I''ve set up Traffic Shaping on a Linux Router. Using HTB with SFQ, i''m trying to slow down heavy downloading for 20 subscribers over a 2048 kbit downlink. I''m classifying internet related traffic using iptables marking. bri0 is my local lan bridge, receiving egress traffic destined for subscribers. tc qdisc add dev bri0 root handle 1: htb default 2 tc class add dev

Hello, I wrote a simple traffic shaping script (below) that should have allowed me to shape my internet traffic a bit (ppp0 - adsl 128kbit/64kbit; local interface eth0). The script works only partially - the speed is being limited but too much. Without running this script my download rate is about 10kBytes (with second computer also downloading at about 6kBytes). After running it my download speed

Hi, I have a typical configuration for my firewall/gateway box: single network card, with a pppoe connection to the DSL modem. I''m already successfully shaping the uplink (how come that the wondershaper.htb doesn''t use the ceil parameter? It should implement bandwidth borrowing!) but i found the ingress policy a little bit rough. I''d like to keep the traffic categories

I am looking for a good htb traffic shaping script to prioritize incoming traffic over outgoing traffic for my machine. I have a 100mbit line, ftp up, backup data comming in, but whenever mirrors starts grabbing it they use all the traffic and the backup data comming in (the important data) drops to like 300kb/sec. I was thinking some script doing sleep 60 [if downstream > 1mb/sec, limit

Hi, complete newb and I apologise for it. I have a setup where my linux box has multiple broadband connection where I am routing certain things over certain interfaces, currently 2 links eth2 is a 1500/256 and eth3 is a 512/512, eth0 is the link to the LAN for users. What I am trying to do is traffic shape the information going out eth0 to the local users by the interface the traffic arrived

Hi, I''m trying to perform some (what I consider) basic traffic shaping on our network utilising HTB. I have mostly reused the example on the lartc.org site: tc qdisc add dev eth0 root handle 1: htb default 10 tc class add dev eth0 parent 1: classid 1:1 htb rate 100mbit burst 24k tc class add dev eth0 parent 1:1 classid 1:10 htb rate 50mbit ceil 80mbit burst 19k tc class add dev eth0

I''m trying to shape traffic on a Devil-Linux box. This note was originally sent to their maillist, because the LARTC list appears to have been down for the past few days. My mailbox was just flooded with a half dozen or so confirmation requests in response to my repeated attempts to subscribe to this list. ---------- Forwarded message ---------- From: drew einhorn

Hello. I have a 1024/256kbit ADSL and tried to shape outgoing traffic in order to improve latency. Here is my config. UPLOAD_RATE="256" UPRATE="$[4*$UPLOAD_RATE/5]" (a little smaller) UP70="$[7*$UPRATE/10]kbit" UP30="$[3*$UPRATE/10]kbit" UP20="$[2*$UPRATE/10]kbit" UPRATE="${UPRATE}kbit" IF="eth2" IPTABLES="iptables -t

Hello, I''m trying to get lossless VoIP traffic over my 3000k/500k ADSL line. Shaping outgoing traffic is no problem: I set total ceil for outgiong device (ppp0) to 450kbit and put VoIP into highest prio class. Even during full upload the voice is clean on the other end. Now I tried to get the same result for incoming data. I attached HTB to eth1 where the incoming voip traffic is

Hello! My system is: Internet ADSL(PPPoE) ---> ppp0 [LINUX server(router)] eth0 ---> LAN Server(router) is running on LINUX Slackware 8.1. I have recompiled a 2.4.22 kernel, enabled all QoS support in the kernel config, including HTB. My ADSL bandwidth is 256Kbit/s for download and 64Kbit/s for upload. I use the following HTB+IPTABLES configuration, because I want to reduce bandwith for

Hello all, I am providing broadband service through DVB circuit. I have 4KB uplink and 32KB downlink. I want to share 32KB downlink bandwidth among 192.168.0.0/24 (20 users in this subnet i.e 192.168.0.2-192.168.0.22)subnet where each user will get 2KB to 6KB bandwidth. And from 4KB uplink bandwidth each users will get only 1KB to 2KB bandwidth.

Hi All, I''ve got an interoffice IPSEC VPN in place that I''m trying to give priority to terminal service (tcp 3389) traffic. I''ve created rules at each end, but have hit a bit of a dillemma. As the data is encrypted I must also give highest priority to protocol 50 otherwise the priority is lost as the packet gets encrypted. When I do this however, I can''t

Hello. I have a linux server connected to a gigabit lan, and though that lan to a 768kbps/768kbps DSL modem. I''m trying to shape my webserver running on port 80/443 down to 512kbps, while leaving all other ports alone. The current configuration script that I''m using is as follows: tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb default 99 tc class add dev

Hi, It has been quite a while since I looked at what was happening in Linux traffic shaping, so I am not sure if this has been discussed / improved on since I last looked. We use a traffic shaper based on HTB. The basic principals work fine, but we have a problem with ''intermittent trafic'' like http and interactive ssh sessions. Each of these categories of traffic have

Hi - I''ve been going through the LARTC how-to and have successfully used the sample scripts (and wondershaper) with my xDSL links. I''m now faced with the challenge of providing 8 users at work an effective remote access connection over a PSTN ppp connection. The critical traffic in this case relates to our stock enquiry application which is running over terminal services.

Lartc readers I have a peculiar problem with shaping and firewalling. My tc rules work great, below is a smaller version: #Root tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb default 100 #Root Class tc class add dev eth0 parent 1: classid 1:1 htb rate 1024kbit quantum 20000 burst 15k #Class for each user tc class add dev eth0 parent 1:1 classid 1:2 htb rate 32kbit ceil

Hello At first I must tell you that I´m a real newbie with Linux (and english as well...) I´m using 2 vlans and shaping works quite well without vlan Now I want to do load balancing at these vlans. Any vlan should get the same minimum/maximum bandwidth of download and use the bandwidth that isn´t used by the other one at the moment. But with vlan the shaping doesn´t work. Can you please tell me

Hi, I would like to prioritize VOIP traffic when we use the phone, but other times not do traffic shaping at all. Right now I have my openwrt router set up with htb to do shaping. In order to get it to work well I had to set my upload and download speeds much lower than my line speed. With these settings, I get good VOIP reception even while surfing the net and doing a long download. However,

Hello, Could somebody explain following issue ? I set up htb class on outgoing external interface to shape p2p upload traffic. I limited it to 4Mbit/s. I also set up iptables counters chains in FORWARD chain to calculate traffic generated by p2p and others. While tc stats show that p2p shaping class keep defined 4Mbit traffic, iptables counters show me that p2p traffic exceed traffic to 150%

My needs is limiting the outbound traffic of an smtp mail server. It is connected to a gateway via 100Mbit ethernet. I want limits its outbound traffic to max 3 Mbit. I have read lot of docs and tried various script without great results. Any simplest solutions? TIA. Regards, B.
