Here’s another challenge to test your bit wienie skills:
Write a tcpdump or Windump filter that will capture all traffic with a source IPv6 address of 2001:db8::10 through 2001:db8::20. Pretty easy, right? If you have not tried it, your going to find that tcpdump/Windump throws a few curves at you.
To check your work, here’s a capture file:
The file contains a mix of source IPv6 addresses. Obviously your filter should only display the specified range of addresses.
The winner gets to inspire awe and admiration in lesser geeks.
