(Pretty > much the same i guess) Bonding Interfaces gives them a single virtual IP interface. This means that you cannot connect them to two seperate networks. as suggested here. You can use routing and so on through another device to interconnect between the two networks (ADSL -> LAN), but direct connection as being done with two separate NICs is not possible when they become bonded. As for a good document on exactly how to accomplish the Interface bonding, I highly suggest this: https://help.ubuntu.com/community/UbuntuBonding > > What i want... is my server A, load balance both links... this network is not > a big one (only 80 Users... ) but on > another one...

Then for each additional link to be load balanced (not to be confused with bonded, bonding and load balancing are two very different things) you pick any order and set a route with the same metric as the default gateway on the router and create a rule similar to: source address - 0.0.0.0 -> destination address - 0.0.0.0, gateway - , interface - . > I'd like some advices here... if anyone has some ideas... before trying > something like this: > http://www.firewall.cx/ftopicp-15193.html (Imagine that with... 4 links at > least xD) > > Thanks in advance! > > -- > Santiago Zarate > santiago...@ubuntu.com > (+58) 4129864175 > (+58) 4241073905 > > -- > ubuntu-server mailing list > ubuntu-server@lists.ubuntu.com > https://lists.ubuntu.com/mailman/listinfo/ubuntu-server > More info: https://wiki.ubuntu.com/ServerTeam > Hope this helps! -Nick -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam

However, it would not work AT ALL when I tried to add vlans on top of a bonded interface. I filed a bug about it here: https://bugs.launchpad.net/ubuntu/+bug/352384 , but you'll see it has gotten zero attention, so good luck if you file a bug report. I wonder though, if I use pre-up entries to create the bond device, maybe then it would work with vlans...

RE: Interface bonding
Hi, I have several servers using the bond configuration on 8.04. I found the most effective way to enable this was to do the modprobe configuration (though the URL you posted has better instructions than I did), then I make the following in the interfaces file: auto bond0 iface bond0 inet static address 10.10.10.10 netmask 255.255.255.0 gateway 10.10.10.1 post-up ifenslave bond0 eth0 eth1 I originally had the line: post-up ifenslave bond0 eth0 eth1 replaced with: slaves eth0 eth1 However did not get consistent operations. I am using mode 1 for all teams. Thanks. Andrew. -Original Message- From: ubuntu-server-boun...@lists.ubuntu.com [mailto:ubuntu-server-boun...@lists.ubuntu.com] On Behalf Of Serge van Ginderachter Sent: 18 June 2009 10:43 To: ubuntu-server Subject: Interface bonding Hi all, I have been following https://help.ubuntu.com/community/UbuntuBonding to set up a bond of two network interfaces, and it seems to me this documentatuoin has certain flaws. No problem with the Module Alias Configuration. AFAIK this configuration will already make sure that the bonding module is probed and loaded. I then have some remarks on the interface configuration part. * loading and unloading the module through pre-up and post-down statements is not necessary, as the loading already happens in de modproe.d config, and might even be unwanted in tha case were one has multiple bonds configured, which would (try to) unload the module after bringing one bond down, whilst it still being in use for another one. * configuring the bond (ifenslave bond0 eth1 eth2) in the (post-)up statements didn't work for me: it seemed (post-)up happens after configuring an ip, but at that time the bond is not configured yet, and configuring the ip results in an error. I'm not totally sure if this is eneral logical behaviour or if I just messed something up at one point in my config trial and error. * finally, this howto does not mention the by far easier method explained in /usr/share/doc/ifenslave-2.6/README.Debian: it's just enough to use the "slaves eth0 eth1" in the iface bond0 stanza It might be interesting to have those remarks reviewed, to check if my evaluation is correct.

Re: Interface bonding
Hi, the problems resides in the outdated documentation which does not contains the new infos on how to bond interfaces. I have not with me my configs, so I can't send you and in few hours I will leave for holydays. Anyway, google around and you will find the new configs.
