We have an Ubuntu server setup in a remote location awhile ago, with GUI packages. The System Settings via the GUI were used to setup the network config. It's currently at version 14.04 LTS. There is ssh access to the remote server.
In particular, we're looking to update the DNS client settings. Where does Ubuntu 14.04 store these settings that were created via the GUI System settings? They're not in /etc/resolv.conf nor /etc/resolvconf/resolv.conf.d head/base/tail files nor /etc/network/interfaces nor other typical config files when the system is setup without the GUI packages.
Is the only option to use a remote version of Unity .... or just get someone on-site and remedy this thru the GUI?
