Hi! I am studying HTB. I used the topology showed below: 10.1.0.1 ------ 10.1.14.25 (eth1) / 192.168.10.10 (eth0) ----- 192.168.10.11 (host 1) (router) (host 2) All machines use Debian Etch. Has a Iptables masquerading rule to eth1 in the router machine . The NICs are 100 Mb/s. The host 1 has Apache 2 and a file with 670 MB (CD ISO image) to download. When I used

I can use DSMARK to mark on the Egress side. Is there a way to mark/change the DSCP value of an incoming packet on the ingress side? Thanks. Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7

All: Does anyone know what the burst and cburst parameter do? My understanding so far: * I see a lot of different definitions on the web. It seems like burst is the number of bytes sent before serving other queues/classes. So if burst was 1000 bytes and class rate was 100kibit per second. It would send 1000 bytes each time the scheduler service that queue to a rate of 100 kbit per

Hi there! I''ve using HTB for a while and now I an faced with a ''problem''. How hierarchical is HTB? Let''s say I have this 3 layer HTB setup: root class 1: (rate=100, ceil=100) 1: children classes 1:10 (30,100) and 1:20 (70,100) 1:10 children classes 1:100 (10,100) and 1:101 (20,100) 1:20 children classes 1:200 (30,100) and 1:201 (70,100) I managed to have

Hello, I''m using a script with tc, to limit my outgoing traffic : tc qdisc add dev eth0 root handle 1: htb tc class add dev eth0 parent 1: classid 1:1 htb rate 500kbit burst 6k tc filter add dev eth0 parent 1: protocol ip prio 1 u32 match ip dst 172.28.54.9 flowid 1:1 I want to test bandwidth with iperf to see if limitation is correct. Sometimes, I get correct measure for certain rates,

Hello, I am trying to mess with a prio type qdisc, and must be missing something. Here''s my sample code: tc qdisc add dev eth0 root handle 1: prio tc filter add dev eth0 parent 1:0 prio 1 protocol ip u32 \ match ip dst 208.0.0.0/8 flowid 1:1 tc filter add dev eth0 parent 1:0 prio 3 protocol ip u32 \ match ip dst 0.0.0.0/0 flowid 1:3 I would assume that any traffic going to

I''m trying to configure 4 queues with strict priorities based on DSCP. I tried to following commands, but it seems that the filters I defined have no effect tc qdisc add dev eth0 root handle 1: prio bands 4 tc qdisc add dev eth0 parent 1:0 handle 10: pfifo limit 100 tc qdisc add dev eth0 parent 1:1 handle 20: pfifo limit 100 tc qdisc add dev eth0 parent 1:2 handle 30: pfifo limit 100 tc

All: I have been told that HTB_HYSTERESIS might have some effect on rate calculations. This file is usually in /usr/src/linux/net/sched/sch_htb.c. If I change this file I have to re-compile. I am not quite sure how to do this. Can someone list the steps necessary to re-compile or point me to a doc that explains how to do so. Thanks. Jon Flechsenhaar Boeing WNW Team Network Services

Dear all, I''m making a script to implement DiffServ policies with HTB. Here it is : if test $1 = "help" -o $1 = "h" -o $# != 5 then echo "usage: ds.sh <DEVICE> <DS_RATE> <EF_RATE> <AF_RATE> <BE_RATE>" exit fi DEV=$1 DS_RATE=$2 EF_RATE=$3 AF_RATE=$4 BE_RATE=$5 sync tc qdisc del root dev $DEV tc qdisc add dev $DEV root handle

Hi to all I am studying HTB on LARTC how to. I realize a simple configuration on router: tc qdisc add dev eth0 root handle 1: htb default 30 tc class add dev eth0 parent 1: classid 1:1 htb rate 3mbit burst 15k tc class add dev eth0 parent 1:1 classid 1:10 htb rate 2mbit burst 15k tc class add dev eth0 parent 1:1 classid 1:20 htb rate 1mbit burst 15k tc qdisc add dev eth0 parent 1:10 handle 10: sfq

Hi Dovecot folks, I recently reported this bug in Debian (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=939442) after a stretch -> buster upgrade, however since I can reproduce it using the latest 2.4 from git I thought perhaps I ought to take it straight upstream. Here's the text I provided Debian about the issue, and below that I've included a syslog snip showing the same issue

Hello mailing list, i stand bevor a mystery and cannot explain it J. I want to do shaping and prioritization and I have done these following configurations and simulations. I can´t explain, that the combination of PRIO and TBF is much better than the HTB (with the prio parameter) alone or in combination with the SFQ. Here are my example configurations: 2 Traffic Classes http (80 = 0x50) and

Is there anyway to actually see packet stats or that packets are for sure going into a prio queue with TC? I can see all the HTB stats but the prio classes just list as being there...would like more information Basically I have the following setup DSMARK | HTB - (tcindex filter on TOS) | Prio (u32 filter on TOS) Thanks Jon Flechsenhaar Boeing WNW Team Network Services

Hi, I''m trying to divide my bandwidth between different services, but I''d like to take into account the number of active users. For example, l want divide my bandwidth between HTTP and SMTP and guarantee HTTP 80% of the bandwidth.

I want to limit pps (packets per second) not just bandwidth on the ingress side. I can do this using IP tables but I''m curious if there is a way to do this with TC. Thanks. Jon Flechsenhaar Boeing WNW Team Network Services (714)-762-1231 202-E7

Dear list, I want to rate-limit a couple of customers in both up and down directions. They get a different speed for traffic staying on our network than for traffic towards/from the internet, so that''s a master class and 2 child classes per customer per interface. I made a test setup with cbq which worked, but wasn''t too reliable I measured a tolerance of about 30%. I read

Hi! I''m trying to limit the uplink bandwidth using htb but no packets are overlimit or dropped. :-( My router config: * Linux kernel 2.4.20-pre10 (htb v3.7) with everything built as modules in QoS, iptables in use. * tc binary from htb3.6-020525.tgz * external interface eth0: Internet access, 512 kbit/s uplink speed * internal interface eth1: internal LAN, 100 Mbit/s The hosts in the
