similar to: Interleave cells with IP over ATM?

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

Hi, I am writing this email in sincere hope that somebody experienced similar/same problem and found solution to it. The classical bridge setup could be achieved using brctl tool, which could be found at: http://home.regit.org/br2684.html I have an ADSL CO line card Linux based [2.4.24 kernel] with 8 nas interfaces and eth0. Rather than having bridge, the decision was to have a router, which

Hi I''m using wondershaper like script. But noticed imperfect scheduling. By googling, I found some patches that takes the aal5 atm overhead in the scheduling algorithms. http://www.adsl-optimizer.dk/ADSL-optimizer/ Before trying it, has anyone tried these patches? they apply on 2.4.29 kernel and 2.6.9 TC. I use centos4 with a 2.6 kernel, so I can''t try these easily. Thanks

Hi, I use the patch (http://ace-host.stuart.id.au/russell/files/tc/tc-atm/) for accurate the packet scheduling on ATM/ADSL link and i think I''ve found a bug. I tried to write to the author but he didn''t answer me. I work on a Linux 2.6.17 with the iproute2-2.6.18-061002 package. I change the type of the cell_align char to short of the struct tc_ratespec in the file pkt_sched.h

Nothing against CentOS as a firewall, but you might consider a distro that is more focused as a plop'n drop "security applicance" distro: http://www.ipcop.org 4-zone segmentation (WAN, DMZ, LAN, WLAN) Integrated real-time and statistical logging, Snort IDS,

All, I am trying to configure hdlc support on T100P Digium card - everything seems ok... but it just does not work at all. I was able to compile all drivers, the light on the card becomes green when I plug T1 link.... but I even can't ping default router IP... there is no data coming back to me, so I am confused completely now. Also I tried both protocols - raw hdlc and cisco hdlc. The

Hi, Is it possible to put some kind of bridge which will do traffic shaping/prioritising between my 6 external IP addresses and my PPPoA modem interface? My other option is to put some kind of device at the edge of all my networks to shape the traffic in/out. I'd rather do it in one box if possible? thanks Mike

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 read the thread at http://mailman.ds9a.nl/pipermail/lartc/2006q1/018287.html and still don''t know how to fix this problem. It appears alot of work has gone into it but the HOWTO is so out of date it doesn''t even begin to addresses this method. So here are my questions 1. what is the current state of these patches? are they in a specific version? do i have to patch myself?

Hey, I''ve been scouring the web these past few days trying to find a suitable technique to load balance my network. Unfortunately I think my setup is very uncommon, so I''m looking to you guys to see if you can help. I currently have 2 ADSL modems, provided by the same ISP and terminating on the same gateway (I think having the same gateway is what is causing the problems, since

Hi all, ive got wondershaper working well with the highest download while maintaing minimal latency but the problem is this: ive got 2 nics in the linux router eth0 and eth1. eth1= internet interface but this is connected to a router say 10.0.0.190, now off that router there are other servers, mail server, domino server etc now if i shape on eth1 ingress and egress using the wondershaper script

J, What i meant is...like in Linux you make use of the two external connections and collate them as mentioned in the document. Can you try keeping the Linux box in front of the two windowze boxen and collate the two LAN connections coming from them as mentioned in the HOWTO???.

I have a recently installed Mellanox VPI interface in my server. This is an InfiniBand interface, which, through the use of adapters, can also do 10GbE over fiber. I have one of the adapter's two ports configured for 10GbE in this way, with a point to point link to a Mac workstation with a Myricom 10GbE card. I've configured this interface on the Linux box (eth2) using

Greetings list, Thanks to all who replied to my thread a few days ago "SIP devices with packet loss tolerance". One of the suggestions that came out of that thread was to replace routers at users' premises with ones that support QoS. I've used m0n0wall's QoS in the past with reasonable success, but it's quite a bulky and complex setup for deploying to remote sites which

Guys Considering the festive season is upon us, thanks to everyone contributing to the list and helping all the readers with your great input! I don''t want to mention names, I''ll most certainly leave someone out. With this mail I''d like to test some theory on bandwidth management, with my own successes and failures during the past year.

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

We are attempting to setup an automated system to build some Linux systems. We have utilised the PXELINUX bootloader after encountering the PXE 512Kb limit with bootp. We now have another issue which you may have already run into. In the DHCP configuration we specify pxelinux.0 as the bootfile, this works reasonable well, we call the Redhat vmlinuz and initrd.img files within the

Hi Maarten, Yes, I'm behind ADSL with PPPoE but I don't think it is related with my case. When my client disconnects from IceCast server for 15-20 seconds, my active downloads are not interrupted. It currently effects only the route to my IceCast server, other routes looks uneffected. I'm pinging IceCast server continuously and checking trace route periodically. It is comething like:
