similar to: TOS filed and pfifo_fast

Hi, I have a cable modem with a bandwidth capped upload rate. I''d like to prioritize packets going outbound according to the TOS header of the IP field. I''ve read through the LARTC Howto several times, and I think I have a good feel for the information it it. It also seems that what I''m trying to do is pretty straight-forward and common. Unfortunately, the HOWTO

Thank you Andy! I did''t find why I could''t use the fw match in ingress. Now it works. Now I ran into another problem: When I try to add a pfifo_fast leaf qdisc dor htb classes it seg.-faults. Is pfifo_fast a special qdisc? I can succesfully add other type of qdiscs. I found that a similar problem was reported in february on a MIPS architecture. root@zefir:/usr/src# tc qdisc

Hi, I have following queries: - 1.How to see data exchanged at all the bands of pfifo_fast(command)? "tc -s qdisc ls dev eth0" only shows following output qdisc pfifo_fast 0: bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 Sent 71132584 bytes 312294 pkts (dropped 0, overlimits 0 requeues 0) Its only showing data exchanged in band 0. 2.I am using following command to drop

Hello, I use HTB on IMQ, and I would like to use pfifo_fast on my HTB leafs. Do I need to add a pfifo_fast qdisc to my HTB class, or this is the default one? I tryed to add and I got: RTNETLINK answers: Invalid argument It looks like pfifo_fast qdisc is not supported on HTB leaf... Any comments? Regards, Thomas _______________________________________________ LARTC mailing list /

The HOWTO mentions 3 seperate bands for the simple pfifo_fast queue, how do I need to specify which band each packet needs to be in? Do I only need to set the correct TOS field or is there anything else I should do? Thanks. Tung

Dear All, I’m working with Fedora Core 3, kernel 2.9.1, MPLS-for-Linux-4.193, and having some problems when create a HTB queue. ALL packets goes to the default queue, they don’t care about any mark or ip field I use to enqueue them. : -/ That’s the deal, all packets that incoming the interface eth2 are classified and have theirs TOS field changed following some qos policy at the PREROUTING

Hi list, I have a quick question about the priority mapping of tos bits. The manpage of tc-prio shows a nice table with tos bits and the band they are mapped to: TOS Bits Means Linux Priority Band ------------------------------------------------------------ 0x0 0 Normal Service 0 Best Effort 1 0x2 1 Minimize Monetary Cost 1 Filler

Hello I am trying to attach pfifo_fast to af leaf htb class. But tc segmenetation faults. If I try the failing command throug strace, it shows me that the last thing tc tries to do just before the segmentation fault, is to try to open a file called "/usr/lib/tc/q_pfifo_fast.so". Of course i have tried to find worthfull information around the Internet, but haven''t found

i am trying to do some traffic classification using the PRIO qdisc and i am having a few problems. I have a root htb class: tc qdisc add dev imq0 root handle 1: htb default 255 r2q 1 tc class add dev imq0 parent 1: classid 1:1 htb rate 768kbit and a child PRIO tc class add dev imq0 parent 1:1 classid 1:99 htb rate 96kbit ceil 600kbit prio 0 tc qdisc add dev imq0 parent 1:99 prio tc filter

Hello lartc maintainers and users! I have a router with two NICs. One NIC is connected to the Internet and the other to my internal LAN. I made a script for priorizing interactive traffic. The script matches TOS Minimize-Delay for priorizing interactive trafic, and fwmark for metropolitan packets. I have two root classes (simulating two circuits) : 1:1 for internet and 1:3 for metropolitan.

Hi, After reading section 9 of LARTC it seemed to me that a pure TOS based QoS setup with be sufficient for a small newtork. Interactive packets could have the highest priority, second highest for DNS and small HTTP packets and lowest prio for all others. The advantage is that, the setup would be simply a couple of iptables lines, because the default pfifo_fast qdisc already implements

Hi everyone. I am so baffled by the following problem: Office 1 is using ADSL and it is building a VPN tunnel with IPSEC to Office 2. Both ends are using shorewall/freeswan firewalls.

My dcgui-qt (chat/file-sharing program) doesn''t work and I''m pretty sure it''s my firewall settings. dcgui-qt is a direct connect (file sharing & chat) client. According to the FAQ here (http://dcplusplus.sourceforge.net/faq/faq.php) all I should need to do is: ------- #ACTION SOURCE DEST PROTO DEST SOURCE ORIGINAL #

Hello everybody. I could not find an answer to my problem in the archive. (But that may just be me :-) ) I have a problem with proxy arp and connection from loc (localnet) and from the firewall. Works fine from internet to dmz / proxy arp and vise versa. I have a feeling the solution is simple, but I''m no guru in Linux routing etc. The problem seems to be the routing setup. loc -

Hi! I was updated kernel from 2.4.22 to 2.4.23 and now tc tools can''t correctly determine default (pfifo_fast) qdisc on interface: # tc/tc qdisc ls dev ppp0 qdisc pfifo_fast 0: [Unknown qdisc, optlen=20] but, if I assign f.e. cbq qdisc for some device all show correctly: # tc/tc qdisc ls dev ppp1 qdisc tbf 8009: rate 32Kbit burst 10Kb lat 1.5s qdisc cbq 66: rate 10Mbit

I have a machine running 2.4.25 w/ wrr, ebtables-brnf, iptables CLASSIFY and esfq patches (not using esfq, though). I have wrr set up, and within each class I want to prioritize ssh, web, etc..., but right now I am testing with pings. I have the following in my POSTROUTING mangle table: CLASSIFY icmp -- anywhere anywhere CLASSIFY set 0:6 I find that if I attach a prio

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

I must have something configured wrong somewhere. I''ve enabled proxy-arp on my shorewall 2.0.7 firewall. Works fine for what its supposed to do, I can see all the machines through it great. However, whenever its enabled, the network on the DMZ goes screwy. I''ve narrowed it down to this: when proxy arp is enabled for that interface, like such: echo 1 >
