Deciso: OPNcentral
|
|
===================
|
|
|
|
As part of the OPNsense Business Edition, Deciso offers a plugin to keep all your firewalls up to date and have
|
|
an easy entry point to manage them.
|
|
|
|
|
|
Installation
|
|
---------------------------
|
|
|
|
After acquiring a license, you can switch to the commercial software repository containing OPNcentral. In order to
|
|
install, just go to :menuselection:`System->Firmware->Plugins` and search for :code:`os-OPNcentral`.
|
|
|
|
|
|
Register new hosts
|
|
----------------------------
|
|
|
|
Before adding a host, you need to generate an API key and secret from the machine you will grant accesss to.
|
|
API keys are managed in the user manager (system_usermanager.php), go to the user manager page and select a user.
|
|
Somewhere down the page you will find the API section for this user.
|
|
|
|
Click on the + sign to add a new key. When the key is created, you will receive a (single download) with the credentials in one text file (ini formatted).
|
|
The contents of this file look like this:
|
|
|
|
.. code-block:: c
|
|
|
|
key=w86XNZob/8Oq8aC5r0kbNarNtdpoQU781fyoeaOBQsBwkXUt
|
|
secret=XeD26XVrJ5ilAc/EmglCRC+0j2e57tRsjHwFepOseySWLM53pJASeTA3
|
|
|
|
|
|
Next go to the Hosts section of the management menu in :menuselection:`Management->Hosts` and add a new host, copy
|
|
the url from the machine and the API key and secret generated above.
|
|
|
|
.. Note::
|
|
|
|
You can disable certificate validation if your using a self-signed certificate, although we advise to generate proper
|
|
certificates for the machines.

Connect to managed machine
|
|
----------------------------------
|
|
|
|
On various management pages there are direct links available to login to the firewall in question.
|
|
Usually connected nodes are shown with a link which opens in a new tab when clicking.
|
|
|
|
The example below shows a link in the firmware status page which will open :code:`https://node1.opnsense.local`.
|
|
|
|
.. image:: images/OPNcentral_status_uptodate.png
|
|
:width: 100%
|
|
|
|
|
|
When the management server is allowed to access the OPNcentral components on the connected node it will automatically login
|
|
after the link is clicked with the proper credentials assigned to the api token user.
|
|
|
|
If the latests Business Edition is installed on the managed machine, but access prohibits automatic logins, you will be redirected to the login page.
|
|
|
|
When the connected machine is not using the business edition, it's not possible to use the link, a message such as the following will be presented to the
|
|
user:
|
|
|
|
.. image:: images/OPNcentral_auto_login_unavailable.png
|
|
:width: 60%
|
|
|
|
|
|
.. Note::
|
|
|
|
Make sure your browser trusts the remote node otherwise the browser can't access the machine and will signal an issue with the
|
|
software version.
|
|
|
|
|
|
Machine firmware status / upgrade
|
|
----------------------------------------------------
|
|
|
|
All connected and enabled machines can be contacted using the :menuselection:`Management->Status` page, when visiting the
|
|
page all connected machines will automatically be contacted to report their status and installed version.
|
|
|
|
.. image:: images/OPNcentral_status_toupdate.png
|
|
:width: 100%
|
|
|
|
When an update is available, it will be shown in the list, including if this upgrade requires a reboot. The upgrade button starts
|
|
the upgrade procedure, but will only upgrade machines that will require a reboot if **Enable reboot** is checked.
|
|
|
|
.. Tip::
|
|
|
|
.. raw:: html
|
|
|
|
Use the refresh <i class="fa fa-refresh fa-fw"></i> button to request status again.
|
|
|
|
|
|
The upgrade wheel starts spinning when an upgrade was requested, since the upgrade itself can consume some time, you can revisit the
|
|
status page later (or press refresh) to show the new status.
|
|
|
|
|
|
Machine service status and control
|
|
----------------------------------------------------
|
|
|
|
The service status and control page provides an overview on all managed OPNsense firewalls connected to OPNcentral and
|
|
offers the ability to restart services when needed.
|
|
|
|
.. image:: images/OPNcentral_service_status_overview.png
|
|
:width: 100%
|
|
|
|
In the screenshot above there are 7 machines managed by OPNcentral, for every configured service there's an icon reflecting the
|
|
status of the service.
|
|
|
|
|
|
.. raw:: html
|
|
|
|
<i class="fa fa-window-close-o text-danger" style="color:#F05050"></i> Stopped (inactive, but configured) <br/>
|
|
<i class="fa fa-check-square-o text-success" style="color:#9BD275"></i> Running (active) <br/>
|
|
<i class="fa fa-exclamation-triangle"></i> Host unreachable or misconfigured <br/><br/>
|
|
|
|
|
|
When you click one of the service icons, the icon changes into a checkbox which can be used to restart the selected
|
|
services with the button below the table.
|
|
|
|
.. Tip::
|
|
|
|
The link in the host column brings you directly into the service control page of the selected firewall.
|
|
|
|
|
|
Machine resource status
|
|
----------------------------------------------------
|
|
|
|
In order to gain insights into the managed machines there is a resource page available which queries all connected
|
|
firewalls and reports aggregated status about them.
|
|
|
|
While collecting data for a machine there's a spinner visible, as soon as information is collected you can view
|
|
relevant information per node.
|
|
|
|
.. image:: images/OPNcentral_resources_host.png
|
|
:width: 100%
|
|
|
|
From left to right the following information is available:
|
|
|
|
* Host information
|
|
|
|
* Host name (description)
|
|
* Version installed
|
|

