My new Ubuntu 11.04 server is having issues with the two Ethernet ports on the motherboard. I only need one port, eth1 so I am trying to disable eth2.
sudo ifconfig eth2 down which only worked temporarily as eth2 repopulated in
ifconfig within a short time.
I then modified /etc/network/interfaces to disable it:
# The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth1 iface eth1 inet dhcp #auto eth2 #iface eth2 inet dhcp
sudo /etc/init.d/networking restart and even rebooted the system.
For some reason, after about 10-30 mins, eth2 re-enables itself and interrupts all network traffic on eth1. How can I prevent eth2 from ever enabling itself?
