+# Continuous Integration Scripts
+
+## Environment Variables
+
+- `ID`: lower-case string that identifies the operating system, for example: `ID=ubuntu`,
+  `ID=centos`. See [os-release(5)] for more information. On macOS, where `os-release` is
+  not available, we emulate it by setting `ID=macos`.
+
+- `ID_LIKE`: space-separated list of operating system identifiers that are closely related
+  to the running OS. See [os-release(5)] for more information. The listed values are used
+  by the CI scripts to select the proper behavior for different platforms and OS flavors.
+
+  Examples:
+
+  - On CentOS, `ID_LIKE="centos rhel fedora linux"`
+  - On Ubuntu, `ID_LIKE="ubuntu debian linux"`
+
+- `VERSION_ID`: identifies the operating system version, excluding any release code names.
+  See [os-release(5)] for more information. Examples: `VERSION_ID=42`, `VERSION_ID=22.04`.
+
+- `JOB_NAME`: defines the type of the current CI job. Depending on the job type, the CI
+  scripts can perform different tasks.
+
+  Supported values:
+
+  - empty: default build task
+  - `code-coverage`: debug build with tests and code coverage analysis
+  - `limited-build`: only a single debug build with tests
+
+- `CACHE_DIR`: directory containing cached files from previous builds, e.g., a compiled
+  version of ndn-cxx. If not set, `/tmp` is used.
+
+- `DISABLE_ASAN`: disable building with AddressSanitizer. This is automatically set for
+  the `code-coverage` job type.
+
+[os-release(5)]: https://www.freedesktop.org/software/systemd/man/os-release.html

+#!/usr/bin/env python
+# encoding: utf-8
+#
+# partially based on boost.py written by Gernot Vormayr
+# written by Ruediger Sonderfeld <ruediger@c-plusplus.de>, 2008
+# modified by Bjoern Michaelsen, 2008
+# modified by Luca Fossati, 2008
+# rewritten for waf 1.5.1, Thomas Nagy, 2008
+# rewritten for waf 1.6.2, Sylvain Rouquette, 2011
+
+'''
+
+This is an extra tool, not bundled with the default waf binary.
+To add the boost tool to the waf file:
+$ ./waf-light --tools=compat15,boost
+	or, if you have waf >= 1.6.2
+$ ./waf update --files=boost
+
+When using this tool, the wscript will look like:
+
+	def options(opt):
+		opt.load('compiler_cxx boost')
+
+	def configure(conf):
+		conf.load('compiler_cxx boost')
+		conf.check_boost(lib='system filesystem')
+
+	def build(bld):
+		bld(source='main.cpp', target='app', use='BOOST')
+
+Options are generated, in order to specify the location of boost includes/libraries.
+The `check_boost` configuration function allows to specify the used boost libraries.
+It can also provide default arguments to the --boost-mt command-line arguments.
+Everything will be packaged together in a BOOST component that you can use.
+
+When using MSVC, a lot of compilation flags need to match your BOOST build configuration:
+ - you may have to add /EHsc to your CXXFLAGS or define boost::throw_exception if BOOST_NO_EXCEPTIONS is defined.
+   Errors: C4530
+ - boost libraries will try to be smart and use the (pretty but often not useful) auto-linking feature of MSVC
+   So before calling `conf.check_boost` you might want to disabling by adding
+		conf.env.DEFINES_BOOST += ['BOOST_ALL_NO_LIB']
+   Errors:
+ - boost might also be compiled with /MT, which links the runtime statically.
+   If you have problems with redefined symbols,
+		self.env['DEFINES_%s' % var] += ['BOOST_ALL_NO_LIB']
+		self.env['CXXFLAGS_%s' % var] += ['/MD', '/EHsc']
+Passing `--boost-linkage_autodetect` might help ensuring having a correct linkage in some basic cases.

+### GNU GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 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 General Public License is a free, copyleft license for
+software and other kinds of works.
+
+The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom
+to share and change all versions of a program--to make sure it remains
+free software for all its users. We, the Free Software Foundation, use
+the GNU General Public License for most of our software; it applies
+also to any other work released this way by its authors. You can apply
+it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you
+have certain responsibilities if you distribute copies of the
+software, or if you modify it: responsibilities to respect the freedom
+of others.
+
+For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the
+manufacturer can do so. This is fundamentally incompatible with the
+aim of protecting users' freedom to change the software. The
+systematic pattern of such abuse occurs in the area of products for
+individuals to use, which is precisely where it is most unacceptable.
+Therefore, we have designed this version of the GPL to prohibit the
+practice for those products. If such problems arise substantially in
+other domains, we stand ready to extend this provision to those
+domains in future versions of the GPL, as needed to protect the
+freedom of users.
+
+Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish
+to avoid the special danger that patents applied to a free program
+could make it effectively proprietary. To prevent this, the GPL
+assures that patents cannot be used to render the program non-free.
+
+The precise terms and conditions for copying, distribution and
+modification follow.
+
+### TERMS AND CONDITIONS
+
+#### 0. Definitions.
+
+"This License" refers to version 3 of the GNU General Public License.
+
+"Copyright" also means copyright-like laws that apply to other kinds
+of works, such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of
+an exact copy. The resulting work is called a "modified version" of
+the earlier work or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user
+through a computer network, with no transfer of a copy, is not
+conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to
+the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+#### 1. Source Code.
+
+The "source code" for a work means the preferred form of the work for
+making modifications to it. "Object code" means any non-source form of
+a work.
+
+A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+The Corresponding Source need not include anything that users can
+regenerate automatically from other parts of the Corresponding Source.
+
+The Corresponding Source for a work in source code form is that same
+work.
+
+#### 2. Basic Permissions.
+
+All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+You may make, run and propagate covered works that you do not convey,
+without conditions so long as your license otherwise remains in force.
+You may convey covered works to others for the sole purpose of having
+them make modifications exclusively for you, or provide you with
+facilities for running those works, provided that you comply with the
+terms of this License in conveying all material for which you do not
+control copyright. Those thus making or running the covered works for
+you must do so exclusively on your behalf, under your direction and
+control, on terms that prohibit them from making any copies of your
+copyrighted material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the
+conditions stated below. Sublicensing is not allowed; section 10 makes
+it unnecessary.
