Hi there, i am trying to shape a network for a college dorms... INTERNET---- ETH0--------Nat Box-------ETH1--------LAN I have set up classes of traffic (HTTP, FTP, MAIL, IM, OTHER) and i have assigned a rate for everyone with a HTB qdisc. The limit based in traffic is working flawlessly. However, under every HTB class i have set up a ESFQ queue discipline with hash value set to

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

Hello Mongrels, Mongrel 1.1 is out with fullblown JRuby support, some reorganization, and some bugfixes. Also, Mongrel_cluster has been updated to 1.0.4. Go subscribe to the all-new news feed, because we probably won''t announce to the list anymore: http://mongrel.rubyforge.org/rss.xml Thanks Evan, and the Mongrel Team -- Evan Weaver Cloudburst, LLC

Hi! I have read all informations i could find, but some things are still not clear. My setup is: ---INTERNET1(eth0)-\ /- Local net1 (eth2) GW ---INTERNET2(eth1)-/ \- Local net2 (eth3) I have NAT and a working setup using HTB,SFQ, classifying with the iptables -j CLASSIFY way. I shape only the traffic coming from the internet heading to the intranet. I would like

Hi, I understand for 1 d classifiers, you can use ROCR package. Is there a package you can plot ROC curve for 2d classifiers? One of my colleagues asked me about this. I have been quite puzzled, conceptually, how you can do the ROC curve for 2d classifiers. Can someone share his/her knowledge or experience? Thanks in advance. --...

Hello, I''m using Linux kernel 2.6.x and tc (from iproute2 package). I''m trying to use HTB or HFSC scheduler in order to limite the rate of outgoing packets and also in order to minimiez delay for RTP stream. But I didn''t suceed in having this 2 QoS services working. I use Iptables in order to classify packets. Here is my HFSC conf. In fact the pings that i send from

Hi, I am using some classifiers in RWeka packages and met a couple problems. (1) J48 implements C45 classifier, the C45 should be able to handle missing values in both training set and test set. But I found the J48 classifier can not be evaluated on test set with missing values--it just ignore them. (2) The ensemble cl...

Bests, Yongle Lai Hi, I am a newbie working on tc tool, i want to know whether we have the following classifiers available (1) source MAC address. (2) destination MAC address. (3) IEEE 802.1D user priority. (4) Ethertype (IEEE 802.3, 1998 Length/Type Field). Can any one help me in finding the help for the above classifiers. Thanks in advance Krishna Chaitanya

Hi, i''m newbie with traffic control. I create a script based in one from Jason Boxman (thx a lot). the upload flow is prioritized well, but when i download from a site, the down flow vary a lot from 25 KB to 4 KB. Before i use this script the downloads are constant between 22 an 25 KB. Perhaps there''s something wrong in my script ? I paste it, thx.

Hi, I have implemented qos at my gateway, mostly for speeding up dns and [video,voice] chat traffic and to slow down p2p traffic. It seems every thing is working properly, as by browsing speed has been improved. But I want to test it by sending various traffic and to see through which qdisc the traffic flows, so that i can be certain that it is working the way I want it to work. The rules

Could someone comment on the benefits of using CLASSIFY vs fwmark (or vice versa) in iptables? I''m getting ready to implement some basic tc for VoIP and most of the examples seem to use the (older?) fwmark syntax. Should I convert these to CLASSIFY? Can the two syntaxes be mixed? Also with U32? TIA, Edwin -- <=+=+=+==+=+=+==+=+=+=+=+=+=+=+=> Edwin Whitelaw, P.E. New River

Hello list I have a problem with classifying traffic from two providers, and about 600 users. I have the following situation: P1-\ | linux | --eth0-| box |-eth1 P2-/ | | P1 and P2 are coming from VLANs. I have 4 type traffic which I want to classify. The traffic is divided as follows: P1 - 100mbit from realm 0x70000 10mbit from realm ! 0x70000

Hi all, based on the information in the "Linux Advanced Routing & Traffic Control HOWTO", I was trying to set up traffic shaping on my firewall. While I found the HOWTO very useful, in the process I ran into some problems that I did not forsee: According to the HOWTO it seems that it should have worked, even after spending some time going through the sections looking for answers,

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.
