Network Forensics Contest submission
Some time ago I mentioned the Network Forensics Puzzle. The contest is now over and since I didn’t win, I’ll publish my submission below – it was after all correct, but not quite what the judges were looking for (congratulation to the winner). After validating that the MD5 sum for the downloaded file matches the…

I mentioned some time ago the packetlife.net contest. I’ve remembered to check back for the answer, which can be found here. Basically, one of the OSPF fields is based on a timestamp. Very cool. Also, it shows how many equipments will break after the 18th of January, 2038 🙂

Because 13 is not a nice number :), and because the submission deadline for the two contests has passed, I thought I share with you my solutions (they are not guaranteed to be complete over correct for that matter): The Hitch-Hacker’s Guide to the Galaxy How did Zay Zeutrino gather the desired data to switch…
