   4 # Unfortunately, Mac OS X's devfs is based on the old FreeBSD
   5 # one, not the current one, so there's no way to configure it
   6 # to create BPF devices with particular owners or groups.
   7 # This startup item will make it owned by the admin group,
   8 # with permissions rw-rw----, so that anybody in the admin
   9 # group can use programs that capture or send raw packets.
  10 #
  11 # Change this as appropriate for your site, e.g. to make
  12 # it owned by a particular user without changing the permissions,
  13 # so only that user and the super-user can capture or send raw
  14 # packets, or give it the permissions rw-r-----, so that
  15 # only the super-user can send raw packets but anybody in the
  16 # admin group can capture packets.
