So,
I have an interface, eth1, that is used for pppd (connects direct to the modem) that is used to create the ppp0 virtual interface. When using iftop on ppp0, it works great. Sadly sometimes that interface bounces, and iftop stops reporting data after it comes back up. When trying to use iftop on eth1, no data is reported even when ppp0 is up. Can we get iftop to work on ppp0? I hope I explained it well...thank you!

...Ok.
iftop -i ppp0 : I get good data iftop -i eth1: I get nothing

Does iftop exit when the PPP connection drops or does it stay up but never report anything again?

Stays up, but never reports anything. Frankly I don't blame it since....you know.....the interface it was monitoring just vanished 😉

That's curious..might be worth a look at the tcpdump source code because, when an interface drops or disappears, it exits...if iftop did that, you could just put it into a loop to start again. Maybe try running tcpdump on the interface to verify that it exhibits the behavior in your situation so we can know we're on the trail of a possible workaround.
