Install NTOP NG on CENTOS 6

1. download latest epel-release and install

yum -y install http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

2. Create a repository for NTOP.

vi /etc/yum.repos.d/ntop.repo 

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

3.  
[epel]
name=Extra Packages for Enterprise Linux X - $basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-X&arch=$basearch
failovermethod=priority
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-X

and

# cd /etc/yum.repos.d/
# wget https://copr.fedoraproject.org/coprs/saltstack/zeromq4/repo/epel-X/saltstack-zeromq4-epel-X.repo 

 Note: replace X with 6 (for CentOS 6) or 7 (for CentOS 7)
then do:

yum erase zeromq3 (Do this once to make sure zeromq3 is not installed)

yum install zeromq 

yum clean all

yum update 

yum install pfring n2disk nprobe ntopng ntopng-data nbox

 *Note: At this point I had a Transaction Check error because my kernel 
was newer than what the ntop compile expected, so I had to install an 
older kernel for the yum install to complete. If the above completes 
without an error you can skip this step, else grab the older kernel and 
try the package install again.

 yum -y install kernel-2.6.32.431.20.3.el6 

edit config file: 

  vi /etc/ntopng/ntopng.start 

  --local-networks "192.168.0.0/24"

vi /etc/sysconfig/iptables

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