Configure at least one network interface to access the Internet or
|

suitable local repositories.

|
||||
Some distributions add an extraneous entry in the ``/etc/hosts`` file that
|
||||
resolves the actual hostname to another loopback IP address such as
|
||||
``127.0.1.1``. You must comment out or remove this entry to prevent name
|
||||
resolution problems. **Do not remove the 127.0.0.1 entry.**
|
||||
This step is especially important for `metal` deployments.
|
||||
|
||||
We recommend adding the Secure Shell (SSH) server packages to the
|
||||
installation on target hosts that do not have local (console) access.
