Re: [Iftop-users] Forwarded bug reports from Debian

Markus,

Thanks for passing this on. These all sound like reasonable suggestions, which I'll consider when next working on iftop.

There's a couple where I'd be grateful for pointers from anyone on the list about how to implement (even more grateful for patches!)

1. iftop does not notice changes to ppp interfaces and stops refreshing its output http://bugs.debian.org/543138

Does anyone know how to detect when this happens? It's obviously not treated as an error by pcap_loop() when it happens.

2. iftop: chooses eth0 as the default interface instead of the default route http://bugs.debian.org/644998

The code could be changed in two ways:

• Only consider interfaces with routes associated with them.
• Prefer the interface with a default route to other ones.

This is a great idea, but what's the easiest way to identify these interfaces programmatically?

5. NAT support http://bugs.debian.org/631682

One user asked for NAT support for using iftop on a router to monitor traffic.

Is this feasible? I'm not sure how I'd go about trying to un-NAT a packet for display.
