Comments on Monitor Network Traffic with Ntopng on Ubuntu 18.04 LTS

This demo version last only 6min and 30 seconds (yes you read well)

After that you are kicked out of the server and are required to provide a professionnal licence.

The repositories do not work:

E: The repository 'http://ppa.launchpad.net/elementary-os/testing/ubuntu bionic Release' does not have a Release file.

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

N: See apt-secure(8) manpage for repository creation and user configuration details.

E: The repository 'http://packages.ntop.org/apt-stable/5.0 x64/ Release' does not have a Release file.

Works fine here, just tested it on a fresh Ubuntu 18.04 LTS server:

 

root@server1:~# sudo dpkg -i apt-ntop.deb

Selecting previously unselected package apt-ntop.

Reading package lists... Done

Freshly installed Ubuntu Server 18.04.1 and "sudo apt-get install pfring-dkms nprobe ntopng n2disk cento -y" generated this error:

Solution for previous fail:

I had to add repository universe to the /etc/apt/sources.list.$ sudo su# vi /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu/ bionic main universe deb http://archive.ubuntu.com/ubuntu/ bionic-security main universe deb http://archive.ubuntu.com/ubuntu/ bionic-updates main universe

save and close

# apt-get update

 

many many thanks! it works perfectly!

Thanks Hitesh -- easy to follow instructions, works really well (presently living as an expat, so useful to be able to monitor my Linux box at home). 

I installed well enough that the web page came up, prompting me for Username and Password. When I entered "admin" in both fields, the page redrew with no change. Not sure what this means. The install instructions don't say what IP addresses you have to add, so I only added "lo". Is this a problem? I mean, in order to monitor an interface, do I have to specify it (or a range that contains it) in the .start file? Even if you think this is obvious, it's probably worth stating explicitly.

Actually I misremembered. I did enter my machine's local IP address (10.8.8.8/24) in the .start file.  And the "lo" interface in the .conf file.  Should I get something other than a redraw of the login prompt?
