Cannot enable private IP address

I am following the tutorial given in the link to set up private IP in the existing droplet.I added this

auto eth1 iface eth1 inet static address Droplet_Private_IP/16auto eth1 iface eth1 inet static address Droplet_Private_IP/16

I substituted the ‘Droplet_Private_IP’ with my Pirvate IP and ran the command

“sudo systemctl restart networking”

Now I get the message

“Job for networking.service failed because the control process exited with error code. See “systemctl status networking.service” and “journalctl -xe” for details.”

sadly the tutorial doe not say anything as what to do if we get any error message so here I want to ask what to do?

I ran the command “systemctl status networking.service” and I get:

● networking.service - Raise network interfaces Loaded: loaded (/lib/systemd/system/networking.service; enabled; vendor preset: enabled Drop-In: /run/systemd/generator/networking.service.d └─50-insserv.conf-$network.conf Active: failed (Result: exit-code) since Sun 2018-06-03 10:40:48 UTC; 3min 57s ago Docs: man:interfaces(5) Process: 6245 ExecStop=/sbin/ifdown -a --read-environment --exclude=lo (code=exited, sta Process: 6328 ExecStart=/sbin/ifup -a --read-environment (code=exited, status=1/FAILURE) Process: 6321 ExecStartPre=/bin/sh -c [ “$CONFIGURE_INTERFACES” != “no” ] && [ -n "$(ifq Main PID: 6328 (code=exited, status=1/FAILURE)

Any help?

Thank you!

Why you have this duplicity in config ?

auto eth1
iface eth1 inet static
address DropletPrivateIP/16auto eth1
iface eth1 inet static
address DropletPrivateIP/16

You should have one definition in config:

auto eth1
iface eth1 inet static
    address DropletPrivateIP/16

or try ( I never used /subnet, rather specify netmask ):

auto eth1
iface eth1 inet static
    address DropletPrivateIP

Try reboot Droplet for networking changes. If Droplet hangs use console to comment out eth1 definition.
