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

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

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 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.

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

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 :) 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''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? Thanks in advance :) Ra?l N??ez de Arenas Coronado -- Linux Registered

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.

Hello. I am wondering if the default (auto-computed) burst and cburst parameters are appropriate values for my application. I have a 100 mbit interface which is connected to a 16 mbit uplink. I am sharing this bandwidth into a set of partitions (tc classes) defined as follows: root class [1:1] |

All: Does anyone know what the burst and cburst parameter do? My understanding so far: * I see a lot of different definitions on the web. It seems like burst is the number of bytes sent before serving other queues/classes. So if burst was 1000 bytes and class rate was 100kibit per second. It would send 1000 bytes each time the scheduler service that queue to a rate of 100 kbit per

Hola a todos/as: Tengo la siguiente duda: Construyo una lista de tamaño 2, del siguiente modo: miLista<-list() miLista[[1]]<-list(nombre="Ana", apellido1="Pérez", apellido2="Sánchez") miLista[[2]]<-list(nombre="Carlos", apellido1="Núñez", apellido2="Sierra") Le aplico la función turnoLaboratorio: miResul<-lapply(miLista,

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.

Hi, I''ve been using htb fine to separate outgoing SMTP traffic from HTTP traffic so sending big emails doesn''t affect browsing. As long as ceil == burst and the sum of all rates don''t exceed the root class'' rate all is fine but when I incorporate ceil I would expect (from lartc howto) that when other classes are idle the remaining bandwith would be assigned

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. Here are the details : -ROOT 2000 kbits -HIGHPRIO SUBCLASS 50 kbits prio 0 -SUBCLASS1 750 kbits prio 1 -SERVICE1 250 kbits prio 1
