You need dep to install the project dependencies. Once you've installed dep, run:
dep ensure
to install the dependencies.
One of the dependencies of the project (gopacket/pcap) also needs the libpcap header files to work properly. On Linux-based distributions, you can do this by installing the development version of libpcap.
First, indicate in the config.toml file which of your network interfaces you want to listen to.
Then build the package:
go build
And run ./bonjour-reflector (you may need to run it with administrator privileges to listen to your interface).
