Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. 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 them 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 prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. 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. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey 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; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If 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 convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU 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 that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty. 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. 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 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. 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. 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 state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 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 3 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, see . Also add information on how to contact you by electronic and paper mail.

The design involves collating the set of introduction points created by one or more independent Tor onion service instances into a single 'master' descriptor. Overview -------- This tool is designed to allow requests to Tor onion service to be directed to multiple back-end Tor instances, thereby increasing availability and reliability. The design involves collating the set of introduction points created by one or more independent Tor onion service instances into a single 'master' onion service descriptor. The master descriptor is signed by the onion service permanent key and published to the HSDir system as normal. Clients who wish to access the onion service would then retrieve the *master* service descriptor and try to connect to introduction points from the descriptor in a random order. If a client successfully establishes an introduction circuit, they can begin communicating with one of the onion services instances with the normal onion service protocol defined in rend-spec.txt Instance A load-balancing node running an individual onion service. Introduction Point A Tor relay chosen by an onion service instance as a medium-term *meeting-place* for initial client connections. Master Descriptor An onion service descriptor published with the desired onion address containing introduction points for each instance. Management Server Server running OnionBalance which collates introduction points and publishes a master descriptor. Metadata Channel A direct connection from an instance to a management server which can be used for instance descriptor upload and transfer of other data. Retrieving Introduction Point Data ---------------------------------- The core functionality of the OnionBalance service is the collation of introduction point data from multiple onion service instances by the management server. Basic Mode ~~~~~~~~~~ In the 'Basic mode` of operation, the introduction point information is transferred from the onion service instances to the management server via the HSDir system. Each instance runs an onion service with an instance specific permanent key. The instance publishes a descriptor to the DHT at regularly intervals or when its introduction point set changes. On initial startup the management server will load the previously published master descriptor from the DHT if it exists. The master descriptor is used to prepopulate the introduction point set. The management server regularly polls the HSDir system for a descriptor for each of its instances. Currently polling occurs every 10 minutes. This polling period can be tuned for hidden services with shorter or longer lasting introduction points. When the management server receives a new descriptor from the HSDir system, it should before a number of checks to ensure that it is valid: - Confirm that the descriptor has a valid signature and that the public key matches the instance that was requested. - Confirm that the descriptor timestamp is equal or newer than the previously received descriptor for that hidden service instance. This reduces the ability of a HSDir to replay older descriptors for an instance which may contain expired introduction points. - Confirm that the descriptor timestamp is not more than 4 hours in the past. An older descriptor indicates that the instance may no longer be online and publishing descriptors. The instance should not be included in the master descriptor. It should be possible for two or more independent management servers to publish descriptors for a single onion service. The servers would publish independent descriptors which will replace each other on the HSDir system.. Any difference in introduction point selection between descriptors should not impact the end user. Limitations ''''''''''' - A malicious HSDir could replay old instance descriptors in an attempt to include expired introduction points in the master descriptor. When an attacker does not control all of the responsible HSDirs this attack can be mitigated by not accepting descriptors with a timestamp older than the most recently retrieved descriptor. - The management server may also retrieve an old instance descriptor as a result of churn in the DHT. The management server may attempt to fetch the instance descriptor from a different set of HSDirs than the instance