Re^2: Network interface discovery

That sounded ideal, but sadly my Net::Pcap does not define findalldevs, although it is present in libpcap:

$ perl -MNet::Pcap -e 'Net::Pcap::findalldevs()'
Can't locate auto/Net/Pcap/findalldevs.al in @INC 

$ perlver Net::Pcap
0.04

You could try a newer version of Net::Pcap; the documentation on CPAN says this function is supported in 0.05.	[reply]

Interesting.. CPAN fed me the 0.04 version. Anyway, 0.05 is getting there, although the function only returns the network names, and Net::Pcap::lookupnet() returns the network, not the address.. e.g. for 127.0.0.1 it returns 127.0.0.0. So it's not quite what I needed, but thanks for the pointer. I'll keep digging..	[reply]

Ah, you're right. The version of `findalldevs` in `libpcap` actually returns the addresses of the interfaces, along with their names. Probably you could modify the Net::Pcap module to provide this information, or get at it using Inline::C.	[reply] [d/l]
