Hi all,
I have a VirtualBox guest which is running FreeBSD-8.0. I compiled the kernel for this guest with the options NETGRAPH in /usr/src/sys/i386/conf/GENERIC. I did that because I expected I would see each Ethernet interface as a netgraph node. But ngctl showed nothing
$ ngctl
There are 3 total nodes:
Name: <unnamed> Type: ksocket ID: 00000008 Num hooks: 1
Name: ng0 Type: iface ID: 00000006 Num hooks: 1
Name: ngctl1633 Type: socket ID: 00000013 Num
hooks: 0
(doesnot contain em0, em1,..)
This is different from the output for my real FreeBSD host
$ ngctl list
There are 5 total nodes:
Name: re0 Type: ether ID: 00000001 Num hooks: 2
Name: ngctl15142 Type: socket ID: 00000006 Num hooks: 0
Name: vboxnetflt_re0 Type: vboxnetflt ID: 00000004 Num hooks: 2
Name: vboxnet0 Type: ether ID: 00000003 Num hooks: 0
Name: wlan0 Type: ether ID: 00000002 Num
hooks: 0
(contains re0, wlan0)
Why are they different?
Thank you for replies,
Regards,
