similar to: TC filter error

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

(using htb) I''m trying to learn tc filter and it seems the flowid parameter can only point to leaf classes. Actually, it can point anywhere, but it doesn''t seem to work unless it points to a leaf class. Is this correct? For example, I have this tree: eth0 | +------1:-------+ | | +------1:10 1:20 | |

Hey, I have a problem adding a filter matching anything, here is my setup: ############### tc qdisc add dev eth0 handle 1: root prio tc qdisc add dev eth0 parent 1:1 handle 10: pfifo tc qdisc add dev eth0 parent 1:2 handle 20: tbf latency 50ms rate \ 128kbit burst 256kbit tc filter add dev eth0 protocol ip parent 1:0 prio 1 handle 666 fw \ flowid 1:2 tc filter add dev eth0 protocol ip parent

hi all people, I''m using tc and htb to create classes and do some QoS , but i would like to know if i can do it: after to create the classes I need to create the rules using tc filter : tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip dst 10.0.0.0/8 flowid 1:10 ok, this rule works with all packets going to 10.0.0.0/8, but how can i write a rule using "!"

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 ] \

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, Is it possible to make a filter with tc which exclude an IP like iptables ?? ex: iptable -t mangle -A PREROUTING -i eth0 -d ! 192.168.1.222 -j MARK ... I try the ! with tc but it doesn''t work.

hi all friends has tc filter an priority of rules , like iptables, let me explain it : with iptables, when the packet find a rule to go, it doesnt see the rest of rules, and how is the behavior of tc filter ?? see it : one packet from 10.10.10.1:2421 going to 11.11.11.1:110 what rule above it will be shaped ?? 1 ) tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip src

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 working htb system with about 1000 users. Until now I reload all rules at change, but it take too much time to apply. I cannot delete applyed filters. There is rules for one user: #!/bin/bash -v # Download shaper EX -> 2:20 /sbin/tc class add dev eth2 parent 2:20 classid 2:1775 htb rate 8000Kbit ceil 10000Kbit quantum 1514 /sbin/tc qdisc add dev eth2 parent 2:1775 sfq perturb

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

When I run this: tc filter add dev eth0 parent 1: protocol ip prio 1 handle 1 fw I get: RTNETLINK answers: Invalid argument The traditional interpretation of that gnarly error message is that cls_fw is missing, but lsmod | grep cls_fw gets me: cls_fw 2336 4 (autoclean) I can''t remove it because it''s in use, but all 4 statements that use it failed, so

Hi, I have a problem with ''tc filter'' on a 2.4.22 kernel from Slackware 9.1 distribution. The tc command binary is from htb3.6-020525.tgz (http://luxik.cdi.cz/~devik/qos/htb) I''m trying the following command sequence: tc qdisc add dev eth0 root handle 1: htb default 1 r2q 1 tc class add dev eth0 parent 1: classid 1:1 htb rate 1200kbit ceil 1200kbit tc class add dev

Hi, I am currently working on the TC. I have seen some behaviour which seems to be odd. I know someone in the mailing list would have seen this problem or may have some fix for this problem. When I try to include u32 filters with different priority or pref, I could see the filters being set on all the priority''s irrespective of the priority number. See my sample script below and the

Hi I have been playing with tc. I''m using htb and sfq. I tried to setup shaping of every ip address within a /20. I found that there must be an upper limit of about 2096 on the number of rules (classes, qdiscs or filters). I was testing a /20 which gives 4096 classes, qdiscs and filters. I''m using hashkey to optimize processing of frames. When executing the script below - it

Hello! I was always using "default" in HTB to choose default class, but now I need to do it with filters. Tried following command: # tc filter add dev eth0 protocol ip parent 10: prio 2 flowid 10:2 Unknown filter "flowid", hence option "10:2" is unparsable It is from example in LARTC Howto. My question is then - how to make a filter matching all without eating

I have a requirement which I guess it is not too unusually, however I haven''t quite figured out how to do it and couldn''t find any examples which handle that. I have made myself a Linux-based bridge, eth0 bridged with eth1 to form br0. In this bridge, I run ''tc'' script to handle QoS. So far nothing unusual. However, what''s different is that this

Help me  ... I try use the tc filter, but seems he doesn''t work, I already reconfigured my kernel ( 2.4.32 ) with all options related a QOS enabled ( like modules ) and nothing happens. I get the tc tool from HTB source package, well  this is my set : eth0 is my internal NIC. tc qdisc add dev eth0 root handle 1: htb default 12 tc class add dev eth0 parent 1: classid 1:1 htb rate

Hi, I have recently started to use ''tc'' on ipv6 traffic and have come across an issue with tc filter. As per tc_filter.c in iproute2-050816, to match ''priority'' of an ipv6 packet, the u32 filter matches against the first 8 bits of the packet. From f_u32.c: if (strcmp(*argv, "priority") == 0) { NEXT_ARG();

Dear all, I have big question in my mind about "tc filter" sintax. If I give "tc -s -d filter sh dev eth0" command, then the output is like below : filter parent 1: protocol ip pref 1 u32 filter parent 1: protocol ip pref 1 u32 fh 800: ht divisor 1 filter parent 1: protocol ip pref 1 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:2 (rule hit 21553629 success 37907)
