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.

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 to have a configuration like this: ---INTERNET1(eth0)-\ /- Local net1 (eth2) GW--imq0 ---INTERNET2(eth1)-/ \- Local net2 (eth3) I...

Hello, I have some trouble in achieving the desired parametrisation for the weka classifier functions, using the package RWeka. The problem is, that the functions result=classifier(formula, data, subset, na.action, control = Weka_control(mycontrol)) do not seem to be manipulated by the mycontrol- arguments Perhaps this should be resepected via the handlers- argument , but the

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. -- Waverley @ Palo Alto

...ing 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 this box should be the most highly priorised packet, but there are delayed when i add load on the link (with a scp upload). What is strange is that the delay of thoses ping is not constant: Does someone have an idea about this issu...

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 classifiers in RWeka such as bagging and boosting: there is a

Hi Krishna, 1) If you want to classify according to MAC address, you could use iptables to mark the packet (using MARK target), but just source MAC is available for now. 2) Usually tc just could classify by fields of IP layer and its sublayer, so I think classify by ethertype is unavailable. 3) VLAN tag belongs to MAC layer! I'&...

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 -- <=+=+=+==+=+=+==+=+=+=...

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 - 100mb...

...S splitting only 30:1 (BAND 1) 30:2 (BAND 2) 30:3 (BAND 3) 1:4 -> PFIFO, handle 40: "starvation bitbucket" gets what is left, can starve at times The setup was apparently successful, tc does not complain and displays the structure: without any CLASSIFY targets, all traffic goes to 1:3 and is split in the three bands properly. Looks good. I can also add CLASSIFY for 1:1 and 1:4, which seem to fall into the SFQ/PFIFO buckets underneath, both look good. The problem starts with the HTB embedded in 1:2 as 20: -- I can never CLASSIFY traffic for it p...

...k that was set to put it in that classification. A response then comes back from the server and the router restores the mark it previously saved. Now it is flagged for Priority Band 1. The packet now traverses the iptables ruleset and remains classified as Priority Band 1 because the rules that classify it in a different manner don''t trigger. The reason these rules don''t trigger is that the original marking in the outbound direction is done on SOURCE MAC address. Since I can''t classify on SOURCE MAC address for packets coming back from the Internet, I am left with using...