published to. - An onion service instance may rapidly rotate its introduction point circuits when subjected to a Denial of Service attack. An introduction point circuit is closed by the onion service when it has received ``max_introductions`` for that circuit. During DoS this circuit rotating may occur faster than the management server polls the HSDir system for new descriptors. As a result clients may retrieve master descriptors which contain no currently valid introduction points. - It is trivial for a HSDir to determine that a onion service is using OnionBalance when in Basic mode. OnionBalance will try poll for instance descriptors on a regular basis. A HSDir which connects to onion services published to it would find that a backend instance is serving the same content as the master service. This allows a HSDir to trivially determine the onion addresses for a service's backend instances. Basic mode allows for scaling across multiple onion service instances with no additional software or Tor modifications necessary on the onion service instance. Basic mode does not hide that a service is using OnionBalance. It also does not significantly protect a service from introduction point denial of service or actively malicious HSDirs. Complex Mode ~~~~~~~~~~~~ In Complex mode, introduction point information is uploaded directly from each instance to the management server via an onion service. The onion service instance does not publishing its onion service descriptor to the HSDir system. A descriptor is uploaded from an instance to its management servers each time Tor generates a new onion service descriptor. A simple daemon running on the onion service instance listens for the event emitted on the Tor control port when a onion service descriptor is generated. The daemon should retrieve the descriptor from the service's local descriptor cache and upload it to one or more management servers configured for that onion service. The protocol for the metadata channel is not yet defined. The metadata channel should authorize connecting instance clients using ``basic`` or ``stealth`` authorization. Multiple management servers for the same onion service may communicate with each other via a hidden service channel. This extra channel can be used to signal when any of the management servers becomes unavailable. A slave management server may begin publishing service descriptors if its master management server is no longer available. Complex mode requires additional software to be run on the service instances. It also requires more complicated communication via a metadata channel. In practice, this metadata channel may be less reliable than the HSDir system. .. note :: The management server communication channel is not implemented yet. The Complex Mode design may be revised significantly before implementation. Complex mode minimizes the information transmitted via the HSDir system and may make it more difficult for a HSDir to determine that a service is using OnionBalance. It also makes it more difficult for an active malicious HSDir to carry out descriptor replay attacks or otherwise interfere with the transfer of introduction point information. The management server is notified about new introduction points shortly after they are created which will result in more recent descriptor data during very high load or denial-of-service situations. Choice of Introduction Points ----------------------------- Tor onion service descriptors can include a maximum of 10 introduction points. OnionBalance should select introduction points so as to uniformly distribute load across the available backend instances. Onionbalance will upload multiple distinct descriptors if you have configured more than 10 instances. - **1 instance** - 3 IPs - **2 instance** - 6 IPs (3 IPs from each instance) - **3 instance** - 9 IPs (3 IPs from each instance) - **4 instance** - 10 IPs (3 IPs from one instance, 2 from each other instance) - **5 instance** - 10 IPs (2 IPs from each instance) - **6-10 instances** - 10 IPs (selection from all instances) - **11 or more instances** - 10 IPs (distinct descriptors - selection from all instances) If running in Complex mode, introduction points can be selected so as to obscure that a service is using OnionBalance. Always attempting to choose 3 introduction points per descriptor may make it more difficult for a passive observer to confirm that a service is running OnionBalance. However behavioral characteristics such as the rate of introduction point rotation may still allow a passive observer to distinguish an OnionBalance service from a standard Tor onion service. Selecting a smaller set of introduction points may impact on performance or reliability of the service. - **1 instance** - 3 IPs - **2 instances** - 3 IPs (2 IPs from one instance, 1 IP from the other instance) - **3 instances** - 3 IPs (1 IP from each instance) - **more than 3 instances** - Select the maximum set of introduction points as outlined previously. It may be advantageous to select introduction points in a non-random manner. The longest-lived introduction points published by a backend instance are likely to be stable. Conversely selecting more recently created introduction points may more evenly distribute client introductions across an instances introduction point circuits. Further investigation of these options should indicate if there is significant advantages to any of these approaches. Generation and Publication of Master