Build

make build will create a build with all executables

From project directory:

$ make 
$ ./build/testrunner -help

run tests
make test

NOTE: tests don't fully pass on darwin

Build and test using docker for Mac

Build the image
docker build -t test .
Run tests
docker run -ti --rm --privileged test make test

Using testrunner

testrunner utility works fully on linux, I have not invested to make it run on docker for mac.

On docker:
docker run -ti --rm --privileged test testrunner ip link
NOTE: shows system interfaces; as i wrote before i have not investigated why.

CA creation

All certificates are generate under the ca directory by the ssl.go script which is invoked by

make ca

Start the server

For help:
server -h

With flags:
server -ca ca/ca.crt -cert ca/server.crt -key ca/server.key -listen 127.0.0.1:8080
