Protocol:Packet 0x02
The server sends Packets 0x02 and 0x17 to non-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.
Packet 0x02 is used for ship/block ports, and 0x17 is used for the login server.
