History of Tcpreplay
Tcpreplay has a bit of a different history than most open source/free software tools available today. Different because, tcpreplay has had multiple authors, some of whom have never even communicated over email.
Tcpreplay has had quite a few authors since it was first released back in 1999. One of the advantages of the BSD and GPL licenses is that if someone becomes unable or unwilling to continue development, anyone else can take over.
Originally, Matt Undy of Anzen Computing wrote tcpreplay. Matt released version 1.0.1 as part of the nidsbench toolkit sometime in 1999. Sometime after that, Anzen Computing was (at least partially) purchased by NFR and development ceased.
Then in 2001, two people independently started work on tcpreplay: Matt Bing of NFR and Aaron Turner of OneSecure. After developing a series of patches (the -adt branch), Aaron attempted to send the patches to be included in the development tree Matt was maintaining.
Shortly thereafter, Aaron took over development. Since then, two major rewrites have occurred, and more then thirty new features have been added, including the addition of a number of accessory tools.
As of December 2013, Fred Klassen at AppNeta has taken over maintainer duties.
