Ntop is a web-based Graphical, Network Traffic Monitoring Tool, NTop shows network usage on real time, a web browser can be used to manage and navigate through Ntop traffic information to better understand network status. Among other things, Ntop monitors, report hosts traffic and supports the following  protocols:

  • TCP
  • UDP
  • ICMP
  • SNMP
  • (R)ARP
  • IPX
  • DLC
  • Decnet
  • HTTP
  • Netbios

The  installation of Ntop is a pretty simple task. It can easily installed on linux 5.x/6.x using yum command, but first you need to install the EPEL Repository (Extra Packages for Enterprise Linux Repository), applicable to your Operating System architecture 32bit or 64bit (if already not installed) by using the following commands (make sure, you must be root user):
Install EPEL RPM for CentOS 6.x
32-BIT

# wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
# rpm -ivh epel-release-6-8.noarch.rpm

64BIT

# wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
# rpm -ivh epel-release-6-8.noarch.rpm

Install EPEL RPM for CentOS 5.x
32-BIT

# wget http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
# rpm -ivh epel-release-5-4.noarch.rpm

64BIT

# wget http://download.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm
# rpm -ivh epel-release-5-4.noarch.rpm

Once the repository is installed, all you need to do to install Ntop in CentOS using the following commands:
Install NTop

# yum install ntop
# ntop

here  the ntop monitoring logs will start-up on command prompt and it will ask for the admin password, set the password of “admin” user for future use. After the installation of Ntop is complete, now open the web browser to start monitoring using the NTop as mentioned below:
http://localhost:3000
or
http://192.168.1.10:3000
