I've recently built up 4 file servers all using nearly identical hardware. On one of them, I installed Suse, the other three got Ubuntu. on the Ubuntu machines, if I run iptraf & monitor all interfaces, I only see one interface of four doing anything (there's actually 6 interfaces, but only four of them are configured for the bond). On the Suse machine, all four interfaces get pretty good throughput.

So something's wrong... it's either my config, Ubuntu's iptraf (which I'm pretty sure is not the case becasue I just downloaded and compiled from the latest iptraf source), or something with Ubuntu's bonding module or ifenslave program.

Can someone else verify, with iptraf, that more than one interface in your bond is working? It's easiest to see by simply running iptraf (available via Synaptic/apt*) & using option 2 which is "Genearl Interface Statistics".

I'm happy to post my config here if anyone's interested. I'm using 802.3ad for the bonding module.

Forgive me here if I'm not quite following what you're asking, but a recent problem with setting up wireless leads me to think I can verify.

I haven't used iptraf before, but I had to change my bonding because my wireless was recognized as eth1 and not wlan0. I had to change this in the files:

/etc/iftab

/etc/network/interfaces

The iftab had the actual MAC listed, while the interfaces had the information about interface startup. I can tell you that after I changed the references from eth1 to wlan0 that my wireless interface was then recognized/named correctly to the MAC.

I hope this helps.

Nope.

It did, however, make me restart my network interface. Now, after the restart, only eth5 is doing anything (as opposed to eth2 before).

hmm.

For anyone who comes across this post, 802.3ad works fine under Ubuntu, what does not work is the Linksys 2024. Oddly enough, the Linksys 2048 (the 48 port managed gigE switch) works fantastic... as does Ubuntu.
