[LARTC] LoadBalancing on many asimetric different dsl's.
Hi, my company have just bought new network and I have question about one problem. As in topic we must use few completely different dsl's and balance traffic between them. 2M/0,5M 4Mb/0,5M 8M/0,5M M=Mb/s I've never done such thing before so I have doubts how it will work. If the links are symmetric 2/2 4/4 8/8 there is no problem because with weights I can compensate the difference between them and achieve nice results. But what in my situation? My questions are: how to set load balancing to get all links equally loaded and avoid situation when the up load will be full and download almost empty? I believe this situation can happen due to fact that load balancing is based on flows and for example p2p or smpt/pop3 will eat whole upload. If my problem isn't clear I'll try to explain it better later. Thanks in advance.

Re: [LARTC] LoadBalancing on many asimetric different dsl's.
Hello, I've done this some montsh ago, with a command like: ip route add default equalize scope global nexthop via $EXTGW1 dev $EXTIF1 weight 1 nexthop via $EXTGW2 dev $EXTIF2 weight 1 However, this is not the problem. While loadbalancing of simple requests worked fine, there where problems when you worked with connections. I mean HTTPS, of FTP connection for example. The problem was fo me that the system trys to send packets of the same connection throught different gateways, so with different IP source (each DSL connection was from different ISP). This caused the server not to understand why the same connection sent packets with 2 different source IP ;) Well, I hope you understand me. If you would do real load balancing, and in a proper way, you should not only do it by link charge, but route packets by connection to. (routing all packets of the same connection through the same gateway) This is caused because you must flush the route cache some times (or packets to a destination will allways take the same route, wich is not a loadbalance). So if someone has done it and doesn't have this problem, I'm interested too :) Thanks!

[LARTC] routing patches seem to break output nat
Hi We have applied the routing patches from http://www.ssi.bg/%7Eja/#routes. To 2.6.15 this seems to have broken our output natting. Has anyone else experienced this or any advice on how to fix.

[LARTC] traffic shaping question
Hi list, I have read the lartc 9th chapter, the bandwidth management part. I think I understand the principle, but I have a question. So I have a firewall that has several different interfaces. The most important for my question is the Internet interface, which is a 2mbps leased line. I have an interface into the protected network, I have a DMZ interface, and I have an interface with direct connection to a client. Here is what I need: Internet - DMZ + Internet - LAN + Internet - firewall traffic together should not exceed 1.5mbps At the moment I have a tbf, that limits everything that goes to the LAN, and another that limits everything going to the internet. I would like to shape the incoming traffic from the internet. OK, I understand that I cannot influence the senders out there not to try to send me packets, I can only influence how fast these packets are sent from me. But can I somehow treat all incoming traffic together? Because my knowledge at the moment is only some shaping possibilities on the LAN interface and on the DMZ interface. I have only one idea, but I don't know if it is feasible, and if it is, how to do that. So I thought that I will create a virtual interface, and route all traffic from the Internet through this one. So incoming on Internet interface, outgoing on virtual interface, and from there incoming on the firewall machine, or outgoing on the LAN or the DMZ interface. Does it sound good? How can I do that? (I suppose I have to read other chapters in the lartc guide. Could you point me out where to start? What to look for?) Or is there another solution? What would you recommend?

RE: [LARTC] HTB? (NEWBIE)
How the guide say I expect to see on router (with command tc -s qdisc ls dev eth0) that unclassified traffic, like ssh, get rounded to 20: but it doesn't happen. - Traffic just doesn't get rounded to a class. If you want traffic going to a class you need to specify a filter. Did you by chance man the default class 1:30. Any traffic not classified should end up there. - Packet shaping is only done on the Egress/root side of an interface. That is why you will only see stats for that. You won't see stats for the ingress side. Does this answer any of your questions?

Thanks for all your answers. I ask my question in different way because I still don't get answer which will be satysfying for me. Did anybody set similar configuration in the past? Have someone any suggestions how to set it to configure loadbalancing to avoid situation when one link is empty or only upload is used and other links are full. Does weights ensure that upload and download on all links with different up/down speeds will be equally loaded?

I believe this situation can happen due to fact that load balancing is based on flows and for example p2p or smpt/pop3 will eat whole upload. If my problem isn#039;t clear I#039;ll try to explain it better later. Thanks in advance.

Re: [LARTC] DGD patch not detecting dead gateway
Hi! Thank you. Manish Kathuria escreveu: On 1/19/07, Tom Lobato [EMAIL PROTECTED] wrote: Hello all! I applied http://www.ssi.bg/~ja/routes-2.6.8-10.diff patch to kernel 2.6.8.1 and it works fine, or almost fine. It does the load balancing well, but when one link is dropped it continues to try it. At the end of http://www.ssi.bg/~ja/nano.txt it is said to ping gateway 1 and gateway 2, for the kernel to know if that route is working, but since my linux is connected to the links through 1 dedicated link and one adsl modem, I tryied to: 1) remove ethernet cable from linux nic: the patch worked well, began to send traffic only to the yet working, link. 2) remove telephone line from adsl modem (or external ethernet cable from the dedic. link switch): the patch didn't work, continued trying to send traffic to the dropped link. So, I think its happening because linux, since it can ping the switch (or adsl modem) thinks that link is good. Did you have this problem? Some hint? Thank you! My experience has been mixed. The patch worked very well in many cases but in some it worked only if the first hop gateway was down and not any of the subsequent hops. So as you mentioned its happening since it can ping the switch / modem, it thinks the link is good. You can make a script which will keep on running in the background and check it the links are up or not and if any of the links is down, it can change the default route and provide a failover. Oh yes, in really I already made such scripts, before to know this patch, using 4.2. Routing for multiple uplinks/providers from Adv-Routing-HOWTO information. But facing this problem, I think the best solution is to use it again. Somebody know if there is working in progress for solve this? Is there some goal for include this patch to the mainstream kernel? What is the possibility of it?

[LARTC] determine internet connection duration
Anyone has idea of what would be the best way to track connection time some a particular user to the internet ? Imagine a wifi network where the users will connect to the system via DHCP ( there is no PPPOE session involved ). If there is a need to track internet usage based on connection time ( to the internet ), what would be the best way to track it ? Appreciate any input or ideas. ___ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
