On osx (10.8) the "struct you_spacket" is 48 bytes. struct you_spacket { char type; /* SP_YOU */ char pnum; /* Guy needs to know this... char hostile; char swar; char armies; char tractor; char pad2; char pad3; unsigned flags; LONG damage; LONG shield; LONG fuel; unsigned short etemp; unsigned short wtemp; unsigned short whydead; unsigned short whodead; }; Packet dump after the MOTD stuff looks like this for me. 0c100000 00000000 08000000 00000000 00000000 00000000 00000000 00000000 18000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 16000000 02000000 03000000 00000000 14000000 12000000 00000000 04000000 00000000 00000000 18010000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 16010000 02010000 03010000 00000000 14010000 12010000 00000000 Byte 0x0c (12) is SP_YOU #define SP_YOU 12 /* info on you? */ The next 48 bytes should fill in the "struct you_spacket" but that leaves 2 nybles of null bytes before the byte 0x18 (24) SP_PL_LOGIN is seen #define SP_PL_LOGIN 24 /* new player logs in */ In my code I replaced the (I assume) autoconf figured out LONG with long is that right? I'd look at MacTrek but that's a 32-bit project and I'm attempting to write my stuff as a 64-bit project. Why I'm confused is the MacTrek project has the SP_YOU structure at 32 bytes, which would even leave more null bytes. Just trying to figure out why I'm ending up 2 nybles short.