Descriptor ----------------------------------------------- The management server should generate a onion service descriptor containing the selected introduction points. This master descriptor is then signed by the actual onion service permanent key. The signed master descriptor should be published to the responsible HSDirs as normal. Clients who wish to access the onion service would then retrieve the 'master' service descriptor and begin connect to introduction points at random from the introduction point list. After successful introduction the client will have created an onion service circuit to one of the available onion services instances and can then begin communicating as normally along that circuit. Next-Generation Onion Services (Prop 224) Compatibility ------------------------------------------------------- In the next-generation onion service proposal (Prop224), introduction point keys will no longer be independent of the instance/descriptor permanent key. The proposal specifies that each introduction point authentication key cross-certifies the descriptor's blinded public key. Each instance must know the master descriptor blinded public key during descriptor generation. One solution is to operate in the Complex mode described previously. Each instance is provided with the descriptor signing key derived from the same master identity key. Each introduction point authentication key will then cross-certify the same blinded public key. The generated service descriptors are not uploaded to the HSDir system. Instead the descriptors are passed to the management server where introduction points are selected and a master descriptor is published. Alternatively a Tor control port command could be implemented to allow a controller to request a onion service descriptor which has each introduction point authentication key cross-certify a blinded public key provided in the control port command. This would remove the need to provide any master service private keys to backend instances. The descriptor signing keys specified in Prop224 are valid for a limited period of time. As a result the compromise of a descriptor signing key does not lead to permanent compromise of the onion service .. TODO: Tidy up this section Implementation ------------------------------------------------------- **TODO** onionbalance-0.1.6/docs/getting-started.rst000066400000000000000000000072571302402152000207350ustar00rootroot00000000000000.. _getting_started: Getting Started =============== OnionBalance implements `round-robin` like load balancing on top of Tor onion services. A typical OnionBalance deployment will incorporate one management servers and multiple backend application servers. Architecture ------------ The management server runs the OnionBalance daemon. OnionBalance combines the routing information (the introduction points) for multiple backend onion services instances and publishes this information in a master descriptor.. .. image:: ../onionbalance.png The backend application servers run a standard Tor onion service. When a client connects to the public onion service they select one of the introduction points at random. When the introduction circuit completes the user is connected to the corresponding backend instance. **Management Server** is the machine running the OnionBalance daemon. It needs to have access to the onion service private key corresponding for the desired onion address. This is the public onion address that users will request. This machine can be located geographically isolated from the machines hosting the onion service content. It does not need to serve any content. **Backend Instance** Each backend application server runs a Tor onion service with a unique onion service key. .. note:: The :ref:`onionbalance-config ` tool can be used to quickly generate keys and config files for your OnionBalance deployment. The OnionBalance tool provide two command line tools: **onionbalance** acts as a long running daemon. **onionbalance-config** is a helper utility which eases the process of creating keys and configuration files for onionbalance and the backend Tor instances. CLI Documentation ~~~~~~~~~~~~~~~~~ .. toctree:: :maxdepth: 1 onionbalance onionbalance-config Installing and Configuring Tor ------------------------------ Tor is need on the management server and every backend onion service instance. Management Server ~~~~~~~~~~~~~~~~~ OnionBalance requires that a recent version of Tor (``>= 0.2.7.1-alpha``) is installed on the management server system. This version might not be available in your operating system's repositories yet. It is recommended that you install Tor from the `Tor Project repositories `_ to ensure you stay up to date with the latest Tor releases. The management server need to have its control port enabled to allow the OnionBalance daemon to talk to the Tor process. This can be done by uncommenting the ``ControlPort`` option in your ``torrc`` configuration file. Alternatively you can replace your ``torrc`` file with the following is suitable for the Tor instance running on the management server: .. literalinclude:: ../onionbalance/data/torrc-server :name: torrc-server :lines: 6- After configuring Tor you should restart your Tor process .. code-block:: console $ sudo service tor reload Backend Instances ~~~~~~~~~~~~~~~~~ Each backend instance should be run a standard onion service which serves your website or other content. More information about configuring onion services