Hi there! Some questions I couldn''t find an answer for: IPtables: - Is it possible to filter those ACK-packets (to eleminate problems with ADSL-connections) with IPtables? It wasn''t possible with IPchains, so u32 had to be used. Now there is this nice little --tcp-flags option. But I just don''t know if this is all I need. The u32 was checking for packetsize too. So if

What''s wrong... I have Celeron 633MHz nd 768Mb RAM. When I''m running my script everything is OK, but when I''m connecting Internet and LAN link computer is hanging. But when i dissconnect this everything is OK. I have 500 users, 1500 classes and 3000 filters. Is it normal? What should I do?

Hi Here is something that worked with with 2.6.10-1.771_FC2smp and stopped working when I upgraded to 2.6.16-1.2069_FC4smp. These are fedora kernels and the network controller is an Intel Gbit (e1000) running a 100 Mbps Full Duplex. Don''t know how or if this matters but the 2.6.10 kernel has CONFIG_X86_HZ=1000 and the 2.6.16 has CONFIG_HZ=250 The idea is to just shape to , say 2Mbit, a

On my debian woody (kernel 2.4.31) the tcpdump doesn''t work with imq0 devices. If I try to tcpdump imq devices there is no packet seen: [...] rt1:~# tcpdump -n -i imq0 Warning: arptype 65535 not supported by libpcap - falling back to cooked socket tcpdump: WARNING: imq0: no IPv4 address assigned tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on

After starting to shape local traffic now i am getting a lot of kernel panics in tcp_retransmit, so i decided to update my kernel from 2.6.17.14 to 2.6.21.1 , the problem is that after that i get: # iptables -t mangle -A POSTROUTING -o eth0 -j IMQ --todev 0 iptables: No chain/target/match by that name so i can not redirect ttraffic to IMQ device. and modules are loaded. - # lsmod Module

I''m just-so-fresh to the list, so hello everyone. I''m having a realy hard time with setting up very simple bandwidth management. What I am trying to do is setup a 10Mbit interface to send at only 1920kbit to most of the network (to make sure it hardly ever tops 2mbit). I did succeed with the ingress traffic... With egress however, I get very odd results at different speeds. With

Hi again, I was just looking around for ESFQ sources, and I see that the main site is down, and only has kernel 2.6.4 patches. Is ESFQ maintained? If so, where can I find patches for 2.6.10?

Hi If I use sfq qdisc on a CBQ class I get a lot of dropped packets and the backlog itr almost always to its full value: 128. From the HOWTO I understand that the queue is at 128 packets, and SFQ shows 128/1024 flows , but how can I increase that value ? I have tried ip link set txqueuelen but this only increases the tx queue on the interface. qdisc sfq d468: quantum 1514b limit 128p flows

Hi! I just recently entered the wonderful world of the so called "advanced routing" and decided to try and limit the bandwidth of a MASQed network here and ended up in trouble :(. The setup is (as far as I can tell) pretty straightforward. eth0 is connected to the "real" network with a proper IP, and eth2 is 192.168.10.x (the MASQed network). All of it is basicly right out of

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

When I try to put all incoming traffic to IMQ on PREROUTING I can''t discern traffic to LAN and traffic to server. When I try to put only INPUT traffic to IMQ... I can''t discern traffic from LAN and from internet. Help me plizz to put all incoming traffic to one IMQ device and all outcoming to other IMQ device and (it''s very important) discern traffic to clients and

I''m not a programmer per se (including C), but... I''d like to be able to give the define in sch_sfq.c (of, say, 2.4.20), SFS_DEPTH other values than 128 as an argument on the tc commandline. It could be powers of two up to 2^7 (128) as it seems that 128 is the current maximum. I''m a little anxious to ask the question "How do I do that?" ;-) Instead

Group, I am reading about tc (traffic control) and willing to get my feet wet. As requirement, there should be HTB compiled in the kernel. I grabbed a Mandrake 8.2 distro, and didn''t installed the kernel source. Anyone knows if the HTB is compiled in Mandrake 8.2, or point a way to find that out? I tried to read the /usr/src/kernel.xxxxx/.config file, but it doesn''t exists.

Hi all, I''m new to using iproute2 for traffic shaping but not new to Linux. Essentially I have a WAN between two cities that I stream audio over for rebroadcast. Since it''s all done live stability and prioritization is critical in staying on air for our radio broadcasts. My WAN is 1.5Mbit PVC within my provider''s infrastructure so I have an unencrypted direct

Hi, I am new to tc and have been reading quite a bit on how to set it up etc. Everything seems to be working fine, until I started scp-ing a large file over a low bandwidth connection as part of my testing process. Here is the setup: my pc --- bridge running tc/htb --- rest of network TC is filtering traffic from "my pc" and classifies it as 120kbit (see my script below). I then scp a

Hi, i''m running a Bridge/iptables firewall, with no tc filters configured CPU utilization barely reaches 1%, i had to rate limit one particular server outgoing traffic and setup a HTB scheme like this iptables -F PREROUTING -t mangle iptables -A PREROUTING -t mangle -p tcp -s 99.99.99.99 -j MARK --set-mark 2 tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 10: htb default

Hi All, I''m trying to create a contended section of bandwidth using IMQ. I have the imq0 device up and running, with traffic passing through it. Firstly, I need to throttle the entire device imq0 to 2mbit/s. I would then like to add throttle rules for individual IP addresses, allowing them to pass up to 512kbit/s each, as long as imq0 has not reached its 2mbit/s. The configuration

Dear all, I''m reading codes in sch_sqf.c in kernel 2.4 of Linux. I find I messed up with the concept of slot, bucket and hash tables. Could anyone explain the data stucture of the hash tables a little to me. Thanks very much. Best, Franklin BTW: I can not understand why the number of entries of dep[SFQ_DEPTH*] should be twice:( _______________________________________________ LARTC

Hi everybody, i am new to this list so dont blame me if i will talk about nothing.. At this moment i am experimenting with htb + tc u32 filters , the problem is that i want some traffic to be unshaped so i did this.. tc qdisc add dev eth0 root handle 10: htb default 20 tc class add dev eth0 parent 10: classid 10:2 htb rate 256Kbit THIS IS TRAFFIC I WANT NOT TO BE SHAPED tc filter add dev eth0

Hi folks. Let''s say I would like to make some bandwidth control on my network using HTB. I have 2 clients: PC1: 192.168.100.2 PC2: 192.168.100.3 Server: 192.168.100.1 This has 2 NIC''s eth1 is local and eth2 is connected to the internet. It could be nice to have a script, where you could specify, how much bandwidth you want for a specific host on a network, like, PC1 has
