similar to: cpufreq affects rate in, at least, htb

Hi all :) I''ve been using a tc setup for almost two years, but at some point (probably when I switched to kernel 2.6.x, but I''m not sure) it has started making something very weird. For a certain class, the rate is 125000bit and the ceil is 270000bit, but the fastest rate I get is about 75-80000bit, instead of the "promised" 125000, *with no other traffic in

Hi all :) If I set the burst/cburst parameter to, let''s say, 1500, the command "tc -s -d class show dev eth0" says that the value is 1499b/8 instead of the (correct?) 1500b/8. Is this right or am I doing anything wrong? Many thanks in advance :) Raúl Núñez de Arenas Coronado -- Linux Registered User 88736 | http://www.dervishd.net http://www.pleyades.net

Hi all :) I think that this issue has already been discussed on this list, but google didn''t find anything interesting, so I''m bringing the subject again. The output of "tc" uses "b" meaning "byte" and "bit" for "bit". The "official" suffixes for those units are "B" and "b", respectively,

Hi all :) I''m new to this list, as I''m new too to traffic shaping ;) I''ve set up an FTP server in my ADSL line and I wanted it to serve as fast as possible as long as I don''t use my outgoing ADSL bandwidth, and I''m currently using HTB for that (succesfully, I must add). The problem is (when the FTP server is serving higher than its

I visited yesican.chsoft.biz and the author proposes a way to match packets by less than some size . Here is the thing: match u16 0x0000 0xffb0 at 2 With this match he says that packet with less than 80 bytes will match the rule. Well, 0xffb0 translates to 1111 1111 1011 0000 (which is -80 BTW). So, if I am correct any packet with bits 4 and/or 5 set (together with any of the 4

I want to stop shaping from running on my box, without rebooting it. What''s the best way to get rid of any tc rules? I have tried "tc qdisc del dev eth0 root" which appeared to be successful but traffic through my box is still very slow.

I have found a few bugs in tc, and have produced patches for them. Two require changes to tc, one to the kernel. Where should I post these patches? -- Regards, Russell Stuart

Hi, all: I''m involved in the study about the QoS,but have some problems , hope someone could help me answer: 1. Why most traffic shaping implement in the egress side (Uplink) rather than the ingress side(Dnlink)?(e.g. why put the police rule on the smaller bandwidth side but not put on the larger side) 2. I can''t differ the functionalities exactly

Hi All How to classify packets belonging to a FTP session? Port 21 session is easy. but what about data transfers? Their port numbers (both) are above 1024. I was thinking about ip_conntrack_ftp. Something like: iptables -A FORWARD -p tcp --sport 1024: --dport 1024: \ -m state --state ESTABLISHED,RELATED -j CLASSIFY --set-class X:Y But what if I also have ip_conntrack_irc, for instance.

Hello all, I got this problem while trying to shape traffic with iptables MARK and HTB. MARK: targinfosize 8 != 4 --set-mark gives "invalid argument" error message. Kernel version is 2.4.29 (some patches from patch o matic applied) Iptables version 1.3.4 Intel x86 architecture. I saw this problem discussed in a few places, but the discussions didn''t come to a conclusion

Hi all :) Currently I''m shaping the traffic that goes to my ADSL router, using HTB. . Root (HTB) 1: . | . |------------------------| . LAN (1:1) ADSL router (1:2) . 90Mbit/90MBit 200000bit/200000bit . | . (Here go some children classes) I find the above a bit overkill, since LAN and

Hello ! Does anybody know how to build and use cpufreq support that should be in 3.2 since -unstable time ?

Hello, after spending several hours reading archives, I decided to write new post. I successfully set up packet classification, made some basic HTB setup, made some simple graphical representation from HTB statistics data... BUT, I cannot figure out how to refine HTB to get this behaviour: I need that class "p2p" should be the last one to get some link capacity. If I set both RATE

Could anyone summarize what the support status of cpu frequency changes is at present. I don''t seem to recall generic changes to the hpyervisor in that respect, but the linux tree has fairly extensive changes to the powernow-k8 driver (which would make sense to me only if all other cpufreq drivers are fully supported now, too). Thanks, Jan

Modify the cpufreq ondemand governor so that it can get idle and total ticks from the Xen hypervisor. Linux and Xen have different ideas of what an idle tick is, so the Xen values for both have to be returned in the same platform hypercall.

Dear all, The cpufreq modules have been distributed in Centos. But recently, I met a problem when I tried to test the power-related applications. The module can not be modprobed in kernel notwithstanding releated with Centos distribution.

Some versions of GCC are too stupid to figure out that cpufreq_dom is only used if !!domexist and always set in that case, and complain that it may be used uninitialised. (In general it is IMO better to avoid these kind of flag variables; I would prefer structures like for (...) { cpufreq_dom = dom; if (...) goto cpufreq_dom_found; } cpufreq_dom = 0; cpufreq_dom_found: but on
