I'm new to ubuntu and need to install the ubuntu xenial server (16.04) edition to install MongoDB into a VirtualBox. After installation I tried to change from dhcp to a static ipv4 address. So I changed the /etc/network/interfaces :
auto lo iface lo inet loopback allow-hotplug eth0 iface eth0 inet static address 192.168.56.5 netmask 255.255.255.0 gateway 192.168.56.1
and reboot the server
# but ifconfig -a shows only an enp0s3 interface without any IP address and lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host up loopback running MTU: ...
(sorry copy and paste will not work so I have to type it all)
did a reboot once more and tried sudo ifdown and afterwards ifup eth0 # but it gives allways : Cannot find device "eth0" Failed to bring up eth0
The VirtualBox Network Adapter is set to Host-only Adapter and I have already running another VirtualBox with Debian8 on 192,168.56.4.
Has anyone any help for me ?
