similar to: tbf and prio blocking some flows entirely

Hi all, I''ve not been able to find an explanation of the relationship between prio and rate as they apply to the HTB technique. Hopefully someone on here will be able to help me. As I understand things, when prio values are assigned to an HTB setup, classes with a given prio value will only be serviced when there are no packets waiting in classes with a lower prio value. Now, does

Hi folks...!!! I need to generate qdisc statistics to show my 4 class (10, 20, 30, 40), i`ve all working with HTB and so on, but i need to graph this results e.gwith RRDTOOL. I found a script made in perl, that can to graph my 4 class, but i need to know which IP address on my LAN are using the bandwidth too, in other hand i need to classify the traffic by IP to show. This is an out of my

Hi all ! I''m building a network appliance whose goals are to enhance Voip quality on 512/128k DSL links. But, i have a voice quality problem, and i think i''m doing something wrong, but i can''t find what. Please excuse my terrible english, i''m french. >From what i''ve read, tc is the tool i need. I read the documentations, readmes and lartc.org

With the below script, whenever I ping 10.0.16.10 (which matches the only filter I have), traffic still get''s sent to the default 1:2 class instead of 1:1 and I don''t know why... Any hints? (kernel 2.6.12, iproute2-2.6.15) tc qdisc del dev eth0 root > /dev/null 2>&1 tc qdisc add dev eth0 handle 1: root htb default 2 tc class add dev eth0 classid 1:1 parent 1: htb rate

I have to match my packets based on MAC address, which I cannot do in the POSTROUTING chain, so I do it in PREROUTING using MARK. Then, I match on the MARK in the POSTROUTING chain to do a CLASSIFY. But this does not seem to work: wireless-r1 bwlimit # iptables -L -v -n -t mangle Chain PREROUTING (policy ACCEPT 3353K packets, 941M bytes) pkts bytes target prot opt in out source

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

I am trying to get IPP2P working on my router. Thus far I can see connections being marked (see below), but they don''t seem to get saved or something. When looking at /proc/net/ip_conntrack, nothing has anything other than 0 for mark. The iptables commands for this are: iptables -t mangle -A PREROUTING -j CONNMARK --restore-mark iptables -t mangle -A PREROUTING -m mark ! --mark 0 -j

Hello everybody, sorry for bothering you, but after some hours, I''m stuck. I''m living in a student''s foundation where I want to connect lots of people to a tiny DSL link. We have exactly four types of traffic. We want a really hard PRIO solution (as I promised to someone that group X will only use the link capacity which isn''t used by group Y). I could make a

Hello, I''m using Linux kernel 2.6.x and tc (from iproute2 package). I''m trying to use HTB or HFSC scheduler in order to limite the rate of outgoing packets and also in order to minimiez delay for RTP stream. But I didn''t suceed in having this 2 QoS services working. I use Iptables in order to classify packets. Here is my HFSC conf. In fact the pings that i send from

Hi, I''m using tc and HTB to shape my outgoing ADSL traffic. I was trying to make some graphs on the classes by meassuring the "sent bytes" of each class using rrdtool to store the data (as kbps after conversion). I expected that meassuring the root class I would get values similar that the ones I get measuring the interface counters but they differ by a large amount. Is

Hi I have tested with FC3 but iam not able get any good results on that. in the list some one recomend me that > 3.17 HTB should work I saw latest FC4 test2 has the HTB 3.17 with iptables 1.3.0 i have install in my P4 box, and trying to test when iam uploading its working perfect, but when iam downloading its going to default class can some one experinced the same problem below is the my

Hello, I have one Q. What is better when using as leaf in one leaf with several hosts (like subnet) to splice traffic equaly to user number? Like 2 users = 256/2, 3 = 256/3 and so on. WRR was pretty good for this job, but it''s only for 2.4.21 kernels and mine''s 2.4.22. So what is better: SFQ or TBF? -- Artūras Šlajus _______________________________________________

I run a small Linux webserver and NAT router from my cable modem at home. Whenever someone starts an http download, all other traffic from my LAN is starved. Bandwidth is not really an issue, but latency is particularly horrible -- pings that usually come back in 20ms can take up to 600ms while the web server is active! I set up QoS (netfilter+iproute2) on the NAT machine in an attempt to give

The docs[1][2] suggest it''s 1024, but tc says something else: # tc qdisc add dev eth0 root tbf rate 1kbps latency 50ms burst 1500 # tc -s qdisc ls dev eth0 qdisc tbf 8009: rate 8000bit burst 1499b lat 48.8ms ^^^^^^^ Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) rate 0bit 0pps backlog 0b 0p requeues 0 If 1k were 1024, then I would have 8192bit above.

Thanks for quick reply Andreas! > Every class is allowed to use bandwidth as long as it does not have to > borrow (the specified rate is guaranteed). Prio in HTB only affects > borrowing bandwidth from other classes... In the example below, the class > 1:5 should be allowed to borrow bandwidth before 1:14 does. Thats exactly what I want from HTB to do..to prio the borrowed bandwidth.

Hi, Having issues getting a replace command working correctly. The error reported is "RTNETLINK answers: Invalid argument" which isn''t descriptive or helpful. The command i''m running is: tc qdisc replace dev ppp0 parent 8001:D handle D: tbf rate 5Kbit burst 5kb latency 70ms The idea being to replace an sfq with handle D and hopefully limit a certain user in my

Hello... Im trying to setup HTB to allow me to shape traffic from two upstreams that meets on single lan0 interface. I prefer to use HTB qdisc within HTB root qdisc for cleaner rules design. Seems that it doesnt work at all. tc -s class show doesnt show any traffic on other classes attached to HTB qdisc. Linux 2.6.20.7 iproute-2.6.20-070313 Weird thing is that tc -s class show that 1: and 2:

Hi Everyone, This is a simple question but I don''t understand why the below tbf is not working as expected by throttling traffic to 5kbps If I throttle a PC''s traffic using the below when traffic exceeds 5kbps packets start getting dropped (as they should) but all traffic gets dropped. not just the bit over 5kbps. TC="tc add dev ppp0" $TC parent 8001:2 handle 2:

Hi all, Can you tell me where is the documentation for the new IFB (implemented in kernels > 2.6.16). Thanks in advance! Nikolay
