 * Note that the GPL places important restrictions on "derivative works",  *

 * misunderstandings, we interpret that term as broadly as copyright law   *

 * derivative work for the purpose of this license if it does any of the   *

 * following with any software or content covered by this license          *

 * ("Covered Software"):                                                   *

 *                                                                         *

 * o Integrates source code from Covered Software.                         *

 *                                                                         *

 * o Reads or includes copyrighted data files, such as Nmap's nmap-os-db   *

 * or nmap-service-probes.                                                 *

 *                                                                         *

 * o Is designed specifically to execute Covered Software and parse the    *

 * results (as opposed to typical shell or execution-menu apps, which will *

 * execute anything you tell them to).                                     *

 *                                                                         *

 * o Includes Covered Software in a proprietary executable installer.  The *

 * installers produced by InstallShield are an example of this.  Including *

 * Nmap with other software in compressed or archival form does not        *

 * trigger this provision, provided appropriate open source decompression  *

 * or de-archiving software is widely available for no charge.  For the    *

 * purposes of this license, an installer is considered to include Covered *

 * Software even if it actually retrieves a copy of Covered Software from  *

 * another source during runtime (such as by downloading it from the       *

 * Internet).                                                              *

 *                                                                         *

 * o Links (statically or dynamically) to a library which does any of the  *

 * above.                                                                  *

 *                                                                         *

 * o Executes a helper program, module, or script to do any of the above.  *

 *                                                                         *

 * This list is not exclusive, but is meant to clarify our interpretation  *

 * of derived works with some common examples.  Other people may interpret *

 * the plain GPL differently, so we consider this a special exception to   *

 * the GPL that we apply to Covered Software.  Works which meet any of     *

 * these conditions must conform to all of the terms of this license,      *

 * particularly including the GPL Section 3 requirements of providing      *

 * source code and allowing free redistribution of the work as a whole.    *

 *                                                                         *

 * As another special exception to the GPL terms, Insecure.Com LLC grants  *

 * permission to link the code of this program with any version of the     *

 * OpenSSL library which is distributed under a license identical to that  *

 * listed in the included docs/licenses/OpenSSL.txt file, and distribute   *

 * linked combinations including the two.                                  *

 *                                                                         *

 * Any redistribution of Covered Software, including any derived works,    *

 * must obey and carry forward all of the terms of this license, including *

 * obeying all GPL rules and restrictions.  For example, source code of    *

 * the whole work must be provided and free redistribution must be         *

 * allowed.  All GPL references to "this License", are to be treated as    *

 * including the terms and conditions of this license text as well.        *

 *                                                                         *

 * Because this license imposes special exceptions to the GPL, Covered     *

 * Work may not be combined (even as part of a larger work) with plain GPL *

 * software.  The terms, conditions, and exceptions of this license must   *

 * be included as well.  This license is incompatible with some other open *

 * source licenses as well.  In some cases we can relicense portions of    *

 * Nmap or grant special permissions to use it in other open source        *

 * software.  Please contact [email protected] with any such requests.       *

 * Similarly, we don't incorporate incompatible open source software into  *

 * Covered Software without special permission from the copyright holders. *

 *                                                                         *

 * If you have any questions about the licensing restrictions on using     *

 * Nmap in other works, are happy to help.  As mentioned above, we also    *

 * offer alternative license to integrate Nmap into proprietary            *

 * applications and appliances.  These contracts have been sold to dozens  *

 * of software vendors, and generally include a perpetual license as well  *

 * as providing for priority support and updates.  They also fund the      *

 * continued development of Nmap.  Please email [email protected] for further *

 * information.                                                            *

 *                                                                         *

 * If you have received a written license agreement or contract for        *

 * Covered Software stating terms other than these, you may choose to use  *

 * and redistribute Covered Software under those terms instead of these.   *

 *                                                                         *

 * Source is provided to this software because we believe users have a     *

 * right to know exactly what a program is going to do before they run it. *

 * This also allows you to audit the software for security holes.          *

 *                                                                         *

