By contrast, 15 | the GNU General Public License is intended to guarantee your freedom to 16 | share and change all versions of a program--to make sure it remains free 17 | software for all its users. We, the Free Software Foundation, use the 18 | GNU General Public License for most of our software; it applies also to 19 | any other work released this way by its authors. You can apply it to 20 | your programs, too. 21 | 22 | When we speak of free software, we are referring to freedom, not 23 | price. Our General Public Licenses are designed to make sure that you 24 | have the freedom to distribute copies of free software (and charge for 25 | them if you wish), that you receive source code or can get it if you 26 | want it, that you can change the software or use pieces of it in new 27 | free programs, and that you know you can do these things. 28 | 29 | To protect your rights, we need to prevent others from denying you 30 | these rights or asking you to surrender the rights. Therefore, you have 31 | certain responsibilities if you distribute copies of the software, or if 32 | you modify it: responsibilities to respect the freedom of others. 33 | 34 | For example, if you distribute copies of such a program, whether 35 | gratis or for a fee, you must pass on to the recipients the same 36 | freedoms that you received. You must make sure that they, too, receive 37 | or can get the source code. And you must show them these terms so they 38 | know their rights. 39 | 40 | Developers that use the GNU GPL protect your rights with two steps: 41 | (1) assert copyright on the software, and (2) offer you this License 42 | giving you legal permission to copy, distribute and/or modify it. 43 | 44 | For the developers' and authors' protection, the GPL clearly explains 45 | that there is no warranty for this free software. For both users' and 46 | authors' sake, the GPL requires that modified versions be marked as 47 | changed, so that their problems will not be attributed erroneously to 48 | authors of previous versions. 49 | 50 | Some devices are designed to deny users access to install or run 51 | modified versions of the software inside them, although the manufacturer 52 | can do so. This is fundamentally incompatible with the aim of 53 | protecting users' freedom to change the software. The systematic 54 | pattern of such abuse occurs in the area of products for individuals to 55 | use, which is precisely where it is most unacceptable. Therefore, we 56 | have designed this version of the GPL to prohibit the practice for those 57 | products. If such problems arise substantially in other domains, we 58 | stand ready to extend this provision to those domains in future versions 59 | of the GPL, as needed to protect the freedom of users. 60 | 61 | Finally, every program is threatened constantly by software patents. 62 | States should not allow patents to restrict development and use of 63 | software on general-purpose computers, but in those that do, we wish to 64 | avoid the special danger that patents applied to a free program could 65 | make it effectively proprietary. To prevent this, the GPL assures that 66 | patents cannot be used to render the program non-free. 67 | 68 | The precise terms and conditions for copying, distribution and 69 | modification follow. 70 | 71 | TERMS AND CONDITIONS 72 | 73 | 0. Definitions. 74 | 75 | "This License" refers to version 3 of the GNU General Public License. 76 | 77 | "Copyright" also means copyright-like laws that apply to other kinds of 78 | works, such as semiconductor masks. 79 | 80 | "The Program" refers to any copyrightable work licensed under this 81 | License. Each licensee is addressed as "you". "Licensees" and 82 | "recipients" may be individuals or organizations. 83 | 84 | To "modify" a work means to copy from or adapt all or part of the work 85 | in a fashion requiring copyright permission, other than the making of an 86 | exact copy. The resulting work is called a "modified version" of the 87 | earlier work or a work "based on" the earlier work. 88 | 89 | A "covered work" means either the unmodified Program or a work based 90 | on the Program. 91 | 92 | To "propagate" a work means to do anything with it that, without 93 | permission, would make you directly or secondarily liable for 94 | infringement under applicable copyright law, except executing it on a 95 | computer or modifying a private copy. Propagation includes copying, 96 | distribution (with or without modification), making available to the 97 | public, and in some countries other activities as well. 98 | 99 | To "convey" a work means any kind of propagation that enables other 100 | parties to make or receive copies. Mere interaction with a user through 101 | a computer network, with no transfer of a copy, is not conveying. 102 | 103 | An interactive user interface displays "Appropriate Legal Notices" 104 | to the extent that it includes a convenient and prominently visible 105 | feature that (1) displays an appropriate copyright notice, and (2) 106 | tells the user that there is no warranty for the work (except to the 107 | extent that warranties are provided), that licensees may convey the 108 | work under this License, and how to view a copy of this License. If 109 | the interface presents a list of user commands or options, such as a 110 | menu, a prominent item in the list meets this criterion. 111 | 112 | 1. Source Code. 113 | 114 | The "source code" for a work means the preferred form of the work 115 | for making modifications to it. "Object code" means any non-source 116 | form of a work. 117 | 118 | A "Standard Interface" means an interface that either is an official 119 | standard defined by a recognized standards body, or, in the case of 120 | interfaces specified for a particular programming language, one that 121 | is widely used among developers working in that language. 122 | 123 | The "System Libraries" of an executable work include anything, other 124 | than the work as a whole, that (a) is included in the normal form of 125 | packaging a Major Component, but which is not part of that Major 126 | Component, and (b) serves only to enable use of the work with that 127 | Major Component, or to implement a Standard Interface for which an 128 | implementation is available to the public in source code form. A 129 | "Major Component", in this context, means a major essential component 130 | (kernel, window system, and so on) of the specific operating system 131 | (if any) on which the executable work runs, or a compiler used to 132 | produce the work, or an object code interpreter used to run it. 133 | 134 | The "Corresponding Source" for a work in object code form means all 135 | the source code needed to generate, install, and (for an executable 136 | work) run the object code and to modify the work, including scripts to 137 | control those activities. However, it does not include the work's 138 | System Libraries, or general-purpose tools or generally available free 139 | programs which are used unmodified in performing those activities but 140 | which are not part of the work. For example, Corresponding Source 141 | includes interface definition files associated with source files for 142 | the work, and the source code for shared libraries and dynamically 143 | linked subprograms that the work is specifically designed to require, 144 | such as by intimate data communication or control flow between those 145 | subprograms and other parts of the work. 146 | 147 | The Corresponding Source need not include anything that users 148 | can regenerate automatically from other parts of the Corresponding 149 | Source. 150 | 151 | The Corresponding Source for a work in source code form is that 152 | same work. 153 | 154 | 2. Basic Permissions. 