I am a new with Linux, having years experience with Windows servers/desktops and am having issues setting a static IP. I am using a method used for previous versions of Ubuntu, which doesn't seem to work with 16.04
I have used the command
sudo nano /etc/network/interface and added the following
iface enp0s25 inet static
dns-nameservers 18.104.22.168 22.214.171.124
I have rebooted the system and the Ethernet is pretty much dead, ping doesn't work at all. I have tried to modify
/etc/NetworkManager/NetworkManager.conf and made the following changes
#dns=dnsmasq (comment out the dnsmasq)
managed=true (changed from false)
With this I can get Ethernet to work sporadically, however it eventually fails.
I have tried this configuration on two other machines plus a virtual machine as well and all have the same results. I can confirm these settings work fine when I install Windows on any of these machines.
As well when I let DHCP auto configure, everything works fine no issues.
I figure I am missing something here, setting up a static IP should not be difficult at all.
