### GNU AFFERO GENERAL PUBLIC LICENSE
|
||||
|
||||
Version 3, 19 November 2007
|
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc.
|
||||
<https://fsf.org/>
|
||||
|
||||
Everyone is permitted to copy and distribute verbatim copies of this
|
||||
license document, but changing it is not allowed.
|
||||
|
||||
### Preamble
|
||||
|
||||
The GNU Affero General Public License is a free, copyleft license for
|
||||
software and other kinds of works, specifically designed to ensure
|
||||
cooperation with the community in the case of network server software.
|
||||
|
||||
The licenses for most software and other practical works are designed
|
||||
to take away your freedom to share and change the works. By contrast,
|
||||
our General Public Licenses are 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.
|
||||
|
||||
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.
|
||||
|
||||
Developers that use our General Public Licenses protect your rights
|
||||
with two steps: (1) assert copyright on the software, and (2) offer
|
||||
you this License which gives you legal permission to copy, distribute
|
||||
and/or modify the software.
|
||||
|
||||
A secondary benefit of defending all users' freedom is that
|
||||
improvements made in alternate versions of the program, if they
|
||||
receive widespread use, become available for other developers to
|
||||
incorporate. Many developers of free software are heartened and
|
||||
encouraged by the resulting cooperation. However, in the case of
|
||||
software used on network servers, this result may fail to come about.
|
||||
The GNU General Public License permits making a modified version and
|
||||
letting the public access it on a server without ever releasing its
|
||||
source code to the public.
|
||||
|
||||
The GNU Affero General Public License is designed specifically to
|
||||
ensure that, in such cases, the modified source code becomes available
|
||||
to the community. It requires the operator of a network server to
|
||||
provide the source code of the modified version running there to the
|
||||
users of that server. Therefore, public use of a modified version, on
|
||||
a publicly accessible server, gives the public access to the source
|
||||
code of the modified version.
|
||||
|
||||
An older license, called the Affero General Public License and
|
||||
published by Affero, was designed to accomplish similar goals. This is
|
||||
a different license, not a version of the Affero GPL, but Affero has
|
||||
released a new version of the Affero GPL which permits relicensing
|
||||
under this license.
|
||||
|
||||
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 Affero 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. Remote Network Interaction; Use with the GNU General Public License.
|
||||
|
||||
Notwithstanding any other provision of this License, if you modify the
|
||||
Program, your modified version must prominently offer all users
|
||||
interacting with it remotely through a computer network (if your
|
||||
version supports such interaction) an opportunity to receive the
|
||||
Corresponding Source of your version by providing access to the
|
||||
Corresponding Source from a network server at no charge, through some
|
||||
standard or customary means of facilitating copying of software. This
|
||||
Corresponding Source shall include the Corresponding Source for any
|
||||
work covered by version 3 of the GNU General Public License that is
|
||||
incorporated pursuant to the following paragraph.
|
||||
|
||||
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 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 work with which it is combined will remain governed by version
|
||||
3 of the GNU General Public License.
|
||||
|
||||
#### 14. Revised Versions of this License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions
|
||||
of the GNU Affero 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 Affero 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 Affero 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 Affero 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.
|
||||
|
||||
<one line to give the program's name and a brief idea of what it does.>
|
||||
Copyright (C) <year> <name of author>
|
||||
|
||||
This program is free software: you can redistribute it and/or modify
|
||||
it under the terms of the GNU Affero 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 Affero General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU Affero General Public License
|
||||
along with this program. If not, see <https://www.gnu.org/licenses/>.
|
||||
|
||||
Also add information on how to contact you by electronic and paper
|
||||
mail.
|
||||
|
||||
If your software can interact with users remotely through a computer
|
||||
network, you should also make sure that it provides a way for users to
|
||||
get its source. For example, if your program is a web application, its
|
||||
interface could display a "Source" link that leads users to an archive
|
||||
of the code. There are many ways you could offer source, and different
|
||||
solutions will be better for different programs; see section 13 for
|
||||
the specific requirements.
|
||||
|
||||
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 AGPL, see <https://www.gnu.org/licenses/>.

