Have We Missed Some PCAP Hive?
Please send an e-mail to < info [at] netresec.com > or tweet to @netresec if you know some additional PCAP resource available on the Internet.
Do you need help with web hosting of your PCAP files?
Feel free to e-mail < info [at] netresec.com > or tweet to @netresec if you have PCAP files that you would like to share with the rest of the world, but need help with web hosting. We can provide a home online for your datasets, no matter how large they are.
Why do we like PCAP files so much?
Because: PCAP or it didn't happen!
