+# Port allocation
+
+The `ports_manager` library handles the low-level port allocation storage.
+It registers and stores UDP and TCP port information in a SQLite database
+for the local node within the cluster.
+
+The SQLite database file, `ports.sqlite`, is stored in the node's `state/`
+directory. To inspect its contents, use the following command:
+
+    podman run -i --rm --volume /var/lib/nethserver/node/state/ports.sqlite:/srv/ports.sqlite:z alpine ash -c 'apk add sqlite ; sqlite3 /srv/ports.sqlite' <<<"SELECT *, 'tcp' FROM TCP_PORTS UNION SELECT *, 'udp' FROM UDP_PORTS;"
+
+For more information, refer to [Port
+allocation](../../modules/port_allocation) under the Modules section.

 To use the `ports_manager` library, you need to import it into your Python script as follows:

+These actions can be carried out using the agent library without making
+direct node API calls, as explained in the next section.

 ## Agent library
 
 The Python `agent` library provides a convenient interface for managing port allocation and deallocation, based on the node actions `allocate_ports` and `deallocate_ports`.
 
 It is optional to specify the `module_id` when calling the port allocation or deallocation functions. By default, if the `module_id` is not provided, the function will automatically use the value of the `MODULE_ID` environment variable. This simplifies the function calls in common scenarios, ensuring the correct module name is used without manual input. However, if needed, you can still explicitly pass the `module_id`.
+Note that only the cluster agent can modify the port allocations of other modules.