155 | 156 | All rights granted under this License are granted for the term of 157 | copyright on the Program, and are irrevocable provided the stated 158 | conditions are met. This License explicitly affirms your unlimited 159 | permission to run the unmodified Program. The output from running a 160 | covered work is covered by this License only if the output, given its 161 | content, constitutes a covered work. This License acknowledges your 162 | rights of fair use or other equivalent, as provided by copyright law. 163 | 164 | You may make, run and propagate covered works that you do not 165 | convey, without conditions so long as your license otherwise remains 166 | in force. You may convey covered works to others for the sole purpose 167 | of having them make modifications exclusively for you, or provide you 168 | with facilities for running those works, provided that you comply with 169 | the terms of this License in conveying all material for which you do 170 | not control copyright. Those thus making or running the covered works 171 | for you must do so exclusively on your behalf, under your direction 172 | and control, on terms that prohibit them from making any copies of 173 | your copyrighted material outside their relationship with you. 174 | 175 | Conveying under any other circumstances is permitted solely under 176 | the conditions stated below. Sublicensing is not allowed; section 10 177 | makes it unnecessary. 178 | 179 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 180 | 181 | No covered work shall be deemed part of an effective technological 182 | measure under any applicable law fulfilling obligations under article 183 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or 184 | similar laws prohibiting or restricting circumvention of such 185 | measures. 186 | 187 | When you convey a covered work, you waive any legal power to forbid 188 | circumvention of technological measures to the extent such circumvention 189 | is effected by exercising rights under this License with respect to 190 | the covered work, and you disclaim any intention to limit operation or 191 | modification of the work as a means of enforcing, against the work's 192 | users, your or third parties' legal rights to forbid circumvention of 193 | technological measures. 194 | 195 | 4. Conveying Verbatim Copies. 196 | 197 | You may convey verbatim copies of the Program's source code as you 198 | receive it, in any medium, provided that you conspicuously and 199 | appropriately publish on each copy an appropriate copyright notice; 200 | keep intact all notices stating that this License and any 201 | non-permissive terms added in accord with section 7 apply to the code; 202 | keep intact all notices of the absence of any warranty; and give all 203 | recipients a copy of this License along with the Program. 204 | 205 | You may charge any price or no price for each copy that you convey, 206 | and you may offer support or warranty protection for a fee. 207 | 208 | 5. Conveying Modified Source Versions. 209 | 210 | You may convey a work based on the Program, or the modifications to 211 | produce it from the Program, in the form of source code under the 212 | terms of section 4, provided that you also meet all of these conditions: 213 | 214 | a) The work must carry prominent notices stating that you modified 215 | it, and giving a relevant date. 216 | 217 | b) The work must carry prominent notices stating that it is 218 | released under this License and any conditions added under section 219 | 7. This requirement modifies the requirement in section 4 to 220 | "keep intact all notices". 221 | 222 | c) You must license the entire work, as a whole, under this 223 | License to anyone who comes into possession of a copy. This 224 | License will therefore apply, along with any applicable section 7 225 | additional terms, to the whole of the work, and all its parts, 226 | regardless of how they are packaged. This License gives no 227 | permission to license the work in any other way, but it does not 228 | invalidate such permission if you have separately received it. 229 | 230 | d) If the work has interactive user interfaces, each must display 231 | Appropriate Legal Notices; however, if the Program has interactive 232 | interfaces that do not display Appropriate Legal Notices, your 233 | work need not make them do so. 234 | 235 | A compilation of a covered work with other separate and independent 236 | works, which are not by their nature extensions of the covered work, 237 | and which are not combined with it such as to form a larger program, 238 | in or on a volume of a storage or distribution medium, is called an 239 | "aggregate" if the compilation and its resulting copyright are not 240 | used to limit the access or legal rights of the compilation's users 241 | beyond what the individual works permit. Inclusion of a covered work 242 | in an aggregate does not cause this License to apply to the other 243 | parts of the aggregate. 244 | 245 | 6. Conveying Non-Source Forms. 246 | 247 | You may convey a covered work in object code form under the terms 248 | of sections 4 and 5, provided that you also convey the 249 | machine-readable Corresponding Source under the terms of this License, 250 | in one of these ways: 251 | 252 | a) Convey the object code in, or embodied in, a physical product 253 | (including a physical distribution medium), accompanied by the 254 | Corresponding Source fixed on a durable physical medium 255 | customarily used for software interchange. 256 | 257 | b) Convey the object code in, or embodied in, a physical product 258 | (including a physical distribution medium), accompanied by a 259 | written offer, valid for at least three years and valid for as 260 | long as you offer spare parts or customer support for that product 261 | model, to give anyone who possesses the object code either (1) a 262 | copy of the Corresponding Source for all the software in the 263 | product that is covered by this License, on a durable physical 264 | medium customarily used for software interchange, for a price no 265 | more than your reasonable cost of physically performing this 266 | conveying of source, or (2) access to copy the 267 | Corresponding Source from a network server at no charge. 268 | 269 | c) Convey individual copies of the object code with a copy of the 270 | written offer to provide the Corresponding Source. This 271 | alternative is allowed only occasionally and noncommercially, and 272 | only if you received the object code with such an offer, in accord 273 | with subsection 6b. 274 | 275 | d) Convey the object code by offering access from a designated 276 | place (gratis or for a charge), and offer equivalent access to the 277 | Corresponding Source in the same way through the same place at no 278 | further charge. You need not require recipients to copy the 279 | Corresponding Source along with the object code. If the place to 280 | copy the object code is a network server, the Corresponding Source 281 | may be on a different server (operated by you or a third party) 282 | that supports equivalent copying facilities, provided you maintain 283 | clear directions next to the object code saying where to find the 284 | Corresponding Source. Regardless of what server hosts the 285 | Corresponding Source, you remain obligated to ensure that it is 286 | available for as long as needed to satisfy these requirements. 