This program detects dhcp servers on a network with dhcpdiscover packets. It can be used for detecting rogue dhcp servers, but it's designed to be small and simple to work with scripts.

Logpp is a tool for preprocessing event logs and feeding relevant data to other programs for storing or in-depth analysis. Logpp reads lines appended to input files, matches the lines with patterns, and writes the results to given destinations.

Check given IP/Host presence in 106 RBLs. Now, you don\'t have to check a lot www sites, just run this script in console.

Round Robin Database Framework is the universal, data-oriented framework on top of RRDtool. The project has recently migrated to a new name: "Torrus".

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.

Smtp Relay Checker is a network open mail relay checker. It is muti-threaded so it can be used to scan vast networks quickly, it is fully configurable so it can be adjusted to suit any need, and the scan results can be displayed in HTML. It is intended f

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

Switzerland is a tool for testing networks, ISPs and firewalls developed by the Electronic Frontier Foundation (www.eff.org). It will spot IP packets which are forged or modified between clients, inform you, and give you copies of the modified packets.

check_logfiles is a plugin for Nagios which searches for patterns in logfiles. It is capable of scanning multiple logfiles and their rotated ancestors in a single run.

PLEASE GO TO https://github.com/deksai/pam_abl A PAM module that provides auto blacklisting of hosts and users responsible for repeated failed authentication attempts. Generally configured so that blacklisted users still see normal login prompts but are guaranteed to fail to authenticate.

Lilith is a logging and access event viewer for Logback, log4j & java.util.logging. It has features comparable to Chainsaw for log4j. This means that it can receive logging events from remote applications using Logback as their logging backend

This application is developed in Java Swing Framework and here the user can select which network to monitor (displays bandwidth usage speed & network data usage). This Application also have a system tray icon support so that User can view and control the application activities via the system tray Icon Changelog: 2016 April 14th – Version 1.9 - Smashed some bugs - User can now save the log when exiting the application. Upcoming Updates: - Enhance the log functionality.

This is a Docsis cable modem diagnostic tool for Linux and FreeBSD, it can get information from Docsis 1.0 , 1.1 and 2.0 cable modems. It gathers information from the cable modem via SNMP and displays various cable parameters in real time.

A complete OpenSource Network Management System Is SNMP-Standard Oriented (tested on Cisco and Linux). It Integrates Syslog, Tacacs, RRDtool (Performance Graphs), Maps, Traps, TFTP, Autodiscovery, Sound Alerts, AAA, Modular and Extensible.

A set of Nagios plugins using snmp to monitor hosts and network equipement.

This software is a very simple network analyzer. When you click the start button, it will send a configurable stream of UDP packets to a host. (The receiving host is then required to echo all the packets back to the sender, which can be easily done via iptables rule under linux). Once the eched packets arrives back to the sender, the analyzer will calculate all the related statistics like, packet loss, jitter throughput etc... NOTE: in order to receive the echo packets you must configure the receiving host to echo the incoming packets. In the next release i will provide another java application that just echo on an UDP port.

RTG is a high-performance SNMP statistics monitoring system. Designed for service providers to collect large amounts of time-series SNMP data quickly. Data is inserted into a database to which RTG analysis, reporting and graphing applications interface

Traffic Monitor for LAN is a tool for monitoring and limiting network traffics generated by every user in LAN. Run it on the gateway PC.

As the name implies (Javascript RRD), javascriptRRD is a javascript library for reading Round Robin Database (RRD) archives (produced by rrdtool) using AJAX-like techniques. The library also provides graphing classes leveraging the Flot library.

Sockspy is a tcl program that lets you watch the conversation of a Tcp client and server.
