I'm running a standard Raspbian installation (2014-01-07 image version, no extra software installed). All I want to do is to shut down the
eth0 interface. The problem is that this works for a few seconds only, and then the interface all of a sudden is automatically up again.
auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp auto eth1 iface eth1 inet dhcp
I've tried shutting the interface down with both
sudo ifconfig eth0 down and
sudo ifdown eth0 to no avail. I suspect this problem is somehow related to DHCP or the
dhclient program itself, since the interface releases its DHCP-assigned IP address for a short time, but apparently re-installs that same IP address just a few seconds later again.
Can anybody help me here? I'm stuck with this. Thank you very much!
