Yes I am sure. I am a good boy.

I think I know what is going on here. Problem is that before to be able to
launch this command I have to set up my interface. But I have NO ip
address!!! so I have to set up the interface without IP address. Question
is, how I do that? Doing this:

tomeu ~ $ ifconfig rl2 up
tomeu ~ $ sudo tcpdump -i rl2
tcpdump: WARNING: rl2: no IPv4 address assigned

So it seems that this is the solution.
