In trying to track down some networking problems, I swapped the ethernet
adapter in my server. Since re-booting, it has been assigned the moniker
eth2 rather than eth1 (the motherbaord device is eth0).

So, how do I reset the second adapter to become eth1 again?

Hi Tony,

you can edit "/etc/udev/rules.d/70-persistent-net.rules" to assign the device
to your required needs.

At next reboot, the device eth0 or eth1 whatever will be connected to the
according network card.

Good luck!

Hans

You can edit "/etc/udev/rules.d/70-persistent-net.rules" file and adjust
it accordingly.

Edit /etc/udev/rules.d/70-persistent-net.rules or just remove it and
reboot.

Look at /etc/udev/rules.d/70-persistent-net.rules

Create a similar file, with the mac id of the card you want a specific
device id as ATTR(address ... etc and NAME="eth1"

Before you do that -- chances are you have already another device
configured to run as eth1, so look at the other files / other lines in
that file and see which device is configured to work as eth1.

Thank you all for the helpful replies. It's all working fine again :)
