Connecting the TLP system

Follow this procedure to add the Total Lightning Processor system to the IRIS Focus system to retrieve lightning data.

These steps are typically done automatically by the ./rsw-installer script when you include the --lightning option. You only need to perform these steps if you did not include the --lightning option when running ./rsw-installer. Otherwise, you can skip to section Configuring the TLP for IRIS Focus.

To enable lightning in the Web application, edit the vsoweb-override.ini configuration file in the /etc/vaisala/radarsw/configuration directory. Change (or create, if not present) the [PROVIDERS] section to the following:
```
[PROVIDERS]
radar.enabled = true
lightning.enabled = true
```

Restart the Web application by typing:

systemctl restart vaisala-radarsw-webapp

Configure the firewall.
The Total Lightning Processor connects to the Kafka data broker on port 9094 on the IRIS Focus system. If you are running the firewalld service, configure the firewall to allow this connection.

Example: If the TLP system IP address is 10.55.11.2, run the following firewall commands on the IRIS Focus system to allow 10.55.11.2 access to port 9094:
```
firewall-cmd --permanent --zone=public --add-rich-rule='rule family="ipv4" source address="10.55.11.2/32" port protocol="tcp" port="9094" accept'

firewall-cmd --reload
```
Configure the Total Lightning Processor.

At this point, the IRIS Focus system should be set up and ready for lightning data provided by the Total Lightning Processor. Follow the instructions in Configuring the TLP for IRIS Focus to start the flow of lightning data from the TLP to IRIS Focus.
