Delete eth0 avahi from the ifconfig list

Hello this is the response I get from ifconfig. Now I have two eth0 things being showed up. I need to delete the second one which says eth0:avahi. I posted my ifconfig's response on a site as I has problem using wired internet, and they suggested to remove the eth0 avahi, to get internet.

But I am a newbie to linux networking and have no idea how to delete this.

From ubuntu sai

• Is there an avahi listing in your /etc/network/interfaces file?

  Try deleting it from there.

  sai : auto lo iface lo inet loopback this is the content in /etc/network/interfaces file
  From Petey B

• Avahi is a daemon (a service) which is responsible for several things, including attributing you an IP address when DHCP (automatic IP address from a DHCP server on the network) fails.

  The fact that eth0:avahi appears means that the system failed to get an IP on the eth0 interface (your wired network interface).

  Normally, NetworkManager should take care of attributing an IP automatically to eth0. However, you could try to force it. Your /etc/network/interfaces doesn't list eth0, so what you can try is the following.

  First, edit /etc/network/interfaces (with sudo gedit /etc/network/interfaces for example) so it reads this:

  auto lo
  iface lo inet loopback
  
  auto eth0
  iface eth0 inet dhcp
  

  This will tell the computer to consider getting an IP automatically for eth0. Then, restart the network with:

  $ sudo /etc/init.d/networking restart
  

  If it still doesn't work, there might be other issues:

  • are you sure there is a DHCP server on your network? If there isn't, you'll have to setup the IP address manually;
  • if you have a DHCP server, it probably means that your problem is a hardware issue. Check that the cable is well plugged and lights are on on both sides of it.
