If you are a DPI/IPS/Firewall/Anti-something-or-the-other geek, here's what you have to do to go from a piece of content (malware, pdf, image exploit, etc) to a packet capture: - set up a server - configure it to either post or download the content - use a client to generate the traffic - capture the packets - and then forget to pass "-s 0" to tcpdump *argh* - now repeat, rinse for IPv6 No more. Point your browser to http://www.pcapr.net/caprmakr (login required), upload a file and embed it into HTTP or SMTP streams. The generated pcap? Yours to keep, forever. See http://www.pcapr.net/view/kowsik/2009/1/1/22/adobe-acrobat-jbig2-buffer-overflow.pdf.pcap.html for what's possible with Cap'r Mak'r. Enjoy! K.