287 | 288 | e) Convey the object code using peer-to-peer transmission, provided 289 | you inform other peers where the object code and Corresponding 290 | Source of the work are being offered to the general public at no 291 | charge under subsection 6d. 292 | 293 | A separable portion of the object code, whose source code is excluded 294 | from the Corresponding Source as a System Library, need not be 295 | included in conveying the object code work. 296 | 297 | A "User Product" is either (1) a "consumer product", which means any 298 | tangible personal property which is normally used for personal, family, 299 | or household purposes, or (2) anything designed or sold for incorporation 300 | into a dwelling. In determining whether a product is a consumer product, 301 | doubtful cases shall be resolved in favor of coverage. For a particular 302 | product received by a particular user, "normally used" refers to a 303 | typical or common use of that class of product, regardless of the status 304 | of the particular user or of the way in which the particular user 305 | actually uses, or expects or is expected to use, the product. A product 306 | is a consumer product regardless of whether the product has substantial 307 | commercial, industrial or non-consumer uses, unless such uses represent 308 | the only significant mode of use of the product. 309 | 310 | "Installation Information" for a User Product means any methods, 311 | procedures, authorization keys, or other information required to install 312 | and execute modified versions of a covered work in that User Product from 313 | a modified version of its Corresponding Source. The information must 314 | suffice to ensure that the continued functioning of the modified object 315 | code is in no case prevented or interfered with solely because 316 | modification has been made. 317 | 318 | If you convey an object code work under this section in, or with, or 319 | specifically for use in, a User Product, and the conveying occurs as 320 | part of a transaction in which the right of possession and use of the 321 | User Product is transferred to the recipient in perpetuity or for a 322 | fixed term (regardless of how the transaction is characterized), the 323 | Corresponding Source conveyed under this section must be accompanied 324 | by the Installation Information. But this requirement does not apply 325 | if neither you nor any third party retains the ability to install 326 | modified object code on the User Product (for example, the work has 327 | been installed in ROM). 328 | 329 | The requirement to provide Installation Information does not include a 330 | requirement to continue to provide support service, warranty, or updates 331 | for a work that has been modified or installed by the recipient, or for 332 | the User Product in which it has been modified or installed. Access to a 333 | network may be denied when the modification itself materially and 334 | adversely affects the operation of the network or violates the rules and 335 | protocols for communication across the network. 336 | 337 | Corresponding Source conveyed, and Installation Information provided, 338 | in accord with this section must be in a format that is publicly 339 | documented (and with an implementation available to the public in 340 | source code form), and must require no special password or key for 341 | unpacking, reading or copying. 342 | 343 | 7. Additional Terms. 344 | 345 | "Additional permissions" are terms that supplement the terms of this 346 | License by making exceptions from one or more of its conditions. 347 | Additional permissions that are applicable to the entire Program shall 348 | be treated as though they were included in this License, to the extent 349 | that they are valid under applicable law. If additional permissions 350 | apply only to part of the Program, that part may be used separately 351 | under those permissions, but the entire Program remains governed by 352 | this License without regard to the additional permissions. 353 | 354 | When you convey a copy of a covered work, you may at your option 355 | remove any additional permissions from that copy, or from any part of 356 | it. (Additional permissions may be written to require their own 357 | removal in certain cases when you modify the work.) You may place 358 | additional permissions on material, added by you to a covered work, 359 | for which you have or can give appropriate copyright permission. 360 | 361 | Notwithstanding any other provision of this License, for material you 362 | add to a covered work, you may (if authorized by the copyright holders of 363 | that material) supplement the terms of this License with terms: 364 | 365 | a) Disclaiming warranty or limiting liability differently from the 366 | terms of sections 15 and 16 of this License; or 367 | 368 | b) Requiring preservation of specified reasonable legal notices or 369 | author attributions in that material or in the Appropriate Legal 370 | Notices displayed by works containing it; or 371 | 372 | c) Prohibiting misrepresentation of the origin of that material, or 373 | requiring that modified versions of such material be marked in 374 | reasonable ways as different from the original version; or 375 | 376 | d) Limiting the use for publicity purposes of names of licensors or 377 | authors of the material; or 378 | 379 | e) Declining to grant rights under trademark law for use of some 380 | trade names, trademarks, or service marks; or 381 | 382 | f) Requiring indemnification of licensors and authors of that 383 | material by anyone who conveys the material (or modified versions of 384 | it) with contractual assumptions of liability to the recipient, for 385 | any liability that these contractual assumptions directly impose on 386 | those licensors and authors. 387 | 388 | All other non-permissive additional terms are considered "further 389 | restrictions" within the meaning of section 10. If the Program as you 390 | received it, or any part of it, contains a notice stating that it is 391 | governed by this License along with a term that is a further 392 | restriction, you may remove that term. If a license document contains 393 | a further restriction but permits relicensing or conveying under this 394 | License, you may add to a covered work material governed by the terms 395 | of that license document, provided that the further restriction does 396 | not survive such relicensing or conveying. 397 | 398 | If you add terms to a covered work in accord with this section, you 399 | must place, in the relevant source files, a statement of the 400 | additional terms that apply to those files, or a notice indicating 401 | where to find the applicable terms. 402 | 403 | Additional terms, permissive or non-permissive, may be stated in the 404 | form of a separately written license, or stated as exceptions; 405 | the above requirements apply either way. 406 | 407 | 8. Termination. 408 | 409 | You may not propagate or modify a covered work except as expressly 410 | provided under this License. Any attempt otherwise to propagate or 411 | modify it is void, and will automatically terminate your rights under 412 | this License (including any patent licenses granted under the third 413 | paragraph of section 11). 414 | 415 | However, if you cease all violation of this License, then your 416 | license from a particular copyright holder is reinstated (a) 417 | provisionally, unless and until the copyright holder explicitly and 418 | finally terminates your license, and (b) permanently, if the copyright 419 | holder fails to notify you of the violation by some reasonable means 420 | prior to 60 days after the cessation. 421 | 422 | Moreover, your license from a particular copyright holder is 423 | reinstated permanently if the copyright holder notifies you of the 424 | violation by some reasonable means, this is the first time you have 425 | received notice of violation of this License (for any work) from that 426 | copyright holder, and you cure the violation prior to 30 days after 427 | your receipt of the notice. 428 | 429 | Termination of your rights under this section does not terminate the 430 | licenses of parties who have received copies or rights from you under 431 | this License. If your rights have been terminated and not permanently 432 | reinstated, you do not qualify to receive new licenses for the same 433 | material under section 10. 