Does anyone have any pointers on how other people have implemented tcp window adjustment to do bandwidth shaping? Granted the basic idea is to set the window size to be RTT * bandwidth, but a quick squiz at google turns up mostly papers on how to implement this at the sender end with a view to some new magic TCP implementation. I''m really interested in notes on how to implement at

Hey list I have almost gotten my shaping setup up and running as planned. The last barrier seems to be tcp overshooting availible bandwidth when its starting a transfer, and thereby bursting the line, so ping rises for a moment. At least this is my best guess at the problem :) There is a possibility that its just plain old traffic being bursty for some reason.. I am using bittorrent to test this,

Hi, I am trying to do the simplest configuration of traffic shaping. So I did: shorewall.conf TC_ENABLED=Simple tcinterfaces eth0.2 External 500kbit tcdevices eth0.2 500kbit 200kbit And I am testing the speed on that interface - whether I did it ok or not, and my speed is still 4mbit/512kbit. So the question is - How to reduce the speed on interface connected

Hi all, I am very new to this group and also the Unix platform. I am having some questions related to Throtling. I have visited lot of sites but not satisfied except www.docum.org I am from India. Working on *nix platform & love to work on RedHat Linux. Thanks in Adv. to Group BY __________________________________ Do you Yahoo!? SBC Yahoo! - Internet access at a great low price.

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

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

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 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.

Hello, I have a problem with simple traffic shapping in shorewall, my current configuration is: zones vlan10 ipv4 # interfaces vlan10 vlan10 detect tcpflags,routeback shorewall.conf TC_ENABLED=Simple tcinterfaces vlan10 Internal 1mbit:50kb shorewall show tc Device vlan10: qdisc prio 5: root refcnt 2 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1

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

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

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

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

Hello, I want to select best Traffic Shaping algorithm that meet very good performance. What algorithm is best?

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

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

Will the following rules work to mark and shape OUTBOUND ftp speed (passive ftp ports 50000-60000) on my linux server? I want to be able to run these commands on the actual computer that is running the ftp server. iptables -t mangle -N MYSHAPER-OUT iptables -t mangle -I POSTROUTING -o eth0 -j MYSHAPER-OUT iptables -t mangle -A MYSHAPER-OUT -p tcp --dport 50000:60000 -j MARK --set-mark 1 tc

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, 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. 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
