Subject: Pcaplet 'lookupdev': no suitable device found

Hello,

I'm trying to prototype using Ruby for a networking class that I'm
taking, and I need to be able to use libpcap.  I found 'pcaplet' and
have been trying to get set up with that, but when trying to execute the
following line:

$network = Pcaplet.new('-s 1500')

I get the following 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 test.rb:3

I'm running on Ubuntu 6.10 under Microsoft Virtual PC 2007 as I don't
have Linux installed directly on my laptop.

Thanks in advance,
-Mike