434 | 435 | 9. Acceptance Not Required for Having Copies. 436 | 437 | You are not required to accept this License in order to receive or 438 | run a copy of the Program. Ancillary propagation of a covered work 439 | occurring solely as a consequence of using peer-to-peer transmission 440 | to receive a copy likewise does not require acceptance. However, 441 | nothing other than this License grants you permission to propagate or 442 | modify any covered work. These actions infringe copyright if you do 443 | not accept this License. Therefore, by modifying or propagating a 444 | covered work, you indicate your acceptance of this License to do so. 445 | 446 | 10. Automatic Licensing of Downstream Recipients. 447 | 448 | Each time you convey a covered work, the recipient automatically 449 | receives a license from the original licensors, to run, modify and 450 | propagate that work, subject to this License. You are not responsible 451 | for enforcing compliance by third parties with this License. 452 | 453 | An "entity transaction" is a transaction transferring control of an 454 | organization, or substantially all assets of one, or subdividing an 455 | organization, or merging organizations. If propagation of a covered 456 | work results from an entity transaction, each party to that 457 | transaction who receives a copy of the work also receives whatever 458 | licenses to the work the party's predecessor in interest had or could 459 | give under the previous paragraph, plus a right to possession of the 460 | Corresponding Source of the work from the predecessor in interest, if 461 | the predecessor has it or can get it with reasonable efforts. 462 | 463 | You may not impose any further restrictions on the exercise of the 464 | rights granted or affirmed under this License. For example, you may 465 | not impose a license fee, royalty, or other charge for exercise of 466 | rights granted under this License, and you may not initiate litigation 467 | (including a cross-claim or counterclaim in a lawsuit) alleging that 468 | any patent claim is infringed by making, using, selling, offering for 469 | sale, or importing the Program or any portion of it. 470 | 471 | 11. Patents. 472 | 473 | A "contributor" is a copyright holder who authorizes use under this 474 | License of the Program or a work on which the Program is based. The 475 | work thus licensed is called the contributor's "contributor version". 476 | 477 | A contributor's "essential patent claims" are all patent claims 478 | owned or controlled by the contributor, whether already acquired or 479 | hereafter acquired, that would be infringed by some manner, permitted 480 | by this License, of making, using, or selling its contributor version, 481 | but do not include claims that would be infringed only as a 482 | consequence of further modification of the contributor version. For 483 | purposes of this definition, "control" includes the right to grant 484 | patent sublicenses in a manner consistent with the requirements of 485 | this License. 486 | 487 | Each contributor grants you a non-exclusive, worldwide, royalty-free 488 | patent license under the contributor's essential patent claims, to 489 | make, use, sell, offer for sale, import and otherwise run, modify and 490 | propagate the contents of its contributor version. 491 | 492 | In the following three paragraphs, a "patent license" is any express 493 | agreement or commitment, however denominated, not to enforce a patent 494 | (such as an express permission to practice a patent or covenant not to 495 | sue for patent infringement). To "grant" such a patent license to a 496 | party means to make such an agreement or commitment not to enforce a 497 | patent against the party. 498 | 499 | If you convey a covered work, knowingly relying on a patent license, 500 | and the Corresponding Source of the work is not available for anyone 501 | to copy, free of charge and under the terms of this License, through a 502 | publicly available network server or other readily accessible means, 503 | then you must either (1) cause the Corresponding Source to be so 504 | available, or (2) arrange to deprive yourself of the benefit of the 505 | patent license for this particular work, or (3) arrange, in a manner 506 | consistent with the requirements of this License, to extend the patent 507 | license to downstream recipients. "Knowingly relying" means you have 508 | actual knowledge that, but for the patent license, your conveying the 509 | covered work in a country, or your recipient's use of the covered work 510 | in a country, would infringe one or more identifiable patents in that 511 | country that you have reason to believe are valid. 512 | 513 | If, pursuant to or in connection with a single transaction or 514 | arrangement, you convey, or propagate by procuring conveyance of, a 515 | covered work, and grant a patent license to some of the parties 516 | receiving the covered work authorizing them to use, propagate, modify 517 | or convey a specific copy of the covered work, then the patent license 518 | you grant is automatically extended to all recipients of the covered 519 | work and works based on it. 520 | 521 | A patent license is "discriminatory" if it does not include within 522 | the scope of its coverage, prohibits the exercise of, or is 523 | conditioned on the non-exercise of one or more of the rights that are 524 | specifically granted under this License. You may not convey a covered 525 | work if you are a party to an arrangement with a third party that is 526 | in the business of distributing software, under which you make payment 527 | to the third party based on the extent of your activity of conveying 528 | the work, and under which the third party grants, to any of the 529 | parties who would receive the covered work from you, a discriminatory 530 | patent license (a) in connection with copies of the covered work 531 | conveyed by you (or copies made from those copies), or (b) primarily 532 | for and in connection with specific products or compilations that 533 | contain the covered work, unless you entered into that arrangement, 534 | or that patent license was granted, prior to 28 March 2007. 535 | 536 | Nothing in this License shall be construed as excluding or limiting 537 | any implied license or other defenses to infringement that may 538 | otherwise be available to you under applicable patent law. 539 | 540 | 12. No Surrender of Others' Freedom. 541 | 542 | If conditions are imposed on you (whether by court order, agreement or 543 | otherwise) that contradict the conditions of this License, they do not 544 | excuse you from the conditions of this License. If you cannot convey a 545 | covered work so as to satisfy simultaneously your obligations under this 546 | License and any other pertinent obligations, then as a consequence you may 547 | not convey it at all. For example, if you agree to terms that obligate you 548 | to collect a royalty for further conveying from those to whom you convey 549 | the Program, the only way you could satisfy both those terms and this 550 | License would be to refrain entirely from conveying the Program. 551 | 552 | 13. Use with the GNU Affero General Public License. 553 | 554 | Notwithstanding any other provision of this License, you have 555 | permission to link or combine any covered work with a work licensed 556 | under version 3 of the GNU Affero General Public License into a single 557 | combined work, and to convey the resulting work. The terms of this 558 | License will continue to apply to the part which is the covered work, 559 | but the special requirements of the GNU Affero General Public License, 560 | section 13, concerning interaction through a network will apply to the 561 | combination as such. 562 | 563 | 14. Revised Versions of this License. 