View Full Version : [ubuntu] ethernet address automatically changes on a network interface

September 1st, 2009, 03:26 PM
Every time when I boot my Ubuntu 9.04 ethernet address and the name of a network interface are changed (e.g. eth14 -> eth15 ...). What is the cause of that - NetworkManager or something else?


# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

Not necessarily Network Manager... I've seen this before in a couple of threads - this (http://ubuntuforums.org/showthread.php?p=7870196#post7870196) being the most recent.
