similar to: Strange QoS behavior

Hi, I'm having some weird problem with the setup of the QoS on a bridged network. As the docs states, outbound/inbound average speed should be expressed in KBps (KBytes per second) but in order to get a maximum speed of 10Mbps (megabits per second) surprising enough I have to use 2560 on the guest (not 1280 as expected). Using 1280 units I get a speed og 5Mbps. I'm aware of peak and

I have been given a set of "firewall rules" to open my firewall for DCC to support my spam filtering. (I have done many web searches trying to find info relating to DCC with Shorewall, to no avail. The problem is that I am clueless on how these "rules" translate into the shorewall rule format. Could someone please help me translate these? allow udp local gt 1023 to remote

Hi, I set up DCC on CentOS 5 with Dual Sendmail - Amavisd-new and and Spam assassin. I installed DCC from AT rpms. pls see below for installed DCC rpm. [root at mailgw ~]# rpm -qa |grep DCC DCC-1.3.50-16.0.el5 Then, I configured in Deamon mode. I did below steps. [root at mailgw ~]# yum install DCC then, [root at mailgw ~]# cdcc "delete 127.0.0.1" [root at mailgw ~]# cdcc

Hi everyone, For ssh(1) to override global options with the options in "Host" block, the attached diff (w.r.t. the openssh code in FreeBSD 8.1-R) contains the code to do so while parsing ssh configuration file. This is useful for case like following where {d,proj,p,n}cvs.FreeBSD.org is an alias to ncvs.FreeBSD.org hostname, thus connecting to {d,proj,p,n}cvs.FreeBSD.org should utilize

I have currently following the instructions at- http://www.voip-info.org/wiki/view/QoS+Cisco I am using a Cisco 877 router with an ADSL2+ connection. My upstream bandwidth is around 1Mbps, and my downstream around 4-5Mbps. I have two PSTN side interfaces - atm0 and dialer0 (dialer0 is where the ISP details are configured and the interface that the WAN side IP is applied on) Now which

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

Hi, Distribution: openSUSE 42.2 Beta, Kernel: 4.4. The box is a Dell Precision T7500 with an nVidia Quadro 4000 card and a displayport connected iiyama B2783QSU 2560x1440 monitor identified as DP-1. Problem: The monitor is detected as 1920x1080 and not 2560x1440. See Xorg log file at http://rogerprice.org/Xorg.0.log . There is no file /etc/X11/xorg.conf and in the directory

Hello First thanks for the answers I have received from the list!! I have now a working qos configuration which bases of the lartc howto capitel 15.10. One Problem I have is that I have limited the upload stream to 100kps because my upstream is only 128kbps. Everything works fine EXCEPT Voip. I have a VoiP phone which is connected on the same net as the adsl modem BUT does not use upstream it

Hi, I''ve got 3 questions: 1) is it possible to do QoS and OpenVPN? I thought about doing QoS based on IP, as there''s a couple of servers here that need to be on a higher priority. 2) can anyone point me to a decent QoS how-to? 3) damn, I can''t remember what this one was. :o) Cheers, Fernando

I''m using KOM_RSVP I''m trying to figure out what trigures and RSVP session. When I send traffic with a certain utility the RSVP PATH, RESV, and CONF message is sent. How does the Deameon know to setup a connection though? There is something internal at the client source happening. I just haven''t figured it out yet. Is it listening to a certain port? Any help would

Hi all, I have been tasked with "implementing QoS" on one of our networks. Looking at the documents of LARTC I believe I can implement most of what we want just using netfilter rules and tc. So far, so good. My question though is how can I analyse how much of an improvement I can expect to achieve using these kinds of solutions. Does anyone here have any experiences that they can share

Hy, I''ve two question about the QoS on a Linux system. 1) What''s unit it uses for the rate in the differente configuration of the schedulers, IP rate or Ethernet rate ? 2) Is it possible to attach on a interface, a queues with a strict priority scheduler and two or mores with a HTB scheduler ? For example, a queue for the VoIP with a strict priority, 2 queues for Video and

All: I am tasked with creating an environment in which DiffServ and IP precedence is handled as close to RFC specification as possible. I have a few problems with implementing this based on current queueing structure. Here are a few of my questions. 1.) Is there any way to get DiffServ AF drop levels without using DSMARK and GRED? Ex. AF11 Gred DP 1 AF12 Gred DP 2 AF13 Gred DP 3 2.)

Is there anyway to actually see packet stats or that packets are for sure going into a prio queue with TC? I can see all the HTB stats but the prio classes just list as being there...would like more information Basically I have the following setup DSMARK | HTB - (tcindex filter on TOS) | Prio (u32 filter on TOS) Thanks Jon Flechsenhaar Boeing WNW Team Network Services

Hello, I''ve setuped a QoS bridge under debian. I would like to know If anyone have got some ressources about how setup perfectly VoIP (SIP/RTP) QoS with Asterisk Might be I should use TOS ? Regards

Hi, I''m trying to figure out how to use Linux QoS. Default setting has three queues (bands) and should prioretise outgoing tarffic based on TOS field. I try to test that by flooding Ethernet interface by netperf or iptraf and running ping -f with -Q and without Q. -Q doesn''t affect ping results, it suffers anyway. It seems that I don''t understand something. I verified

Hy, I would want to give QoS a one wireless network. Do you know if exist any qdisc specific for this??. I know that the most modern qdisc is HFSC, is this true??.