564 | 565 | The Free Software Foundation may publish revised and/or new versions of 566 | the GNU General Public License from time to time. Such new versions will 567 | be similar in spirit to the present version, but may differ in detail to 568 | address new problems or concerns. 569 | 570 | Each version is given a distinguishing version number. If the 571 | Program specifies that a certain numbered version of the GNU General 572 | Public License "or any later version" applies to it, you have the 573 | option of following the terms and conditions either of that numbered 574 | version or of any later version published by the Free Software 575 | Foundation. If the Program does not specify a version number of the 576 | GNU General Public License, you may choose any version ever published 577 | by the Free Software Foundation. 578 | 579 | If the Program specifies that a proxy can decide which future 580 | versions of the GNU General Public License can be used, that proxy's 581 | public statement of acceptance of a version permanently authorizes you 582 | to choose that version for the Program. 583 | 584 | Later license versions may give you additional or different 585 | permissions. However, no additional obligations are imposed on any 586 | author or copyright holder as a result of your choosing to follow a 587 | later version. 588 | 589 | 15. Disclaimer of Warranty. 590 | 591 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 592 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 593 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 594 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 595 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 596 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 597 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 598 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 599 | 600 | 16. Limitation of Liability. 601 | 602 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 603 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 604 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 605 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 606 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 607 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 608 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 609 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 610 | SUCH DAMAGES. 611 | 612 | 17. Interpretation of Sections 15 and 16. 613 | 614 | If the disclaimer of warranty and limitation of liability provided 615 | above cannot be given local legal effect according to their terms, 616 | reviewing courts shall apply local law that most closely approximates 617 | an absolute waiver of all civil liability in connection with the 618 | Program, unless a warranty or assumption of liability accompanies a 619 | copy of the Program in return for a fee. 620 | 621 | END OF TERMS AND CONDITIONS 622 | 623 | How to Apply These Terms to Your New Programs 624 | 625 | If you develop a new program, and you want it to be of the greatest 626 | possible use to the public, the best way to achieve this is to make it 627 | free software which everyone can redistribute and change under these terms. 628 | 629 | To do so, attach the following notices to the program. It is safest 630 | to attach them to the start of each source file to most effectively 631 | state the exclusion of warranty; and each file should have at least 632 | the "copyright" line and a pointer to where the full notice is found. 633 | 634 | 635 | Copyright (C) 636 | 637 | This program is free software: you can redistribute it and/or modify 638 | it under the terms of the GNU General Public License as published by 639 | the Free Software Foundation, either version 3 of the License, or 640 | (at your option) any later version. 641 | 642 | This program is distributed in the hope that it will be useful, 643 | but WITHOUT ANY WARRANTY; without even the implied warranty of 644 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 645 | GNU General Public License for more details. 646 | 647 | You should have received a copy of the GNU General Public License 648 | along with this program. If not, see . 649 | 650 | Also add information on how to contact you by electronic and paper mail. 651 | 652 | If the program does terminal interaction, make it output a short 653 | notice like this when it starts in an interactive mode: 654 | 655 | Copyright (C) 656 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 657 | This is free software, and you are welcome to redistribute it 658 | under certain conditions; type `show c' for details. 659 | 660 | The hypothetical commands `show w' and `show c' should show the appropriate 661 | parts of the General Public License. Of course, your program's commands 662 | might be different; for a GUI interface, you would use an "about box". 663 | 664 | You should also get your employer (if you work as a programmer) or school, 665 | if any, to sign a "copyright disclaimer" for the program, if necessary. 666 | For more information on this, and how to apply and follow the GNU GPL, see 667 | . 668 | 669 | The GNU General Public License does not permit incorporating your program 670 | into proprietary programs. If your program is a subroutine library, you 671 | may consider it more useful to permit linking proprietary applications with 672 | the library. If this is what you want to do, use the GNU Lesser General 673 | Public License instead of this License. But first, please read 674 | . 675 | 676 | -------------------------------------------------------------------------------- /MANIFEST.in: -------------------------------------------------------------------------------- 1 | include requirements.txt 2 | include README.md 3 | include LICENSE.md 4 | include osfooler_ng/dep/* 5 | include osfooler_ng/* 6 | recursive-exclude osfooler_ng *.pyc 7 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | 2 |

If you know how to properly move NetfilterQueue to Python 3.6+ and can test the project nicely and in short time - [your help is welcome](https://github.com/moonbaseDelta/OSfooler-ng/issues/1). 22 | 23 | Original author's project presentation can be found on Youtube [https://www.youtube.com/watch?v=psxxT00KavM](https://www.youtube.com/watch?v=psxxT00KavM). You may also find a few articles about OSfooler-NG. This version is a remake of 2014' OSfooler made by the same person, but the old one is archived and should be concidered lost. 24 | The whole topic of OS-fingerprinting and it's defeating is rather obscure. 25 | OSfooler-NG is working, but not yet perfect even against nmap and p0f. Any futher help, even testcases, and so is highly needed. 26 | 27 | By now it's been tested fine on Arch and CentOS7, CentOS8, Ubuntu 18.04. 28 | 29 | 30 | 31 | **You may help hugely by trying this on different distros and submit issues.** 32 | By now it's been tested fine on Arch and CentOS7. 33 | 34 | 35 | 36 | # Installation 37 | 38 | 39 | To get this version, just use git: 40 | ``` 41 | $ git clone https://github.com/moonbaseDelta/OSfooler-ng.git 42 | ``` 43 | You need to install python NetfilterQueue (v0.8.1 or more) linux package.

