Baffle

Baffle is a tool for actively fingerprinting and identifying wireless devices. See ./tool --help for options.

Compiling

Because we need to be able to sniff and inject arbitrary 802.11 packets, we need help from a few C-libraries (see Depedencies). Before running Baffle, you must compile the Ruby extensions wrapping these libraries. Generally, it it done in the following manner:

$ ruby extconf
$ make

You will need to run these commands in the following directories:

  • ./lib/capture/
  • ./lib/ruby-lorcon/

Linalg depends on LAPACK, a fortran linear algebra package, and on f2c, a fortran to C bridge. These can typically be installed from package management systems or compiled from source. The ruby linalg library itself is compiled with the following commands:

$ ruby install.rb configure
$ ruby install.rb make
$ sudo ruby install.rb install

Once those dependencies are met, everything should work fine.

Depedencies

  • C-libraries

    • lorcon
    • libpcap

  • Fortran libraries

    • LAPACK

  • Ruby libraries

    • linalg (depends on the LAPACK fortran library and f2c library)