+
+#### 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such
+circumvention is effected by exercising rights under this License with
+respect to the covered work, and you disclaim any intention to limit
+operation or modification of the work as a means of enforcing, against
+the work's users, your or third parties' legal rights to forbid
+circumvention of technological measures.
+
+#### 4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+#### 5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these
+conditions:
+
+-   a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+-   b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under
+    section 7. This requirement modifies the requirement in section 4
+    to "keep intact all notices".
+-   c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy. This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged. This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+-   d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+#### 6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of
+sections 4 and 5, provided that you also convey the machine-readable
+Corresponding Source under the terms of this License, in one of these
+ways:
+
+-   a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+-   b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the Corresponding
+    Source from a network server at no charge.
+-   c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source. This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+-   d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge. You need not require recipients to copy the
+    Corresponding Source along with the object code. If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source. Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+-   e) Convey the object code using peer-to-peer transmission,
+    provided you inform other peers where the object code and
+    Corresponding Source of the work are being offered to the general
+    public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal,
+family, or household purposes, or (2) anything designed or sold for
+incorporation into a dwelling. In determining whether a product is a
+consumer product, doubtful cases shall be resolved in favor of
+coverage. For a particular product received by a particular user,
+"normally used" refers to a typical or common use of that class of
+product, regardless of the status of the particular user or of the way
+in which the particular user actually uses, or expects or is expected
+to use, the product. A product is a consumer product regardless of
+whether the product has substantial commercial, industrial or
+non-consumer uses, unless such uses represent the only significant
+mode of use of the product.
+
+"Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to
+install and execute modified versions of a covered work in that User
+Product from a modified version of its Corresponding Source. The
+information must suffice to ensure that the continued functioning of
+the modified object code is in no case prevented or interfered with
+solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or
+updates for a work that has been modified or installed by the
+recipient, or for the User Product in which it has been modified or
+installed. Access to a network may be denied when the modification
+itself materially and adversely affects the operation of the network
+or violates the rules and protocols for communication across the
+network.
+
+Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+#### 7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders
+of that material) supplement the terms of this License with terms:
+
+-   a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+-   b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+-   c) Prohibiting misrepresentation of the origin of that material,
+    or requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+-   d) Limiting the use for publicity purposes of names of licensors
+    or authors of the material; or
+-   e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+-   f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions
+    of it) with contractual assumptions of liability to the recipient,
+    for any liability that these contractual assumptions directly
+    impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions; the
+above requirements apply either way.
+
+#### 8. Termination.
+
+You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+#### 9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run
+a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+#### 10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+#### 11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned
+or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the
+scope of its coverage, prohibits the exercise of, or is conditioned on
+the non-exercise of one or more of the rights that are specifically
+granted under this License. You may not convey a covered work if you
+are a party to an arrangement with a third party that is in the
+business of distributing software, under which you make payment to the
+third party based on the extent of your activity of conveying the
+work, and under which the third party grants, to any of the parties
+who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by
+you (or copies made from those copies), or (b) primarily for and in
+connection with specific products or compilations that contain the
+covered work, unless you entered into that arrangement, or that patent
+license was granted, prior to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+#### 12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under
+this License and any other pertinent obligations, then as a
+consequence you may not convey it at all. For example, if you agree to
+terms that obligate you to collect a royalty for further conveying
+from those to whom you convey the Program, the only way you could
+satisfy both those terms and this License would be to refrain entirely
+from conveying the Program.
+
+#### 13. Use with the GNU Affero General Public License.
+
+Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+#### 14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions
+of the GNU General Public License from time to time. Such new versions
+will be similar in spirit to the present version, but may differ in
+detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies that a certain numbered version of the GNU General Public
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that numbered version or
+of any later version published by the Free Software Foundation. If the
+Program does not specify a version number of the GNU General Public
+License, you may choose any version ever published by the Free
+Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions
+of the GNU General Public License can be used, that proxy's public
+statement of acceptance of a version permanently authorizes you to
+choose that version for the Program.
+
+Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+#### 15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
+WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
+LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
+A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
+PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
+DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+#### 16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR

+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 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 <https://www.gnu.org/licenses/>.
+
+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:
+
+        <program>  Copyright (C) <year>  <name of author>
+        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 <https://www.gnu.org/licenses/>.
+
+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

-Installation:
-
-1: Getting NLSR: 
-
-https://github.com/NDN-Routing/NLSR0.0
-
-2: run make to compile. 
-
-3: Start ccnx daemon (ccnd) and Repo (ccnr).
-
-4: Add '/ndn/keys' route to your neighboring testbed nodes. 
-This can be done by adding routes in your ccnd.conf to all neigbors,
-e.g.
-	add /ndn/keys udp 10.0.XX.XX 
-	add /ndn/keys udp 10.0.YY.YY ...  
-	add	/ndn/keys udp 10.0.ZZ.ZZ
-
-5: Create your keys and publish them through repo. Please have
-	a look at https://github.com/named-data/ndn-testbed-key-suite for details. 
-
-6: create a nlsr configuration file, have a look at
-	macbook.conf and 'Configuration Parameters' section  for details 
-
-7: start nlsr 
-
-
-Configuration Parameter: 
-
-1. router-name </name/prefix/of/the/router> 
-It is a required configuration parameter that is used to set the router name.
-Name prefix of the router must start with `/ndn' and followed by a strict
-hierarchical order of name components up to the hostname of the router. For
-e.g. if router has a hostname host.dept.org.edu pollux.cs.memphis.edu then the
-router name can be `/ndn/org.edu/dept/host..
-
-2. ccnneighbor </name/prefix/of/neighbor> [neighbor_ip_addrr] 
-This parameter is used to configure the neighboring router. Name prefix of a
-neighbor must start with `/ndn. and followed by a strict hierarchical order of
-name component as mentioned for router-name. If a router has a neighbor having
-hostname `neighbor.dept.org.edu' then configuration command would be
-`ccnneighbor /ndn/org.edu/dept/neighbor. The optional parameter,
-[neighbor_ip_addrr], can be provided for explicitly connecting to a given 
-IP. This is useful if there is no entry of the hostname in the DNS. 
