Thanks for the reply! Unfortunately, no. IIUC, P prevents further updates to the display and 'o' prevents the addition of additional sources / destinations - so again, static.

I would like iftop to function exactly the way it does now except I don't want any of the generated lines to disappear / fade from the main display until I manually clear the screen.

The motivation behind this request is that I would like to leave iftop running and be able to return to it several hours / days later and be able to see all of the connections and traffic that occurred while away. With the current options, I'll only be able to see this information for connections that were active the entire time.

I understand iftop is designed to be a *real-time* monitor so any advice you could give would be appreciated. I believe the new 'output to text' parameter may help but I'm not so sure how to go about implementing that. Thanks!
