similar to: tc troubles with pfifo_fast qdisc on 2.4.23 kernel

Hi all, I''ve done a search through the archives but I can''t find a cause/solution to this. I''m running a FC4 box with the stock 2.6.12 kernel and a FC2 box with a stock 2.6.9 kernel. I''m obviously using iproute2 and the patched tc. When I clear down the qdiscs with "tc qdisc del dev <DEV> root" I get the following in response to "tc

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

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

Hello, I am trying to revive an old linux server installation, which still has libc5. Sadly, most current software does not compile anymore on this system, including the tc utility. As with other tools (net-tools, coreutils, procps etc.) I tried to compile and statically link (LDFLAGS=-static) on a more recent linux machine and copy the static binaries over to the old machine. But no luck

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?

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

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

I would like to use HTB''s prio parameter as the sole priority value for pfifo_fast. Is the TOS field in packets honored by an HTB class with the default pfifo_fast qdisc enqueued when coming from a child class with a prio parameter?! If yes, what''s the least expensive way (in terms of CPU cycles) of stripping all packets from the TOS field?!

Hello, I read about the pfifo_fast has 3 bands, which allow you to prioritize traffic into these bands. I cannot find anything about these bands in the tc command reference (http://linux.bergqvist.se/tc/). I might be looking the wrong place - in which case, where should I look for help with this qdisc? The idea is to give "time-critical" sessions such as ssh, telnet etc. HIGHEST

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

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

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

please, help, i have build vpn server (suse 9 + poptop), i have managed to implement tc htb in ip-up script, but every client has own ppp interface (ppp0, ppp1, ppp2...), and my idea is to share available bandwidth, not to limit connection, how to build root tc rule, when I have more then one interface?... please any one width experiance regards _______________________________________________

Hi there, I have two questions: 1) In the following setup: tc qdisc add dev eth1 root handle 1: htb tc class add dev eth1 parent 1: classid 1:1 htb rate 100Mbit tc class add dev eth1 parent 1:1 classid 1:10 htb rate 128Kbit tc class add dev eth1 parent 1:10 classid 1:11 htb rate 32Kbit ceil 128Kbit tc class add dev eth1 parent 1:10 classid 1:12 htb rate 32Kbit ceil 128Kbit I have observed

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

The command i''m running is: tc qdisc replace dev ppp0 parent 8001:D handle D: tbf rate 5Kbit burst 5kb latency 70ms The idea being to replace an sfq with handle D and hopefully limit a certain user in my

hi, i am currently working on a project on "design of diffserv testbed in linux". i am using tc utility of iproute2 for it. The qdisc dsmark used for marking the DS codepoint at the first hop router makes number of classes depending on the indices given in the command. But i am not clear how at the first hop router does scheduling takes place. what i mean is if i have two flows, whose
