I shape my upstream cable link with HTB from a script. My voip traffic (from the 192.168.0.14 host) gets priority over everything else to the near-starvation of other classes; the rest of the traffic is split up based on some priority rules (qos, empty ack packets, etc). eth1 is the uplink I''ve been using HTB and fw marking for the job until recently, when I changed the queue structure

Since week i dig lists and www and can''t find solution for my problem. I''m using HTB 3.13 kernel 2-4-25 smp iptables 1.2.9. I''ve got situation like this: LAN------Linux Box(routing only)------- Linux

The interface is setup like this: # tc qdisc del dev eth0 root # tc qdisc add dev eth0 root handle 1: htb default 2 # tc class add dev eth0 parent 1: classid 1:2 htb rate 20mbit ceil 20mbit If I add a second class and a filter to send traffic to it like this: # tc class add dev eth0 parent 1: classid 1:130 htb rate 1Mbit ceil 1Mbit # tc filter add dev eth0 protocol ip parent 1:0 prio 130 u32

Hi all! :) I see that this is partially covered in the mailing list archive but at the moment I can''t find a straight & working answer. I have an imq device with dynamically attacched classes/qdiscs/filters. There is a hashing filter that maps the last octet of an user''s IP address to a class (and associated qdisc). The "empty" filter looks like this: filter

Hi all, Can you tell me where is the documentation for the new IFB (implemented in kernels > 2.6.16). Thanks in advance! Nikolay

Hi there good people, I''m a newbie in what concerns running Linux on machines other than desktops, so I need help from all you gurus out there :-) I have Linux installed on an old computer (Winchip C6, Pentium clone), acting as a router/firewall for two other computers. Both these machines are connected to the firewall via a dedicated ethernet card each, on different subnets,

PATCH 1 ======= On my machine tc does not parse filter "sample" for the u32 filter. Eg: tc filter add dev eth2 parent 1:0 protocol ip prio 1 u32 ht 801: \ classid 1:3 \ sample ip protocol 1 0xff match ip protocol 1 0xff Illegal "sample" The reason is a missing memset. This patch fixes it. diff -Nur iproute-20051007.keep/tc/f_u32.c iproute-20051007/tc/f_u32.c

Hi How can I control which filter a packet will meet first? I have tried changing the order of applying the tc filter scripts and switching flowid number, but ''protocol ip u32 match ip src <ip net> match ip src 0.0.0.0/0'' always kicks in first? >From my script -------------------- # All traffic - Priority: Low tc filter add dev eth0 parent 1:0 prio 2 protocol ip u32

Hello. I have a linux server connected to a gigabit lan, and though that lan to a 768kbps/768kbps DSL modem. I''m trying to shape my webserver running on port 80/443 down to 512kbps, while leaving all other ports alone. The current configuration script that I''m using is as follows: tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb default 99 tc class add dev

dear All, I'm a new student and my job is too shapping bandwith for our campus faculty network. I want to implement htb with Redhat-9.0 distro. does this distro kernel support htb and tc good ? or i should apply some patch or upgrade kernel ? regards reza

Hi folks. For quite a while, I tried to use linux (cbq and htb) to control bandwidth in order to replace a cisco equipment used to play this role on our network. After trying here and there, with a bunch of different distros, different versions, different compilations, ... the closest I could get was as follows: (using htb.init and cbq.init) Desired BW ==> Achieved BW 128k ==> 404.78

Hello I have few questions regarding tc functionality (qdiscs, classes, etc.) when vlans are in use. For example, consider interface eth0, for which I create and extra vlan with vconfig, let''s say eth0.11. Then using tc I can add usual things - qdiscs, filters, ... - to both eth0 and eth0.11. The questions are: - on which interface - virtual or real, should I actually use tc ? Or

Hi, How can I delete an existing filter? Is it possible? I tried different combinations of tc commands but, while manage to delete an existing qdisc or class, I wasn''t able to find a way to delete an existing filter. The tc man page doesn''t even list the del command in the synopsis. tc filter [ add | change | replace ] \ dev DEV [ parent qdisc-id | root ] \

Hi all. I''m going on my 3rd week trying to get a simple traffic shapping to work the right way :( !! My goal it to shape the traffic coming from one machine (pc1) to another machine (pc2) throught the "eth0" interface. My test configuration is as follows: PC1   IP: 192.168.105.237   Mask: 255.255.255.0   OS: Red Hat Linux Kernel 2.4.20-8   Rules:

Hello list, I discover strange behaviour of shaping traffic that i setup from Shorewall-4.0.2. I know that this is not Shorewall problem but may be somebody from list can help me or explain this situation. I have follow interfaces in 'tcdevices' files: #INTERFACE IN-BANDWITH OUT-BANDWIDTH # $EXT_IF 500kbit 248kbit $INT1_IF 500mbit

Hello, I use HTB with linux-2.4.20-ac1 and iptables-1.2.7a (pathced for IMQ). I configured one HTB qdisc on an IMQ device. This qdisc has some classes (about 5) and all of the classes has qdisc pfifo. I sometimes got out from my linux (while I was working) and I found in logs: Dec 4 11:49:27 core kernel: HTB init, kernel part version 3.7 Dec 4 11:49:28 core kernel: HTB: quantum of class

Hi All Can someone tell me what am I doing wrong? These was suposed to catch icmp type 8. Why ''match u8'' does not work? # tc filter add dev eth0 protocol ip parent 1: prio 2 \ u32 \ match u16 0x0800 0xffff at -2 \ match u8 8 0xff at 20 \ flowid 1:5 Illegal "match" # # tc filter add dev eth0 protocol ip parent 1: prio 2 \ u32 \ match

Hello, I have a linux box sitting between (and bridging/firewalling) 2 LAN segments. I''m using Bridge/Netfilter/IMQ/tc(htb) to control (shape) mail/web traffic that traverses the 2 networks. The networks also have some VLAN tagged traffic flying around. My linux box behaves OK with VLAN traffic except that the shaping doesn''t seem to work. Normal http shapes alright but as soon

Hi, I am very new to tc. I added a filter using the following command: tc filter add dev eth0 V parent 20:0 protocol ip prio 1 handle ::128 u32 match ip tos 0x44 0xfc flowid 20:1 To check if the filter rule was indeed added, I run tc filter show dev eth0 parent 20: This gave me the following output: filter protocol ip