-
-3. ccnname </name/prefix/to/be/advertised> 
-ccnname is used to advertise the name prefix of the services hosted by the
-router. Name prefix must follow the ccnx naming convention.
-
-4. topo-prefix <name/prefix/of/repo/topo> 
-It is used to configure the topological prefix of the `sync. slice created for
-nlsr in a repo. Prefix must follow the ccnx naming convention. Default value
-for topo prefix is `/ndn/routing/nlsr'
-
-5. slice-prefix <name/prefix/of/repo/slice>
-This parameter is used to set the sync's slice prefix. All nlsr nodes `must'
-have the same slice prefix and must follow the ccnx naming convention. Default
-value for slice prefix is `/ndn/routing/nlsr/LSA'
-
-6. lsa-refresh-time <sec> 
-It is the time in seconds, after which router will refresh its LSAs. Default
-value = 1800 sec, Min = 240 sec
-
-7. router-dead-interval <sec> 
-It is the time after which router will consider its neighbor dead if it does
-not hear anything for that amount of time. If an LSA generated by neighbor has
-a lifetime greater than router-dead-interval then router will simply discard
-the LSA and update name prefix table, routing table and ccnd FIB accordingly.
-Default value = 3600 sec, Min = 360 sec.
-
-8. interest-retry <number> 
-interest-retry is maximum number of times a router will send same interest if
-the interest is timed out. Default = 3, Min =1 and Max = 10
-
-9. interest-resend-time <sec>
-When an interest is timed out, NLSR waits for `interest-resend-time. before
-sending another interest. The interest is retransmitted up to the value of
-`interest-retry.. If the interest doesn.t get satisfied during this time the
-neighbor will be considered as dead. Default value = 15 sec, Min = 1 sec, Max =
-60 sec 
-
-10. max-faces-per-prefix <number>
-By default NLSR calculates and add faces for all available faces to a prefix.
-Number of faces can be restricted with this parameter, if this is configured
-NLSR will add <number> or faces per prefixes in ccnd FIB.
-
-11. debug <on/off> 
-Enable nlsr debugging by printing out detail messages on the standard output.
-By default it is off. 
-
-12. logdir </directory/for/logging/> 
-NLSR will start writing log in logdir folder. If logdir is not configured NLSR
-will create a log directory name nlsrLog in user home directory and write log
-into that folder.
-
-13. tunnel-type <udp | tcp> 
-This is used to specify the tunnel type that NLSR should create for building an
-overlay network. By default NLSR creates udp tunnels.
-
-**Following Commands are only required for hyperbolic routing**
-
-14. hyperbolic-routing <on|dry_run> 
-This option enables hyperbolic routing. With option on, link state routing
-doesn't work while with dry_run option route is calculated by Link State 
-routing and hyperbolic routes are just recorded only in log file.Following 
-field is required if hyperbolic routing is on. 
-
-15. hyperbolic-cordinate <radius> <theta> 
-Polar coordinates of a node in a form of radius and theta. Currently, calculation 
-of the polar coordinates is an offline process and done by 
-the operator of a site. 
-
-** Hyperbolic Commands End here **
-
-16. keystore-path </path/to/keystore/file name(.ccnx_keystore)>
-Path to the keystore. The keystore folder is usually created  by
-ccninitkeystore. Keys in this folder will be used by NLSR to sign the packets. 
-
-17. root-key-prefix </key/prefix>   
-Name prefix of the root key; the site key should be signed by this key.  
-e.g. root-key-prefix /ndn/keys
-
-18. site-name </name/prefix/of/site> 
-Name of the site of which this router is a part. 
-
-19. network </name/of/network>
-Name of the networks router belongs to

+
+## Overview
+
+NLSR is a routing protocol for Named Data Networking (NDN) that populates the Routing Information
+Base (RIB) of an NDN router, such as [NFD](https://github.com/named-data/NFD). NLSR continues to
+evolve alongside the core [NDN protocol](https://docs.named-data.net/NDN-packet-spec/current/).
+
+The main design goal of NLSR is to provide a routing protocol to populate NDN's RIB.
+NLSR calculates the routing table using link-state or hyperbolic routing and produces
+multiple faces for each reachable name prefix in a single authoritative domain. NLSR
+will continue to evolve over time to include neighbor discovery and to become a full
+fledged inter-domain routing protocol for NDN.
+
+NLSR was mainly developed by members of the NSF-sponsored [NDN project team](
+https://named-data.net/project/participants/). See [`AUTHORS.md`](AUTHORS.md) for details.

+=========================
+
+.. toctree::
+..
+
+Getting Source
+--------------
+
+- `GitHub NLSR repository <https://github.com/named-data/NLSR>`__
+
+Installation
+------------
+
+:doc:`INSTALL`
+
+Important Notes About Configuration
+-----------------------------------
+
+Since v0.4.0, NLSR no longer creates Faces for the neighbors that are
+specified in ``nlsr.conf``. Instead, it relies on the pre-existence of
+the Faces in NFD. NLSR will obtain this information from NFD, and
+configure its neighbors using this information.
+
+For users who were relying on NLSR to automagically configure their networks,
+this must now be done with ``nfdc``. See ``man nfdc`` for its documentation
+(`online version <https://docs.named-data.net/NFD/current/manpages/nfdc.html>`__).
+
+Configuration
+-------------
+
+After installing NLSR from source, you need to create a configuration file for
+NLSR. Please take a look at :doc:`manpages/nlsr.conf` for a sample configuration. For
+details on configuring a router, please refer to :doc:`ROUTER-CONFIG`. For details on
+security configuration, please refer to :doc:`SECURITY-CONFIG`.
+
+Running
+-------
+
+Run nlsr with the following command:
+
+::
+
+    nlsr
+
+NLSR will look for the default configuration file, ``nlsr.conf``, in the current directory.
+
+You can also run ``nlsr -f`` with the absolute path of the configuration file:
+
+::
+
+    nlsr -f /usr/local/etc/ndn/nlsr.conf
+
+Logging
+-------
+
+NLSR uses the ndn-cxx logging facility. All levels listed below the selected log-level
+value are enabled.
