similar to: how can I monitor a (dumb) switch ?

Hello there, Can someone please explain why do one neeed IMQ ? I can already shape incoming traffic on my nat router by creating qdiscs on LAN-side interface. I have done some tests, whith simple bandwidth limmiting, and it works. I''ve read just about all the stuff on www.linuximq.net ... but couldn''t make myself an ideea on why would someone need IMQ for ingress policing ...

hello, I am trying to find where filtering is done in order to drop packets randomly there (eg.10%of them) for a testing purpose in a school project. I want to do this after packet is filtered and before being sent. I d aprreciate if you could help or suggest. Thanks.

Hello, list members, can i limit pps rate with linux? How? -m limit does not fit, as i understood: it can help with low rates only (is that true? any suggestions?) Thank you, -- _,-=._ /|_/| `-.} `=._,.-=-._., @ @._, `._ _,-. ) _,.-'' ` G.m-"^m`m'' Dmytro O. Redchuk

hello, i have a question: - which one is faster: "tc filter with u32 match per dst ip" or "iptables match per dst ip with target CLASSIFY"? - this question is for large rulesets (over 500) thank you, cristian carstea

Hi all, updated py-htbstat: http://www2.ldc.net/~dor/py-htbstat/ Some screenshots: http://www2.ldc.net/~dor/py-htbstat/shots/shots.html It''s now possible to use classids in form ''xxxx:xxxx'' now (actually i dont know why i''ve made it to use ''1:xxxx'' only :-) -- _,-=._ /|_/| `-.} `=._,.-=-._., @ @._, `._ _,-.

Hello Everybody, I have configured a Linux box that does traffic shaping. Its working wonderfully fine, just as expected...Now i want to measure the bandwidth consumed by each of my hosts....But I dont want SNMP to run on all the hosts[as required by MRTG] I used iptraf on my linux box, but it only measures the bandwidth on interface basis only.... I tried installing traffic-vis, its not working

I have linux box (does nat and firewall for small network) connected to dsl. I want to set priorities for protocols (that nothing could disturb web browsing). This is my rules (eth0 connected to internet): /sbin/tc qdisc del dev eth0 root /sbin/tc qdisc add dev eth0 root handle 1 htb default 30 r2q 100 /sbin/tc class add dev eth0 parent 1: classid 1:2 htb rate 900Kbit burst 15k /sbin/tc class

Dear all, I am having problem using iproute2 on my new Slackware 10.1 box.

Hi, I want to stop routing for 1 particular host in my network. I thought that this would do it: iptables -D INPUT -d aaa.bbb.ccc.ddd -j DROP iptables -D INPUT -s aaa.bbb.ccc.ddd -j DROP But that still shows traffic. What is the corract way to do that?

Hello I have question, currently using linux box as router. It only route packets. Currently there is 80k packets/sec and this cause 90% CPU usage on Intel Celeron 3ghz CPU. Did multiprocessor system like 2x XEON DP 3.4ghz will divide CPU usage between 2 CPU and will allow double routing performance ? -- Golem

some body can advise me about how to create burst traffic two type is 1. ICMP burst traffic (i need to create general and normal data burst traffic but i don''t have any idea to do it) 2. Real time traffic (i think may create by open real-time streaming with a big file from real-time server but i don''t sure it will work!) thank you raku

Hi can anybody tell me what is the best and right way to gather statistics from htb.init usage in graphics or in any other format cause it''s pretty uncomfortable to view statistics in text when you''ve got 4 interfaces and enough filters and queues Thank you ! Dzmitryj Jakavuk

Hello, I have been working on tc class . But when the classid reaches 5 digit , it DOES NOT ACCEPT THAT ... see the example below :: tc class add dev eth0 parent 10:36 classid 10:13310 cbq bandwidth 10Mbit rate 32Kbit allot 1514 weight 3.2Kbit prio 5 maxburst 20 avpkt 1000 bounded See the bold digit !! this command doesn''t work , but if i use with 4 digit then it works : tc class

Hello members. I wanted know if htb shapes download speed and upload speed too? i want to give a client 128/64. so is it possible to give 128 download download speed and 64 upload speed.I mean 2 way traffic control. _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Hello, I''m using HTB and would like to ask is it correct to put "PRIO" on non-leaf classes ? I know that on leaf classes it''s correct and determines how the excess bandwidth is distributed among non-leaf classes. Thanks Nikolay G.K

I would like to limit the amount of bandwidth each IP in a network gets. For example I have a network that runs at 10mbit. I have a class C 192.168.1.0/24 that makes up this network. Is there any simple way I can say each IP in that class C gets 56k with out making a rule for each IP? Thanks, Rob Kobiske _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl

Hello, i am writing a GUI for the tc. I am almost there, but i need some guideness... For every class/qdisc i have the bytes sents, dropped, borrowed, overlimits data for statistics, and i want to plot them on a graph. What data and how would yuu find it usefull to see plotted on a graph? I need you answers ;) I will post my GUI soon :)

Hi Is there a program which allow me to see how "my" traffic goes through my iptables rules? Which accept it, which deny? Right now my router has a little bit of traffic and its hard to see only mine traffic. -- Miłego Dnia Krystian Antoni _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