The file also contains a detailed discussion | 10 | # | of all metrics examined by p0f, and some practical notes on how to | 11 | # | add new signatures. | 12 | # `-------------------------------------------------------------------------' 13 | # 14 | # (C) Copyright 2000-2006 by Michal Zalewski 15 | # 16 | # Each line in this file specifies a single fingerprint. Please read the 17 | # information below carefully before attempting to append any signatures 18 | # reported by p0f as UNKNOWN to this file to avoid mistakes. Note that 19 | # this file is compatible only with the default operation mode, and not 20 | # with -R or -A options (SYN+ACK and RST+ modes). 21 | # 22 | # We use the following set metrics for fingerprinting: 23 | # 24 | # - Window size (WSS) - a highly OS dependent setting used for TCP/IP 25 | # performance control (max. amount of data to be sent without ACK). 26 | # Some systems use a fixed value for initial packets. On other 27 | # systems, it is a multiple of MSS or MTU (MSS+40). In some rare 28 | # cases, the value is just arbitrary. 29 | # 30 | # NEW SIGNATURE: if p0f reported a special value of 'Snn', the number 31 | # appears to be a multiple of MSS (MSS*nn); a special value of 'Tnn' 32 | # means it is a multiple of MTU ((MSS+40)*nn). Unless you notice the 33 | # value of nn is not fixed (unlikely), just copy the Snn or Tnn token 34 | # literally. If you know this device has a simple stack and a fixed 35 | # MTU, you can however multiply S value by MSS, or T value by MSS+40, 36 | # and put it instead of Snn or Tnn. One system may exhibit several T 37 | # or S values. In some situations, this might be a source of some 38 | # additional information about the setup if you have some time to dig 39 | # thru the kernel sources; in some other cases, like Windows, there seem 40 | # to be a multitude of variants and WSS selection algorithms, but it's 41 | # rather difficult to find a pattern without having the source. 42 | # 43 | # If WSS looks like a regular fixed value (for example is a power of two), 44 | # or if you can confirm the value is fixed by looking at several 45 | # fingerprints, please quote it literaly. If there's no apparent pattern 46 | # in WSS chosen, you should consider wildcarding this value - but this 47 | # should be the last option. 48 | # 49 | # NOTE: Some NAT devices, such as Linux iptables with --set-mss, will 50 | # modify MSS, but not WSS. As a result, MSS is changed to reflect 51 | # the MTU of the NAT device, but WSS remains a multiple of the original 52 | # MSS. Fortunately for us, the source device would almost always be 53 | # hooked up to Ethernet. P0f handles it automatically for the original 54 | # MSS of 1460, by adding "NAT!" tag to the result. 55 | # 56 | # In certain configurations, Linux erratically (?) uses MTU from another 57 | # interface on the default gw interface. This only happens on systems with 58 | # two network interfaces. Thus, some Linux systems that do not go thru NAT, 59 | # but have multiple interfaces instead, will be also tagged this way. 60 | # 61 | # P0f recognizes and automatically wildcards WSS of 12345, as generated 62 | # by sendack and sendsyn utilities shipped with the program, when 63 | # reporting a new signature. See test/sendack.c and test/sendsyn.c for more 64 | # information about this. 65 | # 66 | # - Overall packet size - a function of all IP and TCP options and bugs. 67 | # While this is partly redundant in the real world, we record this value 68 | # to capture rare cases when there are IP options (which we do not currently 69 | # examine) or packet data past the headers. Both situations are rare. 70 | # 71 | # Packet size MAY be wildcarded, but the meaning of the wildcard is 72 | # very special, and means the packet must be larger than PACKET_BIG 73 | # (defined in config.h as 100). This is usually not necessary, except 74 | # for some really broken implementations in RST+ mode. For more information, 75 | # see p0fr.fp. P0f automatically wildcards big packets when reporting 76 | # new signatures. 77 | # 78 | # NEW SIGNATURE: Copy this value literally. 79 | # 80 | # - Initial TTL - We check the actual TTL of a received packet. It can't 81 | # be higher than the initial TTL, and also shouldn't be dramatically 82 | # lower (maximum distance is defined in config.h as 40 hops). 83 | # 84 | # NEW SIGNATURE: *Never* copy TTL from a p0f-reported signature literally. 85 | # You need to determine the initial TTL. The best way to do it is to 86 | # check the documentation for a remote system, or check its settings. 87 | # A fairly good method is to simply round the observed TTL up to 88 | # 32, 64, 128, or 255, but it should be noted that some obscure devices 89 | # might not use round TTLs (in particular, some shoddy appliances and 90 | # IRIX and Tru64 are known to use "original" initial TTL settings). If not 91 | # sure, use traceroute or mtr to see how far you are from the host. 92 | # 93 | # Note that -F option overrides this check if no signature can be found. 94 | # 95 | # - Don't fragment flag (DF) - some modern OSes set this to implement PMTU 96 | # discovery. Others do not bother. 97 | # 98 | # NEW SIGNATURE: Copy this value literally. Note: this setting is 99 | # sometimes cleared by firewalls and/or certain connectivity clients. 100 | # Try to find out what's the actual state for a given OS if you see both, 101 | # and add the right one. P0f will automatically detect a case when a 102 | # firewall removed the DF flag and will append "(firewall!)" suffix to 103 | # the signature, so if the DF version is the right one, don't add no-DF 104 | # variant, unless it has a different meaning. 105 | # 106 | # - Maximum segment size (MSS) - this setting is usually link-dependent. P0f 107 | # uses it to determine link type of the remote host. 108 | # 109 | # NEW SIGNATURE: Always wildcard this value, except for rare cases when 110 | # you have an appliance with a fixed value, know the system supports only 111 | # a very limited number of network interface types, or know the system 112 | # is using a value it pulled out of nowhere. I use specific unique MSS 113 | # to tell Google crawlbots from the rest of Linux population, for example. 114 | # 115 | # If a specific MSS/MTU is unique to a certain link type, be sure to 116 | # add it to mtu.h instead of creating several variants of each signature. 117 | # 118 | # - Window scaling (WSCALE) - this feature is used to scale WSS. 119 | # It extends the size of a TCP/IP window to 32 bits, of sorts. Some modern 120 | # systems implement this feature. 121 | # 122 | # NEW SIGNATURE: Observe several signatures. Initial WSCALE is often set 123 | # to zero or other low value. There's usually no need to wildcard this 124 | # parameter. 125 | # 126 | # - Timestamp - some systems that implement timestamps set them to 127 | # zero in the initial SYN. This case is detected and handled appropriately. 128 | # 129 | # NEW SIGNATURE: Copy T or T0 option literally. 130 | # 131 | # - Selective ACK permitted - a flag set by systems that implement 132 | # selective ACK functionality, 133 | # 134 | # NEW SIGNATURE: copy S option literally. 135 | # 136 | # - NOP option - its presence, count and sequence is a useful OS-dependent 137 | # characteristic, 138 | # 139 | # NEW SIGNATURE: copy N options literally. 140 | # 141 | # - Other and unrecognized options (TTCP-related and such) - implemented by 142 | # some eccentric or very buggy TCP/IP stacks ;-), 143 | # 144 | # NEW SIGNATURE: copy ? options literally. 145 | # 146 | # - EOL option. Contrary to the popular belief, the presence of EOL 147 | # option is actually quite rare, most systems just NOP-pad to the 148 | # packet boundary. 149 | # 150 | # NEW SIGNATURE: copy E option literally. 151 | # 152 | # - The sequence of TCP all options mentioned above - this is very 153 | # specific to the implementation, 154 | # 155 | # NEW SIGNATURE: Copy the sequence literally. 156 | # 157 | # - Quirks. Some buggy stacks set certain values that should be zeroed in a 158 | # TCP packet to non-zero values. This has no effect as of today, but is 159 | # a valuable source of information. Some systems actually seem to leak 160 | # memory there. Other systems just exhibit harmful but very specific 161 | # behavior. This section captures all unusual yes-no properties not 162 | # related to the main and expected header layout. We detect the following: 163 | # 164 | # - Data past the headers. Neither SYN nor SYN+ACK packets are supposed 165 | # to carry any payload. If they do, we should take notice. The actual 166 | # payload is not examined, but will be displayed if use the -X option. 