Warn of duplicate network id

Please consider having either ZeroTier Central or ZeroTier One warn when two machines have the same id.

The network id can become duplicate a machine is cloned and one forgets to generate a new id on either the new or the old one, and both remain online. That will result in lack of proper connectivity and attempting all sort of vodoo to fix it until one realizes it’s the duplicate network ids.

Agree. This should be visible at server side and via the API.

@elmimmo Anyway, how do you generate a new ID on the client side?

Cannot remember what I did but I guess I followed this Duplicate Nodes - #2 by zt-joseph or something similar.
