Summary: A system-independent interface for user-level packet capture
Name: libpcap
Version: %version
Release: 1
Group: Development/Libraries
License: BSD with advertising

%description
Libpcap provides a portable framework for low-level network
monitoring. Libpcap can provide network statistics collection,
security monitoring and network debugging. Since almost every system
vendor provides a different interface for packet capture, the libpcap
authors created this system-independent API to ease in porting and to
alleviate the need for several system-dependent packet capture modules
in each application.
Install libpcap if you need to do low-level network traffic monitoring
on your network.
