Netflow Collector Ubuntu With Ntop Stage 2



We will go straight to into the subject, because I explained about the NTOP is already a bit on the first stage, now we resume his article, because there are more ways to do the one Install NTOP on ubuntu linux, so you don't have to worry about running out of the way, as a linux user it should should not be run out of the way, let's take a look below:

How to installation
The installation, I use the GNU/Linux operating system Kernel 3.2.5.0 -35 Distro Ubuntu 12.04-1.
The installation steps are as follows:
 
Install ntop with the type command in your linux terminal:
sudo apt-get install ntop -y

Add dependency ntop with the command:
sudo apt-get source ntop

Install the RSS tools to add a plugin, so the ntop can display Network load stats with the command:
sudo apt-get install rrdtool-tcl rrdcollect

Make changes to permissions, type the commands at the terminal as below:


sudo chmod chown -Rf ntop.root/var/ntop/rrd
sudo chown -Rf ntop.root/var/ntop/rrd

To run the Ntop services type commands in terminal:
sudo service ntop start

Then to run Ntop in the browser, type the address in the address bar: http://<serverip>: 3000

ServerIP, if we use it on localhost then it can be replaced with localhost, if Ntop installed on servers/devices with a specific ip, then use that IP.

Here are a few screenshots of the ntop that I run, and can monitor the network wifi on campus:








Excess Ntop:
  • NTOP in design hybrid, so the Ntop can perform packet data analyzer in layer 2 and layer 3.
  • NTOP get data on layer2, which could mean another protocol or ethemet. Besides ethemet, ntop can also work with FDDI, PPP, token ring, and RAW. This protocol list continues to grow as his version continues to get a revision of the community.
  • NTOP has support for IPv6.
Shortage Of Ntop:
  • Can only monitor in 1 subnet only, if you want to monitor other subnet, then it must be in the configuration of the first.
  • The selection interface which will be monitoring the road should first we dedicate it manually.