+
+::
+
+    Valid values:
+
+      TRACE    trace messages (most verbose)
+      DEBUG    debugging messages
+      INFO     informational messages
+      WARN     warning messages
+      ERROR    error messages
+      FATAL    fatal (will be logged unconditionally)
+
+To obtain logs for NLSR, set the ``NDN_LOG`` environment variable with the correct prefix
+and log-level settings. For example, running the following command will display all log
+messages in NLSR with a DEBUG level or below.
+
+.. code-block:: sh
+
+    NDN_LOG='nlsr.*=DEBUG' nlsr
+
+If the user is presented with an error message "User does not have read and write
+permission on the directory" it can be circumvented by running the application with sudo:
+
+.. code-block:: sh
+
+    sudo env NDN_LOG='nlsr.*=DEBUG' nlsr
+
+See ``man ndn-log`` for more details (`online version
+<https://docs.named-data.net/ndn-cxx/current/manpages/ndn-log.html>`__).

+Router Configuration
+====================
+
+.. toctree::
+..
+
+Example network and sample configuration
+----------------------------------------
+
+Assume that three routers in the same network, but at three different sites
+(``memphis.edu``, ``arizona.edu``, and ``colostate.edu``), are connected to each other to
+construct the following topology:
+
+::
+
+                        +-------------------------------------+
+                        | /ndn/edu/memphis/%C1.Router/router1 |
+                        +-------------------------------------+
+                            / 11                      12\
+                           /                             \
+          route-cost = 25 /                               \ route-cost = 30
+                         /                                 \
+                     17 /                                   \ 13
+    +-----------------------------------+ 7              10 +-------------------------------------+
+    |/ndn/edu/arizona/%C1.Router/router3|-------------------|/ndn/edu/colostate/%C1.Router/router2|
+    +-----------------------------------+   route-cost = 28 +-------------------------------------+
+
+                          Figure: Network Topology
+
+The number represents the connecting face id. For example,
+``/ndn/edu/memphis/%C1.Router/router1`` is connected to
+``/ndn/edu/arizona/%C1.Router/router3`` via face 11 and the route cost is 25. To reach
+``/ndn/edu/colostate/%C1.Router/router2`` via face 12, the route cost is 30.
+
+We will walk through setting up the faces and creating the configuration file for
+``/ndn/edu/memphis/%C1.Router/router1``.
+
+It is recommended to configure security as described at :doc:`SECURITY-CONFIG`, before
+starting router configuration.
+
+Step 1. Ensuring nfd is running
+-------------------------------
+
+Type the following in the terminal:
+
+::
+
+    nfd-status
+
+If you see ``error while connecting to the forwarder (No such file or directory)``,
+``nfd`` is not running. Follow the instructions in `Getting started with NFD
+<https://docs.named-data.net/NFD/current/INSTALL.html>`_ to run nfd.
+
+Since v0.4.0, NLSR no longer creates Faces for the neighbors that are
+specified in ``nlsr.conf``. Instead, it relies on the pre-existence of
+the Faces in NFD. NLSR will obtain this information from NFD, and
+configure its neighbors using this information.
+
+To create faces it is now necessary to use the ``nfdc`` command. See ``man nfdc`` for
+its documentation (`online version <https://docs.named-data.net/NFD/current/manpages/nfdc.html>`__).
+
+Step 2. Determining FaceUri
+---------------------------
+
+Assume that ``/ndn/edu/arizona/%C1.Router/router3`` has hostname ``router3.arizona.edu`` and
+``/ndn/edu/colostate/%C1.Router/router2`` has IP address ``79.123.10.145``.
+``/ndn/edu/memphis/%C1.Router/router1`` will consider FaceUri
+``udp4://router3.arizona.edu`` for router ``/ndn/edu/arizona/%C1.Router/router3`` and
+FaceUri ``udp4://79.123.10.145`` for router ``/ndn/edu/colostate/%C1.Router/router2``.
+
+Step 3: Creating configuration file
+-----------------------------------
+
+Now, assume that ``/ndn/memphis.edu/router1`` wants to advertise three name prefixes
+(``/ndn/memphis/sports/basketball/grizzlies``, ``/ndn/memphis/entertainment/blues``,
+``/ndn/news/memphis/politics/lutherking``). The configuration file with the necessary
+configuration commands follows:
+
+::
+
+    ; nlsr.conf starts here
+    ; the general section contains all the general settings for router
+
+    general
+    {
+        ; mandatory configuration command section network, site and router
+        network /ndn/         ; name of the network the router belongs to in ndn URI format
+        site /edu/memphis/    ; name of the site the router belongs to in ndn URI format
+        router /%C1.Router/router1    ; name of the network the router belongs to in ndn URI format
+
+        ; lsa-refresh-time is the time in seconds, after which router will refresh its LSAs
+        lsa-refresh-time 1800      ; default value 1800. Valid values 240-7200
+

+        prefix /ndn/memphis/entertainment/blues
+        prefix /ndn/news/memphis/politics/lutherking
+    }
+
+By default NLSR's sequence file directory is set to ``/var/lib/nlsr/``. User must create this
+directory before starting NLSR. Since this is a system directory, NLSR must either be executed
+as root, or NLSR can be run as user "nlsr" after configuring the filesystem to grant "nlsr"
+read and write permissions. If user lacks permissions, the following error will occur:
+
+::
+
+    User does not have read and write permission on the directory
+    Error in configuration file processing! Exiting from NLSR
+
+To avoid this, the directory can be set in a user-owned directory. For example:
+
+::
+
+    general
+    {
+      ...
+
+      state-dir /home/username/nlsr/log  ; path for sequence directory and other dynamic changes (Absolute path)
+
+    }
+    ...
+
+The user will encounter errors such as the following if security is not configured:
+
+::
+
+    Cannot read certificate from file: /home/username/NLSR/root.cert
+
+To get rid of this and similar errors relating to security one has to configure security
+as described in :doc:`SECURITY-CONFIG`. Security can be disabled for testing purposes as follows:
+
+::
+
+    ...
+    trust-anchor
+    {
+      type any
+      ;file-name "root.cert"
+    }
+    ...