 * Source code also allows you to port Nmap to new platforms, fix bugs,    *

 * and add new features.  You are highly encouraged to send your changes   *

 * to the [email protected] mailing list for possible incorporation into the    *

 * main distribution.  By sending these changes to Fyodor or one of the    *

 * Insecure.Org development mailing lists, or checking them into the Nmap  *

 * source code repository, it is understood (unless you specify otherwise) *

 * that you are offering the Nmap Project (Insecure.Com LLC) the           *

 * unlimited, non-exclusive right to reuse, modify, and relicense the      *

 * code.  Nmap will always be available Open Source, but this is important *

 * because the inability to relicense code has caused devastating problems *

 * for other Free Software projects (such as KDE and NASM).  We also       *

 * occasionally relicense the code to third parties as discussed above.    *

 * If you wish to specify special license conditions of your               *

 * contributions, just say so when you send them.                          *

 *                                                                         *

 * This program is distributed in the hope that it will be useful, but     *

 * WITHOUT ANY WARRANTY; without even the implied warranty of              *

GNU GENERAL PUBLIC LICENSE

Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc.

59 Temple Place - Suite 330, Boston, MA  02111-1307, USA

Everyone is permitted to copy and distribute verbatim copies

of this license document, but changing it is not allowed.

Preamble

The licenses for most software are designed to take away your freedom to

share and change it. By contrast, the GNU General Public License is intended

to guarantee your freedom to share and change free software--to make sure

the software is free for all its users. This General Public License applies

to most of the Free Software Foundation's software and to any other program

whose authors commit to using it. (Some other Free Software Foundation

software is covered by the GNU Library General Public License instead.) You

can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our

General Public Licenses are designed to make sure that you have the freedom

to distribute copies of free software (and charge for this service if you

wish), that you receive source code or can get it if you want it, that you

can change the software or use pieces of it in new free programs; and that

you know you can do these things.

To protect your rights, we need to make restrictions that forbid anyone to

deny you these rights or to ask you to surrender the rights. These

restrictions translate to certain responsibilities for you if you distribute

copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether gratis or

for a fee, you must give the recipients all the rights that you have. You

must make sure that they, too, receive or can get the source code. And you

must show them these terms so they know their rights.

We protect your rights with two steps: (1) copyright the software, and (2)

offer you this license which gives you legal permission to copy, distribute

and/or modify the software.

Also, for each author's protection and ours, we want to make certain that

everyone understands that there is no warranty for this free software. If

the software is modified by someone else and passed on, we want its

recipients to know that what they have is not the original, so that any

problems introduced by others will not reflect on the original authors'

reputations.

Finally, any free program is threatened constantly by software patents. We

wish to avoid the danger that redistributors of a free program will

individually obtain patent licenses, in effect making the program

proprietary. To prevent this, we have made it clear that any patent must be

licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and modification

follow.

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0. This License applies to any program or other work which contains a notice

placed by the copyright holder saying it may be distributed under the terms

of this General Public License. The "Program", below, refers to any such

program or work, and a "work based on the Program" means either the Program

or any derivative work under copyright law: that is to say, a work

containing the Program or a portion of it, either verbatim or with

modifications and/or translated into another language. (Hereinafter,

translation is included without limitation in the term "modification".) Each

licensee is addressed as "you".

Activities other than copying, distribution and modification are not covered

by this License; they are outside its scope. The act of running the Program

is not restricted, and the output from the Program is covered only if its

contents constitute a work based on the Program (independent of having been

made by running the Program). Whether that is true depends on what the

Program does.

1. You may copy and distribute verbatim copies of the Program's source code

as you receive it, in any medium, provided that you conspicuously and

appropriately publish on each copy an appropriate copyright notice and

disclaimer of warranty; keep intact all the notices that refer to this

License and to the absence of any warranty; and give any other recipients of

the Program a copy of this License along with the Program.

You may charge a fee for the physical act of transferring a copy, and you

may at your option offer warranty protection in exchange for a fee.

2. You may modify your copy or copies of the Program or any portion of it,

thus forming a work based on the Program, and copy and distribute such

modifications or work under the terms of Section 1 above, provided that you

also meet all of these conditions:

   * a) You must cause the modified files to carry prominent notices stating

     that you changed the files and the date of any change.

