Rippled setup questions

[tulo]

So I'm finally running my rippled (non-validating for now).
But I have a few questions:

-How to enable verbosity?
-How to know when my node is synced?
-How to setup servers and ports to be able to connect via ws from any device in the subnetwork (192.168.1.XXX), but drop any connection from outside?
-I get [RippledNotInitializedError(Rippled not initialized)]. What is the cause?
