| Summary : A system-independent interface for user-level packet capture
|
Description :
The libpcap is a system-independent interface for user-level packet capture.
libpcap provides a portable framework for low-level network monitoring.
Applications include network statistics collection, security monitoring,
network debugging, etc. Since almost every system vendor provides a different
interface for packet capture, and since we\'ve developed several tools that
require this functionality, we\'ve created this system-independent API
to ease in porting and to alleviate the need for several
system-dependent packet capture modules in each application.
For some platforms there are README.{system} files that discuss issues
with the OS\'s interface for packet capture on those platforms, such as
how to enable support for that interface in the OS, if it\'s not built in
by default.
The libpcap interface supports a filtering mechanism based on the
architecture in the BSD packet filter. BPF is described in the 1993
Winter Usenix paper ``The BSD Packet Filter: A New Architecture for
User-level Packet Capture\'\'. A compressed PostScript version can be
found at

or

and a gzipped version can be found at

A PDF version can be found at
http://www.tcpdump.org/papers/bpf-usenix93.pdf
Although most packet capture interfaces support in-kernel filtering,
libpcap utilizes in-kernel filtering only for the BPF interface.
On systems that don\'t have BPF, all packets are read into user-space
and the BPF filters are evaluated in the libpcap library, incurring
added overhead (especially, for selective filters). Ideally, libpcap
would translate BPF filters into a filter program that is compatible
with the underlying kernel subsystem, but this is not yet implemented.
