Hi Guys, I have a couple of problems that are driving me nuts. This is the script I am using to setup restirctions and bw limitations: #Adding root class. tc qdisc add dev eth0 root handle 1: htb default 10 &>/dev/null tc class add dev eth0 parent 1: classid 1:1 htb rate 100Mbit ceil 100Mbit burst 2k quantum 1536 tc qdisc add dev eth1 root handle 1: htb default 10 &>/dev/null tc

Hi, all I am interested in Linux related QoS, especially PRIO queue discipline (qdisc). I test some experiments about PRIO qdisc. Host A ------ Router A --- Router B --- Host C | 1Gbps | Host B ---------+ +-------- Host D flow 1 : Host A -> Host C (TCP) flow 2 : Host B -> Host D (UDP) priority 1 queue (pfifo, size 1000 packets ) : flow 1 priority 2

hello folks, this is my first post to that list. so I hope I am not completely OT here :-) reading the (excellent!) lartc and then writing my own qos-script I have still some open questions which I will try to formulate now: - "Now we can optionally attach queuing disciplines to the leaf classes. If none is specified the default is pfifo." - I can''t find info about Pfifo.

Hello. I''m running linux box with Slackware 9.1 and compiled kernel 2.4.31 with "yes" to VLANs and "yes" to all QoS. On this box i have more ethernet interfaces: eth0 eth1 eth2 and so as more vlan interfaces: eth0.100 eth1.3 eth1.4 This is entrace(uplink) router to our whole network and my goal is to shape users on this machine. I want for this purpose use HTB so

Hi all, Long email but please be patient :) I am part of EHAS [1], a non profit organization which main goal is to improve the Healthcare assistance in isolated rural areas in developing countries. Recently we have developed a long distance Wi-Fi network in Cuzco (Peru). This network provides connectivity to 12 nodes (they are in fact Health Centers). As VoIP is a essential service in this

Hi. I did send this to `jaazz@post.cz'', but I suspect the list is a more appropriate/useful place for it. It''s a question about Michal Charvat''s QoS extension to Net-SNMP. When I look at the MIB entries for the QoS handles, I get something like this - enterprises.qos.qosObjectTable.qosObject.qosHandle.0.0 = Gauge32: 0

hi below is sysvinit script for handling tcng-script .... please excuse my bad bash skils, correct me where i''m doing stupid things :") what is left... many things, if i have time i will implement them too : - start [devices] - and then correct handling of service lock files i.e. per device lock file - stats blah ... - all ideas are welcome !! - test or some such, i mean the

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

Hello all, I might make a fool out of me, but I think the prio qdisc doesn''t work as advertised in any document I could lay my hands on. The following tests and observations were made with Linux kernel 2.6.20.21. This makes it up-to-date in the 2.6.20.x kernel family. My problem was that the link quality reported by the olsr.org olsrd degraded depending on the amount of payload

I''m trying to configure 4 queues with strict priorities based on DSCP. I tried to following commands, but it seems that the filters I defined have no effect tc qdisc add dev eth0 root handle 1: prio bands 4 tc qdisc add dev eth0 parent 1:0 handle 10: pfifo limit 100 tc qdisc add dev eth0 parent 1:1 handle 20: pfifo limit 100 tc qdisc add dev eth0 parent 1:2 handle 30: pfifo limit 100 tc

Hi i want see if my QoS are good because i am not very sure ... the VoIP quality are not very good when i download. I have on my Linux routeur/Firewall Asterisk .. and i have into my config : ================================================ tcdevices: eth0 2000kbit 2000kbit tcclasses: eth0 1 100kbit 180kbit 1 tos=0x68/0xfc,tos=0xb8/0xfc eth0 2 full/4 full

Hi all. I''ve written a small htb script that uses U32 and FW (marked by IPTABLES) filters, but TC doesn''t seem to be using the "cls_fw.o" module !!! I''m using redhat v9.0, kernel 2.4.8-20, iproute 2.4.7-7. Here is my script: ========================================================== ##################### #Interface definition #####################

Greetings - I''m new to QoS, so please be gentle (and yes, I''ve RTFM, though I don''t understand every bit of it) Here''s the thing; I''ve tried several scripts--simple and complex--for classifying my Vonage traffic into a high-priority queue, but no matter what I do it doesn''t seem to work. Right now I''m using the HTB script

I shape my upstream cable link with HTB from a script. My voip traffic (from the 192.168.0.14 host) gets priority over everything else to the near-starvation of other classes; the rest of the traffic is split up based on some priority rules (qos, empty ack packets, etc). eth1 is the uplink I''ve been using HTB and fw marking for the job until recently, when I changed the queue structure

Hello. In short Linux Advanced Routing & Traffic Control HOWTO''s chapter 15.4. Prioritizing interactive traffic does not help me at all. I have an asymmetric ADSL connection nominal 64Kbit in / 16Kbit out, real (based on bulk transfers measures) 256Kbit/26Kbit. First thing I would like to improve is to keep interactive (ssh) connection fast even if uplink is full. The test I make

Help me  ... I try use the tc filter, but seems he doesn''t work, I already reconfigured my kernel ( 2.4.32 ) with all options related a QOS enabled ( like modules ) and nothing happens. I get the tc tool from HTB source package, well  this is my set : eth0 is my internal NIC. tc qdisc add dev eth0 root handle 1: htb default 12 tc class add dev eth0 parent 1: classid 1:1 htb rate

i have a customer that needs to plug the phones into the pc's using the pass-through rj45 available on most sip phones the question they are asking me is how to keep the data network separate from / secure from the voip network i understand they can set up vlans but i am hazy on a few details 1 since the phones are plugged into the pc's how will the phones be segmented into their own

A site I administer has dual T1''s. We have this set up according to NANO-HOWTO[1] using Julian''s routes patch on a late model 2.4 kernel. All is well, has been working well for a long time. Recently one of our T1 providers went belly up and we got something better. Now we have a /28 where previously we only used one IP per interface. Present interfaces: eth0 - T1#1, single
