141: .SH "NAME"
142: libnet \- A C library for packet creation and injection
143: .SH "SYNOPSIS"
144: .IX Header "SYNOPSIS"
145: \&\fB#include <libnet.h>\fR
146: .SH "DESCRIPTION"
147: .IX Header "DESCRIPTION"
148: libnet is a packet assembly library that provides a portable interface for
149: packet creation and injection.
150: .PP
151: It is a high-level \s-1API\s0 that allows an application programmer to construct and
152: inject network packets. libnet provides a simplified interface for low-level
153: network packet shaping, handling and injection.
154: .PP
155: libnet hides much of the tedium of packet creation from the application
156: programmer such as multiplexing, buffer management, arcane packet header
157: information, byte-ordering, OS-dependent issues, and much more. libnet features
158: portable packet creation interfaces at the \s-1IP\s0 and link layer, as well as a host
159: of supplementary and complementary functionality. Using libnet, quick and
160: simple packet assembly applications can be whipped up with little effort. With
161: a bit more time, more complex programs can be written (\fBtraceroute\fR\|(8) and
162: \&\fBping\fR\|(8) were easily rewritten using libnet and \fBpcap\fR\|(3).
163: .PP
164: When building applications with libnet we recommend using \fBpkg\-config\fR\|(1) to
165: detect the precense and required version of libnet. The \fBlibnet\-config\fR\|(1)
166: script is still bundled in the libnet distribution, but is considered to be
167: deprecated in favor of \fBpkg\-config\fR\|(1). Both can be used to get compiler and
168: linker flags of the installed libnet library, as well as provide other useful
169: information. For applications using \s-1GNU\s0 autotools, we recommend using the
170: \&\s-1PKG_PROG_PKG_CONFIG\s0 and \s-1PKG_CHECK_MODULES\s0 m4 macros.
171: .PP
172: \&\fB\s-1NOTE\s0\fR: If you are writing your application with libnet, include \fIlibnet.h\fR,
173: which will include any additional header for you, rather than including
174: \&\fIlibnet/libnet\-functions.h\fR, \fIlibnet/libnet\-macros.h\fR or any of the others.
175: .SH "BACKWARDS COMPATIBILITY"
176: .IX Header "BACKWARDS COMPATIBILITY"
177: Your old code (circa libnet \fB1.0.x\fR) \s-1WILL NOT WORK\s0 with libnet> \fB>=1.1.x\fR.
178: See \fBdoc/MIGRATION.md\fR for easy steps on porting your old code.

182: .SH "AUTHORS"
183: .IX Header "AUTHORS"
184: The original author of libnet is Mike D. Schiffman.
185: .PP
186: libnet has been maintained and extensively enhanced since 2009 by Sam Roberts.
