Ntop is an open-source and very useful network-monitoring tool that displays a list of hosts that are currently using the network and reports information concerning the IP traffic generated by each host. You can use a web browser to monitor your network traffic, connections and bandwidth usage. Ntop monitors and reports host traffic and supports various protocols like TCP/UDP/ICMP, IPX, ARP, DLC, Decnet, AppleTalk, and Netbios.
In this tutorial I will explain how to install and configure Ntop on Ubuntu 14.04.
Installing Ntop
You can install ntop by running the following command:
sudo apt-get install ntop
During installation you will be asked to enter the password for the administrator. Simply enter your password and finish installation.
After installing ntop, start ntop service:
sudo /etc/init.d/ntop start
By default, ntop listens on port 3000 to display network usage via a web browser.
To verify ntop is working, run:
sudo netstat -tulpn | grep :3000
You should see an output like the following:
View Ntop
You can see the ntop web interface by typing the url http://your-server-ip:3000 on your web browser.
The ntop screen has the following main menus:
- About: what are ntop, credits, documentations and configurations.
- Summary: traffic, hosts, network load, network flows
- All protocols: traffic, throughput, activity
- IP: summary, traffic directions, local
- Utils: data dump, view log
- Plugins: many plugins to enable or configure
- Admin: configure, shutdown
You can see a screenshot of some menus in the following images.
1. Ntop Configuration
You will see the version of ntop, name of operation system and date of ntop configuration.
2. Global Traffic Status
You will see the number of the network interface with IP address and global network traffic statistics.
3. Host Information
You will see the information of your host system like hostname, IP address, MAC address, DNS and your real IP address.
4. Network Load Statistics
You will see your network load statistics of the last ten minutes, last hour, last day and last month.
Conclusion
After installing Ntop, you can easily monitor your network usage, network load and network traffic in real time. Feel free to leave a comment if you have any questions.

I will do a test of the Ntop where I work. This can be very useful.
Thanks
I tried to config. ntop, but it asked for username and password. When I enter my root user and pass it did not accept it.
I tried with my other username and pass ditto. Is there a special username and pass for ntop?
Thanks.
Yes you must use the root username and password.

You need to give password of admin user during ntop installation.
You can install ntopng similar to ntop on your windows 7 pc
Hey, Perform this
apt-get –purge remove ntop
apt-get install ntop
while installing it will ask for interface, provide interface detail as eth0, wireless
one clicked ok it will ask for admin password for ex: admin123, enter the password you want to set for admin user of ntop
Once done, try logging into the ntop with credentials as user:admin & password:admin123 and you should be able to log into ntop now.
I’ve installed ntop on my vps. Anyone can access it without my permission. Do you know how to secure whole ntop web interface? I mean ip:3000.
Hi, i hope you still running this website. I want to ask. The installation is successful. But somehow after 3 days it takes all HDD space on my server.
I want to ask a question
1. Is there any way to filter kind of traffic to save?
2. Is there a way to see those traffic in cmd? i use ubuntu server 14.04
Thank you!
