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

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 ) {

... 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, respectively

... 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. Complete list

... 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 - f_fw,

Help! I can''t get TCNG to compile!!! It did this on 2 different machines!

Hi all, this is really not really very easy to understand, or, to get in. Well, I''ve the following configuration on the router box: LAN - interface: eth0 - network: 192.168.2.5/24 - bandwidth: 100Mbit/s INET interface - interface: ppp0 - network: .dynamic.ip./0 - bandwidth: DOWN=1536kbit/s and UP=256kbit/s the LAN interface is to serve 6 other clients with internet and

FYI, i''ve just created a quick patch adding esfq (Enhanced Stochastic Fairness queueing discipline) for tcng (Traffic Control Next Generation). Patch is located at http://devel.dob.sk/tcng+esfq. Enjoy. Sam

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)

Hi I''m completely stuck with the tcng language - I assume there must be some way to arrange queues hierachically like eth1 | TBF | PRIO / \ class class but my attempt (below) produces a "inferno.tc:8: qdisc "tbf" has no classes near "prio"" when run through tcc. dev eth1 { egress { tbf (rate 128kbps, burst 64kb,

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 eth1 and

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

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 cburst 1839b Sent

I am working on traffic shaping using the nextenso proxy platform(a product of alcatel)on linux platform, I wish to do dynamic traffic shaping means on a fly, is that possible with TCNG??

Thank you for your help.

I''m trying to do some very simple rate-shaping on an interface. I want to limit my 100baseT interface to 7 megs both ingress and egress of the interface. I''ve been hacking my way through the documentation and some examples and I''ve come up with the following configuration for tcng that seems to do what I want. I''m curious if some of the other experts out

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 what''s happening, I''m marking the packets (right now, I''m using ipp2p as Klaus adviced me to) with iptables, and my queue rules are made using tcng, I''m using the HTB qdisc, and traffic is going to the HTB class