+    trust-anchor
+    {
+      type any
+      ;file-name "site.cert"
+    }
+    ; cert-to-publish "root.cert"
+    ; cert-to-publish "router.cert"
+    ; cert-to-publish "site.cert"
+    ; cert-to-publish "router.cert"
+
+Or by simply replacing the whole security section with:
+
+::
+
+    security
+    {
+      validator
+      {
+        trust-anchor
+        {
+          type any
+        }
+      }
+      prefix-update-validator
+      {
+        trust-anchor
+        {
+          type any
+        }
+      }
+    }
+
+Step 4: Running NLSR on /ndn/memphis.edu/router1
+-------------------------------------------------
+
+Assuming the configuration file is saved as ``nlsr.conf``, type the following to run nlsr:
+
+::
+
+    $ nlsr -f nlsr.conf
+
+NLSR will look for nlsr.conf in the current directory. If nlsr.conf is not in the current
+directory, please provide the absolute path with the file name as the value. If
+``nlsr.conf`` resides in ``/home/ndnuser/configuration`` directory, type ``nlsr -f
+/home/ndnuser/configuration/nlsr.conf`` to run nlsr.
+
+The same process needs to be followed for ``/ndn/arizona.edu/router3`` and
+``/ndn/colostate.edu/router2`` to run NLSR on these routers.
+
+Expected Output
+----------------
+
+Assuming that all three routers are configured correctly and routing has converged,
+``nfd-status`` in ``/ndn/edu/colostate/%C1.Router/router2`` will have the following (or similar)
+entries for the name advertised by ``/ndn/edu/memphis/%C1.Router/router1``:
+
+RIB:
+
+::
+
+    /ndn/memphis/entertainment/blues route={faceid=17 (origin=128 cost=25 ChildInherit), faceid=7 (origin=128 cost=58 ChildInherit)}
+    /ndn/memphis/sports/basketball/grizzlies route={faceid=17 (origin=128 cost=25 ChildInherit), faceid=7 (origin=128 cost=58 ChildInherit)}
+    /ndn/news/memphis/politics/lutherking route={faceid=17 (origin=128 cost=25 ChildInherit, faceid=7 (origin=128 cost=58 ChildInherit)}
+
+This output can be seen by typing ``nfdc route list`` in the terminal.  Please refer to the
+network figure for face IDs.

+Certificate Publishing
+----------------------
+
+In a network, every router should have the root certificate configured as a trust
+anchor. For each site, at least one router should publish the site certificate, and at
+least one router should publish the certificate of the site operator. Each router should
+publish its own certificate. All this information should be explicitly specified in the
+nlsr.conf file. For example, the following configuration file indicates that NLSR should
+publish the site certificate and the router certificate:
+
+::
+
+    ...

+A beginners guide to installing and testing NLSR on Fedora
+==========================================================
+
+:Authors:  David Arjona-Villicaña, Octavio Renteria-Vidales, Ashlesh Gawande
+:Date:     November, 2018
+:Abstract: This is an easy to follow guide on how to install and test the NLSR routing protocol for NDN using two Fedora 28 machines. The commands and the paths used in this guide have been tested only in Fedora, although a similar procedure should be used for other linux systems. Specifically, the testing section (§ `5 <#test>`__) is platform independent. Therefore users who have NLSR already installed may skip to this section. Since neither NDN, NLSR nor Fedora are static software developments, it is expected that some commands and features in this guide will change over time. However, this guide is as accurate as it could be at the time it was published.
+
+.. role:: raw-latex(raw)
+   :format: latex
+
+
+.. _intro:
+
+1. Introduction
+===============
+
+The following instructions are based on the information provided at the
+Named Data Networking project web page [NDNmain]_.
+Before installing NLSR it is necessary to install different libraries and
+programs: ndn-cxx, NFD, ChronoSync [optional], ndn-svs [optional] and PSync.
+This document describes the necessary steps to correctly install these
+programs (§ `2 <#ndncxx>`__, `3 <#nfd>`__ and `4 <#nlsr>`__) and a brief
+guide on how to configure and test NLSR using a simple two-node
+network (§ `5 <#test>`__).
+
+Many of the commands in this guide need to be executed as *root*.
+Starting from Fedora 28, there is no need to set a root user
+[Kolman2018]_. However it is possible to define it,
+using the following command:
+
+::
+
+      $ sudo -i
+
+And then using the ``passwd`` command to set up a password. After setting
+up the root user, it is possible to become root by employing the
+following command and providing the root password when prompted:
+
+::
+
+      $ su -
+
+Fedora employs the ``dnf`` command to install and verify installed
+packages. The following commands may become useful during the
+installation process and should be executed as root:
+
+-  To verify that all installed packages are up to date
+
+   ::
+
+       $ dnf update
+
+-  To verify if a package is already installed in the system
+
+   ::
+
+       $ dnf list --installed <package-name>
+
+-  To search for information about a package or family of packages (not
+   necessarily installed in the system).
+
+   ::
+
+       $ dnf info <package-name>
+
+-  To install a package in the system.
+
+   ::
+
+       $ dnf install <package-name>
+
+It is also a good installation practice to download and install all the
+NDN programs in a common directory. Therefore, it is recommended to
+create a directory at the home directory where all the following
+programs may get installed. The name of this directory is not important.
+However, the following are provided as suggestions: project, NDNproject,
+NDNprograms. Each of the programs in the following sections should be
+downloaded to their own directory using the ``git`` command, and then
+compiled in this directory.
+
+.. _ndncxx:
+
+2. Installing ndn-cxx
+=====================
+
+2.1 Before installing ndn-cxx
+-----------------------------
+
+An updated list of the packages and programs that need to be installed
+before installing ndn-cxx, is provided at [NDN-cxx]_.
