The following is a ruby wrapper for libpcap, which I believe is what  
Wireshark uses to capture packets:

Note: there might be newer versions out there.

I should have added that most links are broken on the page I sent  
earlier, just get the tarball. It has the code and the samples.

Hope that helps,
