Hi guys Finally , after reading a lot of docs from larc/opalsoft/etc, I decided to start learning some QoS First of all I''m trying to shape only download from a iptables+squid+qos machine for 4 machines at LAN ( eth0) Can anyone help me , cause it is not working properly.. ----------------------------------------------------------------- #!/bin/bash # 128Kbps

Hi, I have typical situation, local LAN with private addresses, translated via NAT to internet. I need to shape ingress traffic (from internet to local LAN) in several HTB queues accorting to destination (private not public) IP. So I need mark packets to divide them to corresponding queue. According to http://www.docum.org/stef.coene/qos/kptd/ I thing I have only one way how to do it, because

Hi Guys After googling a little I couldn''t find the correct answer.. When I use : tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 match ip dst 192.168.0.11 flowid 1:30 , I can shape traffic to 1:30.( works like a charm) Now instead tc filter I would like to use CLASSIFY as below: iptables -t mangle -A POSTROUTING -o eth0 -d 192.168.0.5 -j CLASSIFY --set-class 1:30 but when I

Hi, I''m looking for info about IFB devices and how I can use it to incomming traffic shapping. Has IFB any web about it? Do any body known where I can find more info about it? I found this: http://linux-net.osdl.org/index.php/IFB But I can''t stand fine how to use it to allow many ifb''s devices or how to use it with "tc actions". Any help? Thanks --

Hi I am very unclear about the wonder shaper and a bit of a novice with Unix all together I have a question for you and I hope you can answer Basically my office is getting a couple of people slowing down the network so ive been looking around and found wondershaper What I want to know is that can I rather than having low priority ports have it with high priority ports And

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

Hello I''ve setuped a bridge with iptables + layer + ipp2p + tc I don''t know how to shape passive ftp ? If I put rules on port 20, 21 or using layer 7 iptables accounting still empty ... When I done a tcpdump I can see that othe port than 20 or 21 are used ... Any Ideas of how I can achieve this ? Regards

Hey folks, I stumbled across the Mastershaper project ( http://www.mastershaper.org/ ) but I have a little problem: I wanted to shape the traffic coming from the router itself aswell as coming from the LAN behind the router, for that task I need IMQ, but with IMQ iptables-(layer7)-matching is not possible. Now I''ve talked with the programmer and he said the following: >The problem is

Hello, I have eth0 - internet eth1..4 - local networks on eth0 i do $IPTABLES -A POSTROUTING -t nat -o eth0 -j MASQUERADE I want to balance out/in load for eth1..4 and localhost (mainly squid). Nat makes impossible to do it on eth0, so I installed IMQ. I need to get to on imq0 unnnated in/out traffic that I could make priorities for protocols and networks. Do somthing like this: prate=1Mbit

I''ve followed this list for quite a long time and have even posted a couple of times. I used the early versions of IMQ from Devik (I think that was his name), and it worked well. I only ever got the chance to implement it in my test environment. I now need to implement it in my production environment. My Linux core router has nine interfaces and has a 27 megabit connection to the

ive got such network: |--------| |-------------| | WORLD |---|ROUTER/server| ------ NATED LAN |--------| |-------------| I want to use imq on ROUTER, what behaviour to choose ? AA, BA, AB, BB ?? --

Hi, I''m trying to configure IMQ to work on the same machine with frottle (http://frottle.sourceforge.net). The problem is both feed themselves packets through netfilter queueing mechanism, but currently there can only be one netfilter queue per protocol family. To explain why I need IMQ in the first place I have to explain what frottle does. It is a deamon that tweaks the behaviour of a

Hello all, I´ve read http://lartc.org/howto/ and now i am just confused, i think my skills with linux are not very good, so asking for help. I have a linux box with two ethernets cards eth0(gateway 1mb) with is the host for some sites and emails and eth1(nat interface) with provide internet acess to other 5 pcs. I would like to limit the bandwith 512 k for the eth0 and 512 k for eth1 however

[I sent this earlier but I guess the list is subscriber-only?] I just set up wondershaper, it has a simple filter on the downstream direction to limit the bandwidth usage: tc qdisc add dev $DEV handle ffff: ingress tc filter add dev $DEV parent ffff: protocol ip prio 50 u32 match ip src \ 0.0.0.0/0 police rate ${DOWNLINK}kbit burst 10k drop flowid :1 This is effective but is there any way to

Hi Guys, Here is a question that is probably of concern to many of us. I am under pressure to provide some solution for ingress traffic shaping. What my customer demands is to divide the downstream (ingress) of an ADSL lines to two classes of traffic - important traffic and non important downloads. He has a very reasonable requirement: he wants a guarantee of at least 1000kbps at all times for

Hello all, I have been doing a lot of archive searching over the last week reading posts on IMQ and it''s apparent stability / instability. I have seen a number of posts about it not being maintained as well. Can anyone talk to me about IMQ''s stability in a heavy throughput environment (20 Mbps) and what was causing IMQ to fail if you know. Thanks, Mike

Hello, I am using the following iptables POSTROUTING rule to NAT some RFC 1918 addresses: iptables -t nat -A POSTROUTING -s 192.168.19.23 ! 192.168.0.0/255.255.0.0 -p tcp --dport 80 -j SNAT --to-source 10.32.4.2 (I am using SNAT instead of MASQUERADE for performance reasons). I have several addresses on the 192.168.0.0/16 subnet that I am SNAT''ing similarly. Problem is, ''tc

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 #

On a router, there is no need for and IMQ because there is always an egress path. For example: Internet -> eth1 -> iptables -> routing -> ... -> egress qdisc -> eth0 -> LAN LAN -> eth0 -> iptables -> routing -> .... -> egress qdisc -> eth1 -> Internet Local Process / Proxy -> routing -> iptables -> egress qdisc -> eth1/eth0 ->

Hi all, I have setup two multipath route tables on my system for doing failover routing, What I want it''s that if GW at route1 of the MP is dead, traffic goes by route2, for doing that I have created the multipath routes as follows: ip route add table mail.traffic proto static nexthop via ${GW1} dev eth1 weight 1 nexthop via ${GW2} dev eth1 weight 250 But it does not run as I
