Yes.

You need to be able to read from the bpf device, so either change the 
owner to be your username or group to be a group that you're in and give 
read permission to that.  I've always preferred the letter syntax: chmod 
u+r /dev/bpf* gives user read permission without changing the other 
permissions (that's chmod 400 /dev/bpf* for an absolute user read only / 
no access for others for the octally inclined).
