The spec sheet that was used to write this dissector was * Revision 3.1a of November 26, 2007. * * Protocol Structure * * All messages have an eight byte header. The first 4 bytes represent the package * length. This length doesn't include the length of the base header. Next, is the * message base type which is also 4 bytes. All ged125 messages have this format * unless a message spans across several packets. The most common message is the * service control type. This message type will have its own header and with in * that header have a few other things. One of these things is a sub-message type. */ #include "config.h" #include #include #include #include "packet-tcp.h" void proto_register_ged125(void); void proto_reg_handoff_ged125(void); static int proto_ged125;
