similar to: patch: HTB update for ADSL users

Hi everyone. I''m new to this list and I have some questions regarding HTB class. I was trying to see how tc sets the parameters for HTB, but really couldnt understand them. So, I thought that I might ask the wizards. It''s mainly from the source code. 1. What is the cell_log ? (its everywhere in the code) 2. Why does htb calculate its burst(buffer) with tc_xmit_time() ? Is

Hi. I wrote in a reply to a mail on here recently that you can''t set mpu (minimum packet unit) on HTB as you can on CBQ. I''ve just noticed that there is a patch on devik''s site which does mpu and overhead. http://luxik.cdi.cz/~devik/qos/htb/ For dsl users mpu is, for practical purposes going to be 106 - overhead is still variable though, depending on packet size.

I have been trying to optimise my ADSL connections for VOIP. Funny things were happening - for example increasing the ping packet size by 50% had no effect, but then adding one byte had a major effect. It took me a while to figure out that I was seeing the effects of the fixed ATM cell size. This is probably obvious to some of you. For the rest: ADSL uses ATM as its transport. An ATM

Did anyone see the article? It''s the first time I really noticed that these little Linksys routers are such a fully fledged linux machine with a decent processor and a replacable firmware. I am now itching to get one to replace the multipurpose firewall desktop machine. Has anyone experimented with the current state of the firmware and how advanced you can get with tc rules? For

Hi I want to block the IP traffic between any 2 hosts on a switched ethernet LAN. Will setting all the possible IP addresses on a linux machine in the LAN do the trick or there is another easier solution? -- Anton Glinkov network administrator _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO:

Hi, I''ve written a small javascript ADSL throughput calculator: http://nukunuku.yamamaya.is-a-geek.org/~ranma/adsl.html Feel free to submit alternative presets (I currently have presets for three german telecom speed variants: T-DSL (1000|2000|3000), derived from http://www2.lancom.de/kb.nsf/5d445c701b3ff52dc1256e7700297e5c/27c6ee1c3e3f74b0c1256e94004a433e?OpenDocument).

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I''m using HTB to shape my outgoing traffic over a ADSL-link with PPPoE with a nominal bandwidth of 128kbit/s. My goal is to favour small packets like ACKs and interactive services like ssh; in other words, I want to achieve low lantency. If there are some big packets going over the wire, everything works fine. But if there are

Well I got mine from http://ftp.iasi.roedu.net/mirrors/ftp.inr.ac.ru/ip-routing/ but I didn''t even know about those 2.6 ones... I''m using the latest 2.4.7 with my 2.6.5

I''m playing with the rather excellent QOS script from Alexander Clouter at http://digriz.org.uk/jdg-qos-script/ So far I am really impressed with it - a very impressive example of the power of linux QOS rules (has pretty much everything in it from the LARTC Howto!) However, the instructions hint that "for QoS to affect locally generated traffic in a non ethernet bridge setup

Hi I have to manage a network with approx. 200 users, a 256kbit/s unmanaged Internet connection and a 3Mbit/s unreliable managed Internet connection (only http/ftp-proxy and ssh available). All users are in one Class C Subnet with 512 IP-Addresses. 60% of the machines are Windows. The rest are SUN and Linux. At the moment Windows viruses and p2p-traffic eats most of our bandwidth. My Aims are:

Hey guys, I have several Linux routers in place at high-usage locations (student apartment complexes). I''m having trouble with some of the routers which use 6Mbit DSL lines as their Internet feed. The routers use PPPoE and perform NAT. During peak usage periods, the routers are dropping alot of packets. I''m lead to believe this is because there are too many active

I have a requirement which I guess it is not too unusually, however I haven''t quite figured out how to do it and couldn''t find any examples which handle that. I have made myself a Linux-based bridge, eth0 bridged with eth1 to form br0. In this bridge, I run ''tc'' script to handle QoS. So far nothing unusual. However, what''s different is that this

I''ve got a linux router pushing 600-1000 pppoe connections through it. I''m getting a screen error "Neighbor Table Overflow" after this box has been up for between 1 week and 1 month. When this is happening, routing slows to a crawl if at all. Then dies. I''ve added: # Added to stop "neighbor table overflow" messages in the kernel

It seems Andreas Klauer''s fairnat has experimental support for using HTB''s MPU and overhead options. fairnat.config: # Use MPU for HTB. From the LARTC Howto on MPU: # "A zero-sized packet does not use zero bandwidth. For ethernet, no packet # uses less than 64 bytes. The Minimum Packet Unit determines the minimal # token usage for a packet." HTB_MPU=0 # HTB_MPU=64

Hi, I''m trying to build an ipsec gateway and somewhere I''m doing something wrong. I have a couple of routers that have clients in their back. All the routers are connected into a switch. In that switch I also have a computer that provides internet access to the clients. I would like to setup some sort of autentification (don''t need encryption), to allow me

I have a Cable ''modem'' that has a problem that many of these devices is bound to have. I was wondering what other lartc user thought about this and if DSL has simular problems. Cable, being Asymetrical, is able to upload at a given rate and hopefully has a buffer, in the modem, of some kind. When I nc(netcat) to a UDP echo, or discard, server I get about 10Mbps out on my

Hello there! Yesterday I started my experiments with HTB. I configured it this way: 1: root HTB qdisc | 1:1 HTB class rate 1000kbit | /-------+------\ 1:40 1:50 1:60 user1 user2 user3 rate 333 & ceil 1000 for everyone. User2 is disconnected and user1 and user3 are downloading. For all the time (t1-t5) there are ONLY these two users downloading! HTB should give

Guys After reading through the archives I found some insightful ways to be able to shape traffic to pppoe clients from the server. I have two questions on the topic of setting up a pppoe server however... 1. The clients will all be connected to each other using a normal ethernet network, the segments connected with managed switches. The capacity is roughly 500 nodes. Will these pppoe sessions

I have three ADSL lines that I''d like to use as one big pipe to the internet. The ADSL service works by establishing a pppoe connection (the ADSL "modem" is a bridge), and each pppoe interface gets its own IP address. This means I''d have to have 4 ethernet interfaces (3 for each of the ADSL modems and 1 for the LAN) in my gateway. I''d setup the gateway to NAT

Hello everyone, I hope this is on-topic for the list... I''m familiar with NAT, but I can''t see how to route a fully routed LAN. My new ISP has given me a /29 (I understand this to be 6 addresses + network address + broadcast address) which I would like to use, as multiple PCs here want to use p2p and games at the same time, and reconfiguring the port forwarding all the time