+This list is also reproduced below with the commands to verify that all
+the packages have been installed in the system. The following commands
+should be run as root:
+
+#. gcc and gcc-c++
+
+   ::
+
+       $ dnf list --installed gcc
+       $ dnf list --installed gcc-c++
+
+#. Python version 3.8 or later
+
+   ::
+
+       $ python3 -V
+
+#. SQLite 3.x
+
+   ::
+
+       $ dnf list --installed sqlite-devel
+
+#. OpenSSL version 1.1.1 or later
+
+   ::
+
+       $ dnf list --installed openssl-devel
+
+#. pkgconf that replaces pkg-config
+
+   ::
+
+       $ dnf list --installed pkgconf*
+
+#. Boost libraries version 1.71.0 or later
+
+   ::
+
+       $ dnf list --installed boost-devel
+
+#. git
+
+   ::
+
+       $ dnf list --installed git
+
+#. doxygen (optional)
+
+   ::
+
+       $ dnf list --installed doxygen
+
+#. graphviz (optional)
+
+   ::
+
+       $ dnf list --installed graphviz
+
+#. python3-pip (optional)
+
+   ::
+
+       $ dnf list --installed python3-pip
+
+#. After verifying that the python3-pip package has been installed, it
+   is necessary to run the following command:
+
+   ::
+
+       $ pip install sphinx sphinxcontrib-doxylink
+
+2.2 Downloading and installing ndn-cxx
+--------------------------------------
+
+The ``git`` command allows to download the ndn-cxx library in its own
+folder, also called *ndn-cxx*. Therefore it is recommended to execute
+this command at the directory created at § `1 <#intro>`__:
+
+::
+
+      $ git clone --depth 1 https://github.com/named-data/ndn-cxx.git
+
+Move to the ndn-cxx directory:
+
+::
+
+      $ cd ndn-cxx
+
+Use the following command to verify that everything is ready to compile.
+If an error message displays, it is necessary to fix it before
+continuing:
+
+::
+
+      $ ./waf configure --with-examples
+
+Compile the ndn-cxx library and install the compiled files at the
+system's directories:
+
+::
+
+      $ ./waf
+      $ sudo ./waf install
+
+2.3 Configuring ndn-cxx
+-----------------------
+
+The commands in this subsection need to be run as root. First, it is
+necessary to create file *local.conf*, which contains a line with the
+location for the ndn-cxx library:
+
+::
+
+      $ echo /usr/local/lib64 >> /etc/ld.so.conf.d/local.conf
+
+The following command configures the libraries:
+
+::
+
+      $ ldconfig -v | grep ndn
+
+This command should display a line similar to the following:
+
+::
+
+         libndn-cxx.so.0.6.1 -> libndn-cxx.so.0.6.1
+
+Configure the NDN path:
+
+::
+
+      $ echo export PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig >> /etc/profile.d/ndn.sh
+
+After this command has been executed, it is necessary to apply the
+changes by either logging out and back in, and then running the
+following command:
+
+::
+
+      $ printenv | grep PKG
+
+Or by executing the following command:
+
+::
+
+      $ ./etc/profile.d/ndn.sh
+
+For more information and examples about how to compile and configure
+this library, users should read the ndn-cxx guide at
+[NDN-cxx]_.
+
+.. _nfd:
+
+3. Installing NFD
+=================
+
+3.1 Before installing NFD
+-------------------------
+
+An updated list of the packages and programs that need to be installed
+before NFD is provided at [NDNNFD]_. Before installing
+NFD it is necessary to verify that the following packages are installed:
+
+#. pcap library
+
+   ::
+
+       $ dnf list --installed libpcap-devel
+
+3.2 Downloading and installing NFD
+----------------------------------
+
+This software is downloaded and installed in a folder called *NFD*, which
+should be created at the directory defined at § `1 <#intro>`__. The
+following commands need to be run as a regular user:
+
+::
+
+      $ git clone --depth 1 https://github.com/named-data/NFD.git
+      $ cd NFD
+      $ ./waf configure
+
+If the previous command prints an error message saying that waf cannot
+find WebSocket, it is necessary to follow the instructions provided by
+this same output, which tells the user to run the following command:
+
+::
+
+      $ git submodule update --init
+
+After executing these instructions, complete the configuration by running
+``./waf configure`` again. Then complete the installation by means of the
+following commands:
+
+::
+
+      $ ./waf
+      $ sudo ./waf install
+
+3.3 Configuring NFD
+-------------------
+
+Create a configuration file by running the following command as root:
+
+::
+
+      $ cp /usr/local/etc/ndn/nfd.conf.sample /usr/local/etc/ndn/nfd.conf
+
+After the configuration file has been created, NFD's behavior may be
+changed by modifying this file. Once the configuration file has been
+created, it is recommended to start NFD by using the following command:
+
+::
+
+      $ nfd-start
+
+This command does not properly allow to employ the command window to
+enter new commands; however it displays the NFD logs. Therefore, it is
+recommended to open a new command window. This second window may be used
+to verify NDF's status and then stop NFD by using the following
+commands:
+
+::
+
+      $ nfd-status
+      $ nfd-stop
+
+.. _nlsr:
+
+4. Installing NLSR
+==================
+
+4.1 Installing PSync
+--------------------
+
+Before installing NLSR, it is also necessary to download and install
+PSync. PSync is a synchronization library which allows NLSR to synchronize LSAs
+similar to ChronoSync. More information about PSync may be found at [PSync]_.
+This library may be installed by running the following commands as a regular
+user and at the directory defined at § `1 <#intro>`__:
+
+::
+
+      $ git clone --depth 1 https://github.com/named-data/PSync.git
+      $ cd PSync
+      $ ./waf configure
+      $ ./waf
+      $ sudo ./waf install
+
+The following command needs to be used again to configure the libraries:
+
+::
+
+      $ sudo ldconfig -v | grep -i psync
+
+This command should display a line similar to the following:
+
+::
+
+         libPSync.so.0.1.0 -> libPSync.so.0.1.0
+
+4.2 [Optional] Installing ChronoSync
+------------------------------------
+
+By default NLSR no longer builds with ChronoSync support.
+Since ChronoSync is deprecated, only install it for testing purposes.
