hi i wanted to get the qdisc stats without using tc. is this possible by just using rtnetlink sockets directly? if possible could someone point me to an example. thanks. __________________________________ Do you Yahoo!?

Hi , I''m trying to call the tc_qdisc_modify function of tc in iproute2/tc. I could compile it with my stub program and got the executable. However, when i try to create an htb qdisc i get the following error : Unknown qdisc "htb", hence option "default" is unparsable However, if i use the tc tool, it works fine.. When I tried to understand the problem, it appeared to

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

The Linux QoS Library (LQL) provides a GPL licensed, GObject based C API to manipulate the network queueing disciplines, classes and classifiers in the Linux kernel. LQL does not use the TC command as a back-end. Instead, LQL communicates with the Linux kernel via Netlink sockets the same way TC does. 0.5.0 2004-08-30 ----- * Initial public release. * I wanted to get 100% API doc coverage and a

Is there any library that i can hook on at runtime in order to create a qdisc dinamically from a program or if i want to do this I have to call the "tc" command? The disadvantage of calling the tc command from a process is that it creates an other process and this slows things up. Marius

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

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 ?

Hi I''m working actually on a project about Qos configuration on a linux computer. I need to access (read/write) at the informations generated by the "tc" command. I think that these informations are in the /proc/net/psched file, but I only got 4 hexadecimal number in it.. Can anyone help me? David

Hello everybody, I am new to the lartc mailing list. I have been using "tc" for some time now. To be precise, tc & HTB to shape traffic. I did a lot of search on Google for 2 things: - A GUI to create configure new qdiscs & classes for HTB - A utility that will graph the data sent through all configured classes or qdiscs. I could not find anything. Could someone tell me if a

Hi all, I try to made a C program (CAC (Call Admission Control) module) and I don''t want to use a exec command with TC in my program when I want to add,modify or delete a QoS rule. I search a TC library and I found two projects : LQL (Linux QoS Library) : http://www.coverfire.com/lql/ (c) LTCM : http://hng.av.it.pt/~ltcmmm/ (c++) Do you known these API or others ? If you know them, can

Hi, A thought for the list. As I mentioned in another posting, there are a lot of QoS mechanisms out there. Linux supports some, but not all. Some patchsets add others, but don''t work for all kernels. There are also userland implementations, usually sitting in software routers, but there are other packages. Would it be helpful if I worked on a table of what''s out there for

Hello, I have read most of the relevant emails already posted to the LARTC mailingilist and I have not found a solution to my problem. What I am trying to do is: limit the HTTP output traffic to 30Mbps and also to limit each HTTP connection at 512Kbps, if the client downloads more than 1MB. I have managed to limit the total traffic but not the traffic of each HTTP connection. Here it is my

hello, I would like implement an academic theory of TCP traffic control gateway for wireless multihop environments. The main part is an dynamic pacing witch suffers from the RTT and hops in the wireless domain. With shell-scripts or how ever I can get my information for the actually pacing-time for an TCP-stream - the time can be chance over established TCP-session - so it''s be a

Hi, Can we create TC rules for an interface alias? Here are the commands: /sbin/ifconfig eth0 add ip.ad.dr.ss netmask m.a.s.k up tc qdisc show dev eth0:0 Last command throws error "can''t find device". Is there any way to define tc rules on alias or is it simply a limitation? Thanks, Deepak _______________________________________________ LARTC mailing list
