IPv6 Traceroute faker

This script will allow you to create a fake IPv6 path. It will reply to ICMPEchoRequests with the appropiate source address and TTL exceeded messages.

This allows you to broadcast a message to the world through your reverse DNS entries :-)

Install:

sudo apt-get install python-scapy libnetfilter-queue-dev python-nfqueue
sudo ip6tables -t raw -A PREROUTING -d 2a02:898:52:666::/64 -j NFQUEUE --queue-num 0

Edit the values at the top of the script to reflect your prefix and destination!

Route the subnet to your linux machine which runs the script and launch it:

sudo python ./ipv6-traceroute-faker.py

test with:

$ sudo traceroute6 -I $ipv6_destination
$ mtr -w -r -c 1 $ipv6_destination

Example:

(Example is outdated, I now work for another employer ;-)
