similar to: tc segmentation faults when trying to add pfifo_fast as leaf discipline on a HTB class

Thank you Andy! I did''t find why I could''t use the fw match in ingress. Now it works. Now I ran into another problem: When I try to add a pfifo_fast leaf qdisc dor htb classes it seg.-faults. Is pfifo_fast a special qdisc? I can succesfully add other type of qdiscs. I found that a similar problem was reported in february on a MIPS architecture. root@zefir:/usr/src# tc qdisc

Hi! I was updated kernel from 2.4.22 to 2.4.23 and now tc tools can''t correctly determine default (pfifo_fast) qdisc on interface: # tc/tc qdisc ls dev ppp0 qdisc pfifo_fast 0: [Unknown qdisc, optlen=20] but, if I assign f.e. cbq qdisc for some device all show correctly: # tc/tc qdisc ls dev ppp1 qdisc tbf 8009: rate 32Kbit burst 10Kb lat 1.5s qdisc cbq 66: rate 10Mbit

Hi all, I previously mailed this list explaining that I been given the task of implementing a dynamic traffic shaping scheme on an existing network. I was looking for guidance on how I should approach this but unfortunately I was unable to provide much information about the existing traffic shaping system. I have recently obtained the existing tc scripts though and was hoping someone could help

Hi , I have the problem with HTB queuing discipline.I am giving my setup below. 172.30.179.206 172.30.180.55 LAN | | WAN -----------------| LINUX WITH |-------------- 172.30.179.140 | HTB | 172.30.180.72 FTP SERVER FTP CLIENT On the LAN side i

hello folks, this is my first post to that list. so I hope I am not completely OT here :-) reading the (excellent!) lartc and then writing my own qos-script I have still some open questions which I will try to formulate now: - "Now we can optionally attach queuing disciplines to the leaf classes. If none is specified the default is pfifo." - I can''t find info about Pfifo.

Hi, I have a server and ten clients in a Gigabit network. The server has 125mbps network bandwidth. I want that the server has 40Mbps bandwidth reserved for client 1 (IP 192.168.5.141), and the rest bandwidth is for all other clients. My script looks like this (I use IFB for incoming traffic): #!/bin/bash export TC="/sbin/tc" $TC qdisc add dev ifb0 root handle 1: htb default 30

Hello, I use HTB on IMQ, and I would like to use pfifo_fast on my HTB leafs. Do I need to add a pfifo_fast qdisc to my HTB class, or this is the default one? I tryed to add and I got: RTNETLINK answers: Invalid argument It looks like pfifo_fast qdisc is not supported on HTB leaf... Any comments?

Hi, I have following queries: - 1.How to see data exchanged at all the bands of pfifo_fast(command)? "tc -s qdisc ls dev eth0" only shows following output qdisc pfifo_fast 0: bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 Sent 71132584 bytes 312294 pkts (dropped 0, overlimits 0 requeues 0) Its only showing data exchanged in band 0. 2.I am using following command to drop

I have a machine running 2.4.25 w/ wrr, ebtables-brnf, iptables CLASSIFY and esfq patches (not using esfq, though). I have wrr set up, and within each class I want to prioritize ssh, web, etc..., but right now I am testing with pings. I have the following in my POSTROUTING mangle table: CLASSIFY icmp -- anywhere anywhere CLASSIFY set 0:6 I find that if I attach a prio

I would like to use HTB''s prio parameter as the sole priority value for pfifo_fast. Is the TOS field in packets honored by an HTB class with the default pfifo_fast qdisc enqueued when coming from a child class with a prio parameter?! If yes, what''s the least expensive way (in terms of CPU cycles) of stripping all packets from the TOS field?!

Hello, I read about the pfifo_fast has 3 bands, which allow you to prioritize traffic into these bands. I cannot find anything about these bands in the tc command reference (http://linux.bergqvist.se/tc/). I might be looking the wrong place - in which case, where should I look for help with this qdisc? The idea is to give "time-critical" sessions such as ssh, telnet etc. HIGHEST

The HOWTO mentions 3 seperate bands for the simple pfifo_fast queue, how do I need to specify which band each packet needs to be in? Do I only need to set the correct TOS field or is there anything else I should do? Thanks. Tung

Hi, I have a cable modem with a bandwidth capped upload rate. I''d like to prioritize packets going outbound according to the TOS header of the IP field. I''ve read through the LARTC Howto several times, and I think I have a good feel for the information it it. It also seems that what I''m trying to do is pretty straight-forward and common. Unfortunately, the HOWTO

Hi list, I have a quick question about the priority mapping of tos bits. The manpage of tc-prio shows a nice table with tos bits and the band they are mapped to: TOS Bits Means Linux Priority Band ------------------------------------------------------------ 0x0 0 Normal Service 0 Best Effort 1 0x2 1 Minimize Monetary Cost 1 Filler

Hep Trying to get pfifo to work. Setup : |------|<--->eth1 (192.168.10.0/24) eth0---| GW |<--->eth2 (192.168.11.0/24) |------|<--->eth3 (192.168.12.0/24) read all documentation : http://lartc.org/howto/lartc.cookbook.interactive-prio.html here is my TOS mangling rulse in iptables : $IPTABLES -A PREROUTING -i eth1 -t mangle -s 192.168.10.0/24 -p tcp --dport

Is there a way of pulling individual leaf nodes out of the tc -s class show dev <thx> command? Say, similar to: tc -s class show dev eth0 parent 1:1 except for an individual leaf: tc -s class show dev eth0 leaf 1:12 Or, better year, is there a way to log or store statistics, so that you can pull up such things as max rate, max pps, max backlog, etc. - not just the

Friends I need to get R reading from a fifo. I want it to block till there is some data in the fifo, consume what input it gets there, do some thing with it then loop back and block again. Very simple. Yes? No. The example in the documentation works OK.. zz <- fifo("foo-fifo", "w+") writeLines("abc", zz) print(readLines(zz))

(using htb) I''m trying to learn tc filter and it seems the flowid parameter can only point to leaf classes. Actually, it can point anywhere, but it doesn''t seem to work unless it points to a leaf class. Is this correct? For example, I have this tree: eth0 | +------1:-------+ | | +------1:10 1:20 | |

Hi I am current trying to set up a guaranteed minimum rate for the leaf (1:1x). Also would I be correct in saying that the quantum is the dividing rule (so if I keep it the same "1532" and keep all the leafs in "1:1x" prio 3 they should all get the same amount of bandwidth shared across them equally?). For example below would the "rate" in the "1:1x" leaf
