Even on a i386 machine for a very simple qdisc i get this error answer: RTNETLINK answers: Invalid argument what are the options in the kernel that i have to choose to escape this error? I really know nothing about netlink sockets, what they are, where they are in the kernel, what should i do. please help. Thank you in advance, Marius Corici

hello, i have a 5500 iPaq with familiar 0.8.2 on it and i don''t know how to install a traffic shaper tool on it. I installed iproute2 package i found on familiar site and for that i have the tc and ip commands, but when trying to add a qdisc, as a dummy example, i get the next answer: > tc qdisc add dev wlan0 root cbq bandwidth 100Mbit avpkt 100 RTNETLINK answers: Invalid argument

Hi. there is a way to MARK udp VOIP (SIP) traffic, in order to put in a highest prio class ? Traffic flow seems start on udp 5060 port, but next both server and client seems jump to a random(?) port. I can''t use CONNMARK because is udp traffic. I only see a pattern for L7 patch in order to SIP traffic identification , but I run 2.4 kernel series . When you patch 2.4 kernel with

I''ve applied julian''s paches to a 2.6.14 gentoo kernel with the appropiate options enabled, and i''m using a modified version of the mpath2.sh script also available on julian''s site http://www.ssi.bg/~ja/ Overall everything works nearly perfectly. Incomming connections to either the fios (PPPoE) connection, or cable modem get routed back out correctly. The

Could whomever is in charge of the lartc mailing list please change it to add the header: Reply-To: lartc@mailman.ds9a.nl Every other list I''m on is setup so that by default replies will go to the list.

I have a router with only one physical ethernet cable. I know it''s stupid, but it is the network I have to use for a demo. I have in mind to construct an HTB class tree for some network limitations for the outgoing traffic. The question is: can i use the HTB class mechanism on 2 subinterfaces of the same physical network card without any interference? Please let me know as soon as

Hi all, based on the information in the "Linux Advanced Routing & Traffic Control HOWTO", I was trying to set up traffic shaping on my firewall. While I found the HOWTO very useful, in the process I ran into some problems that I did not forsee: According to the HOWTO it seems that it should have worked, even after spending some time going through the sections looking for answers,

Hello I am using htb (krenel 2.6.14.3 + esfq patch from fatooh.org) to limit the bandwidth. But I want the absolute maximum rate to be for example 5Mbit and not to exceed it. here is the script: $tc qdisc add dev ${NETIF} root handle 1 htb r2q 4 $tc class add dev ${NETIF} parent 1: classid 1:21 htb rate 5Mbit ceil 5Mbit $tc class add dev ${NETIF} parent 1:21 classid 1:101 htb rate 2Mbit ceil

Hi, I''ve failed miserably in my endeavours so far and I''m at the point where help would be much appreciated. I want to have 3 bandwidth limited classes on my Internet interface. In each of those classes I want 3 prioritization bands, and then use "tc filters" to place the traffic into the correct class and priority. The problem is that the traffic

Hello all, I''ve been trying to test HTB performance for different link bandwidths to find potential limits and this is what I have so far: http://home.comcast.net/~msethuraman/htbtest/ Can members please go over the setup, test procedure and the results and answer a few questions? 1. Is the testing methodology okay and can the results be considered accurate? If so, is this a decent

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

I''m using HFSC to limit bandwidth for our wireless customers. However, I''d also like the bandwidth prioritized based on packet type. This is what I''m trying right now, and I''d just like some input from anyone out there knowledgeable in this on whether it does what I want it to do: Eth1 -> HFSC ........|-> HFSC (User1) (Min 512 Kb, Max 1024 Kb, Burst 1536

hi all what does it mean if the total network speed on internal LAN is greater than the external LAN and why it happens? the extrnal LAN here is the Intenet using a dedicated bandwidth. and BTW the linux box NATting has no shapping at all. just direct piping

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 all, I just recently began using HTB to try and manage bandwidth for my network.

ehlo list, I''m willing to shape ppp users e.g. each pppX interface to get XXX kbits I classify traffic going to ppp+ interfaces like this: iptables -t mangle -A POSTROUTING -o ppp+ -j CLASSIFY --set-class 0002:0020 then i have a file which is executed when a ppp inteface is up and first argument parsed to that file ($1) is the ppp number (e.g. 35 for ppp35). it generally looks like
