I was just having a quick peek at how ipfw works in FreeBSD-4 for IPv6,
to see what's required for IP-Filter (hoping for a clean interface)
and the response is "sigh". The old ipfw mechanism needs to be
abandoned, IMHO.
For those that aren't aware, pfil(9) in NetBSD used to provide two

Hi ...
I want to read the status register of the lpt port in NIBBLE mode. I want to
do this wether there is a printer connected or not.
What would be the best way to accomplish this ??
Should I use the ppi0 device with the PPIGSTATUS ioctl call, because
if there is no printer connected I

The issue of one vs. multiple lists (per direction, interface,
protocol, you name it) has been discussed some time ago. For sure
multiple lists are a (minor, given that we can start the ipfw lists
with a few of "skipto") performance improvement over a single one,
at the possible price

Firstly, the cross-post to -hackers seems appropriate but
my apologies if it isn't.
I am now certain that there is a bug in ioctl() (at least for
setting the mixer).
This started out as an attempt to fix a bug in xmms, but making a
debug version of mixer(8) showed it to be affected the same
