System ON!
==========

The last step is to enable libeufin-nexus to :ref:`import incoming bank
transactions <receive-transaction-data>` (cash in) and to :ref:`trigger
outgoing bank transactions <sending-payments>` (cash out).

First, check that libeufin-nexus is correctly configured by running the following commands:

.. code-block:: console

  # sudo -u libeufin-nexus libeufin-nexus ebics-setup
  # sudo -u libeufin-nexus libeufin-nexus ebics-fetch --transient
  # sudo -u libeufin-nexus libeufin-nexus ebics-submit --transient

If you have old transactions after the date YYYY-MM-DD that you wish to import into the database, run the following command:

.. code-block:: console

  # sudo -u libeufin-nexus libeufin-nexus ebics-fetch --transientt --pinned-start YYYY-MM-DD

None of those commands should fail. If they all work, you can enable the services:

.. code-block:: console

  # systemctl enable --now libeufin-nexus.target

Now that we know that libeufin-nexus is working correctly, we still need to check that communication with your bank is working properly. We will test this later, at :ref:`the end of the manual <regional-use>`. The system should only be considered functional after a successful :ref:`cash in <regional-use-cashin>` and :ref:`cash out <regional-use-cashout>`.
