Networking/Computing Tips/Tricks

Monitoring, analyzing, managing, and diagraming a network can often be a huge problem for Network and System Administrators.  They are often vendor specific or cost large sums of money to license.  We also have the challenge of so many different network infrastructures, like Wi-Fi and wired.

If you are looking for a tool that may save you money, or is relatively vendor agnostic, you may find something useful in the following list.  

We have expanded the list to include some other essential tools as well.

Not all these tools are perfect, nor all encompassing.  You may need to use some in combination depending on your needs.

Below, I have compiled a list of tools below that may be possible solutions.  They are in no particular order per se.  I did put Wi-Fi stuff in the middle and stand alone, application specific (sniffers, etc.) towards the end of the list.

nmap/Zenmap

Website: https://nmap.org/download.html

Cost: Free

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. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), a utility for comparing scan results (Ndiff), and a packet generation and response analysis tool (Nping).  Nmap was named “Security Product of the Year” by Linux Journal, Info World, LinuxQuestions.Org, and Codetalker Digest.
