====== Installing Aircrack-ng from Source ======

Legacy information can be found [[install_aircrack_old|here]].

===== Requirements =====

  * Autoconf
  * Automake
  * Libtool
  * shtool
  * OpenSSL development package or libgcrypt development package.
  * pkg-config

==== Linux ====

  * Airmon-ng requires ethtool and rfkill
    * If USB bus is present, lsusb
    * If PCI/PCIe bus is present, lspci
  * LibNetlink 1 (libnl-dev) or 3 (libnl-3-dev and libnl-genl-3-dev) development packages. It can be disabled by passing --disable-libnl to configure.
  * Kernel headers and gcc as well as make have to be installed on your system (build-essential on Debian based distributions)
  * make and Standard C++ Library development package (Debian: libstdc++-dev)

==== Windows (Cygwin) ====

  * w32api is required
  * if using clang, libiconv and libiconv-devel
  * make and Standard C++ Library development package

==== MacOS ====

Install the following via Homebrew (brew):

  * autoconf
  * automake
  * libtool
  * openssl
  * shtool
  * pkg-config
  * hwloc
  * pcre
  * sqlite3
  * libpcap
  * cmocka (optional)

==== FreeBSD, OpenBSD, NetBSD, Solaris ====

Install the following via pkg:

  * gmake
  * pkgconf
  * pcre
  * sqlite3
  * gcc9 (or better)

===== Optional stuff =====

  * If you want SSID filtering with regular expression in airodump-ng (-essid-regex) pcre development package is required.
  * If you want to use airolib-ng and '-r' option in aircrack-ng, SQLite development package >= 3.3.17 (3.6.X version or better is recommended)
  * If you want to use Airpcap, the 'developer' directory from the CD is required. It can be downloaded [[https://support.riverbed.com/content/support/software/steelcentral-npm/airpcap.html|here]].
  * For best performance on FreeBSD (50-70% more), install gcc5 via: pkg install gcc5 Then compile with: gmake CC=gcc5 CXX=g++5
  * rfkill
  * CMocka
  * hwloc: strongly recommended, especially on high core count systems where it may give a serious performance boost


===== Compiling and installing =====

Notes:
  * On OS X, *BSD and Solaris, use 'gmake' instead of 'make'.
  * In order to compile with clang instead of gcc, add 'CC=clang CXX=clang++' to the configure command.

==== Current version ====

   wget https://download.aircrack-ng.org/aircrack-ng-1.7.tar.gz
   tar -zxvf aircrack-ng-1.7.tar.gz
   cd aircrack-ng-1.7
   autoreconf -i
   ./configure --with-experimental
   make
   make install
   ldconfig

==== Compiling with AirPcap support (cygwin only) ===

  - Copy 'developer' directory from the [[airpcap|AirPcap]] CD at the same level as 'Aircrack-ng' directory
  - Append '- -with-airpcap=../developer' parameter to configure:

==== Compiling on *BSD ====

Commands are exactly the same as Linux but instead of **make**, use **gmake** (with **CC=gcc5 CXX=g++5** or any more recent gcc version installed).

==== Compiling on MacOS ====

Commands are exactly the same as Linux
==== Latest Git (development) Sources ====

**Note:** Compilation parameters can also be used with the sources from our git repository.

  git clone https://github.com/aircrack-ng/aircrack-ng
  cd aircrack-ng
  autoreconf -i
  ./configure --with-experimental
  make
  make install
  ldconfig

==== ./configure flags ====

When configuring, the following flags can be used and combined to adjust the suite to your choosing:

  * **with-airpcap=DIR**: needed for supporting airpcap devices on windows (cygwin or msys2 only) Replace DIR above with the absolute location to the root of the extracted source code from the Airpcap CD or downloaded SDK available online. Required on Windows to build besside-ng, besside-ng-crawler, easside-ng, tkiptun-ng and wesside-ng when building experimental tools. The developer pack (Compatible with version 4.1.1 and 4.1.3) can be downloaded at https://support.riverbed.com/content/support/software/steelcentral-npm/airpcap.html

  * **with-experimental**: needed to compile tkiptun-ng, easside-ng, buddy-ng, buddy-ng-crawler, airventriloquist and wesside-ng. libpcap development package is also required to compile most of the tools. If not present, not all experimental tools will be built. On Cygwin, libpcap is not present and the Airpcap SDK replaces it. See --with-airpcap option above. On debian based distro, install libpcap-dev

  * **with-ext-scripts**: needed to build airoscript-ng, versuck-ng, airgraph-ng and airdrop-ng. Note: Each script has its own dependencies. Note: It's only required in install phase.

