Comment 7 for bug 96753

For me, on the machine I'm testing this on, I have a wired interface defined in /etc/network/interfaces and a wireless interface controlled by networkmanager. When the only active interface is the one defined in /etc/network/interfaces, then scapy works fine. If there is no active interface or if the interface defined in /etc/network/interfaces is not active, it crashes as you all describe. It seems to me that there are two issues here:

1. Crashes when it can't find the network. This is clearly a "Bug" that should be corrected as unexpected input should not crash a program.

2. Doesn't work the network interfaces not defined in /etc/network/interfaces. I think that this is a feature request that those of you using scapy (I don't) should take to the upstream authors and ask them to include in a future release. Talking with them is MUCH more likely to get this added than filing bugs on Launchpad.
