ntopng on CentOS 6

Ensure you have the EPEL repository installed first then do the following to add a repository for ntopng:

vi /etc/yum.repos.d/ntop.repo

Add the following (the deri bit at the end below is not cut off – it works):

[ntop]
name=ntop packages
baseurl=http://rpm.ntop.org/$releasever/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://www.nmon.net/centos/RPM-GPG-KEY-deri

Install ntopng and dependencies:

yum install pfring n2disk nProbe ntopng ntopng-data

Set the services to auto start on boot:

chkconfig redis on
chkconfig ntopng on

Ensure the GeoIP databases are oresent:

cd /usr/local/share/ntopng/httpdocs/geoip
ls

If the GeoIP files are not there you will want to download them from maxmind.

Next move to the ntopng configuration directory:

cd /etc/ntopng

Edit the start file:

vi ntopng.start

Amend it with the details for your own network e.g.

--local-networks "192.168.124.0/24"
--interface 0

Next copy the sample config file:

cp ntopng.conf.sample ntopng.conf

and edit it:

vi ntopng.conf

I changed the .gid to .pid for consistency:

-G=/var/tmp/ntopng.pid

Start the services:

service redis start
service ntopng start

Use netstat to ensure that ntopng is listening on port 3000:

netstat -luntap | grep 3000

add a line for IPTables to allow access to the web interface:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 3000 -j ACCEPT

View the web interface:
http://www.domainname.com:3000
