From an earlier post on freebsd-questions I added;

own bpf0 root:bpf
perm bpf0 0640
Sorry for leaping in, but I think you should change bpf0 to bpf only.
See below.
own bpf1 root:bpf
perm bpf1 0640
own bpf2 root:bpf
perm bpf2 0640
own bpf3 root:bpf
perm bpf3 0640
own bpf4 root:bpf
perm bpf4 0640
to /etc/devfs.conf. But I still get;
crw-r----- 1 root bpf 0, 11 Sep 22 21:14 bpf
lrwxr-xr-x 1 root wheel 3 Sep 22 21:14 bpf0 -> bpf
crw-rw-rw- 1 root wheel 0, 49 Sep 22 21:14 bpsm0
Looking at this listing, bpf0 is a symlink to bpf, thus
/etc/devfs.conf should manage /dev/bpf and not /dev/bpf0.
in /dev after rebooting. Do I require a statement in rc.conf or loader.conf
to activate more bpf devices? Am I editing the right file the wrong way?
The proper handbook chapter escapes me right now.
Previous to trying to build nessus from ports I built a new kernel with -
device bpf enabled.
Thank You,

I would suggest to get the package from tenable.com and install it via
pkg_add. That's how it worked for me but on FreeBSD 8.2-stable. Might worth a
shot.
Regards,
Trond.
Good Day;
Still no joy trying to build from source via ports or installing the
binary from tenable.com on FreeBSD 9. nessusd is installed but errors
out with 'libz.so.5 not found. I have;
$ ls -l /lib/libz.*
-r--r--r-- 1 root wheel 90328 Sep 26 05:46 /lib/libz.so.6
and
$ ls -l /usr/lib32/libz.*
-r--r--r-- 1 root wheel 90828 Sep 26 05:48 /usr/lib32/libz.a
lrwxr-xr-x 1 root wheel 9 Sep 26 05:48 /usr/lib32/libz.so ->
libz.so.6
-r--r--r-- 1 root wheel 76808 Sep 26 05:48 /usr/lib32/libz.so.6
and
$ ls -l /usr/lib/libz.*
-r--r--r-- 1 root wheel 126192 Sep 26 05:46 /usr/lib/libz.a
lrwxr-xr-x 1 root wheel 14 Sep 26 05:46 /usr/lib/libz.so ->
/lib/libz.so.6
on new world built last night.
From /usr/ports/security/nessus-libraries/files/README.bpf
"Nessus uses the pcap library, which uses the berkeley packet filter (bpf)
to do its job.
Since Nessus used multiple processes, several pcap-aware plugins will
need to access the the bpf at the same time.
This means that you need to recompile your kernel with the following option:
pseudo-device bpf
If for instance you want to have 10 nessusd running at the same time,
each running 5 plugins in parallel, you should create 50 (10 * 5) bpfs
(as nessusd is extremely lightweight, you can expect to have this amount
of processes running at the same time)
If you plan to scan a whole network, we recommand you create at least
100 of them.
Once your kernel has been rebuilt, get root, cd to /dev
and do:
./MAKEDEV bpf+100
For FreeBSD 5.x this is not needed since the devfs creates devices when
needed.
If you can not recompile your kernel, you can try to run the configure
script with the option --enable-bpf-sharing. In this case, nessusd will
try to share one /dev/bpf among multiple processes and do the filtering
in userland. NOTE THAT THIS OPTION IS HIGHLY EXPERIMENTAL AND WE DO
NOT RECOMMAND ENABLING IT."
Is this referring to an 8.2 system?
psuedo-device does not work on 9.0 kernel source.
Have not tried the MAKEDEV command yet because I do not know if I need
to continue since I cannot get the daemon to start.
Thank You,
Michael
