...is the best way, I think. "u32 match mark vvvv mmmm" it''s intuitive but breaks a little the levels, "u32 mark vvvv mmmm" it''s ok but not intuitive.... If you want I can rewrite it if you want.

I''m a new comer. I have problems using tc+htb. I run the following commands, and expect outgoing ssh flow goes into 1:11. But actually it goes into default 12. What''s wrong? tc qdisc add dev eth0 root handle 1: htb default 12 tc class add dev eth0 parent 1: classid 1:1 htb rate 1000kbit ceil 2000kbit prio 1 tc class add dev eth0 parent 1:1 classid 1:11 htb rate 100kbit ceil

Hi all, Is there anyway to have more than 2 dummy interfaces? I need more of them but the system refuses to create it :P How can avoid this issue? Thanks.

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

Dear All, Would you guy have any advices concerning how to get some data like queue length, pkt size, and so forth, from the running queue. Right now, I modified the queue disc to print out some info I want using printk() and use syslogd to catch those info up. The problem is, in burst, syslogd can''t catch all the msg the queue sent out. Are there any standard or better way to

Is it possible to create 1 filter rule using fw selectors AND u32 selectors?

Where can I find examples of configs to emulate WANs, I am looking for slow speeds and high latencies. Thanks

Hi, I am new to kernel programming. My task is to route packets from different hosts through one single token bucket filter as we are trying to model a wireless scenario with many hosts communicating and sharing the same bandwidth.So the idea we came up with was to route packets from different hosts to user space using Netfilter and then send them through a common tbf implemented in user space in

Hi, I''m interested to write rules direct in Kernel space memory and not to execute the tc command. Have anyone done this before ? Any ideas ? Sources ?

Can someone verify that using fw as a filter in iproute2-2.6.11-050330 is broken. Doesn''t seem to work in any case and I saw an earlier post that would lead me to believe this is the case. If so does anyone have a temporary fix? Thanks, Troy

I''m getting the following error/warning at some point in my config script, and I''m not sure which class it is referring to. htb: class 10007 isn''t work conserving ?! I [think I] understand that htb is a non-work-conserving qdisc, and I [think I] have configured things so that every htb qdisc I instantiate limits the bandwidth, so I don''t understand why this

I''m successfully using HTB + GRED to shape traffic based on the DSCP field. I would like to strip the DSCP and possibly replace it with normal ToS bits on egress traffic leaving my network. Leaving DSCP set is pointless, and could potentially cause problems with some ISPs that use DSCP internally I suppose. Setting ToS bits would seem ideal as most networks still honor it to varying

Anybody knows allready programmed libraries either java or C to create/destroy queues?

Hi, I''m trying to set up a tc filter rule matching the following conditons: source ip is 192.168.0.68 and only packets shall be matched going out on the internet connection. My first try was "protocol ip u32 match ip src 192.168.0.68 ! match ip dst 192.168.0.0/24" but obviously tc doesn''t like the NOT ... ;-) I also tried the route classifier, but it cannot be

Hi! I can''t find anywhere correct syntax how to match TTL. All of I found refuse to work :( tc filter add dev eth1 parent 1:0 prio 10 u32 match u8 64 0xff at 8 flowid 1:11 tc filter add dev eth1 parent 1:0 prio 10 u32 match u8 0x10 0xff at nexthdr+13 protocol tcp flowid 1:11 tc filter add dev eth1 parent 1:0 prio 10 u32 match u8 0x10 0xff at nexthdr+13 flowid 1:11 All I need is to

I''m looking for a way to configure a qdisc or filter to drop all packets. The logic behind this is that I''m using the u32 hashing tables to get move my filters from iptables to tc filters. This will translate into much less per-packet processing for me. However, I need a way to drop any packets that don''t match any of the filters. Paul C. Diem PCDiem@FoxValley.net
