#! /bin/sh # # Unfortunately, Mac OS X's devfs is based on the old FreeBSD # one, not the current one, so there's no way to configure it # to create BPF devices with particular owners or groups. # This startup item will make it owned by the admin group, # with permissions rw-rw----, so that anybody in the admin # group can use programs that capture or send raw packets. # # Change this as appropriate for your site, e.g. to make # it owned by a particular user without changing the permissions, # so only that user and the super-user can capture or send raw # packets, or give it the permissions rw-r-----, so that # only the super-user can send raw packets but anybody in the # admin group can capture packets. # chgrp admin /dev/bpf* chmod g+rw /dev/bpf* |
