I want to build a "network simulator", to create scenarios such as delayed packets, lost packets, low bandwidth, or combinations of such. This document has been helpful for everything except the bandwidth: http://linux-net.osdl.org/index.php/Netem There is some documentation here regarding bandwidth: http://luxik.cdi.cz/~devik/qos/htb/ What''s the best documentation to read

Hi, Can anyone point me out where the script below is wrong? All I want is that host 172.31.1.1 can only use 10 megabit. If I run this script on the in-between router nothing happens (the host uses still the full 100 mbit, tested with iperf) , so i assume that something must be wrong.... #!/bin/sh # LAN1 NIC tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb tc class add dev

Hi, I find this diagram which details the kernel packet traveling : http://www.docum.org/docum.org/kptd/ Is it up to date ?

Hi, I''ve been working on hashing in tc for a month. Since there are only a limited number of avaialbe example on hashing, I''ll be appreciate if someone can my questions as follows: 1. tc filter add dev eth1 protocol ip perent 1:0 \ prio 5 u32 ht 800:: \ match ip src 1.2.0.0/16 \ hashkey mask 0x000000ff at 12 \ link 2: It seems that the hashkey make can only applied to ip

Hi, I am trying to put together a hashing filter based on example provided in LARTC how-to document. I want to link two hashing filters together where first one will use 3rd octet of an IP address as hashkey and second one will use 4th octet as hash key. How do I tell mask the address so that u32 filter uses 3rd octet as hashkey? Venkatesh K _______________________________________________

I''m hashing on a non-octet boundary, and it doesn''t seem to be working. I''ve got this set of filters, that does work: # root tc filter add dev eth1 \ parent 1: protocol ip prio 2 \ u32 # ht tc filter add dev eth1 \ parent 1: protocol ip prio 2 \ handle 2: \ u32 divisor 256 # flow tc filter replace dev eth1 \

hi I would like to ask is the following config correct for what I want to achieve ... Scenario: I have 3 networks 192.168.12.0/24, 192.168.48.0/24, 192.168.56.0/24 and most of the users use 1 IP, some of them more... If I make flat u32-filter search the box will make aprox/max 3 * 256 = 768 checks for every IP, so i''m deciding to deploy u32 hashes.. Here is the config I think to use

I have a question about a few things: ok when you have parent x:x and handle x:x link x:x flowid and so on. What is the max values of each of these, also where these or some of these hex numbers? I tried this on redhat 7.3 so there may have been some updates, but this is one of the tests I did. [root@RL1 root]# tc filter add dev eth0 protocol ip parent 1:0 prio 10 u32 ht fffe:: match ip dst

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 I have been playing with tc. I''m using htb and sfq. I tried to setup shaping of every ip address within a /20. I found that there must be an upper limit of about 2096 on the number of rules (classes, qdiscs or filters). I was testing a /20 which gives 4096 classes, qdiscs and filters. I''m using hashkey to optimize processing of frames. When executing the script below - it

Sorry for all the questions I''m just trying to understand how it all works. Thank you for your time. Is the following configuration possible? where ht 800 links to 3: for the 3rd Octet in the IP and then 3: links to 4: for the fourth Octet? tc filter add dev eth0 parent 1:0 prio 10 handle 3: protocol ip u32 divisor 256 tc filter add dev eth0 protocol ip parent 1:0 prio 10 u32 ht 800::

The index files already allowed the 'key[subkey]=...' syntax for keys, but considering such string as whole key. Proper split the parsing and the handling of the subkeys, so they can be searched a bit easier. This causes no actual behaviour changes, it is just internal micro-refactoring. (Thanks Rich for the hints, too.) --- builder/index-parser-c.c | 15 +++++++++++----

Hi all, I am a newbie and I have not played a lot with tc utility. I have red maybe everything that has to do with massive filtering (maybe not everything). If you can help me on this I would appriciate that very much. I use tc utility with iproute2-ss040831.

Hi I''m setting up shaping using HTB and hashkey. It seems like there is a limit on the number of classid''s at 10000? How can I go higher than 10000? This is what my output say when I reach classid number 10000: ... ... /sbin/tc class add dev eth0 parent 2:6 classid 2:9998 htb prio 5 rate 768kbit ceil 768kbit burst 0 cburst 0 /sbin/tc qdisc add dev eth0 parent 2:9998 handle

Hello! I have a quite complicated setup. In my network on each interface there is bandwidth limitation for each user. Booth outgoing (on interface itself) and incoming (attached IMQ) traffic. There is main HTB class which limits bandwidth for whole interface and HTB subclasses for each user. Filtering is done with hashing filters. This setup was working correctly. But now in the network I
