File format(s)?[edit]

This page is missing an overview of the actual file format. Listing programs that use it is useful, but a description of the format is also essential for a complete article. Also, I came here looking for info on incompatibilities between tools using pcap format (having just run into one). — Preceding unsigned comment added by StuartGathman (talkcontribs) 17:41, 10 December 2012 (UTC)

The library can, as of libpcap 1.1.0 (unfortunately, there's no WinPcap-release based on that or a later release), read two formats - pcap and pcap-ng, although it currently writes only pcap format (except on OS X Mountain Lion, which has extensions to write pcap-ng). The page could link to pages describing those formats, which would probably suffice.
As for incompatibilities, are you referring to incompatibilities in the processing of the low-level file format or incompatibilities in the processing of packet data, and, if it's the former (the latter are would be of scope for this page), what sort of incompatibilities have you seen, and have you reported them to the developers?

Merges[edit]

Should this page absorb the libpcap and WinPcap pages, with libpcap and WinPcap redirecting to pcap? Guy Harris 21:36, 5 November 2005 (UTC)

Done a while ago. Guy Harris (talk) 18:08, 12 May 2009 (UTC)

Pcap name[edit]

And what does PCAP mean? Packet Capturing Application Protocol????... anything ?

Packet CAPture. It's not all caps, so they're not initials. Guy Harris 15:51, 3 October 2006 (UTC)

Licenses?[edit]

The "Free Software Portal" link is present in this page. But, there's no information about the licenses of any of the softwares described, and, the "Free Software" category isn't present. What's the story? 198.49.180.40 (talk) 17:49, 20 August 2009 (UTC)

See the infoboxes I added to the article. (Short answer: BSD license.) Guy Harris (talk) 19:32, 31 October 2009 (UTC)
There are no references for the BSDL. The code itself and the project page tell nothing about terms of use, licenses for use of the Pro version are sold. Where is that information from? --Trac3R (talk) 10:40, 21 June 2011 (UTC)
The source code. See the copyright notices. Guy Harris (talk) 18:38, 21 June 2011 (UTC)

Cookie[edit]

In programs that use pcap section, the cookie link links to the food. I can't seem to find the page for the application. —Preceding unsigned comment added by 61.94.132.204 (talk) 09:31, 31 December 2010 (UTC)

That's because there isn't one. I got rid of the link. Guy Harris (talk) 13:21, 31 December 2010 (UTC)

Complexity[edit]

Why is it that I can never understand Wikipedia articles on (a) computing and (b) statistics? These articles are written in the most technical and obtuse language, clearly intended for someone in the field. I leave this article on pcap having even less of an idea about what it is than I had before I got here.... Sigh. 70.29.73.38 (talk) 04:41, 21 January 2012 (UTC)

PCAP is also a short term for Projected Capacitive[edit]

As Projected Capacitive becomes more and more applied in nowadays life (e.g. mobile phones, tablets, information directories, HMI), maybe we can make a difference here between Projected Capacitive in the Field of electronics and Package Capture in the field of computer networking. — Preceding unsigned comment added by 83.136.193.197 (talk) 07:50, 19 July 2012 (UTC)

I've added an {{about}} item at the top to send people to projected capacitance if that's what they're interested in (and fixed the redirection for projected capacitance to go to the section of the touchscreen page about projected capacitance, rather than just to the page).
