The CrystalC2 server does not provide any default listeners, such as HTTP/S, DNS, etc.
It's the responsibility of the user to run their own 'listener server' that will interface with the C2 server and relay data to and from a Beacon.
In addition, users must write the corresponding agent-side code that will be merged into the Beacon.
An example repository is available here.
