how to setup massive traffic shaping? (2 class B nets)
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

Question on hashkey
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

tc limit
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

TC Hashing Filters
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

deleting tc rules
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

u32 hash-es ?
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

Hashing filters
Hey A wise man said to me that Hashing filters was my solution to rock the world, and making my life alot easier. When applying 4000 rules, the system had to check them all for match. But with hassing it would only require 1-2 checks. Even though when i had read the lartc on the subject i was no less that a question mark. If anyone have played with it, and have a working, logic configuration

more questions.
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

No, there?s a fairly common hack around this problem: ibase=A and obase=A *always* means ?base 10? regardless of the current base, due to a quirk in the way values

filter performance/optimization questions
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

Large number of HTB classes
I am planning a setup with thousands of classes in a HTB qdisc, say from 1:1000 to 1:2000, each with a very small rate and a big ceil, for fair sharing of a 45mbit link. I suspect some problems could be lurking in there. Anyone having good/bad experience with such number of classes?

Failed to find DC in keytab, gpupdate fails
Try verifying kvno from the client that gives the error message. That kvno = 2 for dc$ must've come from somewhere. You can also double check e.g. via ADUC ldap attributes of the dc$: lastpwdset and kvno. If  kvno is definately 1 that means that client connecting has some error, if it's 2, than it means that dc has outdated keytab. And if it's the former, than I really am not sure

Hello CentOS List Members, Thoughts as to why my BC functions aren't properly converting between bases? Decimal to binary or hex works fine, but not binary or hex to decimal and so forth. No doubt the syntax is in some way wrong, but when I test from the CLI and the right values are returned, I have to wonder. Other than a few other define statements, the only other option I have set is

Failed to find DC in keytab, gpupdate fails
what is the output of "kvno dc.domain.net.pl"? There seems to be mismatch kvno of the secrets keytab, and what is client expecting (kvno 2). Kvno increments by 1 for every password change. Was there by any chance password change for the dc$ account and keytab was not recreated? If You made some upgrades, maybe during process You for example rejoined the domain (that would set new
