Gosh: Server Listens On Wildcard Interface

Attention

To let the NSA in, the default config lets everybody in. This is bad. Big fat minus!

# netstat -antp
...
tcp6       0      0 :::3000                 :::*                    LISTEN      384735/grafana
...

In the /etc/grafana/grafana.ini, find the following line:

# The ip address to bind to, empty will bind to all interfaces
;http_addr =

and change it to

http_addr = 127.0.0.1

Restart

# systemctl restart grafana.service

Better

# netstat -antp
...
tcp        0      0 127.0.0.1:3000          0.0.0.0:*               LISTEN      388016/grafana
...

Most if not all functionality is available through http://localhost:3000. Based on a plugin system, many plugins are available through the base installation. Other plugins might be needed; even MQTT is available initially, though.