  * **with-gcrypt**: Use libgcrypt crypto library instead of the default OpenSSL. And also use internal fast sha1 implementation (borrowed from GIT) Dependency (Debian): libgcrypt20-dev

  * **with-duma**: Compile with DUMA support. DUMA is a library to detect buffer overruns and under-runs. Dependencies (debian): duma

  * **with-xcode**: Set this flag to true to compile on OS X with Xcode 7+.

  * **disable-libnl**: Set-up the project to be compiled without libnl (1 or 3). Linux option only.

  * **without-opt**: Do not enable stack protector (on GCC 4.9 and above).

  * **enable-shared**: Make OSdep a shared library.

  * **disable-shared**: When combined with enable-static, it will statically compile Aircrack-ng.

  * **with-avx512**: On x86, add support for AVX512 instructions in aircrack-ng. Only use it when the current CPU supports AVX512.

  * **with-static-simd=**: Compile a single optimization in aircrack-ng binary. Useful when compiling statically and/or for space-constrained devices. Valid SIMD options: x86-sse2, x86-avx, x86-avx2, x86-avx512, ppc-altivec, ppc-power8, arm-neon, arm-asimd. Must be used with --enable-static --disable-shared. When using those 2 options, the default is to compile the generic optimization in the binary. **--with-static-simd** merely allows to choose another one.

  * **enable-maintainer-mode**: It is important to enable this flag when developing with Aircrack-ng. This flag enables additional compile warnings and safety features.

===== Troubleshooting Tips =====
==== error while loading shared libraries: libaircrack-ng.so.0 ====

Run **ldconfig** as root or with "sudo" to solve the issue.

==== "command not found" error message ====

After you do "make install" then try to use any of the Aircrack-ng suite commands, you get the error message "command not found" or similar.  Your system will look for the Aircrack-ng commands in the directories defined by the PATH command.

Normally, the Aircrack-ng suite programs and man pages are placed in:

   /usr/local/bin
   /usr/local/sbin
   /usr/local/man

On your system, to determine which directories have the Aircrack-ng programs enter the following. If using "locate" be sure to first run "updatedb".

   locate aircrack-ng
   locate airmon-ng

or

   find / -name aircrack-ng
   find / -name airmon-ng

Once you know the directories (exclude the source directories) then determine which directories are in your PATH. To see which directories are included in PATH on your particular system enter:

   echo $PATH

It should show something like:

   /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

At this point compare the actual locations with the directories in your PATH. If the directories are missing from your PATH then you have a few options:

  * Add the directories to your PATH.  See the one or more of the following web sites for details of how to do this:

   https://www.cyberciti.biz/faq/howto-print-path-variable/
   http://www.troubleshooters.com/linux/prepostpath.htm

  * Change to the particular directory with "cd" and then run the commands from within the directory. Don't forget to add "./" in front of each command.

  * Specify the full path for each command.  So if Aircrack-ng is located in the "/usr/local/bin" directory then run the command as "/usr/local/bin/aircrack-ng".

====== Installing pre-compiled binaries ======

===== Linux/BSD/OSX =====

With the exception of Linux penetration testing distributions, packages are usually out of date (MacOS is the exception). In this case, uninstalling the package and installing from sources is the recommended way to go.

On MacOS, install it is via [[https://www.macports.org/|Macports]] or [[https://brew.sh/|brew]]. Simply do "brew install aircrack-ng" or "sudo port install aircrack-ng"

===== Windows =====
The Windows version of the Aircrack-ng suite does not have an install program. You must manually install (unzipping archive) the software.

Here are the steps to follow for Windows:

  * Download the latest version of the Aircrack-ng suite for Windows to your computer. The link for the zip file can be found on the [[https://aircrack-ng.org|Wiki home page]].

  * Unzip the contents of the Aircrack-ng zip file into "C:\". This will create a directory called "aircrack-ng-1.6-win". This directory name will vary based on the exact version that you downloaded.  This main directory contains three subdirectories - "bin", "src" and "test".

Prior to using the software, make sure to install the drivers for your particular wireless card. See this [[install_drivers#windows|link]] for the instructions. We currently only support Airpcap; other adapters may be supported but require development of your own DLL so the different tools can interact with it.

To now use the Aircrack-ng suite, start Windows Explorer and double click on **Aircrack-ng GUI.exe** inside "bin" subdirectory.  The GUI requires .NET version 4.6.1 to run.

Alternatively, open a command prompt (Start menu -> Execute -> cmd.exe) and change to the  "C:\aircrack-ng-1.6-win\bin" directory and execute the individual commands.

**Important notes**:
  * [[airmon-ng|Airmon-ng]] is a Linux/FreeBSD tool only.
  * Remember that Windows only supports a limited subset of the commands.
