Hello all,

I'm having an issue attempting to get the log_packets.sh script from squil
capturing traffic with 2.6.  Essentially whats happening is if I use a BPF
filter to capture traffic, but whether I use the log_packets.sh script or
fire off snort manually using the syntax below I see no traffic at all
either logging to file or printing to screen:


/usr/local/snort2.6/bin/snort -v -i eth1 net 10.0.0.0/8

While:

/usr/local/snort2.6/bin/snort -v -I eth1

Rifles through tons of traffic.

Is BPF filters broken?