is available in the Tor Project's `hidden service configuration guide `_. If you have used the ``onionbalance-config`` tool you should transfer the generated instance config files and keys to the Tor configuration directory on the backend servers. .. literalinclude:: ../onionbalance/data/torrc-instance :name: torrc-instance :lines: 6- After configuring Tor you should restart your Tor process .. code-block:: console $ sudo service tor reload onionbalance-0.1.6/docs/index.rst000066400000000000000000000041751302402152000167330ustar00rootroot00000000000000.. onionbalance documentation master file, created by sphinx-quickstart on Wed Jun 10 13:54:42 2015. You can adapt this file completely to your liking, but it should at least contain the root `toctree` directive. Overview ======== The OnionBalance software allows for Tor hidden service requests to be distributed across multiple backend Tor instances. OnionBalance provides load-balancing while also making onion services more resilient and reliable by eliminating single points-of-failure. - Latest release: |version| (:ref:`changelog`) - GitHub: https://github.com/DonnchaC/onionbalance/ - Issue tracker: https://github.com/DonnchaC/onionbalance/issues - PyPI: https://pypi.python.org/pypi/OnionBalance - IRC: #onionbalance @ OFTC Features ======== OnionBalance is under active development and new features are being added regularly: - Load balancing between up to 60 backend hidden services - Storage of the hidden service private key separate to the hidden service hosts Quickstart ========== Assuming there is no previous configuration in ``/etc/onionbalance``: .. code-block:: console $ onionbalance-config $ sudo cp ./config/master/*.key /etc/onionbalance/ $ sudo cp ./config/master/config.yaml /etc/onionbalance/ $ sudo chown onionbalance:onionbalance /etc/onionbalance/*.key Restart OnionBalance to reload the configuration files. .. code-block:: console $ sudo service onionbalance restart Check the logs. The following warnings are expected: "Error generating descriptor: No introduction points for service ..." .. code-block:: console $ sudo tail -f /var/log/onionbalance/log Copy the ``instance_torrc`` and ``private_key`` files from each of the directories named ``./config/``, ``srv1``, ``srv2``, ... to each of the Tor servers providing the Onion Services. User Guide ========== OnionBalance consists of a long-running daemon and a command-line configuration tool.

The OnionBalance software does not need to be installed on the backend servers which provide the hidden service content (i.e. web site, IRC server etc.). OnionBalance is not yet packaged for most Linux and BSD. The tool can be installed from PyPI or directly from the Git repository: .. code-block:: console # pip install onionbalance or .. code-block:: console $ git clone https://github.com/DonnchaC/onionbalance.git $ cd onionbalance # python setup.py install If you are running Debian unstable or testing, you can install OnionBalance with the following command: .. code-block:: console # apt-get install onionbalance All tagged releases on Github or PyPi are signed with my GPG key: :: pub 4096R/0x3B0D706A7FBFED86 2013-06-27 [expires: 2016-07-11] Key fingerprint = 7EFB DDE8 FD21 11AE A7BE 1AA6 3B0D 706A 7FBF ED86 uid [ultimate] Donncha O'Cearbhaill sub 3072R/0xD60D64E73458F285 2013-06-27 [expires: 2016-07-11] sub 3072R/0x7D49FC2C759AA659 2013-06-27 [expires: 2016-07-11] sub 3072R/0x2C9C6F4ABBFCF7DD 2013-06-27 [expires: 2016-07-11] onionbalance-0.1.6/docs/make.bat000066400000000000000000000161301302402152000164710ustar00rootroot00000000000000@ECHO OFF REM Command file for Sphinx documentation if "%SPHINXBUILD%" == "" ( set SPHINXBUILD=sphinx-build ) set BUILDDIR=_build set ALLSPHINXOPTS=-d %BUILDDIR%/doctrees %SPHINXOPTS% . set I18NSPHINXOPTS=%SPHINXOPTS% . if NOT "%PAPER%" == "" ( set ALLSPHINXOPTS=-D latex_paper_size=%PAPER% %ALLSPHINXOPTS% set I18NSPHINXOPTS=-D latex_paper_size=%PAPER% %I18NSPHINXOPTS% ) if "%1" == "" goto help if "%1" == "help" ( :help echo.Please use `make ^` where ^ is one of echo. html to make standalone HTML files echo. dirhtml to make HTML files named index.html in directories echo. singlehtml to make a single large HTML file echo. pickle to make pickle files echo. json to make JSON files echo. htmlhelp to make HTML files and a HTML help project echo. qthelp to make HTML files and a qthelp project echo. devhelp to make HTML files and a Devhelp project echo. epub to make an epub echo. latex to make LaTeX files, you can set PAPER=a4 or PAPER=letter echo. text to make text files echo. man to make manual pages echo. texinfo to make Texinfo files echo. gettext to make PO message catalogs echo. changes to make an overview over all changed/added/deprecated items echo. xml to make Docutils-native XML files echo. pseudoxml to make pseudoxml-XML files for display purposes echo. linkcheck to check all external links for integrity echo. doctest to run all doctests embedded in the documentation if enabled echo. coverage to run coverage check of the documentation if enabled goto end ) if "%1" == "clean" ( for /d %%i in (%BUILDDIR%\*) do rmdir /q /s %%i del /q /s %BUILDDIR%\* goto end ) REM Check if sphinx-build is available and fallback to Python version if any %SPHINXBUILD% 2> nul if errorlevel 9009 goto sphinx_python goto sphinx_ok :sphinx_python set SPHINXBUILD=python -m sphinx.__init__ %SPHINXBUILD% 2> nul if errorlevel 9009 ( echo. echo.The 'sphinx-build' command was not found.

