tc filter not work, why?
I try to use tc on mips with linux-2.4.18 but the u32 filter dosn''t work I added htb qdisc to linux-2.4.18 and use it to limit the speed in LAN, it only work well on the default class, for example tc qdisc add dev eth0 root handle 1: htb default 10 tc class add dev eth0 parent 1:0 classid 1:1 htb rate 2000kbit tc class add dev eth0 parent 1:1 classid 1:10 htb rate 500kbit ceil 500kbit

Simple Rule to Cap P2P Uploads
Hi, I''m new at traffic control and was reading up on HTB and using it to put an upper limit on traffic. I have a 256k DSL with 64k upload (which translates to about 5/6KB uploads). The machine running the P2P applications keeps filling up the 64K so my browsing from other machines in the network ends up being very slow. Since there are several P2P applications, I wanted to set the

egress bandwidth not limited / limited extremely inaccurately
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

Divide bandwidth between 4 groups of ip with the same rate
Hello, I have begun to use the tc scripts since 2 weeks ago, so I am beginner. I am trying to divide my bandwidth in 4 independent ones. Each of these sub-bandwidths is assigned to 4 different groups of ip. Bandwidth sharing is allowed. I put a Linux with two Ethernet card between the router and the LAN. Eth1 is the card connected to the router and eth0 is the one connected to the LAN. My ISP

How to bypass traffic control for one IP
Hi all, i have a problem: i have an adsl modem that is connected to internet. I can''t manage this modem. Between my PC and the modem i have a linux firewall that make the NAT and the traffic shapping.

tc filter oddities
I shape my upstream cable link with HTB from a script. My voip traffic (from the 192.168.0.14 host) gets priority over everything else to the near-starvation of other classes; the rest of the traffic is split up based on some priority rules (qos, empty ack packets, etc). eth1 is the uplink I''ve been using HTB and fw marking for the job until recently, when I changed the queue structure

packet shaping bridge
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

marked packets end up in wrong class
Hello, I have recently started looking at tc and iptables. I have an htb-queue with two classes 1:10 and 1:20 where 1:20 is the default. Then I use iptables to mark all packets I send out on eth1. I then filter marked packets into class 1:10. I expected all packets sent on eth1 to end up in class 1:10, but some packets still go to 1:20. Did I do it wrong? Thank you for any help. regards, David

htb & bandwidth sharing
Hi everybody! I''ve been trying with htb and tc filter. It seemed to work fine, but after testing with ethloop I''ve realized that traffic is not being distributed through the leaves as I thought. When sending packets to 1:10 and 1:11 at the same time, there''s no bandwidth sharing. There''s no traffic through 1:11 until traffic through 1:10 has finished. Though

htb overrate with 2.6.16
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

EF & AF filters with HTB
Hello all, Please could someone help me with this, I have been trying for days to get this to work. I would like to have BE, AF & EF classes with HTB qdisc. I can''t find any scripts online where this has been done. If I enable this filter: #tc filter add dev eth0 parent 2:0 protocol ip prio 1 \ #tcindex mask 0xf0 shift 4 pass_on then BE & AF classification seems to be fine but

limit bandwidth per host question
EHLO tc gurus. New to traffic control. Unfortunately, the politicians here in Denmark have decided that a PC is the same as a television set - so anyone owning a PC and internet connection of over 255 kbit/s must pay DKR 2200/year = EUR 300 = USD 400 in television licence fees :-( This is a lot of money for poor students, so we want to offer the students the *option* of limiting their

HFSC and prioritization
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

Random Early Detection
I''m streaming audio over a WAN that is 1.5Mbit/s. The audio has to go both ways and can be over tcp or udp. The manufacturers recommend udp as it has less overhead but has a higher chance of dropping out. The audio requires 130-200kbit/s in each direction for a combined 260-400kbit/s. I have two transparent bridges on either side of the WAN to do traffic control. I split it so

Leaky bucket in TC
