Finding Pcap Files
There are a few sites which have repositories of pcap files. If you know of any more, let me know.
- Wireshark sample captures
- pcapr - A new pcap sharing site currently in beta with over 1,200 different packet captures!
- PacketLife - A website all about networking and protocols
- OpenPacket.org - Pretty much defunct now
- DefCon 17 CTF - 7.5G uncompressed. See DC17 for more info.
Tools Using Tcpreplay Code
If your application is utilizing code from Tcpreplay (which is not only allowed, but encouraged by it's author as long as you follow the terms of the license) let me know and I'll list your project here:
- SIPp SIPp is a free Open Source test tool / traffic generator for the SIP protocol.
This product includes software developed by the University of California, Berkeley and its contributors.
