spring currently silently ignores invalid packets. thats basicly good as this prevents reflection / DDoS attacks. not sure how to probably fix this.

I'm no network expert, but Spring already doesn't ignore those packets completely - for example it knows which network version the failed connector is trying to use (and repeatedly tells it to everyone ingame!). The host could, in principle, notify the client trying to connect without being vulnerable to DDoS.


abma (administrator)

with ignore i mean, that it doesn't send back any packet.
