I've tried to find a way to configure a new connection manageable by NetworkManager using a terminal/shell script all day long, but I've been unsuccessful.
The reason is that I have a lot of openvpn configuration files and I wanted to have a nice and fast way of importing them, also beacuse NetworkManager openvpn plugin doesn't parse the certificates embedded into configuration files, so the only way to configure a new VPN connection is to do that manually via the GUI after I run a script to extract the certificates from the config files, which is a rather long and tedious process.
I found that on RedHat the nmcli utility has the ability to configure a new connection in this way:
nmcli con add [...]
However this is not possibile on (standard) Linux Mint 17.1.
I tried to add a new connection manually, adding a new file in
[connection] id=VPNConnection id=3389cf54-949e-4c69-a746-864f0f8720b8 type=vpn [vpn] service-type=org.freedesktop.NetworkManager.openvpn fragment-size=1300 connection-type=password-tls password-flags=1 auth=MD5 tunnel-mtu=1500 cipher=AES-256-CBC comp-lzo=yes cert-pass-flags=0 remote=[vpn provider] port=[vpn port] mssfix=yes username=[username] remote-cert-tls=server cert=[user cert] ca=[ca cert] key=[user priv. key] [ipv6] method=ignore [ipv4] method=auto
but this new configuration doesn't show up in NetworkManager.
Also, I don't have any ~/.gconf/system directory, neither under my personal home nor under /root.
Where could NetworkManager read configuration files from?
