A lightweight firewall for nuttx

The first step to get started with NuttX is to install a series of required tools. They can be found here.

The first step is to initialize NuttX configuration for a given board, based from a pre-existing configuration.

$ cd nuttx
$ ./tools/configure.sh -l sim:nsh

The -l tells use that we’re on Linux (macOS and Windows builds are possible). Use the -h argument to see all available options.

We can now build NuttX. To do so, you can simply run:

$ cd nuttx
$ make

$ ./nuttx
login: admin
password: Administrator
