IPNetMonitorX is a network troubleshooting toolkit for debugging Internet service problems and optimizing performance. Featuring 23 integrated tools, IPNetMonitorX is designed to help you quickly locate where the problem is and gather data which can be used to solve the problem either directly or through your Internet Service Provider.
While UNIX provides an abundance of command line networking tools, IPNetMonitorX starts by adding an intuitive Macintosh user interface, integrates them, and then extends these tools beyond what UNIX has previously offered.

Layer Four Traceroute 3.8
LFT, short for Layer Four Traceroute, is a sort of 'traceroute' that often works much faster (than the commonly-used Van Jacobson method) and goes through many configurations of packet-filters (firewalls). More importantly, LFT implements numerous other features including AS number lookups through several reliable sources, loose source routing, netblock name lookups, et al. What makes LFT unique? LFT is the all-in-one traceroute tool because it can launch a variety of different probes using both UDP and TCP layer-4 protocols.

Little Snitch 4.2
As soon as you're connected to the Internet, applications can potentially send whatever they want to wherever they want. Most often they do this to your benefit. But sometimes, like in the cases of tracking software, trojans or other malware, they don’t.
But you don’t notice anything, because all of this happens invisibly under the hood.
Little Snitch makes these Internet connections visible and puts you back in control!

Nmap ("Network Mapper") is a free and open source (license) utility for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts.

RCDefaultApp is a Mac OS X 10.2 or higher preference pane that allows a user to set the default application used for various URL schemes, file extensions, file types, MIME types, and Uniform Type Identifiers (or UTIs; MacOS 10.4 only). MacOS X uses the extension and file type settings to choose the application when opening a file in Finder, while Safari and other applications use the URL and MIME type settings at other times for content not related to a file (such as an unknown URL protocol, or a media stream).
RCDefaultApp also allows setting the application when digital cameras or FireWire webcams such as iSight are connected to the computer. For completeness' sake, there are also settings that mimic the existing "CDs and DVDs" preference pane, which allows setting the action to take when various types of CDs and DVDs are inserted into the computer.
RCDefaultApp also allows entries to be disabled, such as URL schemes that have security issues.

In 1998, Martin Roesch wrote an open source technology called Snort, which he termed a "lightweight" intrusion detection technology in comparison to commercially available systems. Today that moniker doesn't even begin to describe the capabilities that Snort brings to the table as the most widely deployed intrusion prevention technology worldwide. Over the years Snort has evolved into a mature, feature rich technology that has become the de facto standard in intrusion detection and prevention. Recent advances in both the rules language and detection capabilities offer the most flexible and accurate threat detection available, making Snort the "heavyweight" champion of intrusion prevention.

tcpflow is a program that captures data transmitted as part of TCP connections (flows), and stores the data in a way that is convenient for protocol analysis or debugging. A program like 'tcpdump' shows a summary of packets seen on the wire, but usually doesn't store the data that's actually being transmitted. In contrast, tcpflow reconstructs the actual data streams and stores each flow in a separate file for later analysis.

Vallum is a little tool that helps you with monitoring application connections. It is able to intercept an app's connections and hold them while you decide whether to pass or block them. It can be used to increase your privacy or to transparently protect non-admin users from unwanted connections on multi-user macs. Vallum's simple interface can be used by everybody to configure the firewall, its default configuration is not intrusive and it does not require any interaction or specific knowledge or maintenance.
Simply drag an app icon from the Finder into main Vallum window to block it. To change Vallum's attitude and interaction level you just have to play with the very few options available. Just run Vallum Assistant to explore Vallum's features.
Vallum does not pollute your Mac’s desktop or dock, it runs as a menulet icon in macos menu bar, near the clock. It respects your privacy too: it does not connect home to verify the license, it does not need any online activation.

WhatRoute is a network diagnostic utility designed for Apple Macintosh computers. Primarily it provides a Traceroute function, but can also perform Ping, Domain Name Service queries, Whois queries and monitor the traffic to and from your computer. The software also uses a Geo-Location service to provide a geographical view of the paths that packets from your computer take as they traverse the Internet.

Wireshark is the world’s foremost and widely-used network protocol analyzer. It lets you see what’s happening on your network at a microscopic level and is the de facto (and often de jure) standard across many commercial and non-profit enterprises, government agencies, and educational institutions. Wireshark development thrives thanks to the volunteer contributions of networking experts around the globe and is the continuation of a project started by Gerald Combs in 1998.
