similar to: u32 hash-es ?

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 have 2 class C 80.97.103.0/24 and 81.180.12.0/24 but i dont konw how to set hashing tables for HTB tc add dev eth0 parent 1: prio 0 handle 1: protocol ip u32 divisor 256 tc add dev eth0 parent 1: prio 0 protocol ip u32 match src 80.97.103.0/24 hashkey mask 0x000000FF at 12 link 1: but i want 2 hashkey for 80.97.103.0/24 and for 81.180.12.0/24 can somebody help me ?

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 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

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 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. I want to limit bandwidth for the 192.168.0.0/16 subnet using this script. tc qdisc del dev eth0 root tc qdisc add dev eth0 root

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 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

What is the difference between lines below? $TC filter add dev imq0 parent 1:0 prio 5 handle 1: protocol ip u32 divisor 1 $TC filter add dev imq0 parent 1:0 prio 5 handle 2: protocol ip u32 divisor 256 What divisor is doing? And the last problem... $TC filter add dev imq0 protocol ip parent 1:0 prio 5 u32 ht 800:: match ip src 10.0.0.0/16 hashkey mask 0x000000ff at 12 link 2: Why after ht

Hello I have 2 class-B networks (172.22.0.0/16 and 172.23.0.0/16, over 130k of ip''s) and need to setup traffic tbf shapers with 64kb/s for each ip from 172.22.0.0/16 and 128kb/s for each ip from 172.23.0.0/16 just read lartc and don''t understand how to use u32 for decreasing number of rules and hashing

Hey all, I had asked a question a little while ago about CPU usage being outrageous while using tc and a cbq qdisc. Ed was very kind and offered a few suggestions. One of these was to look at hashing. So after pounding away at it for about a week, I have a general understanding of how it works and have tried to implement it. Unfortunately, and quite obviously since I''m posting here, it

iproute2 distribution in README.iproute2+tc includes toward the end an example of usage of syntax ''offset mask'' as follows: # Lookup hash table, if it is not fragmented frame # Use protocol as hash key $TC filter add dev eth1 parent 1:0 prio 5 handle ::1 u32 ht 800:: \ match ip nofrag \ offset mask 0x0F00 shift 6 \ hashkey mask 0x00ff0000 at 8 \ link 1: Also, identical

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 Timo, With dovecot 2.1.rc1 (056934abd2ef) there seems to be something wrong with virtual plugin mailbox search patterns. I'm using a virtual mailbox 'unread' with the following dovecot-virtual file $ cat dovecot-virtual * unseen For testing propose I created the following folders with each containing one unread message INBOX, INBOX/level1 and INBOX/level1/level2

hi i''m using htb + u32 filters, and i was wondering if there is something one can optimize at this stage. i have a lot of filters (~ 50.000 / interface, and there are two interfaces), and around 4500 classes / interface. the traffic going through this machine is something around 210-230mbit/s at 50kpps. as you can imagine, the load is pretty high. in fact (as it''s a dual xeon at

Hi all, I analysed my data with lme and after that I spent a lot of time for mean separation of treatments (post hoc). But still I couldn’t make through it. This is my data set and R scripts I tried. replication fertilizer variety plot height 1 level1 var1 1504 52 1 level1 var3 1506 59 1 level1 var4 1509 54 1 level1 var2 1510 48 2 level1 var1 2604 47 2 level1 var4 2606 51 2 level1 var3

Hi, I need to set filter-hash and use source-port as hashkey. It seems that I can''t use "hashkey" without using "match". I am using following commands: tc qdisc add ... root handle 1:0 htb # Loop to add 1000 classes (i = 1 to 1000) tc class add ... parent 1:0 classid 1:$i #set filters tc filter add ... protocol ip parent 1:0 u32 tc filter add ...

I forgot to ask a few more. Is there a relation between the hashtable ID /(parent,handle) so that if I used 2: for a hash table I could or couldn''t use 2: for a (parent,handle)ID? I also noticed that you type the hashtables like 2:2: can you have more levels with this? like 2:2:2:1: ? and I guess the same question with the parent/handles. thanks again. -- When dealing with a slow
