This is a reference book for everyone who practices Network Sciences and all students here. It is available to everyone here, and contains topic specific examples of network operations such as ARP, DHCP, DNS and more.
Curious or forget how a network fundamental operation works? Consider this your reference.
Every IT/Network Scientist needs a set of tools - a tool belt - to help them set up, manage, and troubleshoot todays complex network systems.
Preferably the tool belt comes at zero or little cost, or maybe it is open source.
Each section in this reference lists a different tool with key information about the tool.

As the Internet has grown and evolved, its library of content has grown exponentially. The problem is to limit context and applicability. Hence the development of our own video library focused on Network Sciences. Within this section of our Reference Library you will find a host of categorically arranged videos and references. We encourage you to browse, watch, and learn.
This reference contains several great tutorials on how to use Git to manage releases of just about anything, but for us Network Scientists it is about managing network automation!
This reference describes what Ansible is and how it can be used for network/datacenter configuration from templates.
Nmap ("Network Mapper") is a free and open source (license) utility for network discovery and security auditing. Nmap was named “Security Product of the Year” by Linux Journal, Info World, LinuxQuestions.Org, and Codetalker Digest. It was even featured in twelve movies, including The Matrix Reloaded, Die Hard 4, Girl With the Dragon Tattoo, and The Bourne Ultimatum. Learn how yo use this free tool here.
Scapy is a powerful interactive packet manipulation program. It is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, match requests and replies, and much more.
Get introduced to what TCPDUMP is and how it works. For many of us, this was the first way we captured packets.
SNORT is an open source intrusion prevention system capable of real-time traffic analysis and packet logging. It usually is run in the background and uses customizable rules to kill, log or alarm when certain types of traffic occur. Available for Windows or Linux.
Ettercap is a stand alone tool that allows you to sniff traffic on a local network, perform man-in-the-middle penetration testing and ethical hacking.
Ettercap is included in Kali Linux and learning to use this tool is a great way to understand key networking concepts.
Pinkie is a suite of network troubleshooting utilities that support both IPv4 & IPv6, packaged in an intuitive, easy to use user interface. It can continuously ping multiple hosts at the same time, perform forward, reverse and bulk DNS lookups as well as traceroute automatically. Results can be logged to disk or copied to the clipboard with a click of a button.
Iperf is a tool to measure maximum TCP bandwidth, allowing the tuning of various parameters and UDP characteristics. Iperf reports bandwidth, delay jitter, datagram loss. Iperf was orginally developed by NLANR/DAST as a modern alternative for measuring TCP and UDP bandwidth performance. Learn how yo use this free tool here.
Check out how to set up and use OpenStack Neutron for network creation, learning and testing.
This course contains a collection of Wireshark Tips from the great folks at HakTips. We hope you enjoy these basic Wireshark Videos, and thanks to the Hak5 team for creating these short overviews. Enjoy!
Using the Internet as a digital learning tool is essential to anyone in Networking Sciences today. As our course attendees know, we try to keep our video learning segments to around 20 minutes or less. TED Talks have a similar requirement. Plus these talks are a great way to learn new things. This course contains our favorite TED Talks, and we encourage you to watch them as well.
