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

Ok, this is a rather large annoyance... How do you redirect the error output for TC? It does not seem to use any of the standard file descriptors (like STDOUT or STDERR) for error output. I have tried: tc <blah> 2>&1 1>/dev/null tc <blah> 3>&1 2>&1 1>/dev/null etc No matter what I do, I cannot seem to redirect the output. Anyone have any suggestions?

Hi, I am new to the Linux Advance Routing Project and to Policy Based Routing as implemented in Linux.... but I have been using Linux for 10 years so not _really_ a newbie.... Looking at the lartc.org website I came across the reference implementation of a traffic shaper... I also have Matt Marsh''s book on ''Policy Based Routing using Linux'' which covers traffic

Hi to all, i''m following this guide (http://www.opalsoft.net/qos/DS-28.htm), is very detailed, but i''m a bit confused about queuing disciplinse of leaf classes. In this guide the author uses PFIFO (see the scheme that i attached at message) in this way: # tc class add dev eth0 parent 1:21 handle 210: pfifo lmit 10 # tc class add dev eth0 parent 1:22 handle 220: pfifo lmit 10 #

I''m using HFSC to limit bandwidth for our wireless customers. However, I''d also like the bandwidth prioritized based on packet type. This is what I''m trying right now, and I''d just like some input from anyone out there knowledgeable in this on whether it does what I want it to do: Eth1 -> HFSC ........|-> HFSC (User1) (Min 512 Kb, Max 1024 Kb, Burst 1536

Sorry for making this a cross-post, but the pressure is on for getting this bandwidth shaper working. I have an interesting dilemma with bi-directional packet classification while doing ACK prioritization. This is an overly simplified summary of my setup: Internet | Eth0 | Router | Eth1 | Intranet A client on the Intranet establishes a flow to a server on the Internet. Packets get

My problem with HFSC tc command is ... tc command''s HFSC have a lot parameter with 4 curve type SC curve -> umax dmax rate LS curve -> umax dmax rate RT curve -> umax dmax rate UL curve -> umax dmax rate so i''dont know which parameter are appropriate for my test case such real time class which curve are appropriate and good working result. my assumption about

Hello, I’ve read this Article avout VOIP and HFSC http://automatthias.wordpress.com/2006/06/30/hfsc-and-voip/ I’ve got few questions ?

Hello, I just found the great howto and started shaping my internet connection. The howto''s last update is a liitle in the past now so I have some questions about how things are done the best way nowadays ;-) To ensure a stable and low latency voip communication I added an HFSC qdisc to device ppp0 (1 Mbit SDSL). There are two classes (by now): One for SIP and RTP and one for the

hi all, long time since i posted on the list. just wondering if anybody has played around with hfsc and if so could he/she share their info on it thanks adrian -- To mess up a Linux box, you need to work at it; to mess up your Windows box, you just need to work on it. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl

I have a lot question about tc-command because now i''m doing research to compare performance between HTB and  HFSC so i''m doubt a lot thing and your reply are so very helpful to me ... My question is In HTB tc command question 1. I''m use opensource (Mastershaper) for help to config traffic control but when i''m try to config HTB, I''m doubt about

Hi! Do you know somthing about hfsc and bps? There''s no output for speed only for packets. Doesn''t hfsc support such a field? tc -s class show dev eth0 class hfsc 1: root Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) rate 0bit 0pps backlog 0b 0p requeues 0 period 0 level 2 class hfsc 1:11 parent 1:1 sc m1 0bit d 18.0ms m2 1000Kbit ul m1 0bit d 0us m2

I stumbled upon a problem while upgrading Ubuntu 13.04, Shorewall version from 4.4.26.1 to 4.5.16.1. Everything was working fine before, after upgrading the script wouldn''t start. First some config files. tcdevices: #INTERFACE IN-BANDWIDTH OUT-BANDWIDTH OPTIONS REDIRECTED eth1 - 6300kbit hfsc,classify ifb0 - 6300kbit hfsc

1. HFSC have 4 curve such sc, rc, ls, ul and 1.1 In leaf class can specify rc for guarantee service (bandwidth and delay) and If want to sharing fairness exceess service, we must specify ls and ul curve too (ls curve with paramater m2 specify at lease sharing bandwidth in that class will receive and ul curve mean maximum bandwidth in that class will receive) so i''m doubt .. about if i

hi, I would like to use the HFSC scheduler for my QoS. I''ve 4 class and 2 of them need to control the bandwidth and the latencies so I think I must use HFSC. So I read some doc ( http://del.icio.us/tag/hfsc ) but its not very clear. I make some tests with differents parameters but I''m not able to use correctly this scheduler: $TC qdisc add dev $dev root handle 1: hfsc default 40
