Your system is now updated with the repositories needed for installation. Now go to the default ntopng.conf configuration file using a vim editor and add the following contents in the file.

root@linuxhelp1:~# vim /etc/ntopng.conf
 This configuration file is similar to the command line, with the exception
# that an equal sign ' ='  must be used between key and value. Example: -i=p1p2
# or --interface=p1p2 For options with no value (e.g. -v) the equal is also
# necessary. Example: " -v="  must be used.
#
# DO NOT REMOVE the following option, required for daemonization.
-e=
# * Interfaces to sniff on: one interface per line, prefix with -i=
# E.g.
-i=ens33
#-i=wlan0
# If none is specified, ntopng will try to auto-detect the best interface.
#
# * Port on which ntopng will listen for the web-UI.
-w=3000

Restart the ntopng service by triggering the following command.

root@linuxhelp1:~# systemctl restart ntopng

You can also update the Firewall by executing the following allow command.
