.NET File Extension

You most likely will only encounter netViz NET project files if you work in a business setting and use netViz to visualize data related to large information systems. The software was used in the 1990s and 2000s but is no longer developed. Therefore, NET files are rather obscure nowadays.

NET project files are the main file type associated with netViz and can only be created and opened with the program. The file type is the most well known among netViz users since the files store saved projects and are opened directly by users when opening projects.

NOTE: Example projects included with netViz software are often called "Global Network.net" or "Global.net."

Dynamips is a Cisco router emulation software that allows network engineers and administrators to configure and connect to virtual copies of Cisco routers. Dynagen is a command-line program that allows engineers and administrators to build entire virtual networks atop Dynamips' virtual routers.

To create a network, engineers and administrators must define the network's included servers, ports, routers, and other settings in a Dynamips NET file. These files are plain text files saved with the .net extension. In addition to specifying the server, port, and router settings, users must also specify the path to their Cisco router disk image and the location at which to save their network's working files.

GNS3 is a GUI-based frontend that allows network engineers and administrators (and often, those preparing to become engineers or administrators) to create Dynagen-style virtual networks without interacting with the command line. GNS3 also uses NET files to specify and load network configurations.

Because NET files are plain text files, you can open and edit them using any text editor, such as Notepad (Windows), TextEdit (Mac), or Atom (multiplatform).

After you've finished configuring your NET file (and assuming you have installed Dynagen), you can double-click the file during the Dynagen network setup process to create your Dynagen network.

Rabbit is a Linux web server developed by Kevin Rossi, also known as kevidryon2. It is written in C and can be installed in any directory.

If a Rabbit user wants to control how the web server responds when a user makes a specific request, they can do so by creating a related NET script (written using Rabbit-specific syntax). They must then compile the script to the BNS format, using Rabbit's included NetC compiler. Finally, they must place the BNS file in Rabbit's ~/​scripts directory.

You can open and edit a NET file with Microsoft Visual Studio Code or any other text or source code editor. To use a NET file with Rabbit, you must compile it using the web server's included NetC compiler.
