Hi, I made a prototype for a real-time qdisc and ip bandwidth monitor, it still is not mature, but can be of some use even as it is. To try it : http://clowncode.net Clowncoder

Hello, I am interrested in the monitoring of the qos qdiscs parameters such as size of the queue, enqueues, dequeues, delay in queue, I made a tool to have those results availlable at http://rawsoft.org, but it will probably not work anymore because of the kernel evolutions (the file sch_red.c is patched for the tool to work). I would like to have all the necessary data coming from the kernel

Hello all, I have using htb for last 10-12 months to manage the bandwidth share. Until last month everything was ok, but now after a kernel upgrade (from 2.4.20 to 2.4.26 because a kernel bug that generate a oops) the Linux router is droping packets. It is weird because the "tc -s class ls dev eth1" (in the class I monitor) reports no packet drop, the "tc -s qdisc ls dev

Did anyone ever answer this one?

I have managed to dynamically parse the output of commands: tc qdisc ls dev eth0 and tc -s class show dev eth0 Save statistics in an rrd database and display it via a php script. see http://143.233.4.215/graph.php and dload scripts from http://143.233.4.210/qos/ My next step in developing this monitoring software is to somehow manage to create a tree out of tc and then use it to greatly

With the advice of Thomas Graf, I have modified the qdisc monitoring tool. A new qdisc called spy can be gafted in any qdisc tree and bring back detailled information that is shown with curves. Try it if you want real time visualisation of enqueues, dequeues, delay in queue, queue size. It is at http://rawsoft.org Vincent. _______________________________________________ LARTC mailing list /

... is on SourceForge, http://tcng.sourceforge.net/#src Besides a bunch of bug fixes, this release also contains a greatly improved version of the comtc utility that copies comments from the tcng source to tcc''s "tc" output. There are a few infrastructure changes to make comtc work smoothly: - tcc''s -E option is now called -Wexperror or -Wexppostopt, respectively

Hello, I have a problem with my GNU/Linux router. I mean, I am trying to configure a VPN conection for the clients of the LAN and allow to connect them to the Internet trought the router. I have installed in the server a QoS policy and I have configured the firewall for allowing all the clients to connect. I attach the script. The idea is that when a client connect this pc the dhcp gives him an

I had a linux wireless router. I would like to monitor the queue lengh of the wireless interface. By default, the wifi0 interface is with pfifo_fast qdisc which does not report backlog packet. I replaced pfifo_fast with pfifo: ''tc qdisc replace dev wifi0 root pfifo'' Then I use iperf to send UDP pkts faster than the interface can handle but when I read the qdisc, the result is

Hi, I''m a relative newbie to LARTC but I have read Matthew Marsh''s book and lurked on this list for a while.... I still seem to be missing a few key ideas here.... So... Maybe folks on the list will be kind enough to help. I have two different ISPs. Cogent and Bell. I have three different firewalls (2 PIX and 1 IPCop). And I have an Ubuntu Linux box doing LARTC for around

Hi, I have 3 internet connexions : Router 1 : 192.168.212.2 Router 2 : 192.168.212.3 Router 3 : 196.200.8.73 I can''t change IP adress of router 3 because I haven''t admin password and my provider don''t want to give it. I want only 1 PC to aggregate the 3 connexions. How I can make that Router 3 work on my 192.168.212.x network? Thanks Jeremy

Hello all. We have three tunnels over the internet between our "central" gateway and some branch office gateway. Each gateway has eth0 on its LAN an eth1 on the internet. We use DSL lines and eth1''s have the internet IP directly attached on it. Each gateway, also, acts as iptables NAT gateway. The outgoing bandwith is 300 kbit, and we tried this (i.e.) on each tunnel: tc

Hello! I like to announce sch_ooo, a new queue discipline that, attached to a class (or a device, as root) reorder the packets that pass by delaying some. Example: tc qdisc add dev eth0 root ooo limit 100 gap 4 wait 1100 This queue will create a pfifo with limit 100 and will delay every 4th packet with 1100ms. An stream of 6 packets like this: 1 2 3 4 5 6, generated by ping will be reordered

I always took that as mandatory.

As a necessety for my job is to real-time monitor the bytes, packets, packet dropped etc of all the qdiscs working inside the kernel i''ve tried varius methods: 1. Parse tc -s command output and update a round robin database and use rrdtool to graphically display tc statistics. [varius perl scripts exist for the above job] 2. Unsuccesfully tried QoS SNMP extensions, in order to use a

Hello, I use HTB with linux-2.4.20-ac1 and iptables-1.2.7a (pathced for IMQ). I configured one HTB qdisc on an IMQ device. This qdisc has some classes (about 5) and all of the classes has qdisc pfifo. I sometimes got out from my linux (while I was working) and I found in logs: Dec 4 11:49:27 core kernel: HTB init, kernel part version 3.7 Dec 4 11:49:28 core kernel: HTB: quantum of class

Hi. I am trying to bend my brain around ''tc'' and friends and am failing so far. I need to set up a bridge which limits the packet rate to 2000 packets/s, but with the added twist that packets with a certain DSCP value must be given absolute priority in both directions. The packet rate limit thing appears to be easy: brcfg addbr br0 brcfg addif br0 eth0 brcfg addif br0 eth1
