Running Ntop Guide

This is a quick guide to getting ntop (network top - http://www.ntop.org) running on your system. Ntop will check all incoming and outgoing traffic on your HDA, giving you nice graphs and metrics.

First you need to install ntop:

 root@localhost# yum install ntop 

To run it you type:

 root@localhost# service ntop start 

To view the statistics gathered by ntop:

 http://hda:3000 

or secure:

 https://hda:3001 


Below you can find a sample configuration file for ntop:


 # tells ntop the user id to run as 
 --user ntop 
 #save messages into the system log 
 --use-syslog=daemon 
 # sets the directory that ntop runs from 
 --db-file-path /var/lib/ntop 
 # the amount and severity of messages that ntop will put out 
 --trace-level 3 
 # limit ntop to listening on a specific interface and port 
 --http-server 3000 --https-server 3001 
 # specify the interface 
 --interface eth0 
 # Under certain circumstances, the sched_yield() function causes the ntop web 
 # server to lock up.  It shouldn't happen, but it does.  This option causes 
 # ntop to skip those calls, at a tiny performance penalty. 
 --disable-schedyield 
 # disables "phone home" behavior 
 --skip-version-check=yes 

Troubleshooting:
You might need to set a password for ntop before you can access certain parts of the admin panel of ntop. You can set the initial password as described below:

 root@localhost# service ntop stop 
 root@localhost# ntop -A 
 <fill in a password> 
 root@localhost# service ntop start
