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

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:

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

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

OK, here it is. Near perfect bandwidth calculation for ADSL users. Patch iproute2 with the HTB stuff and then this: It''s still a hack (as far as I can tell) because we are patching the rates tables, and hence I think it is only loosly coupled with the actual calculation of bytes in each bucket. However, it works very nicely for me! I have only been lightly testing with

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:

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

GlusterFs always strikes me as being "the solution" (one day...). It's had a lot of growing pains, but there have been a few on the list had success using it already. Given some time has gone by since I last asked - has anyone got any more recent experience with it and how has it worked out with particular emphasis on Dovecot maildir storage? How has version 3 worked out for

Hi, more than a month ago I proposed an addition to the HOWTO to address a certain packet classification problem/bug and how to fix it (see http://mailman.ds9a.nl/pipermail/lartc/2005q3/016728.html). I never received any reaction from the HOWTO maintainers, not even when addressing them directly (see mail below). Given that a month has gone by: Is the HOWTO currently unmaintained? Regards,

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

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

I''ve been lurking for a while, trying to figure out this traffic control stuff. We have 3 ADSL modems upstream, with 2, 2, and 1 megabit total bandwidth, 1/4 of it up, 3/4 down. We also have about 200 workstations downstream, connected through wifi. We are presently using tc to create about 200 buckets with HTB and SFQ. It seems like this is too many buckets, since usually only about

Does anyone have any pointers on how other people have implemented tcp window adjustment to do bandwidth shaping? Granted the basic idea is to set the window size to be RTT * bandwidth, but a quick squiz at google turns up mostly papers on how to implement this at the sender end with a view to some new magic TCP implementation. I''m really interested in notes on how to implement at

Hey there everyone, I appreciated everyone''s help so much in the last few posts I decided to post some more! :) We implemented our bandwidth management machine on the network last week and everything looked great. After looking at it today, anything past the machine is losing major packets and the latency is high. I''m using RedHat 9.0 on a Pentium 4 2.8ghz with 512mb of ram.

Is there a clever rails way to chain multiple forms together to collect all the info that I need before finally calling "save"? For example consider an app which needs to create a "Order" object which is tied to a "Contact" object which may or may already exist. Lets pretend we don''t want to save the order to the DB until the contact info is known and

Hi I have the following problem: I''ve created qos script which shapes traffic on outgoing interface eth1. More - less it looks like this : ------------------------CUT------------------------------------------------------ #root qdisc and class for eth1 $tc qdisc add dev eth1 root handle 1:0 htb default 19 $tc class add dev eth1 parent 1:0 classid 1:1 htp ratel ${CEIL_UP}kbit ceil

Hi all, ive got 2 internet connections set up via the nano howto (which are working great) and we are running NAT. Was looking in to qos mainly to stop large http downloads/ftp downloads from hogging the line so that browsing for other users doesnt slow to a crawl, but if the line is free and no one is doing anything then for it to use the available bandwith. The wondershaper sounded exactly what

Can I ask for some advice on dial-plan construction please I have setup my dialplan to use 9 to get a zap trunk, leaving everything else for internal extensions. However, this creates a problem in that my callerid is correct, but doesn't work to re-dial the incoming caller. So if I simply click "missed calls" on my Snom phone and hit redial then it tries to dial an internal
