Using the stable from the official ntop package:
Instructions can be found at http://packages.ntop.org/apt-stable/
Visit http://localhost:3000, login as admin for the username and password.
ntop can be a resource hog, you can run out of RAM depending on the number of interfaces that you are monitoring. I would suggest that you edit the file: /etc/ntopng.conf and add only the interfaces that you need to monitor.
$ sudo nano /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=eth0
-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
For some reason, apt does not detect the newer ntopng package from ntopng.org. I will be reporting this as a bug.
