Libntoh aims to be a user-friendly library to provide an easy way to perform defragmentation and reassembly of network/transport protocols. It is intended to provide a flexible, thread-safe, and highly configurable environment for the user. It performs IP defragmentation and TCP reassembly.
Counters.pl collects the CLI counters from network devices and produces custom reports. These counters can be reset independently of the SNMP counters, and when collected weekly, can highlight issues such as connection errors that you will not see looking at graphs produced from SNMP counters. They also contain information that is not available via SNMP. The reports can be viewed on a Web site and/or sent via email. There is a flexible configuration language in which reports can be specified. The format and style of the HTML reports are controlled by Template Toolkit templates and CSS. Currently only Cisco network equipment is supported.
log2command was created as a sort of reverse fail2ban or cheap VPN-firewall: a machine with a closed firewall can be told, by a foreign machine, to accept connections from a specific IP. log2command then keeps track of the Web server log file and watches for inactivity from the user's IP. After an amount of time, another command is executed that can remove the user's IP from the firewall, closing down the machine again. The PHP script is a command line program that can be run in the background.
MuLaNEO implements algorithms to design and provision resilient multi-layer networks, or hierarchies of technologies (IP/MPLS, Carrier Ethernet, SDH/SONET, etc.). It includes modelling of these technologies, visualizes their interrelations, and allows the dynamic provisioning of the resulting networks on the basis of path computation elements (PCE).
Netzob supports the expert in reverse engineering, evaluation, and simulation of communication protocols. Its main goals are to help security evaluators to assess the robustness of proprietary or unknown protocol implementations, simulate realistic communications to test third-party products (IDS, firewalls, etc.), and create an Open Source implementation of a proprietary or unknown protocol. Netzob provides a semi-automatic inferring process, and includes everything necessary to passively learn the vocabulary of a protocol and actively infer its grammar. The learnt protocol can afterward be simulated. Netzob handles text protocols (like HTTP and IRC), fixed field protocols (like IP and TCP), and variable field protocols (like ASN.1-based formats).
