Hi all, Does anybody know a package to control the bandwidth using "TCP Congestion Control" method? Best Regards Hoomaan Naimi Afranet Network Administrator

I presently use TBF with this syntax: tc qdisc add dev eth0 parent 1:100 tbf buffer=15000/8 LIMIT=30000 MTU=1500 parent class is a cbq with rate=128Kbit when I want to add PEAK, I get always RTNETLINK error: Invalid argument. Maybe be I don''t understand this parameter. What I know about it, it''s that it can control short-term burst traffic, and it''s what I need to do.

Hi, I am writing a kernel module which works with netfilter. If a certain condition matches, I want to create a qdisc, a class and a filter inside the kernel module. How can I create qdisc, class, and filter inside the kernel?

Hi, in FreeBSD kernel is options that make router stealth, packet passed throw router have no change in TTL value. Is a posibility to make similar thing in Linux, I think that in traceroute isn''t this hop, no asteris, no router, no change in TTL, nothing ...? PSIkappa psi@atlantis.sk

Hello, it seems, that filtering on nexthdr (TCP/UDP) content, especially src or dst port, is not working. The following has no effect on 2.4.16 or older (even 2.2) kernels: # tc filter add dev eth0 parent ffff: protocol ip prio 50 u32 match tcp dst 3128 0xffff police rate 40kbit burst 10k drop flowid :1 Even if # tc filter ls dev eth0 parent ffff: filter protocol ip pref 50 u32 filter protocol

Hi there, I have two ethernet connections of 2Mbit/s each and I''m trying to add them together to one 4Mbit/s connection but I cannot get more than approximate 1Mbit/s! My setup: I have a LAN (10.2.18.0/24), connected to a larger network (10.0.0.0/8) by two WAN-connections with 2Mbit/s each. On each end I have a Linux router. I first setup the routers to use TEQL with one of the

Hi, I would like to control download bandwidth from the Internet for clients inside a network. The gateway is a Linux box using ''iptables nat''. I would like to use ''iptables mangle'' to mark the packets coming from the Internet and going to specific clients and then use CBQ to shape it: +-----------+ Internal network | Linux

I find the negative attitude toward CBQ to be distracting and non-professional in the HOWTO. I''ve re-read it for the first time in about a month and comments like "This can be configured in a variety of ways, which I do not understand. Use HTB" do not encourage me about the writer. This is not a personal critique, as I can imagine this being said on a personal website,

I''m a newbie to tc and after some experimenting I have the following problem: # tc qdisc show qdisc sfq 8006: dev ipsec0 quantum 1514b perturb 15sec I can''t get rid of this entry. Is there a way to clear all entries? I tried all sorts of "tc qdisc del xxx" but nothing seems to work. It says: RTNETLINK answers: No such file or directory What syntax do I need to

Hi, I am developing on an embedded MIPS-based system; I have iproute2''s ip working correctly talking to the kernel, but tc seems to be broken. I''d like to fix this, but I need a little bit of help in figuring out how tc communictes with the kernel -- can someone tell me the places I should be looking? Thanks. Joseph

Hi all, Has anyone experienced QoS over an ISDN connection? Have you found any trouble setting this ? In fact, I hasn''t to exist any trouble but not in my case. I have tried something and it seems doesn''t work every time. Besides, I need more tests. But for the moment, any experience information will be useful. Thanks all in advance. Esteve Camps

Some (non urgent) questions about "tc" parameters: What is "weight" for? We''ve seen that leaving it out of our script causes error/warnings like: CQB: class 00010012 had bad quantum==0, repaired. Which values should it have and why? When should one use the "split" and "defmap" parameters? I guess they can be used to specify the best effort

Greetings The ip route how-to describes the following for setting up source routing #echo 501 uras.out >> /etc/iproute2/rt_table #ip rule add from 10.0.0.0/24 table uras.out The first line complains of a missing directory, which is simple fixed (create dir iproute2 in etc) The second line then reports Error: argument "uras.out" is wrong: invalid table ID The op sys is RH 7.

You guys are my last resort... When i do ip rule add/ls/del i get this message: RTNETLINK answers: Invalid argument I use 2.4.0 kernel with ip:adv. route, and pol. routing compiled in.

Hi All, As it is written in the "Linux 2.4 Advanced Routing HOWTO" GRE tunneling has some benefits compare to IP-in-IP, on of it benefits is the ability to transport multicast traffic through a GRE tunnel. I used the mrouted daemon and I know that the daemon supports tunneling but I don''t want to use its tunneling method. Assuming I have gre0 as my tunneling device I did the

I''d like to make a suggestion to the Advanced Routing HOWTO. I have read parts of it some months ago and I had a hard time following it and I think that I know the reason: the HOWTO doesn''t give the background on the subjects it discusses. This difficulty was particularly evident when I was reading the part about Quality of Service/Bandwidth Shaping. I got the impression

Hello, I''m working on the french tanslation of the howto and i''m asking some questions about the chapter pseudo-bridge / Implementing it Here the list of that we need to do : 1.Assign an IP address to both interfaces, the ''left'' and the ''right'' one Is it the address on the differents interfaces ? Or is it two different address of the same