   * b) You must cause any work that you distribute or publish, that in

     whole or in part contains or is derived from the Program or any part

     thereof, to be licensed as a whole at no charge to all third parties

     under the terms of this License.

   * c) If the modified program normally reads commands interactively when

     run, you must cause it, when started running for such interactive use

     in the most ordinary way, to print or display an announcement including

     an appropriate copyright notice and a notice that there is no warranty

     (or else, saying that you provide a warranty) and that users may

     redistribute the program under these conditions, and telling the user

     how to view a copy of this License. (Exception: if the Program itself

     is interactive but does not normally print such an announcement, your

     work based on the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole. If identifiable

sections of that work are not derived from the Program, and can be

reasonably considered independent and separate works in themselves, then

this License, and its terms, do not apply to those sections when you

distribute them as separate works. But when you distribute the same sections

as part of a whole which is a work based on the Program, the distribution of

the whole must be on the terms of this License, whose permissions for other

licensees extend to the entire whole, and thus to each and every part

regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest your

rights to work written entirely by you; rather, the intent is to exercise

the right to control the distribution of derivative or collective works

based on the Program.

In addition, mere aggregation of another work not based on the Program with

the Program (or with a work based on the Program) on a volume of a storage

or distribution medium does not bring the other work under the scope of this

License.

3. You may copy and distribute the Program (or a work based on it, under

Section 2) in object code or executable form under the terms of Sections 1

and 2 above provided that you also do one of the following:

   * a) Accompany it with the complete corresponding machine-readable source

     code, which must be distributed under the terms of Sections 1 and 2

     above on a medium customarily used for software interchange; or,

   * b) Accompany it with a written offer, valid for at least three years,

     to give any third party, for a charge no more than your cost of

     physically performing source distribution, a complete machine-readable

     copy of the corresponding source code, to be distributed under the

     terms of Sections 1 and 2 above on a medium customarily used for

     software interchange; or,

   * c) Accompany it with the information you received as to the offer to

     distribute corresponding source code. (This alternative is allowed only

     for noncommercial distribution and only if you received the program in

     object code or executable form with such an offer, in accord with

     Subsection b above.)

The source code for a work means the preferred form of the work for making

modifications to it. For an executable work, complete source code means all

the source code for all modules it contains, plus any associated interface

definition files, plus the scripts used to control compilation and

installation of the executable. However, as a special exception, the source

code distributed need not include anything that is normally distributed (in

either source or binary form) with the major components (compiler, kernel,

and so on) of the operating system on which the executable runs, unless that

component itself accompanies the executable.

If distribution of executable or object code is made by offering access to

copy from a designated place, then offering equivalent access to copy the

source code from the same place counts as distribution of the source code,

even though third parties are not compelled to copy the source along with

the object code.

4. You may not copy, modify, sublicense, or distribute the Program except as

expressly provided under this License. Any attempt otherwise to copy,

modify, sublicense or distribute the Program is void, and will automatically

terminate your rights under this License. However, parties who have received

copies, or rights, from you under this License will not have their licenses

terminated so long as such parties remain in full compliance.

5. You are not required to accept this License, since you have not signed

it. However, nothing else grants you permission to modify or distribute the

Program or its derivative works. These actions are prohibited by law if you

do not accept this License. Therefore, by modifying or distributing the

Program (or any work based on the Program), you indicate your acceptance of

this License to do so, and all its terms and conditions for copying,

distributing or modifying the Program or works based on it.

6. Each time you redistribute the Program (or any work based on the

Program), the recipient automatically receives a license from the original

licensor to copy, distribute or modify the Program subject to these terms

and conditions. You may not impose any further restrictions on the

recipients' exercise of the rights granted herein. You are not responsible

for enforcing compliance by third parties to this License.

7. If, as a consequence of a court judgment or allegation of patent

infringement or for any other reason (not limited to patent issues),

conditions are imposed on you (whether by court order, agreement or

otherwise) that contradict the conditions of this License, they do not

excuse you from the conditions of this License. If you cannot distribute so

as to satisfy simultaneously your obligations under this License and any

other pertinent obligations, then as a consequence you may not distribute

the Program at all. For example, if a patent license would not permit

royalty-free redistribution of the Program by all those who receive copies

directly or indirectly through you, then the only way you could satisfy both

it and this License would be to refrain entirely from distribution of the

Program.

