So.., once this modules is compiled, how do i set up two of many eth cards in one machine to work like this?. May be it's automatically?.
If i have a machine acting as router, and it has 4 eth cards, and two of
these, are connected to another one machine. How can i tell my router, wich of those are de two i want to use "bonded" ?

Thanks !

| First off, I have no actual experience with this, and I am just going
| off the kernel documentation.  It is possible, and you even remembered
| the term correctly - ethernet channel bonding.  What will most likely be
| the deciding factor on whether or not you can actually set this up is if
| the other end of the two ethernet channels (probably your ISP) supports
| bonding.  Here's the a direct quote from the relevant kernel
documentation.
|
| <BLOCKQUOTE>
| Bonding driver support BONDING
|
| Say 'Y' or 'M' if you wish to be able to 'bond' multiple Ethernet
| Channels together. This is called 'Etherchannel' by Cisco,
| 'Trunking' by Sun, and 'Bonding' in Linux.
|
| If you have two Ethernet connections to some other computer, you can
| make them behave like one double speed connection using this driver.
| Naturally, this has to be supported at the other end as well, either
| with a similar Bonding Linux driver, a Cisco 5500 switch or a
| SunTrunking SunSoft driver.
|
| This is similar to the EQL driver, but it merges Ethernet segments
| instead of serial lines.
|
| To compile this driver as a module, choose M here: the module
| will be called bonding.

| Good luck & let us know if you get this working,

See the file /usr/src/linux-2.6.0/Documentation/networking/bonding.txt for more information on how to use ethernet bonding. Quick summary is:

1: Compile kernel with bonding, or compile & insert the module.

2: Compile and install the userspace tool ifenslave as follows:

# cd /usr/src/linux-2.6.0/Documentation/networking
# gcc -Wall -Wstrict-prototypes -O -I/usr/src/linux/include \
ifenslave.c -o ifenslave
# cp ifenslave /sbin/ifenslave

3: Setup bonded interface & enslave ethernet interfaces:

# ifconfig bond0 192.168.0.1
# ifenslave bond0 eth0
# ifenslave bond0 eth1

At this point the bonded interface should work.

Have fun,
