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, I''m a complete newbie at this traffic shaping / QoS stuff so please excuse me if this is a silly question. I''ve searched and searched on Google and I just end up confusing myself even more, so I thought I''d post my question to this list and see whether someone can help me! Basically, I am running a Linux box as a NAT router on my home network (machine name marvin).

Hello all, Can anyone recommend a good book which thoroughly explains QoS from a Linux perspective? Something with TC examples & the like. I''ve looked at the following: http://www.amazon.com/gp/product/1580533418/qid=1148368189/sr=1-2/ref=sr_1_2/102-2819973-6353768?s=books&v=glance&n=283155 Engineering Internet QoS. Thanks.

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

I wrote a Perl script to poll `tc` for traffic control statistics (just bytes presently) for leaf qdiscs. The information is fed to either RRDTool or Munin[2], depending on what parameter is passed to the script. If the option for a RRD database is used, graphs[3][4] are written to disk for each ten second polling interval. If invoked via Munin[2], it handles graphing and samples at five

Hi, Can anybody help me out, how to manage or limit bandwidth through iptables while having internet connection on eth0 and working as a gateway in LAN. Thnaks in Advance.

Hi, I wished to shape the traffic that cross my ppp0 interface so I asked around and google''d a bit and I headed in the LARTC HOWTO. As stated in the early in the text, as the title implies, that is an "Advanced" HOWTO and while by no means rocket science, some prior knowledge is assumed. Unfortunately I found myself lost very soon and I''m writing here in hope

Hi, We have a 256 kbits/s (kilobits per second) link to the internet. it is a router running Linux that belongs to our ISP. They have given us 8 internet ips. (i.e- subnet is 255.255.255.248). one has been given to this router. I have given another internet ip to the firewall running CentOS 4.5. iptables is running on it. And also, I have installed iproute2 pkg as well. pls see below for

Hi all, I''ve not been able to find an explanation of the relationship between prio and rate as they apply to the HTB technique. Hopefully someone on here will be able to help me. As I understand things, when prio values are assigned to an HTB setup, classes with a given prio value will only be serviced when there are no packets waiting in classes with a lower prio value. Now, does

Hi. I''m trying to get a traffic shaper like this: ------ VoIP pkts --> | |_| ------ \ | ---O -> ------ / Data pkts --> | ------ In this shaper voip packets are in a different queue than any other kind of packet. I want a data packet to be

As you are probably aware, this is a ever green topic. I have personally tried doing it, testing it and verifying it and I am myself finding this problem challenging and frustrating. Most of the scripts will recommend some form of rate limiting ( or policing ) on the download. But the challenge is how to determine the correct value for the policing ? Lot of the recommendation says use x %

Hi I''ve patched net-mrtg http://www.net-snmp.org/ with http://x-ray.prokon.cz/data/snmp/ sucefully Also I''ve copied QOS.TXT to /usr/local/share/snmp/mibs when I make a normal use of snmp, with mrtg in order to monitor all traffic on eth0 and eth1, it works OK. But, how must I do in order to get monitor for a specific class ? If I make a snmpwalk (like README suggest), I get

I had been using L7-Filter[1] successfully for edonkey/eMule traffic until recently. I upgraded to the latest release of mldonkey, 2.5.28a, which implements eMule compatibility, and with support for Kademlia[2] enabled, network latency increases greatly.

Hello, I setup iproute2 and iptables on my box, is a P4 2000 Ghz / 1GB memory. I have setup squid and iptables to be a transparent proxy, with cache. I''ve read on lartc.org almost everything and i want to ask if there is a u32 match for the connection time or something like that, or an u32 match for the packet number in a connection. All i want to do is shape the web traffic for long

Hi all, After a long reading of the LARTC, I were able to set up a working HTB config on my firewall. But my question is : Can I use a "ip less" box to do QoS ? With bridging software (or even without?) or thing like this and use an u32 filter to direct the traffic to the right class ? In other words, I can''t modify the existing network config or inster into (netmask is

Hi All, I wonder can I do NAT+mangle+tc on same maschine? I want to shape outgoing traffic per IP on my gateway computer.

Hello, I''m trying to configure several wireless routers with QoS support. The idea is to implement differentiated services so that VoIP traffic gets the maximal priority, then video, control traffic, interactive data traffic and best-effort traffic. I have seen that CBQ used to be chosen as qdisc for implementing bandwith share in DiffServ but now HTB is preferred because it is
