Is it possible to TURN OFF private network once enabled on a droplet?

In order to disable private networking from the command line, you need to edit the file /etc/network/interfaces It will look something like this:

# 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 eth1 eth0
iface eth0 inet static
        address 95.85.37.158
        netmask 255.255.255.0
        gateway 95.85.37.1
        dns-nameservers 8.8.8.8 8.8.4.4
iface eth1 inet static
        address 10.129.176.173
        netmask 255.255.0.0

eth0 is the public interface, while eth1 is the private interface. Remove the sections about eth1 (highlighted above), and restart your droplet:

sudo shutdown -r now

I known this is a long procedure, but if you are in a hurry, maybe create a snapshot image of this droplet, delete this droplet, then create a new droplet from the image. This new droplet is by default without private network. This is what I have done.

Any one have a response to this?