The ``master`` directory should be stored on the management server while the other ``instance`` directories should be transferred to the respective backend servers. Command-Line Options -------------------- .. autoprogram:: onionbalance.manager:parse_cmd_args() :prog: onionbalance-config Files ----- master/config.yaml This is the configuration file that is used my the OnionBalance management server. master/.key The private key which will become the public address and identity for your hidden service. It is essential that you keep this key secure. master/torrc-server A sample Tor configuration file which can be used with the Tor instance running on the management server. srv/torrc-instance A sample Tor config file which contains the Tor ``HiddenService*`` options needed for your backend Tor instance. srv//private_key Directory containing the private key for you backend hidden service instance. This key is less critical as it can be rotated if lost or compromised. See Also -------- Full documentation for the **OnionBalance** software is available at https://onionbalance.readthedocs.org/ onionbalance-0.1.6/docs/running-onionbalance.rst000066400000000000000000000137511302402152000217320ustar00rootroot00000000000000Running OnionBalance ==================== Description ----------- You can start the OnionBalance management server once all of your backend onion service instances are running. You will need to create a :ref:`configuration file ` which list the backend hidden services and the location of your hidden service keys. .. code-block:: console $ onionbalance -c config.yaml or .. code-block:: console $ sudo service onionbalance start The management server must be left running to publish new descriptors for your onion service. .. note:: Multiple OnionBalance management servers can be run simultaneously with the same master private key and configuration file to provide redundancy. Command-Line Options -------------------- .. autoprogram:: onionbalance.manager:parse_cmd_args() :prog: onionbalance .. _configuration_file_format: Configuration File Format ------------------------- The OnionBalance management server is primarily configured using a YAML configuration file. .. literalinclude:: ../onionbalance/data/config.example.yaml :name: example-config.yaml :language: yaml The ``services`` section of the configuration file contains a list of master onion services that OnionBalance is responsible for. Each ``key`` option specifies the location of the 1024 bit private RSA key for the hidden service. This master private key determines the address that users will use to access your onion service. This private key **must** be kept secure. The location of the private key is evaluated as an absolute path, or relative to the configuration file location. You can use existing Tor hidden service private key with OnionBalance to keep your onion address. Each backend Tor onion service instance is listed by its unique onion address in the ``instances`` list. .. note:: You can replace backend instance keys if they get lost or compromised. Simply start a new backend hidden service under a new key and replace the ``address`` in the config file. If you have used the :ref:`onionbalance-config ` tool you can simply use the generated config file from ``master/config.yaml``. .. note:: By default onionbalance will search for a ``config.yaml`` file in the current working directory. Configuration Options ~~~~~~~~~~~~~~~~~~~~~ The OnionBalance command line options can also be specified in the OnionBalance configuration file. Options specified on the command line take precedence over the related configuration file options: TOR_CONTROL_SOCKET: The location of the Tor unix domain control socket. OnionBalance will attempt to connect to this control socket first before falling back to using a control port connection. (default: /var/run/tor/control) TOR_ADDRESS: The address where the Tor control port is listening. (default: 127.0.0.1) TOR_PORT: The Tor control port. (default: 9051) TOR_CONTROL_PASSWORD: The password for authenticating to a Tor control port which is using the HashedControlPassword authentication method. This is not needed when the Tor control port is using the more common CookieAuthentication method. (default: None) Other options: LOG_LOCATION The path where OnionBalance should write its log file. LOG_LEVEL Specify the minimum verbosity of log messages to output. All log messages