ISO14443 is a set of standards defining the communication protocols between a contactless smartcard and a card reader. There are some commercially available log tools for capturing such traffic.
I've assigned 264 for LINKTYPE_ISO_14443/DLT_ISO_14443.
Thanks.
I created a webpage at
http://www.kaiser.cx/pcap-iso14443.html
that describes the data following the pcap header.
You might want to update it to indicate that this can appear in both pcap and pcapng files, and perhaps just say that the packet time stamp must be seconds and fractions of a second since January 1, 1970, 00:00:00 UTC (not committing to it having microsecond resolution or to the time stamp having separate second and fraction-of-a-second fields; both pcap and pcapng can support, for example, nanosecond resolution, and pcapng time stamps are 64-bit fractions-of-a-second counts).
You might also want to do the same for your DVB-CI page at http://www.kaiser.cx/pcap-dvbci.html.
I updated both pages to mention pcapng and simplified the paragraphs about time stamps. All I wanted to say about time stamps is that they should be compliant to the pcap(ng) specifications. _______________________________________________ tcpdump-workers mailing list tcpdump-workers () lists tcpdump org https://lists.sandelman.ca/mailman/listinfo/tcpdump-workers
