Hi all, I''m having a hell of a time getting my IFB to work. I know I''ve done this before, so I''m missing something stupid. Can anybody tell me what it might be? Configs as follows: -------- #!/bin/sh modprobe ifb numifbs=1000 modprobe act_mirred modprobe 8021q brctl addbr br0 brctl setfd br0 0 brctl stp br0 off brctl addif br0 eth1 brctl addif br0 eth2 ifconfig eth1

Hi All, I''m using HTB to shape traffic, a little like this: tc qdisc add dev eth2 root handle 1:0 htb tc qdisc add dev eth3 root handle 1:0 htb tc filter add dev eth2 parent 1: protocol 0x8100 prio 5 u32 match u16 3000 0x0fff at 0 flowid 1:1 action ipt -j MARK --or-mark 0x01000000 tc filter add dev eth3 parent 1: protocol 0x8100 prio 5 u32 match u16 3000 0x0fff at 0 flowid 1:1 action

Hello, I''m using tc to limit the bandwidth of our wireless customers. I have a working script, but I''m not happy with it. I''m trying to write a more sophisticated script, but when I run it, it give me this error: RTNETLINK answers: File exists I have no idea what this error means or how to fix it. Here is a portion of the script (the whole script shapes several

Hi All, I''m trying to do some traffic shaping on an ethernet bridge. Currently, I have the following setup working: ifconfig eth0 down brctl addbr br0 brctl addif br0 eth0 brctl addif br0 eth1 brctl stp br0 off ifconfig eth0 0.0.0.0 up ifconfig eth1 0.0.0.0 up ifconfig br0 up This creates a bridge consisting of eth0 and eth1. So far so good. I now want to use tc to shape traffic

I am using a server with asterisk and I am trying to prioritize voip traffick -- I am a newbie at this traffic shaping, so please bear with me. I used the script below and what happens is thatall traffic in the bulk class stops after a couple of minutes. Also, should I include the ports for rtp in the filter statements with the ports 5061 and 4569? Note I have a fairly big pipe -- supposed to

Hi All , My first message and I have a little problem with my FC6 box trying to block emule traffic using layer7 . Here my network : Internet --------- ADSL Router ------------------- FC6 Box -------------------- Emule Box external ADSL : Dynamic Internal ADSL : 192.168.254.1 external FC6 : 192.168.254.3 internal FC6 : 192.168.253.1 Emule Box : 192.168.253.3 I guess that everything

OK, finally I have made cbq run ! now I would like to know if it is posible to limit a range of IP to a speed. something like this : from 192.168.1.1 to 192.168.1.21 limit to 128K I don''t whant to limit each IP to 128K, what I would like to do is limit all 20 IP to have a max of 128K. Is it posible?

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

hi all, Iam using the following CBQs to limit the FTP bandwidth pease tell what changes are rquired to make it work.... tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1:0 cbq allot 1514 avpkt 1000 bandwidth 100Mbit tc class add dev eth0 parent 1:0 classid 1:1 cbq allot 1514 bandwidth 100Mbit rate .4Mbit weight .4 prio 2 maxburst 20 cell 8 avpkt 1000 tc class add dev eth0

Hey all, I had asked a question a little while ago about CPU usage being outrageous while using tc and a cbq qdisc. Ed was very kind and offered a few suggestions. One of these was to look at hashing. So after pounding away at it for about a week, I have a general understanding of how it works and have tried to implement it. Unfortunately, and quite obviously since I''m posting here, it

Hi all, I''m sure I''m soing something wrong here. I am trying to set up a rate limit inside another rate limit. eg. I have a 512K rate limit on a particular VLAN. I am using an IFB so that packets passing through the bridge are counted at each port.(ie the throughput is limited to 512K, not just the traffic in one direction.) This part works OK, but I also want to limit a

Hi,All I am using iproute2 to manage bandwith for ADSL router.High,medium,low priority are needed for different protocol port on the ADSL's upstream side,as following: LAN --- |ADSL Router|------WAN When there aren't traffic on the specific priority, its bandwidth should be borrowed by other priorities.But it doesn't work.Here is my script: /usr/sbin/tc qdisc del dev nas0 root

Hi All, I found 2 unusual behavior with u32 classifier in Kernel 2.4.12. I’ve u32 compiled as module. 1> u32 filter seems not working if there is already some fw filter used for some other class. In order to get u32 working I’ve to delete root class, which in terms delete all fw filters too, and then same command for u32 works. fw is also compiled as module. 2> If I add u32 filter to my

Dear members I''m new to this list and also new to tc command.

Hi all. I fear I''m slightly offtopic with this question, but I''ll keep it short: who is (or feels) responsible for the #lartc irc-channel in oftc.net? I''d appreciate if that person would get in contact with me (off-list) in order to discuss some ideas I have. Thanks in advance.