|
|
* Aggregated HA status (when configured), MASTER when all interfaces are, BACKUP when at least one is demoted to BACKUP
|
|
* Root file system usage
|
|
* Gateway status including maximum delay
|
|
|
|

|
|
* Source tracking table usage
|
|
* Current traffic in/out, tooltip the piechart to show protocol name (or number) with current rate
|
|
|
|
|
|
.. Tip::
|
|
|
|
When headings are underlined, a click brings you to the relevant module of the firewall in question.

Provisioning / sharing settings
|
|
----------------------------------------------------
|
|
|
|
The provisioning tool offers the ability to configure some settings in a more centralised manner. Inspired by the functionality that
|
|
is offered for high-availability setups, you can distribute global settings among all connected firewalls for various configuration options.
|
|
The central host acts as a template in this case.
|
|
|
|
In order to configure the settings that should be shared, you can configure the "classes" to synchronize in the host settings :menuselection:`Management->Host configuration`.
|
|
|
|
.. image:: images/OPNcentral_provisioning_host_classes_setup.png
|
|
:width: 50%
|
|
|
|
Here you will find the same options as are available under :menuselection:`System->High Availability->Settings`.
|
|
After configuring the desired parameters, you can use the Provisioning page (:menuselection:`Management->Provisioning`) to
|
|
inspect status and push options to the attached firewalls.
|
|
|
|
|
|
.. Warning::
|
|
|
|
Be **very** careful pushing settings to your connected firewall which may disconnect your session, such as firewall and routing related
|
|
options. The central management host can't predict if settings you plan to make lead to an inaccesible firewall.
|
|
|
|
|
|
All provisioning classes known by the management machine will be shown in the table, combined with the status of each section.
|
|
OPNcentral calculates if settings are equal, keeps track of changes and restarts related services when needed.
|
|
|
|
.. image:: images/OPNcentral_provisioning_status.png
|
|
:width: 100%
|
|
|
|
You can either selectlively reconfigure specific hosts with the checkbox or reconfigure all at once on command.
|
|
|
|
.. raw:: html
|
|
|
|
<i class="fa fa-exchange text-success" style="color:#9BD275"></i> Class equals this machine (nothing todo) <br/>
|
|
<i class="fa fa-refresh"></i> Changes ready to commit <br/>
|
|
<i class="fa fa-question-circle"></i> Unknown yet configured class <br/>
|
|
<i class="fa fa-times text-danger" style="color:#F05050"></i> Unable to connect <br/><br/>
|
|
|
|
|
|
.. Tip::
|
|
|
|
When users and groups are synchronized, the existing api key+secret is merged into the user with the same name to prevent access
|
|
issues after reconfigure. To avoid issues, make sure there's a unique username with proper credentials before using
|
|
the synchronization.
|
|
|
|
|
|
.. Note::
|
|
|
|
Since various firewall sections depend on aliases, OPNcentral checks if aliases are used before removing local aliases
|
|
from the remote firewall.
