MIB Navigator is a Java-based GUI application for exploring SNMP MIBs and querying hosts running SNMP agents. Rather than providing persistent network monitoring, it serves as a investigative tool. OIDs are represented as nodes in a tree structure.

Netmap can be used to make a graphical representation of the surounding network. It first uses traceroute to make a list of all routers and their interconnections, after which it generates a .dot file. You need the Dotty program to view the graphical rep

Small tool for locate and display active DHCP servers on the subnet.

PADS is a signature based detection engine used to passively detect network assets. It is designed to complement IDS technology by providing context to IDS alerts.

This is a ping monitoring tool for almost any Windows System (tested on Win 98*-10 and Server 2003-2016) and it runs on Linux via WINE either*. No .NET is needed. This is a 32bit app and will work on x86 and x64 architectures. Adjustable and easy to use. And you can choose if you want it to create RAW packets instead of using Windows icmp.dll resources. Usage examples: PingMon.exe HOST1 HOST2 Will open 2 instances of PingMon and start pinging immediately. Since Windows shortcuts are limited, there also is a way to run a batch file like this: start PingMon.exe HOST 1 start PingMon.exe HOST 2 ... start PingMon.exe HOST 33 The numbers are used for positioning. Version 0.3 and later contain another tool, PingHist, to visualize log files again: PingHist.exe LOGFILE Will visualize file LOGFILE. *) Versions 0.2 and higher don't run on non-NT systems. This is due to elevation detections. So, on Windows 98 you will have to run 0.1 versions No further dev.

Simple Event Correlator (SEC) is a lightweight event correlator for network management, log file monitoring, security management, fraud detection, and other tasks which involve event correlation.

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.

This is a small and free program to ARP Ping your LAN and to send Wake on LAN datagrams to devices in your LAN. All found and active physical adresses, which will be discovered by ARP sweep pings will be stored in a list and saved to disk. You are able to search for certain hosts and also to send out Wake On LAN requests to stored devices. Devices can be grouped together so Wake-on-LAN requests can be send out to many hosts at once with ease. The software needs .NET 2.0 RTE installed.

Coffee will keep your computer wide awake while your network is active or a program. Coffee prevents standby when your traffic speed on a selected network adapter is above the user configurable threshold or specific software selected. It will keep computer awake without disturbing monitor sleep mode. Have option to delay xx minutes after software does not meet sleep block settings. Have option to send up key press.

Intrusion Block (IBlock) is a small Linux daemon which greps the alertfile of an IDS such as Snort or Suricata and blocks the offender hosts for a given amount of time using iptables.

OpenLLDP is an Open Source implementation of the IEEE standard 802.1AB Link Layer Discovery Protocol (LLDP). The OpenLLDP project aims to provide a comprehensive implementation of IEEE 802.1AB to help foster adoption of the LLDP protocol.

QOS is a monitoring system. It can monitor Cpu, Disk, Memory, etc. on a large number of hosts (300+). It can also monitor web sites, DNS, and other network services, and can generate reports from the collected monitor data.

Looking Glass for Cisco,Juniper & Zebra/Quagga routers with AS-name lookups and community name translations (requires PHP+MySQL)

netleak is a collection of small perlscripts that detects connectivity between network segments. It is mostly useful to detect "leaks" in large organizations that have private network segments physically separated from the Internet.

Traff sniffs you network interfaces and accounts the traffic on a IP basis. The configuration is very flexible allowing you to create different/multiple accounting rules. The collected data is stored using Mysql, PgSQL, Syslog or files.

Show system and ISDN information on external liquid crystal displays

The program thrulay is used to measure the capacity, delay, and other performance metrics of a network by sending a bulk TCP or UDP stream over it.

Autostatus is a network monitoring program for hosts and services. It is designed to be fast and extremely easy to use. It monitors by icmp pings and by attempting TCP connections to specified ports.

The goal of FireStarter is to provide easy to use, yet powerful, graphical tools for setting up, administrating and monitoring firewalls for Linux machines.

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.

Knocker is a simple, versatile, and easy-to-use TCP security port scanner written in C, using threads. It is able to analyze hosts and the network services which are running on them. It is available for Linux, FreeBSD, Unix, and Windows95/98/2000.

Bacula-Web is a web based UI mostly written in PHP which provide you a summarized view of your Bacula's backup infrastructure. It obtain his information from your Bacula catalog's database. Latest stable version is available on https://www.bacula-web.org (Bacula-Web 9.5.0 - released on March 18th 2024).

A native Cocoa app that can browse all registered domains, list all services, instances, and TXT records

NetMonitor is a simple program for monitoring upload and download data on the internet, developed using Python and the tkinter library. It provides real-time insights into your network's performance, allowing users to easily track data usage and active connections

PerfMon is a simple but very usable performance monitoring tool for network elements like routers and switches. It's high performance polling enigne uses very little cpu processing and can handle multiple unreachable elements without locking up.
