My ubuntu 13.04 machine (ASUS M2n32SLI deluxe mobo) is loading one of two interfaces on the motherboard as "rename3". The other interface is eth0. No cable connected on eth0.
- Why is this so ?
- How do I fix this? I want to retain dynamic dns.

Here is one solution, on how to rename the interface. Most likely, there was something which went wrong under the setup of the device, so, let's roll on with it:
Open the file
And look for "rename3" in it.
You will find this:
NAME="rename3" on a pretty long line, so i suggest that you open the file in "gedit", and search for that word by pressing
Command for that:
sudo gedit /etc/udev/rules.d/70-persistent-net.rules
When you find it, edit it to desired name, like
NAME="wlan0" (if not taken) or something, that you can recognize it easily.
On the same line, you'll find another parameter called
KERNEL=="rename3". You don't have to edit this "kernel" parameter, as i am unsure myself what it is for. It works without changing that.
Now save the file, and close it.
After doing this, remember also to check your
/etc/network/interfaces file to reflect the interface’s name change.
Restart the service:
Not claiming to be an expert here, but here is what I found. After seeing one of my interfaces named "rename2", I checked the file /etc/udev/rules.d/70-persistent-net.rules. There I could see that both my second and third NIC had the same name, eth1. After changing the last of them to eth2, and rebooting, everything was back to normal.
