libtins is a high-level, multiplatform C++ network packet sniffing and crafting library.

Its main purpose is to provide the C++ developer an easy, efficient, platform and endianess-independent way to create tools which need to send, receive and manipulate specially crafted packets.

libtins depends on libpcap and openssl, although the latter is not necessary if some features of the library are disabled.

In order to compile, execute:

# Create the build directory
mkdir build
cd build

# Configure the project. Add any relevant configuration flags
cmake ../

# Compile!
make

Note that by default, only the shared object is compiled. If you would like to generate a static library file, run:

cmake ../ -DLIBTINS_BUILD_SHARED=0

The generated static/shared library files will be located in the build/lib directory.

libtins is noticeably faster if you enable C++11 support. Therefore, if your compiler supports this standard, then you should enable it. In order to do so, use the LIBTINS_ENABLE_CXX11 switch:

cmake ../ -DLIBTINS_ENABLE_CXX11=1

The TCP ACK tracker feature requires the boost.icl library (header only). This feature is enabled by default but will be disabled if the boost headers are not found. You can disable this feature by using:

cmake ../ -DLIBTINS_ENABLE_ACK_TRACKER=0

If your boost installation is on some non-standard path, use the parameters shown on the CMake FindBoost help

If you want to disable WPA2 decryption support, which will remove openssl as a dependency for compilation, use the LIBTINS_ENABLE_WPA2 switch:

cmake ../ -DLIBTINS_ENABLE_WPA2=0

If you want to disable IEEE 802.11 support(this will also disable RadioTap and WPA2 decryption), which will reduce the size of the resulting library in around 20%, use the LIBTINS_ENABLE_DOT11 switch:

cmake ../ -DLIBTINS_ENABLE_DOT11=0

Once you're done, if you want to install the header files and the shared object, execute as root:

make install

This will install the shared object typically in /usr/local/lib. Note that you might have to update ldconfig's cache before using it, so in order to invalidate it, you should run(as root):

ldconfig

You may want to run the unit tests on your system so you make sure everything works. In order to do so, you need to follow these steps:

# This will fetch the googletest submodule, needed for tests
git submodule init
git submodule update

mkdir build
cd build

# Use any options you want
cmake .. 

# Compile tests
make tests

# Run them
make test

If you find that any tests fail, please create an ticket in the issue tracker indicating the platform and architecture you're using.

You might want to have a look at the examples located in the "examples" directory. The same samples can be found online at:
