A friend of mine sent in a script that worked for him. <\/p>\n

I still couldn’t get this to work on my Ubuntu box. However in a later chat with my colleague Elphine I found out that Ubuntu had it’s own package for scapy. So I used apt-get to install scapy and this time it DID work. This is great since now I can start sticking objects into a database and move on to the next task of combining arbitrary traceroutes for the purposes of making graphs. I’m still curious why this didn’t work when I simply downloaded the scapy.py code and executed it. Once I get some working code I’ll post it here.<\/p>\n","protected":false},"excerpt":{"rendered":"