+
+Before installing NLSR, it is necessary to first download and install
+ChronoSync, which is a synchronization library which allows NLSR routers
+to synchronize Link State Advertisements (LSAs). More information about
+ChronoSync may be found at [Chronosync]_. This library may be
+installed by running the following commands as a regular user and at the
+directory defined at § `1 <#intro>`__:
+
+::
+
+      $ git clone --depth 1 https://github.com/named-data/ChronoSync.git
+      $ cd ChronoSync
+      $ ./waf configure
+      $ ./waf
+      $ sudo ./waf install
+
+The following command needs to be used again to configure the libraries:
+
+::
+
+      $ sudo ldconfig -v | grep -i chronosync
+
+This command should display a line similar to the following:
+
+::
+
+         libChronoSync.so.0.5.0 -> libChronoSync.so.0.5.0
+
+4.3 [Optional] Installing SVS
+-----------------------------
+
+NLSR can also use State Vector Sync as the underlying Sync protocol,
+using the ndn-svs library.
+
+This library may be installed by running the following commands as a
+regular user and at the directory defined at § `1 <#intro>`__:
+
+::
+
+      $ git clone --depth 1 https://github.com/named-data/ndn-svs.git
+      $ cd ndn-svs
+      $ ./waf configure
+      $ ./waf
+      $ sudo ./waf install
+
+The following command needs to be used again to configure the libraries:
+
+::
+
+      $ sudo ldconfig -v | grep ndn-svs
+
+This command should display a line similar to the following:
+
+::
+
+         libndn-svs.so.0.0.1 -> libndn-svs.so.0.0.1
+
+4.4 Downloading and installing NLSR
+-----------------------------------
+
+NLSR is downloaded and installed in a folder called *NLSR* which should
+be created at the directory defined at § `1 <#intro>`__. The following
+commands need to be run as a regular user:
+
+::
+
+      $ git clone --depth 1 https://github.com/named-data/NLSR.git
+      $ cd NLSR
+      $ ./waf configure
+      $ ./waf
+      $ sudo ./waf install
+
+If ChronoSync support is needed for testing, please configure NLSR with:
+
+::
+
+      $ ./waf configure --with-chronosync
+
+4.5 Configuring NLSR
+--------------------
+
+Create and configure the following directory by running the following
+commands as root:
+
+::
+
+      $ mkdir /var/lib/nlsr
+      $ chmod 777 /var/lib/nlsr
+
+.. _test:
+
+5. Configuring and Testing NLSR
+===============================
+
+To test NLSR, the first step is to configure the keys and certificates
+that implement a secure communication between the routers. Then it is
+necessary to verify that the computers in the test network are
+connected, that NFD is running and the faces between the computers are
+configured. Finally, the NLSR configuration file has to be edited before
+running NLSR. The following subsections are provided as a guide to
+define and configure a simple computer network between two computers:
+router1 and router2.
+
+.. _security:
+
+5.1 Setting up the security
+---------------------------
+
+Configuring security in an NDN network requires to generate, exchange
+and install, keys and certificates between the root, site, operator and
+router computers that form the network
+[NLSRsecconf]_, [NLSRdevguide]_, although in practice, it
+is possible to keep more than one of these entities in a single machine.
+The following example and *Figure 1* show how to configure security
+for a single router, called Router X. In this example, the root, site,
+operator and Router X are in different computers:
+
+.. figure:: security_comp.png
+   :alt: Security configuration example for Router X.
+   :width: 19cm
+   :align: center
+
+   Fig. 1. Security configuration example for Router X.
+
+
+#. At the root server, generate the root key:
+
+   ::
+
+       $ ndnsec-key-gen /ndn/ > root.key
+
+#. Generate the certificate for the root key at the root server:
+
+   ::
+
+       $ ndnsec-cert-dump -i /ndn/ > root.cert
+
+#. Install the root certificate at the root server:
+
+   ::
+
+       $ ndnsec-cert-install -f root.cert
+
+#. At the site server, generate the site key:
+
+   ::
+
+       $ ndnsec-key-gen /ndn/edu/uaslp > site.key
+
+#. Copy the site key to the root server and generate the certificate for
+   the site server:
+
+   ::
+
+       $ ndnsec-cert-gen -s /ndn/ site.key > site.cert
+
+#. Copy the site certificate to the site server and install it:
+
+   ::
+
+       $ ndnsec-cert-install -f site.cert
+
+#. At the operator server, generate the operator key:
+
+   ::
+
+       $ ndnsec-key-gen /ndn/edu/uaslp/%C1.Operator/op > op.key
+
+#. Copy the operator key to the site server and generate the certificate
+   for the operator server:
+
+   ::
+
+       $ ndnsec-cert-gen -s /ndn/edu/uaslp op.key > op.cert
+
+#. Copy the operator certificate to the operator server and install it:
+
+   ::
+
+       $ ndnsec-cert-install -f op.cert
+
+#. At the router, generate the router key:
+
+   ::
+
+       $ ndnsec-key-gen /ndn/edu/uaslp/%C1.Router/routerX > routerX.key
+
+#. Copy the router key to the operator server and generate the
+   certificate for the router:
+
+   ::
+
+       $ ndnsec-cert-gen -s /ndn/edu/uaslp/%C1.Operator/op routerX.key >
+         routerX.cert
+
+#. Copy the router certificate to the router and install it:
+
+   ::
+
+       $ ndnsec-cert-install -f routerX.cert
+
+In the previous steps, the *%C1.Router* and *%C1.Operator* labels are
+NDN keywords and should not be changed. These labels will be also used
+by the configuration file (§ `5.4 <#configfile>`__)
+
+The following command may be used to verify that the certificates have
+been installed in a computer:
+
+::
+
+      $ ndnsec-list
+
+This guide recommends that one machine functions as the root, site,
+operator and router1, while a different computer only functions as
+router2. *Figure 2* shows this
+configuration. For router1, the twelve steps described before need to be
+executed except for exchanging files between computers. For the router2,
+only steps 10 to 12 are needed to generate this router's certificate.
+
+Additionally, the following command may be used to print a list and a
+brief description of all the ``ndnsec`` commands:
+
+::
+
+      $ man ndnsec
+
+
+.. figure:: netwk1.png
+   :alt: Example network.
+   :width: 19cm
+   :align: center
+
+   Fig. 2. Example network.
+
+
+5.2 Configuring the network
+---------------------------
+
+The first step is to configure the physical network. If two computers
+are going to get connected using a single Ethernet cable, it is
+necessary to verify that this cable is a crossover. The other option is
+to employ a switch between two computers that are then connected using
+two regular Ethernet cables.
