Packet 0x03
The server sends Packet 0x03 Blue Burst clients to verify that a server is in place where the client is connecting, as well as to communicate the encryption vectors that will be in use for the rest of the connection. For other versions, Packet 0x02 or Packet 0x17 is used, depending on if the client is connecting to the login server or ship server
