Running GWN Manager

Before running GWN Manager services, you will need to add firewall exceptions (only for CentOS7 and AlmaLinux9) using the following commands:

firewall-cmd –zone=public —
add-port=8443/tcp -–permanent
firewall-cmd –zone=public —
add-port=10014/tcp -–permanent
firewall-cmd –reload

CentOS/AlmaLinux – Adding Firewall exceptions

By default, GWN Manager uses port 8443 for the web service (Nginx) and port 10014 for gateway communication separately.

Run the script to start the services using the below command:

/gwn/gwn start

Starting GWN services

Information:
Starting version 1.0.20.22.23, GWN Manager service will start automatically after rebooting the Linux host machine.

After all services start up, please go to the Web Portal for further configuration. By default, the Web Portal address is:
https://server_ipaddress:8443

In our case it will be as follows:

Configuring GWN Manager
Users can change the Nginx binding protocol, port as well as the access address for communication (You do not need to change the default settings in general).

/gwn/gwn config

If you change the Nginx binding port, you will need to add a new firewall Exception. Moreover, for security considerations, GWN Manager runs as a non-root user, so please consider using a number larger than 1024 as the Nginx binding port number, or the service may fail to start due to denied permission.
HTTPS is used by default due to its security, and GWN Manager will automatically generate a certificate along with the private key after installation. You can also apply for a certificate signed by a trusted authority to replace it.
Below system paths are where you can replace the SSL certificate and private key

certificate:
/gwn/conf/nginx/s
sl.pem private key:
/gwn/conf/nginx/ss
l.key

After replacing the two files, restart the GWN service to validate the configuration change:

/gwn/gwn restart

Restarting GWN services

Information:
Starting version 1.0.20.22.23, GWN Manager service will start automatically after rebooting the Linux host machine.

Important Notes

GWN Manager only supports one access address at present, so if your machine has more than one network interface, you should set the access address to the one (IP address) that you expect to communicate with the Access point.
Please consider setting the right time zone of your machine before running GWN Manager, modifying the time zone may cause data corruption.
