libnet-pcap-perl - 0.21-2+b1 main

Net::Pcap allows the user to interface with the LBL pcap(3) library.
Libpcap describes itself as "a system-independent interface for user-level
packet capture. Libpcap provides a portable framework for low-level network
monitoring." This modules gives a program the ability to capture data from a
network interface in a similar way tcpdump does.
