    Thank you for the effort.

    As I know and I just to inform you that the better way to configure network on RHEL7 is with using “nmcli” or “nmtui” commands.

    The second one is graphical mode.

    Hello Gabriel,

    Excellent post, congratulations.
    May I recommend a little correction in your text?
    The structure of the /etc/hosts file is:

    IP HostFQDN HostAlias[,HostAlias…]

    The file format was initially defined in RFC952 and the hostname in RFC953.
    As your artcles are a good reference, could be interesting to show it this way.
