similar to: T1 (hardware pre-shaped) shaping question

Here is what I am trying to do... I want to set it up so any traffic coming or going to a specific host is ran through 3 HTBs. Two of the HTBs are for limiting incoming and out going and I want them to then dump the traffic into the third for limiting overall bandwidth for that host. I have been using tc filter to put it into the HTBs for incoming and out going, but am having problems getting it

I''m trying to shape each machine on an interface to 256k each, but I''m getting stuck and only able to shape an entire interface to 256k. What should I be doing differently here? tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb default 10 tc class add dev eth0 parent 1: classid 1:1 htb rate 100MBit ceil 100MBit tc qdisc add dev eth0 parent 1:10 handle 110:

Hello all, I am running a coop satellite link for my aviation company here in Iraq. (silly blog www.stardotstar.org). I am running tc with htb with good success so far. I am working on improving it though and need some help. Currently I have just 4 classes, syn/ack/ping, webchat, http, and then other. We are really happy with how this has improved our ability to call home from our rooms and

Hello every one! I''m making a project to a discipline in the university and the project is make a Linux router that grants QoS to Multimedia connections (the prof. say we can use Open Source Soft. :) or reinvent the wheel). I have been googeling and googeling and i found the l7-filter in source forge and the spectacular simple language that is TCNG. Well the problem is how can i

Hi all, Can someone please help with a tcng setup? I have played with tc and tcng in the past, and now would like to get some serious rules in place. However, I have a difficulty in setting them up. My setup is as follows: One machine working as a firewall: eth0 is the interface connected to a 512K DSL line eth1 is connected to a LAN eth2 is connected to another LAN, a bit like a DMZ eth1 and

I''ve been having a bit of difficulty with a hierarchy of HTBs that I''m wanting to create. Essentially, I''ve got one interface that goes to both the DMZ and the internet. When going to the internet, some of the traffic will be going through a VPN and therefore I want to prioritize it differently, however I want to give the DMZ traffic full speed as long as it

Maybe a strange request, I''ll try to explain this as clearer as I can (forgive my bad english, please :-) ). I''m setting a linux box as a router. My router uses multiple routing tables, so I can address the traffic from specific ip addresses of my lan to distinct ISPs providers (specifying a different default gateway fo r each table), marking packets with iptables

This is more of a NF question but it is tightly related to LARTC as well. In the following example: -t mangle -A PREROUTING -i eth0 -j MARK 0x1 .... -t mangle -A INPUT -i eth0 -j MARK 0x2 Since MARK is a non-terminatring target, what would be the resulting mark on a packet comming from the outside and destined for a local process? Thanks P.S. I agree, the example looks stupid, but on the

Hello, world! Sorry to subscribe to the list only to immediately ask a question, but this one''s got me scratching my head and I can''t find the answer in the archives, the HOWTO, or on the web. Maybe I''m just asking the wrong question. Anyway, our Internet gateway is a Linux box. We''ve got two Internet feeds, a fast one from a crummy provider, and a

I am developing load balancing router, But I have a question about fail over. The follow diagram is my test environment and scripts. ------------------------------------------------------------------- Environment Setting PC1(192.168.10.2) | (LAN) | PC2-eth2(192.168.10.1) +

Hello, I am attempting to match on a single bit of the NF mark value, and after hours of reading and googling I can not get the syntax right. It got to be something very simple, yet I can''t find it. Any help will be greatly appreciated. Thanks! root@Arzamas:/etc/init.d# tc filter add dev wan_b protocol ip prio 2 parent 1:0 basic match meta\(nf_mark mask 0x80 eq 0x80\) flowid 1:0x80

Hi, I have searched the archives on the topic, and it seems that the list gurus favor load balancing to be done in the kernel as opposed to other means. I have been using a home-grown approach, which splits traffic based on `-m statistic --mode random --probability X`, then CONNMARKs the individual connections and the kernel happily routes them. I understand that for > 2 links it will become

Hi again, I keep posting about my problem with HTB -> http://mailman.ds9a.nl/pipermail/lartc/2005q3/016611.html With a bit of search I recently found the exact same problem I have in the 2004 archives with some graphs that explain it far better than I did -> http://mailman.ds9a.nl/pipermail/lartc/2004q4/014519.html and http://mailman.ds9a.nl/pipermail/lartc/2004q4/014568.html

Dave, In a post to LARTC on 18 Sep 06 you said "I run MRTG on all outbound traffic". I''m a newbie with respect to mrtg. I have rrdtool and mrtg built on my Linux box but I have no SNMP so "nothing works". Could you please provide basic instructions for implementing mrtg with respect to traffic shaping? What is needed? Net-SNMP? OpenSNMP? If yes, what is SNMP used

Hi friends, I haven't done such a simulation before and any help would be greatly appreciated. I need your guidance. I need to simulate end to end data for Reliability/survival analysis of a Pump ,with correlation in place, that is at 'Transactional level' or at the granularity of time-minutes, where each observation is a reading captured via Pump's sensors each minute. Once

Hi there, We''re running a small ISP and all the users are shaped to 384/512/768k both ways (whichever package they choose). The router is a linux (debian sarge), the kernel is 2.4.25 right now. All users are getting 10.1.1.* ip addresses (eth1) and eth0 connects to the isp using ethernet (via a media converter, it''s fiber from there). They''re nat''s using

During my tests I''m starting to feel stupid :). Traffic shaping works quite on its own. System: RedHat 7.3, RedHat kernel 2.4.18-18.7.xsmp, HTB version 3.6, interfaces eth0 and eth1 are acting as bridge br0. If TCP shaping almost works, it just exceeds limits UDP is not shaped. Traffic flows PC=>eth0=>eth1=>PC. Statistics shown is for just UDP traffic (1mbit of small udp

Hello. I have a linux server connected to a gigabit lan, and though that lan to a 768kbps/768kbps DSL modem. I''m trying to shape my webserver running on port 80/443 down to 512kbps, while leaving all other ports alone. The current configuration script that I''m using is as follows: tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb default 99 tc class add dev

(I know that what I''m wanting to do can be done, but for some reason I can not get it to work for the life of me. I think I have been staring at it too long and too closely.) I have two different internet connections from two cooperating ISPs. I also have a small 8 block of IPs that are globally routable that both ISPs will route to me via my world facing globally routable IPs that
