tcng TCP ACK match
Hello.
I have been trying to duplicate these u32 matching rules using TCNG, but
without much success:
tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32\
match ip protocol 6 0xff \
match u8 0x05 0x0f at 0 \
match u16 0x0000 0xffc0 at 2 \
match u8 0x10 0xff at 33 \
flowid 1:10
Wondershaper 1.1a implements this and if I run it things seem to be shaped as
expected. But this TCNG

Simple HTB setup with tcng
Hello all,
I am trying to set up a simple htb based system, where packets with
source ip 10.0.0.1 should have their own class.
I plan to use tcng to set it up easier.
Is there something wrong in my tcng file ?
~/tcng$ cat htb
/*
*/
#include "fields.tc"
#include "ports.tc"
dev eth0 {
htb ( ) {
class ( rate 600kbps, ceil 600kbps )

tcng version 9b
... is on SourceForge, http://tcng.sourceforge.net/#src
This one fixes a really stupid typo causing tcsim''s tc to pick up
HZ from the environment where it''s being run, not the simulation
environment, which confused most rate calculations.
And if_u32.c now only emits hashes that will actually be used,
which should make tcc''s tc output a little less ugly.

tcng version 8z
... is on SourceForge, http://tcng.sourceforge.net/#src
Besides a bunch of bug fixes, this release also contains a
greatly improved version of the comtc utility that copies
comments from the tcng source to tcc''s "tc" output.
There are a few infrastructure changes to make comtc work
smoothly:
- tcc''s -E option is now called -Wexperror or -Wexppostopt,

tcng version 8w
... is on SourceForge, http://tcng.sourceforge.net/#src
This one has the first steps towards getting non-IPv4 classification
right:
- I''ve added fields for skb meta-data (meta_protocol, etc.)
- if USE_META_PROTOCOL is #defined (tcc -D... or tcsim -Xc,-D...),
ip_hdr and ip6_hdr check the protocol number
- if_u32 generates distinct classifier branches for each protocol

tcng questions: TCP_ACK, ebtables
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 &&

tcng/tc setup
Hi all,
Can someone please help with a tcng setup? I have played with tc and tcng in
the past, and now would like to get some serious rules in place. However, I
have a difficulty in setting them up.
My setup is as follows:
One machine working as a firewall:
eth0 is the interface connected to a 512K DSL line
eth1 is connected to a LAN
eth2 is connected to another LAN, a bit like a DMZ

tcng and ip_len
I can''t seem to match packets less than 512 bytes:
class( <$bulk> )
if tcp_dport == 81 && !( ip_len & 0xfe00 )
;
or
if tcp_dport == 81 && ip_len < 512
Both rules match any packet I send to port 81, even when the total IP length
is much greater than 512 bytes:
class htb 2:4 parent 2:1 leaf 5: prio 1 rate 8000bps ceil 24000bps burst 6Kb

tcng + esfq
FYI,
i''ve just created a quick patch adding esfq (Enhanced Stochastic

Generation).
Patch is located at http://devel.dob.sk/tcng+esfq.
Enjoy.

TC-ng questions/problems
Hi all,
We have 2 class C networks that are connected by a Linux router with the internet. We want to apply traffic control (bandwidth control). For that we wrote the tcc script below. We have 2 problems:
1. To establish a 2 megagit download we must actually set the value to 2500kbps. Is there a possible reason for that?
2. If we enable the WAN device we get very hight ping times (they change

Ok, earlier I post a message explaining my problem with HTB and layer7 (or
ipp2p), about not being able to shape the traffic. Well, actually this is
