Using ngctl as suggested in the "All About Netgraph" Daemon News
article (http://people.freebsd.org/~julian/netgraph.html ) by Archie
Cobbs I get the following output:
[EMAIL PROTECTED] nghook -a fxp0: divert
nghook: can't connect to node
[EMAIL PROTECTED] ngctl list
There are 1 total nodes:
Name: ngctl4352 Type: socket ID: 00000005 Num hooks: 0
According to the article my four Ethernet interefaces (see ifconfig output
below) should display
as persistent nodes. Any reason why they do not appear? I compiled a custom
kernel on two separate
occasions, first to support IPFW/Dummynet, then later, Netgraph.
Thanks,

##### kernel options added for 1st compile (IPFW)
options BRIDGE
options IPFIREWALL
options IPFIREWALL_VERBOSE
options IPFIREWALL_VERBOSE_LIMIT
options DUMMYNET
options NMBCLUSTERS
options HZ=1000
##### kernel options added for 2nd compile (NETGRAPH, plus forgot IPDIVERT in
1st compile)
options IPDIVERT
options NETGRAPH
You need to also compile in or load the nodes you need.
options NETGRAPH_ETHER (I think)
(I forget the names.. look in LINT)
or
kldload ng_ether to load it dynamically
also, there is no "divert" hook for ng_ether hooks.
hooks for ng-ether are:
lower (to get incoming packets and accept outgoing packets )(connects to
the physical interface)
upper (to get outgoing packets and acceept incoming packets)(connects to
the protocol mux/demux)
orphan (above the protocol demux. only gives you packets that would
otherwise have been
discarded due to not being a known protocol.)
man 4 ng_ether
