Exercise 63: Louisiana Fishing


Network traffic can be monitored in a number of ways. For Louisiana Fishing, one of the best approaches is to use ntop. The following steps install this utility and illustrate its usage:

1.

Log in as root and start YaST.

2.

Choose Software and then Install and Remove Software. Search for ntop and choose to install the package.

3.

Exit YaST upon completion of the installation.

4.

Open a terminal session and type rcntop start to start the ntop daemon.

5.

A message will appear stating that the administrator password has not yet been set. Type ntop A u wwwrun.

6.

Enter a password for the administrative user. Reenter the password when prompted. Check to see if ntop is running (ps ef | grep ntop). If not, repeat the command in step 4.

7.

Open Konqueror and go to http://localhost:3000 as shown in Figure 4.64.

Figure 4.64. Access ntop through the browser.


8.

On the first line of ntop, select All Protocols.

9.

On the second line, select Traffic, and you will see a summary of all traffic that has occurred since the program has been running. Select Throughput and Activity to gather statistics on those items.

10.

You can log the data (Admin, Log), and shut down ntop (Admin, Shutdown) from this interface as well.
