Post subject:  Ethernet Network Bridge
I have two 100MB network cards in my knoppmyth machine here and I am trying to bridge them so I can get better network speeds and transfer rates.

I used apt-get install to grab the bridge-utils. After reading and following many guides and tutorials, everything seemed to work but still no network connectivity. Briefly, this is what I did.

ifconfig eth0 0.0.0.0
ifconfig eth1 0.0.0.0
brctl addbr "bridgename"
brctl addif bridgename eth0
brctl addif bridgename eth1
ifconfig bridgename 192.168.0.115 netmask 255.255.255.0 #That's the IP I use for that machine

This brought everything up, and ifconfig looked good, but I could not ping the gateway (192.168.0.1) or google.com, or any other computer on the network.

Optionally, I tried using this "dhclient bridgename" which after the third time I ran the command got an IP from the DHCP server, but even then I still could not ping out.

Can anyone help with getting my bridge to work?

it looks like you should be running spanning tree.

I also think that what you might be wanting to do is bonding and not bridging.

With bridging you can join up ethernet segments. Say you have an office in LA and
one NY and you want them to be on the same ethernet segment.

Second on what you are looking for is bonding not bridging. bridging does not give you any extra speed. Note that to use bonding you will need a switch that can do trunking, or multiple switches.

Yeah, I have a linux box on both sides and a 1000mb switch. So I will give it a try and see if I can get it to work