167 | # Note that payload is not unusual in RST+ mode (see p0fr.fp), very 168 | # rare otherwise. 169 | # 170 | # - Options past EOL. Some systems have some trailing data past EOL 171 | # in the options section of TCP/IP headers. P0f does not examine this 172 | # data as of today, simply detects its presence. If there is a 173 | # confirmed sizable population of systems that have data past EOL, it 174 | # might be a good idea to look at it. Until then, you have to recompile 175 | # p0f with DEBUG_EXTRAS set or use -x to display this data, 176 | # 177 | # - Zero IP ID. This again is a (mostly) harmless setting to use a fixed 178 | # IP ID for packets with DF set. Some systems reportedly use zero ID, 179 | # most OSes do not. There is a very slight probability of a false 180 | # positive when IP ID is "naturally" chosen to be zero on a system 181 | # that otherwise does set proper values, but the probability is 182 | # neglible (if it becomes a problem, recompile p0f with IGNORE_ZEROID 183 | # set in the sources). 184 | # 185 | # - IP options specified. Usually, packets do not have any IP options 186 | # set, but there can be some. Until there is a confirmed sizable 187 | # population of systems that do have IP options in a packet, p0f 188 | # does not examine those in detail, but it might change (use 189 | # DEBUG_EXTRAS or -x to display IP options if any found), 190 | # 191 | # - URG pointer value. SYN packets do not have URG flag set, so the 192 | # value in URG pointer in TCP header is ignored. Most systems set it 193 | # to zero, but some OSes (some versions of Windows, for example) do 194 | # not zero this field or even simply leak memory; the actual value is 195 | # not examined, because most cases seem to be just random garbage 196 | # (you can use DEBUG_EXTRAS or -x to report this information though); 197 | # see doc/win-memleak.txt for more information, 198 | # 199 | # - "Unused" field value. This should be always zero, but some systems 200 | # forget to clear it. This might result in some funny issues in the 201 | # future. P0f checks for non-zero value (and will display it if 202 | # DEBUG_EXTRAS is set, or you can use -x), 203 | # 204 | # - ACK number non-zero. ACK value in SYN packets with no ACK flag 205 | # is disregarded and is usually set to zero (just like with URG 206 | # pointer), but some systems forget to do it. The exact value is 207 | # not examined (but will be displayed with DEBUG_EXTRAS, or you can 208 | # use -x). Note that this is not an anomaly in SYN+ACK and RST+ modes, 209 | # 210 | # - Non-zero second timestamp. The initial SYN packet should have the 211 | # second timestamp always zeroed. SYN+ACK and RST+ may "legally" have 212 | # this quirk though, 213 | # 214 | # - Unusual flags. If, in addition to SYN (or SYN+ACK), there are some 215 | # auxilinary flags that do not modify the very meaning of a packet, 216 | # p0f records this (this can be URG, PUSH, or something else). 217 | # 218 | # Note: ECN flags (ECE and CWR) are ignored and denoted in a separate 219 | # way. ECN is never by default, because some systems can't handle it, 220 | # and it probably does not make much sense to include it in signatures 221 | # right now. 222 | # 223 | # - TCP option segment parsing problems. If p0f fails to decode options 224 | # because of a badly broken packet, it records this fact. 225 | # 226 | # There are several other quirks valid only in RST+ mode, see p0fr.fp for 227 | # more information. Those quirks are unheard of in SYN and SYN+ACK 228 | # modes. 229 | # 230 | # NEW SIGNATURE: Copy "quirks" section literally. 231 | # 232 | # We DO NOT use ToS for fingerprinting. While the original TCP/IP 233 | # fingerprinting research believed this value would be useful for this 234 | # purpose, it is not. The setting is way too often tweaked by network 235 | # devices. 236 | # 237 | # To wildcard MSS, WSS or WSCALE, replace it with '*'. You can also use a 238 | # modulo operator to match any values that divide by nnn - '%nnn' (and, 239 | # as stated above, WSS also supports special values Snn and Tnn). 240 | # 241 | # Fingerprint entry format: 242 | # 243 | # wwww:ttt:D:ss:OOO...:QQ:OS:Details 244 | # 245 | # wwww - window size (can be * or %nnn or Sxx or Txx) 246 | # "Snn" (multiple of MSS) and "Tnn" (multiple of MTU) are allowed. 247 | # ttt - initial TTL 248 | # D - don't fragment bit (0 - not set, 1 - set) 249 | # ss - overall SYN packet size (* has a special meaning) 250 | # OOO - option value and order specification (see below) 251 | # QQ - quirks list (see below) 252 | # OS - OS genre (Linux, Solaris, Windows) 253 | # details - OS description (2.0.27 on x86, etc) 254 | # 255 | # If OS genre starts with '*', p0f will not show distance, link type 256 | # and timestamp data. It is useful for userland TCP/IP stacks of 257 | # network scanners and so on, where many settings are randomized or 258 | # bogus. 259 | # 260 | # If OS genre starts with @, it denotes an approximate hit for a group 261 | # of operating systems (signature reporting still enabled in this case). 262 | # Use this feature at the end of this file to catch cases for which 263 | # you don't have a precise match, but can tell it's Windows or FreeBSD 264 | # or whatnot by looking at, say, flag layout alone. 265 | # 266 | # If OS genre starts with - (which can prefix @ or *), the entry is 267 | # not considered to be a real operating system (but userland stack 268 | # instead). It is important to mark all scanners and so on with -, 269 | # so that they are not used for masquerade detection (also add this 270 | # prefix for signatures of application-induced behavior, such as 271 | # increased window size with Opera browser). 272 | # 273 | # Option block description is a list of comma or space separated 274 | # options in the order they appear in the packet: 275 | # 276 | # N - NOP option 277 | # E - EOL option 278 | # Wnnn - window scaling option, value nnn (or * or %nnn) 279 | # Mnnn - maximum segment size option, value nnn (or * or %nnn) 280 | # S - selective ACK OK 281 | # T - timestamp 282 | # T0 - timestamp with zero value 283 | # ?n - unrecognized option number n. 284 | # 285 | # P0f can sometimes report ?nn among the options. This means it couldn't 286 | # recognize this option (option number nn). It's either a bug in p0f, or 287 | # a faulty TCP/IP stack, or, if the number is listed here: 288 | # 289 | # http://www.iana.org/assignments/tcp-parameters 290 | # 291 | # ...the stack might be simply quite exotic. 292 | # 293 | # To denote no TCP options, use a single '.'. 294 | # 295 | # Quirks section is usually an empty list ('.') of oddities or bugs of this 296 | # particular stack.

More specifically, RFC1323, RFC2018 and 30 | # RFC1644 extensions sometimes show up only if SYN had them enabled. 31 | # 32 | # Also, some silly systems may copy WSS from the SYN packet you've sent, 33 | # in which case, you need to wildcard the value. Use test/sendsyn.c, which 34 | # uses a distinct WSS of 12345, to test for this condition if unsure. 35 | # 36 | # IMPORTANT INFORMATION ABOUT DIFFERENCES IN COMPARISON TO p0f.fp: 37 | # ---------------------------------------------------------------- 38 | # 39 | # - 'A' quirk would be present on almost every signature here. ACK number 40 | # is unusual for SYN packets, but is a commonplace in SYN+ACK packets, 41 | # of course. It is still possible to have a signature without 'A', when 42 | # the ACK flag is present but the value is zero - this, however, is 43 | # very uncommon. 44 | # 45 | # - 'T' quirk would show up on almost all signatures for systems implementing 46 | # RFC1323.

