I'm writing a simple(!) AppleTalk packet displaying program which tries to show meaningful information about packets picked up by the peek program. I've studied "Inside AppleTalk" and bits of the CAP sources but I'm still confused about how to recognise the different types of protocols carried by ATP. ZIP (GetZoneList, GetLocalZones, GetZoneListReply, GetLocalZonesReply, GetMyZone, GetMyZoneReply), PAP and ASP. There seems to be no way to interpret the data after the TID from the packet alone, so I guess I need more context ie. knowledge of earlier ATP transactions, yes? "Inside AppleTalk" seems to hint that the ZIP stuff can be detected by certain ATP control information and source or destination socket number 6. If this is the case, isn't it a bit of a kludge?
