Bonding on 2.4.3, ifenslave wierdness

At work we've been using Willy Tarreau's channel bonding patches against
linux 2.2.17, and it's been working just fine for us. Now, though, we need
to upgrade our systems to kernel 2.4.x (specifically 2.4.3), and we've been
having bad luck with the included driver. I'm using the
ifenslave.c available from beowulf.org that went with bonding.c 0.2
(ifenslave.c 0.7, Don Becker's version). I'm not sure if there is a new one
for the 2.4 kernel's driver....
I follow the directions precisely, but it appears that rather than
inheriting its MAC address from the first slave interface, bond0 tries to
push *its* MAC into every enslaved device. So I get HWaddr 00:00:00:00:00:00
across the board. It's also trying to set wrong IP/netmask/broadcast
Here are the commands I've executed:
(after starting without networking...)
ifconfig bond0 10.0.0.3 netmask 255.255.255.0 broadcast 10.0.0.255 up
ifenslave -v bond0 eth0
here is the resulting output:
ifenslave.c:v0.07 9/9/97 Donald Becker (becker at cesdis.gsfc.nasa.gov)
The hardware address (SIOCGIFHWADDR) of bond0 is type 1 00:00:00:00:00:00.
The interface eth0 is up, shutting it down it to enslave it.
Set the slave's hardware address to 00:00:00:00:00:00.
Set the slave's IP address to 0.0.10.0.
Set the slave's MTU to 1500.
Set the slave's destination address to 0.0.10.0.
Set the slave's broadcast address to 0.0.10.0.
Set the slave's netmask to 0.0.255.255.
Set the slave's flags 1043.
DEBUG: argc=4, optind=2 and argv[optind] is bond0.
SIOCSIFSLAVE: Invalid argument.
Now, I really don't know what's going on here; it seems almost as if
ifenslave is making these values up. What should I do? Do I have the wrong
version of ifenslave? I wind up with eth0 configured but at hwaddr 0 just
Note that I'm running these commands before *anything* touches any network
Thanks in advance for any help.
