IMPORTANT: Tcpreplay was not accepted as a mentoring organization to the Google Summer of Code for 2009. Of course if you are still interested in working on any of the ideas below, feel free to contact me via IRC or the tcpreplay-devel mailing list.

Google Summer of Code 2009

I'm inviting students interested in networking, security and the IPS space to work on Tcpreplay to join the  Google Summer of Code. Tcpreplay is written in C/C++, builds controlled via  Cmake and source control is managed using  Subversion.

Ideas

Enable sending traffic over wireless

Ticket: #378

Skills required:

  • C

Complexity: Low

Overview: Integration of the  Lorcon wireless frame injection library to allow tcpreplay to send frames directly onto wireless networks.

Mentor: Aaron Turner (synfinatic)

Scriptable Packet Editing Engine

Ticket: #98

Skills Required:

Complexity: High

Overview: The tcprewrite engine (libtcpedit) provides a lot of ways that users can edit packets. However, there are 100's of different protocols and adding support for each protocol in C is tedious and error prone. Users are constantly requesting support for new protocols and fields. Ideally, libtcpedit would allow users to express their desired changes using a DSL or using an embeded general purpose language like Lua or Ruby without the need for writing C.

Distributed Tcpreplay

Ticket: #382

Skills Required:

  • C
  • Network programming

Complexity: Medium

Overview: While tcpreplay is heavily optimized to run as fast as possible, there are limits to the amount of traffic that a single tcpreplay instance can generate. This project is to create a distributed traffic generation solution which allows multiple copies of tcpreplay running on multiple hosts to synchronize their traffic generation in order to reach higher packet rates then a single instance is capable of.

Graph pcap files

Ticket: #25

Skills Required:

  • C
  • Graphviz library or other graphing solution

Complexity: Medium

Overview: While tools like  Wireshark provide detailed decodes of individual packets, it does a poor job of giving a high-level overview of communications stored in a pcap file. This makes it difficult for users to use tcpprep to split traffic in order to test inline devices like firewalls, IPS's and routers. This project is to parse the L2-L4 headers and create a graphical representation of the flows between hosts.

Port to Native Win32

Ticket: #133

Skills Required:

  • C

Complexity: Medium

Overview: Tcpreplay is portable across most flavors of Linux/UNIX and on Windows platforms via  Cygwin. The goal of this project is to make Tcpreplay compile natively under Windows (XP/Vista) using MSVC++ Express 2008.
