Hi all,
I have a couple of questions regarding tcng behavior.
First - I want to mark TCP_ACK packets as high priority, a common case. I
figured the tcp_ACK rule in fields4.tc would be enough but I've come
across Jason Boxman's tutorial and he recommends using:
class( <$ack> )
if ip_len < 64 &&
ip_hl == 0x5 &&
(raw[33].b >> 4) & 0xff;
So basically the tcp_ACK rule doesn't work? Has it been fixed? Which way
is right?
Secondly - I was wondering if anyone is trying to use l7filter on a
bridging Ethernet setup. It looks to me like the packets don't get to the
iptables layer so whatever marking I do with l7filter doesn't affect
packets going through the bridge, only packets addressed to the bridge
itself (which I have given an IP so that I can run some other things on
it). Do I need to look into ebtables marking? I don't know if l7filter
works with ebtables anyway. Or am I doing something wrong? The system
I'm working with is running Debian sarge and kernel 2.6.14.4 with the
l7filter patch.
Thanks for any help.
James
