I tried the ntop install. Everything works fine but ClearOS's content filter blocks ntop. I tried unblocking the IP address but content filter doesn't allow IP address.
This is the error I get:
The content filter has blocked the page that you have requested.
Content Filter Warning
Web Site Address linkhelp.clients.google.com/tbproxy/lh/fixurl?hl=en-U
Description Banned URL -- google.com/tbproxy
If someone could share on this, that would be great.
