Hi! I was updated kernel from 2.4.22 to 2.4.23 and now tc tools can''t correctly determine default (pfifo_fast) qdisc on interface: # tc/tc qdisc ls dev ppp0 qdisc pfifo_fast 0: [Unknown qdisc, optlen=20] but, if I assign f.e. cbq qdisc for some device all show correctly: # tc/tc qdisc ls dev ppp1 qdisc tbf 8009: rate 32Kbit burst 10Kb lat 1.5s qdisc cbq 66: rate 10Mbit

Hi all, I''ve done a search through the archives but I can''t find a cause/solution to this. I''m running a FC4 box with the stock 2.6.12 kernel and a FC2 box with a stock 2.6.9 kernel. I''m obviously using iproute2 and the patched tc. When I clear down the qdiscs with "tc qdisc del dev <DEV> root" I get the following in response to "tc

Hi, I have a cable modem with a bandwidth capped upload rate. I''d like to prioritize packets going outbound according to the TOS header of the IP field. I''ve read through the LARTC Howto several times, and I think I have a good feel for the information it it. It also seems that what I''m trying to do is pretty straight-forward and common. Unfortunately, the HOWTO

We just moved a user, who deals with a *lot* of data, to a new server, since his old NFS home directory was on a disk that had started showing problems. Now, i/o is about six times slower, my manager reports. After a fair bit of googling, I started looking at tc and ip, and found the following: from ip address show, first, on the old home directory server, eth0: <BROADCAST,MULTICAST> mtu

Hello Lartc Mailing List: Been working on something the last week and a half and ALMOST have it working.., just need a few pointers from the wizards on this mailing list to nail it. Ok, my setup is a hub and spoke arrangement, hub is Cisco 2821 with IOS 12.4. Spokes are ruggencom RX1000 routers, Debian based with the following versions installed: rx1000test:~# uname -a Linux rx1000test

Hello all, this is my first post here. Sorry for my english. Gentoo LAN router, 2.4.26-hardened-r2 There are 2 WAN links, one LAN link. I am doing some iptables/routing/tc magic in my scripts. What''s interesting is marking packets traveling from all IP''s in LAN. Interesting commands are: ------------- for ip in `seq 50`; do $IPTABLES -t mangle -A FORWARD -o eth2 -d

Hi, I posted this question yesterday on the Openvpn mailing list, with no response, figured I will ask here too. I have been using openvpn for quite a while, no major problems encountered. Now I need to allow the server to access the lan of the client, and I can not figure out the routing. This is what I have after the tunnel is brought up: SERVER (A.A.A.A) Arx:~# ip addr ... 3: eth1:

Hello I''m doing some qdisc programming and I want to get/read the current ingress rate from a kernel module I was wondering what is the most convenient of achieving this My idea is to load the ingress qdisc and the police filter if necessary. and modify the source to export a structure or function so I can read the ingress rate. How does this sound? Is there a simpler way? With

Hi, I need a help on Linux routing, if you have some sparse time. I''m based in Madagascar and my English is not good; so please forgive me. *What I want to come-up with: *My main goal is to download using two modems at the same time, and combining their bandwidth, but I have failed miserably. The reason is this: our country is still using poor slow internets, and I have seen on the

Thank you Andy! I did''t find why I could''t use the fw match in ingress. Now it works. Now I ran into another problem: When I try to add a pfifo_fast leaf qdisc dor htb classes it seg.-faults. Is pfifo_fast a special qdisc? I can succesfully add other type of qdiscs. I found that a similar problem was reported in february on a MIPS architecture. root@zefir:/usr/src# tc qdisc

Hi, After reading section 9 of LARTC it seemed to me that a pure TOS based QoS setup with be sufficient for a small newtork. Interactive packets could have the highest priority, second highest for DNS and small HTTP packets and lowest prio for all others. The advantage is that, the setup would be simply a couple of iptables lines, because the default pfifo_fast qdisc already implements

Hi there, I have two questions: 1) In the following setup: tc qdisc add dev eth1 root handle 1: htb tc class add dev eth1 parent 1: classid 1:1 htb rate 100Mbit tc class add dev eth1 parent 1:1 classid 1:10 htb rate 128Kbit tc class add dev eth1 parent 1:10 classid 1:11 htb rate 32Kbit ceil 128Kbit tc class add dev eth1 parent 1:10 classid 1:12 htb rate 32Kbit ceil 128Kbit I have observed

I had a linux wireless router. I would like to monitor the queue lengh of the wireless interface. By default, the wifi0 interface is with pfifo_fast qdisc which does not report backlog packet. I replaced pfifo_fast with pfifo: ''tc qdisc replace dev wifi0 root pfifo'' Then I use iperf to send UDP pkts faster than the interface can handle but when I read the qdisc, the result is

I''m working with LEAF boxes as gateway machines. I''m trying to implement Proxy-ARP to build a bandwidth manager for my network. I''ve gone as per the lartc howto to implement a transparent bridge in an existing network and plan to put in my tc script after this. I''m configuring the box as a standalone one before plugging it into the network. I''m getting

Hello, I am trying to revive an old linux server installation, which still has libc5. Sadly, most current software does not compile anymore on this system, including the tc utility. As with other tools (net-tools, coreutils, procps etc.) I tried to compile and statically link (LDFLAGS=-static) on a more recent linux machine and copy the static binaries over to the old machine. But no luck

I have a setup with two Internet providers. One circuit (net0 == eth1) is used primarily for employees and tunnels to other sites. The other (net1 == eth2) is for the production machines that customers access. Everythung works in teh sense that packets get to where they are sent (mostly) but I recently I had a sniffer on the system and noticed a problem I cannot solve. traffic coming in

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello! I have a problem with a duplicate route entry, when using a pre-installed route and automatic take-over by the "heartbeat" daemon, which adds an address and the kernel adds an route automatically. Maybe anyone has an explanation... > ip addr 1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue inet 127.0.0.1/8 scope host lo

someone recommended that i should give br0 the same hardware address as eno2. I did that, and restarted the vm, and it still does not work. Here is my current host interface config: ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft

Hi, I have a server and ten clients in a Gigabit network. The server has 125mbps network bandwidth. I want that the server has 40Mbps bandwidth reserved for client 1 (IP 192.168.5.141), and the rest bandwidth is for all other clients. My script looks like this (I use IFB for incoming traffic): #!/bin/bash export TC="/sbin/tc" $TC qdisc add dev ifb0 root handle 1: htb default 30

Hi folks, I read quite some posts about "Destination host unreachable" problems before, but none could help me to solve my issue. So here we go: This is what I am using: SUSE Linux Enterprise Desktop 10 SP1 - Current with all updates Network configuration of my dom0: foobar:~ # ip a 1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue link/loopback 00:00:00:00:00:00 brd
