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

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 some rules inserted in the NAT table dual SNAT and DNAT for a connection They use at some moment the same port of the outside network. The problem i have is that the connection tracking in the kernel checks first the oldest rule and then the newest one. I use a system based on ARM XScale processor. Is that the default behaviour and how can i change this behaviour? Marius

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

Hi Guys, I have a little problem i dont understand why its happening, Initially i thought it was a network problem, but then i made a crossover between me and the server and shaped on that interface with as minimal as possible config this my test: $TC qdisc add dev $INTERFACE root handle 1: htb default 30 $TC class add dev $INTERFACE parent 1: classid 1:1 htb rate 10Mbit # POOL1 $TC class add

helo again. I think this question i am asking is worth: we know that pppoe-server creates a pppX device on each connection done to it. So, when i have to shape, i have to shape each pppX connection device on itself alone. What i know is that the borrowing method on one device by itself, e.g. ppp0, alone using HTB or the like. this means that i have to create for another device, e.g. ppp1,

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

hi all. i am currently now serving PPPoE in my area. i had a script generated from tcng that worked perfectly before i started serving PPPoE. the issue is not in the script it self BUT in that "tc" code is not shaping on the ethernet anymore BUT INSTEAD on the pppX devices. I tested it and talking jargon, what should i do? The issue is that for each PPPoE login, PPPoE-server

Hi, I'm switching between two domains, and I need to make a couple of Linux+Samba machines provide the same shares in both domains. I've set up two sambas in the same machine, listening on different subinterfaces, but I can't make winbind to behave properly. As soon as I start the second winbind, the domain accounts provided by the first one become hidden (that is, 'getent

Hi, I''m trying to perform some (what I consider) basic traffic shaping on our network utilising HTB. I have mostly reused the example on the lartc.org site: tc qdisc add dev eth0 root handle 1: htb default 10 tc class add dev eth0 parent 1: classid 1:1 htb rate 100mbit burst 24k tc class add dev eth0 parent 1:1 classid 1:10 htb rate 50mbit ceil 80mbit burst 19k tc class add dev eth0

Hi I tryed to use a htb qdisc/class on top of another htb qdisc/class as you can see bellow: #!/bin/bash tc="/sbin/tc" $tc qdisc del dev eth0 root $tc qdisc add dev eth0 root handle 1: htb default 40 $tc class add dev eth0 parent 1: classid 1:1 htb rate 100Mbit burst 15k $tc class add dev eth0 parent 1:1 classid 1:10 htb rate 50Mbit burst 15k $tc class add dev eth0 parent 1:1 classid

Hi, I'm using Vlans in my network as a way of preventing pier to pier communication - I only want nodes in the network to talk to the gateway (a linux box). I have successfully set up lots of sub interfaces using the vconfig too, one for each vlan. What I would like to be able to do is remove the ip address from each of these subinterfaces eth0.x and bridge them to eth0. I have successfully

Hi everyone. I''m working on a problem since some days. I have a linux router with about 100 ppp interfaces. Each interface should bei limited to an individual bandwidth of 1024kbit, 2048kbit or 3096kbit. Up AND downstream. (let''s say for example 1024kbit upstream and 1024kbit downstream) The reason for this problem: I have to limit users to their booked bandwidth, because

My needs is limiting the outbound traffic of an smtp mail server. It is connected to a gateway via 100Mbit ethernet. I want limits its outbound traffic to max 3 Mbit. I have read lot of docs and tried various script without great results. Any simplest solutions? TIA. Regards, B.

we have an external 2Mbit dsl connection and running on it are several gre vpn tunnels so far i''ve given priority to the vpn traffic (using htb) can i now put rules in for the tunnels to control traffic within each tunnel (that''s where our video conferencing etc runs)? or can i only control the real interface (eth1 in our setup)? if not can i somehow see the packets inside the

Hello everyone, I''m a newbie experimenting with CBQ shaping and am facing a few problems. Can any of you please help?

OK, I''m stumped. I''ve read through most of the LARTC HOWTO and have yet to find a basis for what I need to accomplish. I have a Linux box that controls access to and from the Internet at my workplace. We have a number of remote employees that connect via PPTP and IPSEC to the office''s internal network. Some of these remote employees are currently using SIP phones.

As part of my initial KVM host on C8 deployment, I decided to set up some HA features on the new host, specifically NIC teaming. Teaming seems to be bond++ of a sort, so I thought I would at least try it.? So here's the scenario: 1.) Server with two gigabit ethernet ports, two Cisco switches. 2.) During install, used the 'Server with GUI' group and added the virtualization

Some of Shorewall''s features manipulate routing tables. Linux removes routes involving interfaces that disappear (namely pppX). When these interfaces are restore the routing tables are not restored. Just wondering how people are dealing with this situation.
