[Iftop-users] [PATCHES] Connection tracking map & multi-interface monitoring

[Luke Dashjr]

First patch looks up connections in Linux's connection tracking (NAT) table.
Handy to iftop the WAN interface on my router and still see LAN IPs.

Second series (4 patches) enables combining multiple network interfaces.
I'm using this to monitor my real WAN plus inside-a-VPN traffic (and a filter 
rule to exclude the VPN traffic on the real WAN).

(It would have been nicer to take multiple -i options rather than use a comma 
separator, but the options code was too messy and I didn't care to spend 
additional time figuring out how to refactor it.)