Use test/sendsyn.c for 25 | # "connection refused" and test/sendack.c for "connection dropped" signatures 26 | # - both tools use a distinct WSS of 12345, which is an easy way to tell 27 | # if WSS should be wildcarded. 28 | # 29 | # IMPORTANT INFORMATION ABOUT COMMON IMPLEMENTATION FLAWS 30 | # ------------------------------------------------------- 31 | # 32 | # There are several types of RST packets you will surely encounter. 33 | # Some systems, including most reputable ones, are severily brain-damaged 34 | # and generate some illegal combinations from time to time. This is WAY 35 | # more common than with other packet types, because a broken RST does not 36 | # have any immediately noticable consequences; besides, the RFC793 is fairly 37 | # difficult to comprehend when it comes to this type of responses. 38 | # 39 | # P0f will give you a hint on new RST signatures, but it is your duty to 40 | # diagnose the problem and append the proper description when adding the 41 | # signature. Below is a list of valid and invalid states: 42 | # 43 | # - "Connection refused" message: this is a RST+ACK packet, SEQ number 44 | # set to zero, ACK number non-zero. This is a valid response and 45 | # is denoted by p0f as "refused" (quirk combination: K, 0, A). 46 | # 47 | # There are some very cases when this is incorrectly sent in response 48 | # to an unexpected ACK packet. 49 | # 50 | # - Illegal combination: RST+ACK packet, SEQ number set to zero, ACK 51 | # number zero. This is denoted by p0f as "invalid-K0" (quirk combination: 52 | # K and 0, no A). 53 | # 54 | # - Illegal combination: RST+ACK, SEQ number non-zero, ACK number zero 55 | # or non-zero. This is denoted by p0f as "invalid-K" and 56 | # "invalid-KA", respectively (quirk combinations, K, sometimes A, no 0). 57 | # 58 | # This combination is frequently generated by Cisco routers in certain 59 | # configurations in response to ACK (!). Brain dead, by all means, and 60 | # usually a result of (incorrectly) setting ACK flag on a valid RST packet. 61 | # 62 | # - "Connection dropped": RST, sequence number non-zero, ACK zero or 63 | # non-zero. This is denoted as "dropped" and "dropped 2" respectively 64 | # (quirk combinations: no K, sometimes A, no 0). While the ACK value should 65 | # be zeroed, it is not strictly against the RFC, and some systems either 66 | # leak memory there or set it to the value of SEQ. 67 | # 68 | # The latter variant, with non-zero ACK, is particularly common on 69 | # Windows. 70 | # 71 | # - Ilegal combination: RST, SEQ number zero, ACK zero or non-zero. 72 | # Denoted as "invalid-0" and "invalid-0A". Obviously incorrect, and 73 | # will not have the desired effect. 74 | # 75 | # Ok. That's it. RFC793 does not get much respect nowadays. 76 | # 77 | # IMPORTANT INFORMATION ABOUT DIFFERENCES IN COMPARISON TO p0f.fp: 78 | # ---------------------------------------------------------------- 79 | # 80 | # - Packet size may be wildcarded. The meaning of wildcard is, however, 81 | # hardcoded as 'size > PACKET_BIG' (defined as 100 in config.h). This is 82 | # because some stupid devices (including Ciscos) tend to send back RST 83 | # packets quoting anything you have sent them in ACK packet previously. 84 | # Use sparingly, only if -X confirms the device actually bounces back 85 | # whatever you send. 86 | # 87 | # - A new quirk, 'K', is introduced to denote RST+ACK packets (as opposed 88 | # to plain RST). This quirk is only compatible with this mode. 89 | # 90 | # - A new quirk, 'Q', is used to denote SEQ number equal to ACK number. 91 | # This happens from time to time in RST and RST+ACK packets, but 92 | # is practically unheard of in other modes. 93 | # 94 | # - A new quirk, '0', is used to denote packets with SEQ number set to 0. 95 | # This happens on some RSTs, and is once again unheard of in other modes. 96 | # 97 | # - 'D' quirk is not a bug; some devices send verbose text messages 98 | # describing why a connection got dropped; it's actually suggested 99 | # by RFC1122. Of course, some systems have their own standards, and 100 | # put all kinds of crap in their RST responses (including FreeBSD and 101 | # Cisco). Use -X to examine those values. 102 | # 103 | # - 'A' and 'T' quirks are not an anomaly in certain cases for the reasons 104 | # described in p0fa.fp. 105 | # 106 | 107 | ################################ 108 | # Connection refused - RST+ACK # 109 | ################################ 110 | 111 | 0:255:0:40:.:K0A:Linux:2.0/2.2 (refused) 112 | 0:64:1:40:.:K0A:FreeBSD:4.8 (refused) 113 | 0:64:1:40:.:K0ZA:Linux:recent 2.4 (refused) 114 | 115 | 0:128:0:40:.:K0A:Windows:XP/2000 (refused) 116 | 0:128:0:40:.:K0UA:-Windows:XP/2000 while browsing (refused) 117 | 118 | ###################################### 119 | # Connection dropped / timeout - RST # 120 | ###################################### 121 | 122 | 0:64:1:40:.:.:FreeBSD:4.8 (dropped) 123 | 0:255:0:40:.:.:Linux:2.0/2.2 or IOS 12.x (dropped) 124 | 0:64:1:40:.:Z:Linux:recent 2.4 (dropped) 125 | 0:255:1:40:.:Z:Linux:early 2.4 (dropped) 126 | 0:32:0:40:.:.:Xylan:OmniSwitch / Linksys WAP11 AP (dropped) 127 | 0:64:1:40:.:U:NetIron:load balancer (dropped) 128 | 129 | 0:128:1:40:.:QA:Windows:XP/2000 (dropped 2) 130 | 0:128:1:40:.:A:-Windows:XP/2000 while browsing (1) (dropped 2) 131 | 0:128:1:40:.:QUA:-Windows:XP/2000 while browsing (2) (dropped 2) 132 | 0:128:1:40:.:UA:-Windows:XP/2000 while browsing a lot (dropped 2) 133 | 0:128:1:40:.:.:@Windows:98 (?)
