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

Hi routing-experts ! If I want to prioritize up ssh and telnet traffic with Linux 2.4 netfilter and iproute2. I''ve set outbound tcp 22, 23 and 21 TOSbits to minimize delay, but this doesn''t seem to be enough to prioritize ssh over for example http-traffic. I''m using modem to connect to Internet and got an entire LAN behind the Linux router/firewall. Well, I think most

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, 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

From: Matt Fleming <matt.fleming at linux.intel.com> This series includes a patch (PATCH 1/6) that I sent previously but I thought it was worth sending it again since the rest of the series depends on it, and it also gives a bit of context. These cleanups make it simpler to do the big switchover to ELF modules on the elflink branch because the libraries in $LIBS are now contained in one

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,

Dear R users: I have a problem about catch the value from function. I have following two functions (part): fbolus1 <- function() {......... par<-data.frame(Parameter=c("kel","Vd"),Initial=c(0)) check(par) .....} check<-function(par) { if (par[ ,2] <= 0){ cat("\nEnter again (y/n) ?\n\n") ans<-readline() if (ans == "n" ){

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

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.

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

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

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

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

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

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.

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
