Hey again, I''ve got a problem with my networking subsystem. I''m connecting two sockets together through TCP - one is listening on port 52, and the other connects to 127.0.0.1:52. The connection appears to be OK, but when I send some data through, it just disappears while ''on the wire'' - I get told that the number of bytes sent was indeed equal to the number I gave it, but the SocketReady() call at the other end always returns false. As such, is there anything I can use to view sockets on the local system, connections between them, and packets that are moving around? I''m aware that this isn''t too far from skr1p+ k1dd13 territory, but I don''t want to resort to that kind of program (partly due to my own principles, but partly due to the general unreliability of such software).

Download and install WinPCap. Once you have that, you can either use the example source code to view packets or you can download a program like Analyzer to view them in a GUI.

Ah, thanks very much. I''ve actually fixed the problem now (SDLNet *requires* you to add sockets to groups and call CheckSockets() on them, which wasn''t clear from the header - CheckSockets() seems to make the select() call), but I''ll pick up WinPCap anyway.
