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 :) I''ve tested this and having a cpufreq that slows down the CPU affects the rate of HTB. My ondemand cpufreq governor scales down the CPU frequency about 40% and this is more or less the slowdown the rate suffers, 40%. Any known way of dealing with this without having to disable cpufreq?

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 :) 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 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

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

Hi, We have a 256 kbits/s (kilobits per second) link to the internet. it is a router running Linux that belongs to our ISP. They have given us 8 internet ips. (i.e- subnet is 255.255.255.248). one has been given to this router. I have given another internet ip to the firewall running CentOS 4.5. iptables is running on it. And also, I have installed iproute2 pkg as well. pls see below for

Hi all :)) This matches what I want: tc filter add dev eth0 protocol ip parent 1:0 prio 9 u32\ match ip sport 0x3000 0xf000 flowid 1:22 and traffic goes to 1:22, but this one doesn''t match: tc filter add dev eth0 protocol ip parent 1:0 prio 9 u32\ match tcp src 0x3000 0xf000 flowid 1:22 I don''t understand why the first one matches and the

Hi all :)) Sorry for asking again, but got no answers and google doesn''t give useful information (seems like "nexthdr" doesn''t work right, but I don''t know why...). I really want to know what am I doing wrong... This filter matches what I want: tc filter add dev eth0 protocol ip parent 1:0 prio 9 u32\ match ip sport 0x3000 0xf000

Hello, I''m a total tc newbie, and I''m trying to tweak the wondershaper script (http://lartc.org/wondershaper/) to get a slightly different result. Excuse me if I will not use the correct technical terms, it''s a whole new world to me :) wondershaper.htb creates 3 HTB classes; 1:10 is high prio, 1:20 is bulk (default), and 1:30 is low priority. The classes are

Hi, Is there any tested good HTB script for traffic shaping available like as that of CBQ available at. http://freshmeat.net/projects/cbq.init I am n new bie and need to work on htb. -- Regards, M Arman _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Is there a way to apply wondershaper w/ htb to a port range? I have a ftp server on port 65432 and passive ports 50000-60000. Is there a way to set a range? or do they have to be individually listed? The following doesnt seem to work: # low priority source ports NOPRIOPORTSRC=65432, 50000:60000 # low priority destination ports NOPRIOPORTDST= Mark

Hi everybody, I have a network that only uses terminal services. Look at the diagram. 20 machines running WinXP <-> LinuxFW-1 <-> 1Mbit link dedicated fiber link <–> LinuxFW-2 <–> Terminal Server I’d like to give the maximum priority for bandwidth to terminal services (port 3389).
