Hi!

I want to work with the pcap library, and I installed libpcap and pcap
library in Ubuntu, but when I try a code, there is an error:

/usr/lib/ruby/1.8/pcaplet.rb:51:in `lookupdev': no suitable device found
(Pcap::PcapError)
        from /usr/lib/ruby/1.8/pcaplet.rb:51:in `initialize'
        from httpsniff.rb:4:in `new'
        from httpsniff.rb:4

I searched but i didnt find what to do (I've already required the
library...)

Thanks, and sorry for my english ^^
