How do I add a second IP-address in Ubuntu 17.10 like the old days where you could add eth0:1, eth0:2 etc.
I've tried but lots of commands have been deprecated like ifup, ifdown etc. and the network settings doesn't seem to be the same as it used to.
I might be wrong here but I can't seem to figure it out.
I have a network card eth0 where I want to add a second IP on the same subnet.
If I add eth0:1 to /etc/network/interfaces but I can't seem to get the interface up.
Is there another way to do this permanently?
EDIT:
/etc/network/interfaces:
auto lo
iface lo inet loopback
auto eth0:1
iface eth0:1 inet static
address 10.100.1.39
netmask 255.255.255.0
I've tried to add the information on eth0 too but it doesn't seem to make a difference.
This if the output of ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 10.100.1.38 netmask 255.255.255.0 broadcast 10.100.1.255

Turns out in 17.10 you edit your network settings in /etc/netplan/01-netcfg.yaml
All I had to do was add the second IP next to the existing one separated with a comma like this:
Then you run:
Hope this helps someone in the future.
