similar to: problem with prio qdisc and tcng

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

Hi, I try to shape my incoming traffic. I have 2MBit/s DSL bandwith and the following ruleset (on the internal interface): $INT="eth1"; $INT_NET=192.168.1.0; $MAX_IN=2Mbps; dev $INT { egress { class (<$int>) if ip_src:24 == $INT_NET; class (<$ssh>) if tcp_sport == PORT_SSH; class (<$smtp>) if tcp_sport == PORT_SMTP; class (<$http>) if

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

Hey people, I have the following tcng configuration: #include "fields.tc" #include "ports.tc" dev "eth0" { egress { // Voice traffic class (<$voice>) if udp_dport >= 20000 && udp_dport <= 23000; // SSH connections class (<$interactive>) if tcp_dport == PORT_SSH; //

Thank you for your help. It generates this script : tc qdisc add dev eth0 handle 1:0 root htb default 2 tc class add dev eth0 parent 1:0 classid 1:1 htb rate 75000bps ceil \ 75000bps tc class add dev eth0 parent 1:0 classid 1:2 htb rate 125000bps tc filter add dev eth0 parent 1:0 protocol all prio 1 u32 match u32 \ 0xa000001 0xffffffff at 12 classid 1:1 But I thought it was necessary to

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,

Hey all, i have a class. class ( <$call1> ) if ip_dst == 10.100.1.6 && tcp_dport == 22 if ip_src == 10.100.1.4 && tcp_sport == 22 ; Now when i apply this traffic TO 6 on port 22 is indeed limited to the speed i specify BUT it doesn''t seem to take the src into account at all. If i change the src to anything, even an address that

i am trying to do some traffic classification using the PRIO qdisc and i am having a few problems. I have a root htb class: tc qdisc add dev imq0 root handle 1: htb default 255 r2q 1 tc class add dev imq0 parent 1: classid 1:1 htb rate 768kbit and a child PRIO tc class add dev imq0 parent 1:1 classid 1:99 htb rate 96kbit ceil 600kbit prio 0 tc qdisc add dev imq0 parent 1:99 prio tc filter

Hi, I have a router/firewall running Linux (like the most of you) and I wanted to do some traffic control. I''ve created an root PRIO qdisc like the example in paragraph 9.5.3.1 (http://www.lartc.org/howto/lartc.qdisc.classful.html#AEN903) with three SFQ child-classes. I wanted for interactive (ssh, telnet, ftp-control) and dns-traffic to be placed in the first queue, http should go in

Hello mailing list, i stand bevor a mystery and cannot explain it J. I want to do shaping and prioritization and I have done these following configurations and simulations. I can´t explain, that the combination of PRIO and TBF is much better than the HTB (with the prio parameter) alone or in combination with the SFQ. Here are my example configurations: 2 Traffic Classes http (80 = 0x50) and

Hi, I''m trying to use prio qdisc with htb, however not the "usual" way (like for example FairNAT). Here is my idea: Root has HTB shaping traffic to link speed -> then goes PRIO queues -> each prio queue has HTB with sublasses for each user, should look like this: 1: htb qdisc | 1:1 htb class

Hi, I have done this setup to give the machine 192.168.1.4 (masqueraded over dialup) the highest priority: #! /bin/bash WHAT="add" iptables -A PREROUTING -i eth0 -s 192.168.1.1 -t mangle -j MARK --set-mark 1 iptables -A PREROUTING -i eth0 -s 192.168.1.4 -t mangle -j MARK --set-mark 4 tc qdisc $WHAT dev ppp0 root handle 1: prio bands 3 priomap 0 1 2 tc qdisc $WHAT dev ppp0 parent 1:1

Hi, I have been modifying the Wonder shaper to include another queue. My understanding was packets would be de queued to hardware in the following order: cbq1 -> sfq10 > sfq20 > sfq30. Also we only move onto the next queue when the preceding one is empty. However is seems to be prio xx number that reflects the order packets are de queued not to what flowid they belong to. If I

Hello everybody, sorry for bothering you, but after some hours, I''m stuck. I''m living in a student''s foundation where I want to connect lots of people to a tiny DSL link. We have exactly four types of traffic. We want a really hard PRIO solution (as I promised to someone that group X will only use the link capacity which isn''t used by group Y). I could make a

Hi, We are using kernel 2.4.24, tcng version 10b. I''m trying to do some policing in the ingress queue of the internet device. Until now we had configured some filters dividing traffic into queues, and on these queues the Double Leaky bucket meter was applied. The idea is to have a minimum of bandwidth assigned per class (the cir values) and a maximum (pir values), just as with the

Newbie here... tcng version 10b I''m just learning about htb and using tcng. I am trying to make the example in Martin A. Brown''s Traffic Control with tcng and HTB HOWTO v0.5 example 2 /* * Simply commented example of a tcng traffic control file. * * Martin A. Brown <mabrown@securepipe.com> * * Example: Using class selection path. * * (If you are reading the

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 ) {

I thought I had this all worked out, but it seems not. The following tc configuration: tc qdisc del dev ppp0 root 2> /dev/null > /dev/null tc qdisc add dev ppp0 root handle 1: tbf rate 120kbit burst 1200 limit 1 tc qdisc add dev ppp0 parent 1:1 handle 2: prio bands 3 tc qdisc add dev ppp0 parent 2:1 handle 10: sfq perturb 20 tc qdisc add dev ppp0 parent 2:2 handle 20: sfq perturb 20 tc

Hi, I am new to traffic control in linux. However, i have able to grab many new knowledge in recent days. I find tcng somewhat easy to use (although lack proper doc. of its usage). I want to control traffic of several IP Addresses connected to my LANSIDE. What I want is , i want to separate certain bandwidth to all my clients. dev "etho" { htb() { class ( rate 400kbps, ceil

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
