You might want to look for the interface under different names.

I just had the same problem, I can’t find eth1.

if I run

lshw -class network

I do find disabled networks like *-network:1 disabled

Cross referencing the Mac address from the network with ifconfig I found the interface is actually called ens4 . Running ifconfig ens4 up and then reconfig /etc/network/interfaces.d/50-cloud-init.cfg works, now private networking is working.

Solution steps are explained in great detail here: https://www.digitalocean.com/docs/networking/private-networking/how-to/enable/

As the previous poster mentioned, the device is there, just disabled. The linked article explains how to set it up after droplet creation.

Hi, I have same problem. Debian 9.3.

Same problem here. There is no eth1 interface listed by ifconfig
I am using Ubuntu LTS.

same problem here, have 3 droplets, one of them dont ping anymore

@jvmmdev Did you ever figure out what it is?

Hey guys.

For all that was wondering. I never resolved this. I got sick of waiting for Digital ocean to respond to my ticket once a day…if that. I waited 3 days for them to respond. To which is was never resolved.

So I just destroyed my droplets and re-install 2 with private networking simultaneously.

Problem fixed.

Yes, adding private network on prior created instances not working, we have tried several ways to make the private networking work with initially crated instances, nothing work,

only possible solution is to destroy and create again.

I had the same issue and nothing helped. I decided to enable ipv6 and that, somehow, made eth1 start showing up when I run ifconfig -a.

I ran into the same problems with Ubuntu 16.04 LTS ..old install trying to make a private network
but I managed to get it to work by following the steps for Ubuntu 14.04 … I think there is a problem with the tutorial