# Sshwifty Web SSH Client
|
||||
|
||||
|
||||
|
||||
Sshwifty is a SSH client that provides a web interface. You can deploy it on
|
||||
your computer or server, so you can access SSH servers via a web browser.
|
||||
|
||||
## Install
|
||||
|
||||
### Binary
|
||||
|
||||
You can download compiled binaries at [Release] section of the page.
|
||||
|
||||
Please noted that those binaries was generated by an automatic proccess, and the
|
||||
author of this project will NOT verify them. You have to try it at your owk
|
||||
risk.
|
||||
|
||||
[release]: https://github.com/niruix/sshwifty/releases
|
||||
|
||||
### Docker Image
|
||||
|
||||
If you have [Docker] installed on your machine, you can directly use the Docker
|
||||
image by executing following command:
|
||||
|
||||
```
|
||||
$ docker run --detach \
|
||||
--restart=always \
|
||||
--publish 8182:8182 \
|
||||
--name sshwifty \
|
||||
niruix/sshwifty:latest
|
||||
```
|
||||
|
||||
[Docker]: https://www.docker.com
|
||||
|
||||
### Compile from source code
|
||||
|
||||
In order to use the source code, you need to install following tools:
|
||||
|
||||
- `git` to download the source code
|
||||
- `npm` to compile front-end application
|
||||
- `go` to compile back-end application
|
||||
|
||||
After you have installed those tools, run following command to download the code
|
||||
to your computer, and start the build proccess:
|
||||
|
||||
```
|
||||
$ git clone https://github.com/niruix/sshwifty
|
||||
$ cd sshwifty
|
||||
$ npm install
|
||||
$ npm run build
|
||||
```
|
||||
|
||||
If the command succeed, you will found the newly generated `sshwifty` binary
|
||||
under current working directory.
|
||||
|
||||
### Deploy on the cloud
|
||||
|
||||
To deploy this project onto the cloud, Google App Engine or Heroku for example,
|
||||
you need to first download the source code, build it locally, then try to deploy
|
||||
it.
|
||||
|
||||
The `npm run build` will build all static files, then automatically call
|
||||
`go generate ./...` to bind those static files directly into program source
|
||||
code. You need those generated source code to get application to function. Also
|
||||
because of this, directly call `go build .` on the newly downloaded souce code
|
||||
will result a failure.
|
||||
|
||||
## Configure
|
||||
|
||||
Sshwifty can be configured though either file or environment variables. By
|
||||
default, the configuration loader will try to load file from default paths
|
||||
first, then try environment variables.
|
||||
|
||||
You can also specifc your own configuration file by setting `SSHWIFTY_CONFIG`
|
||||
environment variables. For example:
|
||||
|
||||
```
|
||||
$ SSHWIFTY_CONFIG=./sshwifty.conf.json ./sshwifty
|
||||
```
|
||||
|
||||
Then, Sshwifty will load the configuration from file `./sshwifty.conf.json`, and
|
||||
will never try for environment variable.
|
||||
|
||||
### Configuration file
|
||||
|
||||
Here is the options that can be used in a configuration file and what it for:
|
||||
|
||||
```
|
||||
{
|
||||
// HTTP Host. Keep it empty to accept request from all hosts
|
||||
"HostName": "localhost",
|
||||
|
||||
// Web interface access password. Set to empty to allow public access
|
||||
"SharedKey": "WEB_ACCESS_PASSWORD",
|
||||
|
||||
// Socks5 proxy. When set, we will try to connect remote through the given
|
||||
// proxy
|
||||
"Socks5": "localhost:1080",
|
||||
|
||||
// Username of the Socks5 server. Set when the Socks5 server requires login
|
||||
"Socks5User": "",
|
||||
|
||||
// Password of the Socks5 server. Set when the Socks5 server requires login
|
||||
"Socks5Password": "",
|
||||
|
||||
// Sshwifty HTTP server, you can set multiple ones to serve on different
|
||||
// ports
|
||||
"Servers": [
|
||||
{
|
||||
// Which local interface this server will be listening
|
||||
"ListenInterface": "0.0.0.0",
|
||||
|
||||
// Which local port this server will be listening
|
||||
"ListenPort": 8182,
|
||||
|
||||
// Timeout of initial request. HTTP handshake must be finished within
|
||||
// this time
|
||||
"InitialTimeout": 3,
|
||||
|
||||
// How long the connection can be idle before the server disconnects the
|
||||
// client
|
||||
"ReadTimeout": 60,
|
||||
|
||||
// How long the server will wait until the client connect is ready to
|
||||
// recieve new data
|
||||
"WriteTimeout": 60,
|
||||
|
||||
// The interval between internal echo requests
|
||||
"HeartbeatTimeout": 20,
|
||||
|
||||
// Forced delay between each request
|
||||
"ReadDelay": 10,
|
||||
|
||||
// Forced delay between each write
|
||||
"WriteDelay": 10,
|
||||
|
||||
// Path to TLS certificate file. Set empty to use HTTP
|
||||
"TLSCertificateFile": "",
|
||||
|
||||
// Path to TLS certificate key file. Set empty to use HTTP
|
||||
"TLSCertificateKeyFile": ""
|
||||
},
|
||||
{
|
||||
"ListenInterface": "0.0.0.0",
|
||||
"ListenPort": 8182,
|
||||
"InitialTimeout": 3,
|
||||
.....
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
`sshwifty.conf.example.json` is an example of a valid configuration file.
|
||||
|
||||
### Environment variables
|
||||
|
||||
Valid environment variables are:
|
||||
|
||||
```
|
||||
SSHWIFTY_HOSTNAME
|
||||
SSHWIFTY_SHAREDKEY
|
||||
SSHWIFTY_SOCKS5
|
||||
SSHWIFTY_SOCKS5_USER
|
||||
SSHWIFTY_SOCKS5_PASSWORD
|
||||
SSHWIFTY_LISTENPORT
|
||||
SSHWIFTY_INITIALTIMEOUT

configuration file.
|

|

Notice: When you use environment variables to configure Sshwifty, then only one
|
||||
Sshwifty HTTP server is then allowed. There is no way to setup mulitple servers
|
||||
here. If you need to serve on multiple ports, use configuratio file instead.
|
||||
|
||||
Be adviced: An invalid value inside following environment variables will cause
|
||||
the value to be reset to default during configuration parsing without warning:

## Contribute
|
||||
|
||||
This is a hobbyist project, meaning I don't have too many time to put into it.
|
||||
|
||||
Upon release (Which is then you're able to read this file), this project will
|
||||
enter maintaining state, which includes doing bug fix and security updates.
|
||||
Adding new features however, is not a part of the state.
|
||||
|
||||
Please don't send pull request. If you need new function, fork it, and maintain
|
||||
it like one of your own. Appreciated!
