The correct dissection of packets and timestamps (relative) is the screenshot. Timestamps have nanosecond precision and the packets contain a valid FCS.

This file contains 8 ICMP packets (a ping operation). Please note: The recommended file name extension for pcapng files is. Many_interfaces.pcapng (SHB, 11 * IDB, NRB, 11 * ISB, 64 * EPB) The is a version of this same file that was edited by hand to illustrate how a big-endian and little-endian machine might write the same data.ĭhcp_little_endian.pcapng (SHB, IDB, NRB, 4 * EPB encoded in little-endian format)ĭhcp_big_endian.pcapng (SHB, IDB, NRB, 4 * EPB encoded in big-endian format) The '' file was found as an attachment(under a different name) in an email regarding pcapng.

A few of these files were found elsewhere on the net (most likely the at the site referenced above).

Examples of pcapng files are currently very scarce. While the block headers for these files appears to be formatted correctly, the payloads contained within these may NOT necessarily be well-formed (this is especially true of the '' file). Included below are some example pcapng files. Some extensions to the pcapng format from the Linux-Sensor project.

The pcapng file format specification is still work in progress, see: The PCAP Next Generation Dump File Format (or pcapng for short) is an attempt to overcome the limitations of the currently widely used (but limited) libpcap format. WARNING: This wiki page is woefully out of date. Create pcap files instead of pcapng files.ntartest - a simplistic standalone pcapng (ntar) file reader.
