Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc.
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.

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.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
Copyright (C)
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read

============
Introduction
------------
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.

===============
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' 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 it's onion service descriptor to the
HSDir system.
A descriptor is uploaded from an instance to it's 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 it's
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.
- **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)
- **6-9 instances** - 10 IPs (selection from all instances)
- **10 or more instances** - 1 IP from a random selection of 10
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

Getting Started
===============
OnionBalance implements `round-robin` like load balancing on top of Tor
hidden services. A typical OnionBalance deployment will incorporate one management
servers and multiple backend application servers.
Architecture
------------
The management server runs the OnionBalance daemon and will regularly publish
hidden service routing information to the Tor network.
The backend application servers / node runs their own standard Tor
hidden service. Client access the public hidden service address are then
routed to one of the backend application servers.
**Management Server**
is the machine running the OnionBalance daemon. It the master hidden
service private key.
This machine can be located geographically isolated from the machines
hosting the hidden service content. It does not need to serve any content.
**Backend Instance**
Each backend application server will run a Tor hidden service. EXPLAIN
.. 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.

Installing and Configuring Tor
------------------------------
Tor is need on the management server and every backend hidden 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 requires at least one system that is running the OnionBalance
management server.
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 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

onionbalance-config Tool
========================
Description
-----------
The ``onionbalance-config`` tool is the fastest way to generate the necessary
keys and config files to get your onion service up and running.
.. code-block:: console
$ onionbalance-config
When called without any arguments, the config generator will run in an
interactive mode and prompt for user input.
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.

====================
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 it's 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
~~~~~~~~~~~~~~~~~~~~~
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).
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
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.

=========
There a many ways to use OnionBalance to increase the scalabiliy, 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.
