Do you need help with web hosting of your PCAP files?
Feel free to e-mail firstname.lastname@example.org 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!
