Detailled information about the file type support can be found in the source code files wiretap/libpcap.c and .h. Ethereal handles all capture file I/O in the [http://anonsvn.ethereal.com/viewcvs/viewcvs.py/trunk/wiretap/ wiretap] library. You'll find further details about the libpcap file format in the source code files wiretap/libpcap.c and .h :-)

libpcap file format (.pcap)

The libpcap file format is used by a wide range of open (and closed) source programs.

History

The current libpcap file format version 2.4 is available for quite a long time now.

Programs supporting this file type

Timestamps

The common timestamp resolution is 1 us. A special libpcap format is available (supported by Ethereal only), providing 1 ns timestamp resolution.

Ethereal

The libpcap support is fully functional. Ethereal supports reading and writing of this format.

Ethereal handles all capture file I/O in the [http://anonsvn.ethereal.com/viewcvs/viewcvs.py/trunk/wiretap/ wiretap] library. You'll find further details about the libpcap file format in the source code files wiretap/libpcap.c and .h :-)

Example capture file

XXX - Add a simple example capture file to the SampleCaptures page and link from here (see below). Keep this file short, it's also a good idea to gzip it to make it even smaller, as Ethereal can open gzipped files automatically.
