similar to: tc filter not work, why?

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. I have create a script that limit the bandwidth of the "external" interface of the firewall so i can manage my bandwidth for my internet application. The problem is that i need to

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

Hello, i try to use iptables to mark packet and then to filter them with tc. Here is my script: iptables -t mangle -A PREROUTING -s 172.28.54.41/32 -p tcp -j MARK --set-mark 1 tc qdisc add dev eth0 handle ffff: ingress tc filter add dev eth0 parent ffff: protocol ip prio 1 handle 1 fw police rate 10000kbit burst 10000kbit mtu 1500k drop flowid :1 I can not use u32 because i have several

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

Looking for some advise from the experts out there. We do simple traffice shaping and I''m having trouble figuring out how to shape vpn traffic using a tc filter. The following filter works fine for SSH tc filter add dev eth2 parent 1:0 protocol ip u32 match ip sport 22 0xffff classid 1:10 The following throws and "Illegal match" error when trying to filter GRE traffic. tc

Hi, I am new to this group. I use this script tc qdisc add dev eth0 root handle 1: htb tc class add dev eth0 parent 1:0 classid 1:1 htb rate 500kbit ceil 500kbit tc class add dev eth0 parent 1:1 classid 1:2 htb rate 300Kbit ceil 500kbit tc class add dev eth0 parent 1:1 classid 1:3 htb rate 200kbit ceil 500kbit I like to know: If two customers of the same class (for example 1:2) work

Hi folks, I`ve a problem to use HTB and SFQ. The first script, below, to show a simple configuration, does work fine...!!! But, in the second example, does not work, becouse i put more code to clasify the traffic by protocol, http and ftp in this case. Somebody can tell me the errors? Thx, in advance.- NOTICE: IMQ device is to asociate with ETH1 my external iface. SCRIPT que funciona:

If I try: @article.article_groups.delete_if {|x| x.group_id == x.group_id } It does nothing. If I try: articletmp.article_groups.each{ |x| @article.article_groups.delete(y) } It deletes some of the groups. @article.article_groups.clear works. Why dosn''t the to first examples work as expected?? Do I have to put groups I don''t want to

Hello, I''m using a script with tc, to limit my outgoing traffic : tc qdisc add dev eth0 root handle 1: htb tc class add dev eth0 parent 1: classid 1:1 htb rate 500kbit burst 6k tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip dst 172.28.54.9 flowid 1:1 I want to test bandwidth with iperf to see if limitation is correct. Sometimes, I get correct measure for certain rates,

Hi! I recently changed my qdisc from CBQ and PRIO to only HTB, and I can''t really seem to get the rates to work as I want them to. I have eight classes, which I set up as follows: tc qdisc add dev eth1 root handle 1: htb default 122 tc class add dev eth1 parent 1: classid 1:1 htb rate 1000kbit ceil 1000kbit cburst 1500 burst 50kb tc class add dev eth1 parent 1:1 classid 1:11 htb prio 0

I am trying to do ingress flow control with htb + imq, and as could be expected it isn''t working well. It works a lot better when I keep the htb ceiling well below what the link can actually carry - I guess because htb gets to throttle the TCP fast start before it causes packets to be dropped. The only problem is wasting all that bandwidth hurts. It occurred to me that the bandwidth

Hi everyone, I''m new to tc but I need to use it to set up shaping on a new NAT box. In short: Each user must have their upload limited to 128kbit and downlink limited to 256kbit. Global bandwidth to be limited to 100Mbit Interactive packets to have higher priority 200+ users, so need to match packets fast So far I have managed to get the download limits working. However I need to

Hello, I''m trying to configure several wireless routers with QoS support. The idea is to implement differentiated services so that VoIP traffic gets the maximal priority, then video, control traffic, interactive data traffic and best-effort traffic. I have seen that CBQ used to be chosen as qdisc for implementing bandwith share in DiffServ but now HTB is preferred because it is

Hi, I wanted to implement some QOS on my Linux Box with HTB, but after some time spend on the configuration and tests, I still don''t manage to have some correct results.

Hello everybody on the list, I have the following situation where I want to police the speed of incoming packets from specific subnets to 1024kbps and then police all the rest to 256kbps, which is the speed my ISP grants for the rest of the internet. So, eth1 is the one connected to the cable modem and then to the internet. I do: tc qdisc add dev eth1 ingress handle ffff: then: tc filter

I have voip quality issues I would like to minimize. I have a ~= 3M/384k (Comcast) cable modem and a CentOS based Linux router (SME 7, 2.6.9 kernel) with 5 NAT''d devices (3 PCs "DHCP", 2 Vonage adapters "static 10.10.2.10-11"). The quality problems are audio cutting out and popping. I tried the following (see below) based on a Cookbook example, but I still have
