Network interfaces assignment problem

[Perdido]

Hello all,

I have two network interfaces. They have the same names in all my previous kernels (eth0 and eth1). I am using Debian Sid.

But when I boot my computer with a new kernel (2.6.5) from a completely new .config file (I was not very happy with the oldest one) the interfaces assignment has changed and they are renamed eth1 and eth2. So, the interfaces configuration doesn't match and they don't work.

Could you help me?.

Debian Sid (as above) ??

Perdido... See if adding

alias eth0 <module>
alias eth1 <module>

to /etc/modules.conf and running

depmod -ae

fixes that. Not sure if it will, but might be worth a try.

[gehidore]

sorry missed that.

From http://www.linux.org.uk/~davej/docs/post-halloween-2.6.txt

- Users of boxes with >1 NIC may find that for eg, eth0 and eth1 refer to
the opposites of what they did in 2.4. This is a bug that will be fixed
before 2.6.0. One option (or management workaround) for this is to use
'nameif' to name Ethernet interfaces. There is a HOWTO for doing this at
<http://xenotime.net/linux/doc/network-interface-names.txt> Guess it didn't get completely fixed before 2.6.0, or something like that. See if the "nameif" program or that HOWTO helps you at all.

Wouldn't that mean eth0 is now eth1 and eth1 is eth0? What about eth1/eth2? :confused:

I was hoping what I previously suggested would force the kernel to use eth0 and eth1 instead of 1 & 2.

Could you help me to know the modules names?. I don't know how to do it. I'm just a newbie.

Thank you for your help.

bash$ lsmod
This lists the modules running on your machine.

Maybe I'm missing something, but why not just make changes to /etc/network/interfaces ?

Well, nameif still might be helpful anyway. It moves you away from any dependence on ethN at all.

Cause we like doing everything the hard way. :)

Does Debian use /etc/network/interfaces as SuSE does not?
