That seemed like such a good suggestion. I created scripts to assign
the desired names to the desired MAC addresses and placed them in
/etc/network/if-pre-up.d/, and then added invocation in the interfaces
file, but I keep getting the messages (in syslog):
Dec 28 19:11:31 ve6wvc nameif: cannot change name of eth1 to eth0: File exists
The `file' here is the network device `eth0' -- ``ifconfig -a'' will
show both eth1 and eth0 are there, waiting to be upped. This looks like
a kernel limitation.
The workaround is something like:
# nameif foo HWADDR1
# nameif eth0 HWADDR0
# nameif eth1 HWADDR1
So I when there is an interface bar that (1) is down, and (2) has a name
we want, we just give bar a random name foo. If (2) is not true, we
just proceed ourselves, and when (1) is not true, we die screaming
aloud. Loosely:
# HWADDR_TO_RENAME=$(ip -l | grep -A1 eth0 | tail -n1 | awk '{print $2}')
# [ -n $HWADDR_TO_RENAME ] nameif foo $HWADDR_TO_RENAME
in both the scripts, _before_ the real naming.
Dec 28 19:11:31 ve6wvc nameif: cannot change name of eth0 to eth1: Device or
resource busy
Then, the eth1 is UP (busy). You might want to go to singleuser mode,
put the network down, and experiment a bit, just to grasp what's going
on.
A typical script was eth0.sh:

The scripts are OK.
Merry Christmas to you too.

Before finding this Email on the list, I experimented with exactly your
idea. Of course it worked. I stuck the following 3 lines in front of
the ifup -a in /etc/init.d/networking:
/sbin/nameif -s eth2 00:50:da:08:f0:4a # 3COM:set to eth2
/sbin/nameif -s eth1 00:40:05:45:19:22 # Linksys: set to eth1
/sbin/nameif -s eth0 00:50:da:08:f0:4a # 3COM:set to eth0
To the list readers/responders who suggested using the module interface,
thankyou. I'm sure that such a procedure wold also work. I just
happened to have both NIC's built into the kernel already - hence the
request.

2 NIC's, assigned in wrong order
Hello: I have two Ethernet cards (NICs) in a PII-300. The first recognized is an NE2000 ISA clone at IRQ10, and the second is a PCI at (shared) IRQ 12. I would like the second (the PCI) to be assigned as ETH0, and the first (ISA) to be ETH1. I've fiddled with the ether= append line for the kernel, and also the contents of the interfaces file in /etc/network to no avail. Anyone know how to force the assignment without resorting to ifconfig and route directly?

First of all, why does the name order matter? Second, iirc they are named by order of detection, so you could compile them in as modules and then load the modules in the naming order you want. From what you are writing, it is not relevant for this case, but if they both use the same driver, replacing their physical order in the slot should do the trick. I have rather similar problem.
