Hi, I´m shaping traffic using htb on both interfaces, I noticed that shaping download traffic is workinggreat but shaping upload traffic is not working at all (no sent packets, no dropped, no overlimits)I have eth0 facing the backbone and eth1 facing the LAN. Thanks for your help.These are the commands I run:tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1 htb default 10 r2q 5 tc

Hello! I have an internet connection of 64kbps garanteed in a channel of 256kbps. On this connection the metropolitan speed is 10Mbps and in the provider''s network the speed is 100Mbps. I have a few clients behind my linux box and i want to set up some limitations because some of them are using it irrational. I am marking the packets with 0 for internet; 1 for metropolitan 2 for

...evaluating collinearity. "Colldiag" calculates condition indexes and variance decomposition proportions to detect and track down collinear sets of variables. "Perturb" takes a different approach. It re-estimates the model a specified number of times, adding random noise ("perturbations") to selected variables at each iteration. Categorical variables are randomly reclassified. A summary then displays the impact of these perturbations on the stability of the coefficients.

Hi all. I have a bridge running Linux 2.4.24 that I use as a bandwidth manager on a broadband wireless network. I''m using HTB and SFQ to prioritize that share bandwidth on a per-cell basis. My IP tables rules divide the traffic based on IPand traffic type (using layer-7 filter and ipp2p). My goal is to make sure that p2p traffic on the network doesn''t sink all of the

I have a linear model y~x1+x2 of some data where the coefficient for x1 is higher than I would have expected from theory (0.7 vs 0.88) I wondered whether this would be an artifact due to x1 and x2 being correlated despite that the variance inflation factor is not too high (1.065): I used perturbation analysis to evaluate collinearity library(perturb) P<-perturb(A,pvars=c("x1","x2"),prange=c(1,1)) > summary(P) Perturb variables: x1 normal(0,1) x2 normal(0,1) Impact of perturbations on coefficients: mean s.d. min max (Intercept) -2...

Hi all I have a trouble configuring the qdiscs, when I indicate the "perturb 10" option to tc, i gives me this error: tc qdisc add dev eth0 parent 5:1323 handle 1323 sfq perturb 10 RTNETLINK answers: Invalid argument if I don''t put the "perturb 10" option, it works. another question is about iptables, when I indicate the " --set-mark" option: iptables -t

Dear All, I''m using the kernel 2.6.6, iproute2-2.4.7.20020116, iptables v1.2.9, and gentoo. I have a leased-line 64 kbps. I can see the counter works in iptables, but in the htb, it doesn''t go to the right class (it always go to the default class). Any help will be appreciated here''s my htb conf #!/bin/bash tc qdisc del dev eth1 root tc qdisc add dev eth1 root

Hi, I''m trying to modify the Wondershaper script so achieve the following. 1. Prioritize traffic to the few IP addresses. 2. Everyone else should get a fair amount of bandwidth The problem I am facing is when I run this script is that the bandwidth seems to get halved. I tried to apply this script to a site where the upstream and downstream were fully saturated. I immediately saw

Hi! I''m using 2.4.17 + htb2_2.4.16.diff now. But I found the tc class show command won''t show the correct infomation like before... I got something like: # tc -s -d class show dev eth0 class htb 1: parent 1: class htb 1: parent 1: class htb 1: parent 1: class htb 1: parent 1: class htb 1: parent 1: class htb 1: parent 1: class htb 1: parent 1: # tc -s qdisc

With the below script, whenever I ping 10.0.16.10 (which matches the only filter I have), traffic still get''s sent to the default 1:2 class instead of 1:1 and I don''t know why... Any hints?

Hello to all people there . Can i guarantee ICMP respond time no metter how loaded is internet line . i have typical NATed enviroiment like External IP |linux router| LAN - 192.168.0.0/24 i have example setup with IMQ but is it possible to be done also if i attache htb to eth0 and eth1 for example . if i start shaper ping i better that without shaper but it''s not guarantted i mean

Hello, I have problems with htb. The problem is that when I download any file via shaper with htb, the traffic is very dinamic, it jumps, for example: if i have set ceil = 128kbit the results that it jumps from 112kbps to 144kbps or smth like that maybe its not very bad, but when the traffic drops down to 40kbps or less and then after 1 or 2 seconds jumps to 144kbps, its bad :-( and it is often.

hello, I have working htb system with about 1000 users. Until now I reload all rules at change, but it take too much time to apply. I cannot delete applyed filters. There is rules for one user: #!/bin/bash -v # Download shaper EX -> 2:20 /sbin/tc class add dev eth2 parent 2:20 classid 2:1775 htb rate 8000Kbit ceil 10000Kbit quantum 1514 /sbin/tc qdisc add dev eth2 parent 2:1775 sfq perturb

Actually i gave up, i tried and tried and tried so many times, upgrading software falling back to an old version but it didn''t work, that''s it. i can''t do work together tc with iptables and iproute2 when i mark a packet with iptables tc doesn''t recognize them so it falls at the default leaf of the tc''s tree what i like is to mark packets depending on

tc qdisc add dev eth0 root sfq perturb 10 I want to set perturb to 8 then i used this tc qdisc add dev eth0 root sfq perturb 8 system give me the following message RTNETLINK file exists I delete the rule by this :"tc qdisc del dev eth0 root sfq perturb 10" please tell me how can i delete the rule by another way and where is "RTNETLINK file"

Hi I''m doing traffic shaping with tc on ''10.0.0.0/30'' and ''10.0.0.28/30''. I want to delete part of shaping rules on the fly. (see my configuration at the end of this mail) I wan''t to delete the shaping for ''10.0.0.0/30'' on the fly while still keeping the shaping for part ''10.0.0.28/30'' running. When I for

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