equal or higher the the specified log level are output. The available log levels are the same as the --verbosity command line option. REFRESH_INTERVAL How often to check for updated backend hidden service descriptors. This value can be increased if your backend instance are under heavy loaded causing them to rotate introduction points quickly. (default: 600 seconds). PUBLISH_CHECK_INTERVAL How often should to check if new descriptors need to be published for the master hidden service (default: 360 seconds). INITIAL_DELAY How long to wait between starting OnionBalance and publishing the master descriptor. If you have more than 20 backend instances you may need to wait longer for all instance descriptors to download before starting (default: 45 seconds). DISTINCT_DESCRIPTORS Distinct descriptors are used if you have more than 10 backend instances. At the cost of scalability, this can be disabled to appear more like a standard onion service. (default: True) STATUS_SOCKET_LOCATION The OnionBalance service creates a Unix domain socket which provides real-time information about the currently loaded service and descriptors. This option can be used to change the location of this domain socket. (default: /var/run/onionbalance/control) The following options typically do not need to be modified by the end user: REPLICAS How many set of HSDirs to upload too (default: 2). MAX_INTRO_POINTS How many introduction points to include in a descriptor (default: 10) DESCRIPTOR_VALIDITY_PERIOD How long a hidden service descriptor remains valid (default: 86400 seconds) DESCRIPTOR_OVERLAP_PERIOD How long to overlap hidden service descriptors when changing descriptor IDs (default: 3600 seconds) DESCRIPTOR_UPLOAD_PERIOD How often to publish a descriptor, even when the introduction points don't change (default: 3600 seconds) Environment Variables ~~~~~~~~~~~~~~~~~~~~~ ONIONBALANCE_CONFIG Override the location for the OnionBalance configuration file. The loaded configuration file takes precedence over environment variables. Configuration file options will override environment variable which have the same name. ONIONBALANCE_LOG_LOCATION See the config file option. ONIONBALANCE_LOG_LEVEL See the config file option ONIONBALANCE_STATUS_SOCKET_LOCATION See the config file option ONIONBALANCE_TOR_CONTROL_SOCKET See the config file option Files ----- /etc/onionbalance/config.yaml The configuration file, which contains ``services`` entries. config.yaml Fallback location for torrc, if /etc/onionbalance/config.yaml is not found. See Also -------- Full documentation for the **OnionBalance** software is available at https://onionbalance.readthedocs.org/ onionbalance-0.1.6/docs/use-cases.rst000066400000000000000000000035201302402152000175050ustar00rootroot00000000000000Use Cases ========= There a many ways to use OnionBalance to increase the scalability, reliability and security of your onion service. The following are some examples of what is possible. Current Deployments ------------------- **SKS Keyserver Pool** Kristian Fiskerstrand has set up a hidden service `keyserver pool `_ which connects users to one of the available hidden service key servers. Other Examples -------------- - A popular onion service with an overloaded web server or Tor process A service such as Facebook which gets a large number of users would like to distribute client requests across multiple servers as the load is too much for a single Tor instance to handle. They would also like to balance between instances when the 'encrypted services' proposal is implemented [2555]. - Redundancy and automatic failover A political activist would like to keep their web service accessible and secure in the event that the secret police seize some of their servers. Clients should ideally automatically fail-over to another online instances with minimal service disruption. - Secure Onion Service Key storage An onion service operator would like to compartmentalize their permanent onion key in a secure location separate to their Tor process and other services. With this proposal permanent keys could be stored on an independent, isolated system. Research -------- `Ceysun Sucu `_ has analysed OnionBalance and other approaches to hidden service scaling in his masters thesis `Tor\: Hidden Service Scaling `_. The thesis provides a good overview of current approaches. It is a recommended read for those interested in higher performance hidden services.
