tcpflow and lo0

[Ksenia Marasanova]

Hi list,

Just want to make sure this is not a FreeBSD issue:
Is anyone using tcpflow to sniff packets on loopback interface? When I 
try

# tcpflow -c -v -i lo0
(-v to get all possible debug messages)

and then ping localhost for example, I always get:

tcpflow[31634]: warning: received non-AF_INET null frame (type 33554432)

I am using FreeBSD -stable.

Thanx
Ksenia.
