Hello Sorry this got mailed twice, so please disregard every other mail i sent before this one :p i was wondering about two things concerning this software; 1. Does this work with a bridge?(i know you can use iptables on bridged traffic with a kernel patch, but i dont know if bwmd handles this..) 2. If i update settings in firewall.xml, and then add the new iptables rules by hand, will bwmd manage the new traffic flow without restartin= g the process? This is quite essencial, as i am working for a small isp and we cant down the uplink every time we need to manage another traff= ic flow.. Thanks for great work on this software! I could be interested in writing a web/cgi-frontend for this(to add new flows and such), if i get the time, or if my boss sees it as a necessity :) regards Bj=F8rn Magnus Mathisen |

Kobe, that I think is be best solution... me, being as I am like to take the most complex route.... 1. there is a iptables match called connbytes, if you match traffic with this say at 32k... you could roughly determine if the person is downloading something (or viewing a large webpage) 2. when you match the traffic, you can use CONNMARK to mark it & restore the mark 3. if this mark matches that used in bwmd it will limit that traffic havn't used connbytes yet as it looks like it affects connlimit or something, but in theory it works. -Nigel |

You are party right. The point of bwm_tool is that you first categorize your traffic any way IPtables let you do, so you can divide FTP from HTTP and put P2P traffic aside in it's own class, you can also categorize on source IP. This is handy if your clients have fixed Ip's (or ranges of IP's). After you made your categories you assign each ons of them: - a priority - a maximum bandwith usage - a burst bandwith rate After that the deamon tries to enforce this limits. Solving your specific problem can be accomplished rather simple. If you assign each and every IP you have in your subnet (10 as you state) a maximum rate of, let's say 750 kbit, wich is a nice and comfortable speed, and you limit your entire subnet to 900 kbit so your connection will never be 100% used. If you then prioritize (via QOS or bwm, or both) the tcp-ACK packets your problem will be solved, even without theze prioritizion you will noticy a significant performance improvement. If the per-IP thing is not an option (dynamic ip's, many travveling pc's, ...), just assign the 900 kbit to the whole subnet. The reason of the 'slowness' is that your router/uplink is that it's overloaded with data that even the TCP-ACK packets aren't getting true, and thus effective creating a bottleneck. With this setup the tcp-ACK packets have sufficent room to always pass quick via your uplink.

Hello, I have been trawling the internet for a linux based Bandwidth management system that we could implement into our community broadband network. I came across your software through soundforge via google, am I right in thinking the software dynamically manages traffic or does it limit traffic to individual users? Our problem is we have a 1MB satellite link shared between 10 people when everyone is surfing webpages it is fine but when someone starts a download the whole system becomes so slow! We basically want something that gives priority to webpage requests over downloading but when users are not web browsing it stops limiting the bandwidth. That's kind of it in a nutshell I would be ever grateful if you could reply back asap Thank You!

Dear Open Source developer I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate. You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it. With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development. With many thanks for your participation, Benno Luthiger PS: The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/. We have set up the mailing list fa...@we... for this study. Please see http://fasd.ethz.ch/qsf/mailinglist_en.html for registration to this mailing list. _______________________________________________________________________ Benno Luthiger Swiss Federal Institute of Technology Zurich 8092 Zurich Mail: benno.luthiger(at)id.ethz.ch _______________________________________________________________________ |

If you are wanting to use a BSD you may want to look at altq, which is well integrated into openbsd's pf. I use it extensively and it works well. It supports cbq, hfsc, priq, etc. I altq can be added to freebsd as a stand alone app but does not have the well written integrated controls with the packet filtering mechanisms as it does on openbsd. ------------ - Nick Buraglio, Network Engineer, NCSA - Phone: 217.244.6428 - GnuPG Key: 0x2E5B44F4 ------------ On May 19, 2004, at 12:35 AM, Nigel Kukard wrote: > On Tue, May 18, 2004 at 06:09:52PM +0200, Kobe Lenjou wrote: >> Hello, >> >> I don't think it's possible to use bwm on a BSD system.

Hello,
I don't think it's possible to use bwm on a BSD system. It's too
iptables/netfilter dependent I think.
Further, why would you even want to do so? BSD has it's own
limiting/shaping (dummynet) build into the kernel, wich is almost as feature
rich as bwm. (only the burst option is missing I think).

If it is used on the same box you are running applications as far as I know there is an iptables extension which allows you to match a specific users bandwidth.
