Installing ntop on Mac OS X 10.5.x, Leopard
First off, install MacPorts, with some additional instructions here.
Then open up the Terminal (/Applications/Utilities/Terminal.app) and type:
sudo port install ntop
Notice: It will take a LONG time even on good hardware (about 10 minutes on my Mac Pro with a striped RAID boot array).
After that is complete, you can then launch it by running:
sudo ntop -d
which launches it in daemon mode so that you can close your terminal and still have it running in the background.
It should prompt you to enter the admin password, which has to be 5 characters or more. Type it again to confirm, and it should launch.
Notice that if you do not run it with sudo, you may receive this message:

It’s just telling you that it does not have the proper permissions to run in the /opt/local/var/ntop/prefsCache.db database.
Go to a web browser, and type:
http://localhost:3000
and you should be able to see an interface something like the following:
