- Poseidon is a solution for the GameGuard problem. Server like bRO use
- GameGuard. The RO server sends a packet to the client, and the client
- must response with an appropriate packet.
- Overview
- --------
- Poseidon works like this:
- 1. Poseidon sets up a fake RO server (let us call it PoseidonRO).
- 2. Poseidon sets up another server socket for communication with OpenKore.
- 3. OpenKore connects to Poseidon.
- 4. RO client connects to PoseidonRO.
- 5. Real RO server sends GameGuard query to OpenKore.
- 6. OpenKore sends GameGuard query to Poseidon.
- 7. Poseidon sends GameGuard query to RO client.
- 8. RO client sends a reply.
- 9. Poiseidon sends reply to OpenKore.
- 10. OpenKore sends reply to real RO server.
- Protocol
- --------
- The Poseidon server uses the same message format as the bus system.
- See the Bus::Messages module for information.
- A request to the Poseidon server is as follows:
- Message ID: "Poseidon Query"
- Key 'packet' - The GameGuard packet, as sent by the RO server.
- The Poseidon server replies with the following message:
- Message ID: "Poseidon Reply"
- Key 'packet' - Response to send back to the GameGuard server.
- Server files
- ------------
- poseidon.pl, QueryServer.pm and RagnarokServer.pm are part of the Poseidon
- server.
- Client files
- ------------
- The Poseidon::Client module provides a simple interface for OpenKore to
- communicate with the Poseidon server.
