You can do this by running following command: sudo firewall-cmd -permanent -add-port=3000/tcp Ntopng listens by default at the 3000 TCP port so you’ll need to add firewall rule to access ntopng from remote machine. Save and exit the file, restart ntopng and check status again: sudo systemctl restart ntopng You can remove this warning message by editing the ntopng configuration file: sudo nano /etc/ntopng/nfĪdd/change the line shown below: -G=/var/tmp/ntopng.pid\ To check the ntopng status, run: sudo systemctl status ntopng However if you check the status, you’ll see that ntop gives you a "No Pro licence is found" error, and announces that it will return to community mode after 10 minutes. Ntop will create a default configuration file at /etc/ntopng/nf. Let’s start ntopng and add the service to start at boot time: sudo systemctl start rvice Now, start the redis service and enable the service to start at boot time: sudo systemctl start rvice
#Ntopng install install#
sudo yum -enablerepo=epel install hiredis-devel Once ntopng has been installed, you need to install the hiredis-devel package and start the redis server before starting ntopng.
#Ntopng install update#
Now, update the repositories and all installed packages with the following command: sudo yum -y updateįinally, install ntopng by running the following command: sudo yum -enablerepo=epel install redis ntopng sudo nano /etc//ntop.repoĪdd the following content to the ntop.repo file: To do this, create a file named ntop.repo inside the /etc// directory. Next, you will need to create an ntop repository for the stable builds. To begin, you will need to add the EPEL repository to your system by running the following command: sudo yum install epel-release
Ntopng is not available in the default CentOS 7 repository. Support for sFlow, NetFlow and IPFIX through nProbe.Protocol-level real-time analysis of local network traffic.
