Xprobe2 is a remote active operating system fingerprinting tool.
Xprobe2 uses advanced technics, such as the usage of fuzzy logic
to match fingerprinting results with the tool's signature database,
unique fingerprinting methods and other, to provide with accurate
results.

Xprobe2 has evolved from the original Xprobe tool, but it has been
completely rewritten from scratch in C++.



License
-------
Xprobe2 is distributed under GNU license. See COPYING for more details.

The fingerprinting database is is available for free use by open source 
software under the terms of the GNU General Public License.

For commercial usage please contact: ofir@sys-security.com
    
        
Requirements
------------

- A C++ compiler. (gcc will do)

- libusi++ (included with the distribution)

- lipcap (use version 0.6.x or later)
  If libpcap is not installed in standard path, use --with-libpcap-libraries=/path/ 
  and --with-libcap-includes=/path options.


Supported platforms
-------------------

The tool has been succesefully compiled and tested under the following platforms:

FreeBSD 4.x, 5.x 
Linux 2.0.x, 2.2.x, 2.4.x
Solaris 2.x
OpenBSD 2.x, 3.x
NetBSD 1.4.x, 1.5.x, 1.6.x
IRIX (with SGI freeware libpcap, http://freeware.sgi.com/, naitive SGI compiler).


Platforms which we are able to fingerprint
------------------------------------------

see etc/xprobe2.conf


How to install
---------------

tar xvfz xprobe2-{release}.tar.gz
cd xprobe-{release}
./configure
(or ./configure --with-libpcap-libraries=/usr/local/lib --with-libcap-includes=/usr/local/include)
make
make install

send complains to fygrave@tigerteam.net if the compilation breaks. (use
--enable-debug to track/report errors)


How to use:
-----------

See manual for details or use the -h command line to list available options.


Architecture
------------

Xprobe2 consists of 2 major parts: core fingerprinting engine which
includes fuzzy signatures matching engine, signatures processing,
and is generally intrefacing between the modules, and tests, which
are presented as (extrenal) dynamically loadable shared modules.

Core module has no idea about the signatures nor how they are being
applied to received packets. Please see fuzzy_fingerprinting paper in
docs for details.    

Xprobe2 modules are supposed to provide routines for signature element
parsing for each module, module names, initialization routines, module
execution routines, module deinitialization signatures and other
specific information. Please see docs/modules_howto.txt for details.
