Hello there, Having made quite a lot of expensive mistakes i have finally clobbered together a script for the users on my network. Have a look at it and please suggest as to how can i limit bandwidth to each ip on this network to about 64Kbits.

Hi all I am conducting the experiments comparing IP router forwarding delay and MPLS LSR forwarding delay, it is obvious in theory MPLS in Core should be faster than IP, but for small netork (only have several core routers), result show it is not, this is why I want emulate a large IP routing table in one core router. can I do it and how ? right now I use static routing table (by using command :

Hi. I wrote in a reply to a mail on here recently that you can''t set mpu (minimum packet unit) on HTB as you can on CBQ. I''ve just noticed that there is a patch on devik''s site which does mpu and overhead. http://luxik.cdi.cz/~devik/qos/htb/ For dsl users mpu is, for practical purposes going to be 106 - overhead is still variable though, depending on packet size.

Did anyone see the article? It''s the first time I really noticed that these little Linksys routers are such a fully fledged linux machine with a decent processor and a replacable firmware. I am now itching to get one to replace the multipurpose firewall desktop machine. Has anyone experimented with the current state of the firmware and how advanced you can get with tc rules? For

Hi I''ve searched the archive for a solution where I want to limit/shape WLAN users. I only know''s their MAC, because they get their IP from dhcp. > Why not, just use negative offsets with U32 to access >the 14-byte eth frame header before the IP header: > >Decimal Ofs Description >----------------------------------- >-14: DST MAC, 6 bytes >-8: SRC MAC, 6

I have been trying to optimise my ADSL connections for VOIP. Funny things were happening - for example increasing the ping packet size by 50% had no effect, but then adding one byte had a major effect. It took me a while to figure out that I was seeing the effects of the fixed ATM cell size. This is probably obvious to some of you. For the rest: ADSL uses ATM as its transport. An ATM

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

Hey, I''ve been scouring the web these past few days trying to find a suitable technique to load balance my network. Unfortunately I think my setup is very uncommon, so I''m looking to you guys to see if you can help. I currently have 2 ADSL modems, provided by the same ISP and terminating on the same gateway (I think having the same gateway is what is causing the problems, since

Hi, In my LAN Iam trying to make following setup: - All the traffic generated by 10.0.2.1 should go to 10.0.2.11, If the destination of this traffic is internet than it should be placed on its interface eth1. Outgoing traffic on eth1 should be shaped.For this I am using fw filters and cbq. _______ 10.0.2.1 -------> 10.0.2.11(eth0 )----| A

I am using HTB+IMQ on an Ethernet bridge and tc for statistics reporting. I am finding that tc reported rate is about 5-10% less than that reported by IPTraf for the same traffic. Has anyone observed this before? Which is more accurate? Rajesh

Hello I am using htb (krenel 2.6.14.3 + esfq patch from fatooh.org) to limit the bandwidth. But I want the absolute maximum rate to be for example 5Mbit and not to exceed it. here is the script: $tc qdisc add dev ${NETIF} root handle 1 htb r2q 4 $tc class add dev ${NETIF} parent 1: classid 1:21 htb rate 5Mbit ceil 5Mbit $tc class add dev ${NETIF} parent 1:21 classid 1:101 htb rate 2Mbit ceil

Hi List. First post, be gentle please. Is there any limit in the linux UDP rate? I am using linux kernel 2.6 and iperf to measure bandwidth between two endpoints connected by 100 Mbits ethernet. Running (as root) iperf -u -s and iperf -u -c always gives me 1.05 Mbits/seg even when runned in the same machine. Can somebody clarify this? Thanks in advance. Sebastian

Hello all! I have a small LAN at home and when someone starts to download (only one), interractive traffic (www, chat and online games) is impossible with standard kernel queues setup... So I started to shape. My ISP gives me a 512 kbits link to the Internet and a 100 Mbits link to some of the other big ISPs in my country. If I set the rate of the parent htb qdisc at 512 kbits, I will never use

Hi; First, sorry if this question is mostly netfilter related, than lartc, but I think you guys may have a your opinion about this. I''m using Linux 2.4.x with netfilter packet filtering / NAT on our front-end firewalls (P500 with 1Gb RAM), which are filtering traffic going to our Public Web Sites. The traffic is growing very fast since several months.. The average traffic filtered by

Hello everyone, I''m a newbie experimenting with CBQ shaping and am facing a few problems. Can any of you please help?

Hi all, ive got wondershaper working well with the highest download while maintaing minimal latency but the problem is this: ive got 2 nics in the linux router eth0 and eth1. eth1= internet interface but this is connected to a router say 10.0.0.190, now off that router there are other servers, mail server, domino server etc now if i shape on eth1 ingress and egress using the wondershaper script

Hi guys, I''m running a freenas domU (FreeBSD 8.3 based, ZFS v28, 2 vcpus mapped to the same HT capable core) to serve storage for all purpose including other domUs running on the same host. I did some study to understand how well it works and the result is kind of confusing. In summary, the network performance between domains on the same host is worse than expected. And NFS service to

I am using hostap driver as an Access Point and want to shape on this wireless interface. The thing with hostap driver (and others i think) is that it creates new virtual interfaces (wlanxxx) for every node that associates with it. Lets say i want to limit all outgoing traffic on wlan0 at 512 Mbits. The problem is that i cannot apply an htb configuration on wlan0, beacause some traffic is handled