If any portion of this section is held invalid or unenforceable under any

particular circumstance, the balance of the section is intended to apply and

the section as a whole is intended to apply in other circumstances.

It is not the purpose of this section to induce you to infringe any patents

or other property right claims or to contest validity of any such claims;

this section has the sole purpose of protecting the integrity of the free

software distribution system, which is implemented by public license

practices. Many people have made generous contributions to the wide range of

software distributed through that system in reliance on consistent

application of that system; it is up to the author/donor to decide if he or

she is willing to distribute software through any other system and a

licensee cannot impose that choice.

This section is intended to make thoroughly clear what is believed to be a

consequence of the rest of this License.

8. If the distribution and/or use of the Program is restricted in certain

countries either by patents or by copyrighted interfaces, the original

copyright holder who places the Program under this License may add an

explicit geographical distribution limitation excluding those countries, so

that distribution is permitted only in or among countries not thus excluded.

In such case, this License incorporates the limitation as if written in the

body of this License.

9. The Free Software Foundation may publish revised and/or new versions of

the General Public License from time to time. Such new versions will be

similar in spirit to the present version, but may differ in detail to

address new problems or concerns.

Each version is given a distinguishing version number. If the Program

specifies a version number of this License which applies to it and "any

later version", you have the option of following the terms and conditions

either of that version or of any later version published by the Free

Software Foundation. If the Program does not specify a version number of

this License, you may choose any version ever published by the Free Software

Foundation.

10. If you wish to incorporate parts of the Program into other free programs

whose distribution conditions are different, write to the author to ask for

permission. For software which is copyrighted by the Free Software

Foundation, write to the Free Software Foundation; we sometimes make

exceptions for this. Our decision will be guided by the two goals of

preserving the free status of all derivatives of our free software and of

promoting the sharing and reuse of software generally.

NO WARRANTY

11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR

THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN

OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES

PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED

OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF

MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO

THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM

PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR

CORRECTION.

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING

WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR

REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,

INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING

OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO

LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR

THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER

PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE

POSSIBILITY OF SUCH DAMAGES.

END OF TERMS AND CONDITIONS

How to Apply These Terms to Your New Programs

If you develop a new program, and you want it to be of the greatest possible

use to the public, the best way to achieve this is to make it free software

which everyone can redistribute and change under these terms.

To do so, attach the following notices to the program. It is safest to

attach them to the start of each source file to most effectively convey the

exclusion of warranty; and each file should have at least the "copyright"

line and a pointer to where the full notice is found.

one line to give the program's name and an idea of what it does.

Copyright (C) 19yy  name of author

This program is free software; you can redistribute it and/or

modify it under the terms of the GNU General Public License

as published by the Free Software Foundation; either version 2

of the License, or (at your option) any later version.

This program is distributed in the hope that it will be useful,

but WITHOUT ANY WARRANTY; without even the implied warranty of

MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the

GNU General Public License for more details.

You should have received a copy of the GNU General Public License

along with this program; if not, write to the Free Software

Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA  02111-1307, USA.

Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this when

it starts in an interactive mode:

Gnomovision version 69, Copyright (C) 19yy name of author

Gnomovision comes with ABSOLUTELY NO WARRANTY; for details

type `show w'.  This is free software, and you are welcome

to redistribute it under certain conditions; type `show c'

for details.

The hypothetical commands `show w' and `show c' should show the appropriate

parts of the General Public License. Of course, the commands you use may be

called something other than `show w' and `show c'; they could even be

mouse-clicks or menu items--whatever suits your program.

You should also get your employer (if you work as a programmer) or your

school, if any, to sign a "copyright disclaimer" for the program, if

necessary. Here is a sample; alter the names:

Yoyodyne, Inc., hereby disclaims all copyright

interest in the program `Gnomovision'

This General Public License does not permit incorporating your program into

proprietary programs. If your program is a subroutine library, you may

consider it more useful to permit linking proprietary applications with the

library. If this is what you want to do, use the GNU Library General Public

License instead of this License.
