Greetings -- in the "Linux Advanced Routing & Traffic Control HOWTO" chapter 14.1 on bfifo/pfifo it says that: "you can use this qdisc to determine the backlog on your interface". But it does not say exactly how. Command [#tc -s qdisc ls] outputs the number of packets sent so far but it does not output any info about the backlog. My first question is whether a command

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

Thanks for quick reply Andreas! > Every class is allowed to use bandwidth as long as it does not have to > borrow (the specified rate is guaranteed). Prio in HTB only affects > borrowing bandwidth from other classes... In the example below, the class > 1:5 should be allowed to borrow bandwidth before 1:14 does. Thats exactly what I want from HTB to do..to prio the borrowed bandwidth.

I don''t understand the following: root@jmnrouter:~# tc -s class ls dev vlan1 && tc -s qdisc ls dev vlan1 class hfsc 1: root Sent 0 bytes 0 pkts (dropped 0, overlimits 0) period 0 level 2 class hfsc 1:1 parent 1: sc m1 0bit d 0us m2 220000bit ul m1 0bit d 0us m2 220000bit Sent 0 bytes 0 pkts (dropped 0, overlimits 0) period 31304 work 7533852 bytes level 1 class hfsc 1:10

Hi folks...!!! I need to generate qdisc statistics to show my 4 class (10, 20, 30, 40), i`ve all working with HTB and so on, but i need to graph this results e.gwith RRDTOOL. I found a script made in perl, that can to graph my 4 class, but i need to know which IP address on my LAN are using the bandwidth too, in other hand i need to classify the traffic by IP to show. This is an out of my

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? (kernel 2.6.12, iproute2-2.6.15) tc qdisc del dev eth0 root > /dev/null 2>&1 tc qdisc add dev eth0 handle 1: root htb default 2 tc class add dev eth0 classid 1:1 parent 1: htb rate

Hi! Do you know somthing about hfsc and bps? There''s no output for speed only for packets. Doesn''t hfsc support such a field? tc -s class show dev eth0 class hfsc 1: root Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) rate 0bit 0pps backlog 0b 0p requeues 0 period 0 level 2 class hfsc 1:11 parent 1:1 sc m1 0bit d 18.0ms m2 1000Kbit ul m1 0bit d 0us m2

Hello... Im trying to setup HTB to allow me to shape traffic from two upstreams that meets on single lan0 interface. I prefer to use HTB qdisc within HTB root qdisc for cleaner rules design. Seems that it doesnt work at all. tc -s class show doesnt show any traffic on other classes attached to HTB qdisc. Linux 2.6.20.7 iproute-2.6.20-070313 Weird thing is that tc -s class show that 1: and 2:

What techniques and tools do you use to manage your feature backlogs? It could be as low tech as a post-it note, TODO file in your Rails project tree, or as high tech as a web-based collaborative tool. Thanks, Mark

Dear Community, sorry for the somewhat dumb question. Maybe someone has any pointer to how to setup the RED queue to mark pakets with ECN. In particular what are appropriate parameter settings for limit, min, max, etc. All my trials end up with either "RTNETLINK answers: Invalid argument", although the command line (at least for me) looks fine in regard to what is said on the

i am trying to do some traffic classification using the PRIO qdisc and i am having a few problems. I have a root htb class: tc qdisc add dev imq0 root handle 1: htb default 255 r2q 1 tc class add dev imq0 parent 1: classid 1:1 htb rate 768kbit and a child PRIO tc class add dev imq0 parent 1:1 classid 1:99 htb rate 96kbit ceil 600kbit prio 0 tc qdisc add dev imq0 parent 1:99 prio tc filter

Today I''ve noticed a bit strange (?) behaviour when prio qdisc is used. Example (having no filters/qdisc/etc. at the start) : Add simple 9 bands qdisc, set each mapping to lowest priority band: tc qdisc add dev $eth root handle 1: prio bands 9 priomap 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 8 If I do just that, all is fine - whole traffic ends in 9th band, what can easily be verified by tc -s

Hi all, First, let me say I''ve been most impressed with how quickly and professionally people on this list ask and answer questions. Next, let me say that with which I need help is properly configuring strict PQ, and gathering certain stats. Specifically: - I need to create a priority queue with four queues (let''s say they are of high, medium, normal, and low priority) - I

Hello All, We have a Linux cluster application that uses openssh as its inter-node communication mechanism and we've recently run into a problem that points to a potential scalability issue in openssh code. Our client nodes systematically open ssh connections to the server node to execute an administrative command. When establishing socket connections, the server side sometimes fails to

Hi all, Can you tell me where is the documentation for the new IFB (implemented in kernels > 2.6.16). Thanks in advance! Nikolay

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi folks.

Eric, I''ve attached the output from the command you requested below. I''m using kernel 2.6.17.12 and tc version ss060323. I''m have a nforce4 onboard giggabit controller using the forcedeth driver, if that makes a difference. Charlie, I''ll take a look at the Apache model for throttling, thanks. I was going for tc because was going to try to add additional

Hello, I submitted a patch <http://dev.rubyonrails.org/ticket/3287> ( http://dev.rubyonrails.org/ticket/3287) a couple of days ago. The patch adds some methods into and changes the existing methods in the CaptureHelper module. It should not, as I can see, affect any existing Rails implementations. I added the relevant unit tests and all but one of the tests pass. The test that fails failed
