Hi All, I''m trying to do some traffic shaping with IFB. I have installed Ubuntu 6.0.6 and upgraded to the 2.6.17.7 kernel. I have an ifb0 device. However, I think I may have the wrong version of TC installed, because it doesn''t like the ''mirred'' argument. What version of iproute should I be using, and how can I upgrade it? apt-get update iproute

Hi all, I''m having a hell of a time getting tc and IFBs to co-operate. I''ve copied the following from http://linux-net.osdl.org/index.php/IFB: -- export TC="/sbin/tc" $TC qdisc add dev ifb0 root handle 1: prio $TC qdisc add dev ifb0 parent 1:1 handle 10: sfq $TC qdisc add dev ifb0 parent 1:2 handle 20: tbf rate 20kbit buffer 1600 limit 3000 $TC qdisc add dev ifb0

Hi all, Can anybody tell me what the maximum number of handles are that I can use when setting up qdiscs and classes in tc?

Hi all, Further to my previous questions, I need lots of IFBs on this thing. I have configured IFB as a module, and issuing a modprobe ifb loads it, but only gives me 2 IFBs (ifb0 and ifb1). How can I get more? I''m probably looking at needing about 20 on this project. Regards, Leigh Leigh Sharpe Network Systems Engineer Pacific Wireless Ph +61 3 9584 8966 Mob 0408 009

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

Hi all, Is it possible to invoke an ebtables target from tc? Ie we can use the ''action ipt'' to invoke an IPTables target, but I was wanting to use an ebtables target instead. Is this possible?

Hi All, Is there any way to set the maximum latency on a cbq when it is overloaded? Or, for that matter, to query it? For example, I want to know how long (in seconds) a packet will stay in the queue before it is dropped, and I want to be able to adjust this figure.

Hi all, Is is possible to configure the u32 classifier to match on VLAN ID? Or any other bits in the 802.1 header for that matter? If so, can anybody tell me how? Or where to find out how?

Hi All, I need to do some tricky filtering stuff. Can anyone tell me if any of the following are possible? * match on a combination of firewall mark AND u32 criteria. ie. handle 6 fw AND u32 match ip src 1.2.3.4/32 - to match packets from 1.2.3.4 which have been marked elsewhere OR * to OR the values of u32 matches. Something like u32 match ip src 1.2.3.4/32 OR match ip dst 1.2.3.4/32 - to

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

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''m having some problems setting up qdiscs on a bridge.The config looks a little like this: ifconfig ifb0 up # Bring up the IFB for this bridge. tc qdisc add dev eth2 ingress tc qdisc add dev eth3 ingress tc qdisc add dev ifb0 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 cell 8 # Raw qdiscs on each bridge port tc qdisc add dev eth2 root handle 1:0 cbq bandwidth

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

Update to iproute2 is available. Most of the changes were to repair the things that broke with the introduction of the batch mode to the ip command. http://developer.osdl.org/dev/iproute2/download/iproute2-2.6.14-051107.tar.gz For info on CVS ans other info see: http://linux-net.osdl.org/index.php/Iproute2 Masahide NAKAMURA * Updating for 2.6.14 - Show UPD{SA,POLICY} message

In linux one can have several route tables. But how do I list the route tables? (and no ''ip rule list'' is not it) -- damjan | дамјан This is my jabber ID --> damjan@bagra.net.mk <-- not my mail address!!! _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

I''m looking for a program that will replace the automatic ARP table population by the Linux kernel. The daemon should fix the MAC <-> IP entry from the IP of the first packet with that MAC received. Is there anything like this? -- damjan | дамјан This is my jabber ID --> damjan@bagra.net.mk <-- not my mail address!!! _______________________________________________ LARTC

I need some suggestions, I want to limit the up and down bandwidth of PPPoE users that are terminated on a Linux router (kernel 2.6). What are my options, can I apply tbf qdisc on a ppp interface? That would limit the download, what about the upload? Any suggestions are welcome. -- damjan | дамјан This is my jabber ID --> damjan@bagra.net.mk <-- not my mail address!!!

Hi I have tried to compile tcng-9m using Linux SuSE 9.1 Professional on my Intel box but it doesn''t work as follows: Step 1 - Downloaded iproute2-2.4.7_now_ss020116_try-i386-2.tgz Step 2 - Downloaded tcng-9m.tar.gz Step 3 - Downloaded linux-2.5.4.tar.bz2 Step 4 - Source kernel 2.5.4 extracted to directory ~/tcng/tcsim Step 5 - Source iproute2-2.4.7 extracted to directory

Hi, Currently I use dual cpu xeon server x86-64 with hp enabled two intel Gbit Nics 82547 I have assigned every NIC irq to one phisical procesor but the two virtual procesors stay idle and are not used for ether routeing or shaping Is there a way to split work from two NICs on 4 CPUs ?

Is there any library that i can hook on at runtime in order to create a qdisc dinamically from a program or if i want to do this I have to call the "tc" command? The disadvantage of calling the tc command from a process is that it creates an other process and this slows things up. Marius
