Where does Network Manager write connection settings for eth0?

In Ubuntu I have configured network through network manager.

Every thing is working fine.My machine is pinging self machine as well as remote machine. but file /etc/network/interfaces doesn’t contain eth0 details.

I also looked into file /etc/networkmanager/networkmanager.conf but there is no entry for eth0 details.

So where does the network manager write network details??

Answer

Network Manager stores system-wide connection information in the /etc/NetworkManager/system-connections/ directory, with one file for each named connection. For eth0 it may have a default name such as Wired connection 1.
