similar to: TC and IPv6 filters

Hi Everybody! I need help! I''m doing a tc script with tc filters that have match the Type of Service field in the IP header. This is the script I am using to setup the filters. tc filter add dev $DEV parent 1: protocol ip prio $PRIO_CONTROL u32 match ip protocol 6 0xff \ match u32 00190000 00ff0000 at 0 flowid 1:10 tc filter add dev $DEV protocol ip parent 1: prio $PRIO_VIDEO

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();

I have tested Devik''s tc (103592 bytes) and 2.6.8 which I compiled. Both return "RTNETLINK answers: Invalid argument". Stephen Hemminger should be sent a patch that fixes this. An example that returns the above error message is: tc filter add dev eth1 parent 1: protocol arp prio 5 u32 \ match u16 0x0806 0xffff at -2 flowid 1:50 I''m using this because it works:

Hi, I want work out a GUI interface for htb and now here comes to the part about adding and removing classes and filters. Here is an example script. TC="tc" DEV="dev eth1" echo "Add root qdisc, default traffic go to 1:30" $TC qdisc add $DEV root handle 1: htb default 30 echo "Divide the traffic into different classes and levels" # -------- level 1

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, I am attempting to set up some simple outbound shaping following the LARTC HOWTO. The HTB qdisc seems to work as the documentation says, but my filters don''t seem to be working. All of the packets go to the default queue regardless of what filters I set, it seems. (according to tc -s qdisc show) I am trying to get this working on my openwrt box (whiterussian rc6), but when

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

I always took that as mandatory.

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

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

I am wondering whether the commands ''tc filter change'' and ''tc filter replace'' are working. Googling around revealed a few emails on the LARTC stating that unfoirtunately they do not work. A quick check showed that they are still not implemented (properly). Some propose a solution to build a second tree of filters and apply the 2nd one when a need for it

Dear List, I am a tc newbie, and I''ve been working through the LARTC HOWTO to try to understand how qdiscs, classes, and filters fit together. I was confused by the example in section 9.5.5.1 (see excerpt below). I thought that classes were could only be attached to qdiscs (classful ones). In the example, however, classes are being attached to other classes. Can anybody explain to me

I''m attempting to set up a hierarchy of tc qdiscs with filters, but the filters don''t seem to be working correctly.  I''m running iptables 1.3.5 with iproute 2.6.16.20060323 on a Gentoo 2.6.18 kernel.  The system takes all my tc setup, but does not filter packets as I am expecting it to based on my ruleset. My tc qdiscs and classes are added correctly and report as

I''ve done some tests with TC FILTER and his PRIO and think that is an error or OMISION on TC FILTER DOCUMENTATION from: http://lartc.org/howto/lartc.qdisc.filters.html#AEN1100 Let''s say we have a PRIO qdisc called ''10:'' which contains three classes, and we want to assign all traffic from and to port 22 to the highest priority band, the filters would be:

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''m trying to use HTB for IPv6 packets. In the LARTC archive I found a thread on this issue where a solution was described. The idea is to mark a user-defined chain then use the fwmark for filtering. However my attempt wasn''t successful. I''m thinking of trying my luck with the u32 filter. This is what I did, any comment is greatly appreciated. Thank you all. tc

Hi, I have problem with this simple script: #!/bin/bash if [ "$1" == "del" ]; then tc qdisc del dev eth0 root handle 1: htb default 10 exit fi tc qdisc add dev eth0 root handle 1: htb default 10 tc class add dev eth0 parent 1: classid 1:1 htb rate 800kbit ceil 900kbit tc class add dev eth0 parent 1:1 classid 1:10 htb rate 300kbit ceil 600kbit tc class add dev eth0 parent 1:1

hi, all i run the following scripts : tc qdisc add dev eth0 handle ffff: ingress tc filter add dev eth0 parent ffff: protocol ip \ pref 4 u32 match ip dst 10.0.0.1 flowid :1 my question is : can i know how many packets are matched by this filter? if i can , what should i do to get this counter value, then. thanks :) _________________________________________________________________ MSN

Hi. Is there anyone who has understood of how u32 nexthdr addressing is supposed to work? (including the "tcp/icmp/.." matches who implicitly uses nexthdr) From reading the kernel code it apparently is using the location set by "offset at", but this seems to only be evaluated on hash parents, and only for it''s children.. I.e. the logic for u32 filter rule

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