+
+After the physical network has been assembled, it is necessary to
+configure the network addresses and cards for all the computers in the
+network. It is important to remember that computers that are connected
+to each other should use the same subnetwork address. It is possible to
+verify the network configuration in a Linux computer by means of the
+``ip addr`` command.
+
+Once the physical network and network cards have been configured, it is
+necessary to verify that the computers can communicate with each other.
+The simplest way to do this is by using the ``ping`` command:
+
+::
+
+      $ ping <remote-ip-address>
+
+5.3 Starting and configuring NFD
+--------------------------------
+
+To start and configure NFD it is necessary to open two terminal windows.
+The first one will be used to start NFD by means of the ``nfd-start``
+command. This terminal will also display the logs that NFD generates. By
+default, NFD only generates informational logs (INFO). However, it is
+possible to obtain different levels of verbosity for these logs. These
+levels can be set before NFD starts by editing the
+*/usr/local/etc/ndn/nfd.conf* file. Open this file using a regular text
+editor, read the information provided about logging and then modify the
+*default-level* variable at the *log* section according to the
+instructions provided in the file. Additional information about NFD
+configuration may be found at [NDNNFDusage]_.
+
+The second terminal will be used to monitor the NFD status:
+
+::
+
+      $ nfd-status
+
+Employ the following command to configure each face that a computer uses
+to connect to a neighboring computer:
+
+::
+
+      $ nfdc face create udp4://<remote-ip-address>
+
+The face id may be displayed by running:
+
+::
+
+      $ nfdc face list
+
+The status of the face may be verified by using the following command:
+
+::
+
+      $ nfdc face show id <face-id>
+
+After finishing NLSR testing, it is necessary to destroy the face before
+stopping NFD. This operation is described at § `5.6 <#turn_off>`__. For
+the two computer network provided as an example (*Figure 2*), it is necessary that both
+machines run NFD and that each one configures a face that connects to
+the other machine.
+
+.. _configfile:
+
+5.4 Setting up the configuration file
+-------------------------------------
+
+Instructions on how to use the configuration file are already provided
+at the NLSR's Router Configuration page [NLSRrtrconf]_.
+Read the information in this page to understand NLSR router
+configuration. The following text describes the instructions that have
+been modified at the default nlsr.conf file for router1:
+
+::
+
+    ; AT general SECTION:
+    {
+      network /ndn/                    ; name of the network
+      site /edu/uaslp                  ; name of the site
+      router /%C1.Router/router1       ; name of the router: router1
+    }
+
+    ;AT neighbors SECTION:
+    neighbors
+    {
+      neighbor
+      {
+        name /ndn/edu/uaslp/%C1.Router/router2   ; Neighbor router: router2
+        face-uri  udp://140.220.80.124           ; face to the neighbor
+        link-cost 30                             ; cost of the link
+      }
+    }
+
+    ; AT advertising SECTION:
+    advertising
+    {
+      prefix /ndn/edu/uaslp/office/bldg1         ; Advertising destinations
+      prefix /ndn/edu/uaslp/office/bldg2         ; for router1
+    }
+
+    ; AT security SECTION:
+    security
+    {
+      validator
+      {
+        ...
+        trust-anchor
+        {
+          type file
+          file-name "root.cert"        ; root certificate file
+        }
+      }
+
+      prefix-update-validator
+      {
+        ...
+        trust-anchor
+        {
+          type file
+          file-name "site.cert"        ; site certificate file
+        }
+      }
+
+      cert-to-publish "root.cert"      ; root certificate file
+
+      cert-to-publish "site.cert"      ; site certificate file
+
+      cert-to-publish "op.cert"        ; operator certificate file
+
+      cert-to-publish "router1.cert"   ; router1 certificate file
+    }
+
+The following text shows the modified instructions for router2:
+
+::
+
+    ; AT general SECTION:
+    {
+      network /ndn/                    ; name of the network
+      site /edu/uaslp                  ; name of the site
+      router /%C1.Router/router2       ; name of the router: router2
+    }
+
+    ;AT neighbors SECTION:
+    neighbors
+    {
+      neighbor
+      {
+        name /ndn/edu/uaslp/%C1.Router/router1   ; Neighbor router: router1
+        face-uri  udp://140.220.80.121           ; face to the neighbor
+        link-cost 30                             ; cost of the link
+      }
+    }
+
+    ; AT advertising SECTION:
+    advertising
+    {
+      prefix /ndn/edu/uaslp/labs/networks        ; Advertising destinations
+      prefix /ndn/edu/uaslp/labs/hardware        ; for router2
+    }
+
+    ; AT security SECTION:
+    security
+    {
+      validator
+      {
+        ...
+        trust-anchor
+        {
+          type file
+          file-name "root.cert"        ; root certificate file
+        }                              ; this file needs to be copied to
+      }                                ; router2
+
+      prefix-update-validator
+      {
+        ...
+        trust-anchor
+        {
+          type file
+          file-name "site.cert"        ; site certificate file
+        }                              ; this file needs to be copied to
+      }                                ; router2
+
+      ...
+      cert-to-publish "router2.cert"   ; router2 certificate file
+    }
+
+Notice that files *root.cert* and *site.cert*, which were generated at
+router1, need to be copied to router2. Also notice that the *%C1.Router*
+and *%C1.Operator* keywords employed at § `5.1 <#security>`__ are also
+referenced by these configuration files.
+
+.. _starting_nlsr:
+
+5.5 Starting NLSR
+-----------------
+
+It is recommended to open a third command terminal and run NLSR in this
+window. After the NLSR configuration file has been edited and saved as
+*nlsr.conf*, it is possible to start NLSR by running either of the
+following two commands:
+
+::
+
+      $ nlsr
+      $ nlsr -f <configuration-file>
+
+However, to verify what is NLSR doing, it becomes necessary to employ
+NLSR's logging facility [NLSRstarting]_. A brief
+description on how to use NDN's logging facility may be displayed by
+entering the ``man ndn-log`` command. This guide recommends using one
+of the following two instructions to start NLSR:
+
+::
+
+      $ export NDN_LOG=nlsr.*=TRACE && nlsr
+      $ export NDN_LOG=nlsr.*=TRACE && nlsr -f <configuration-file>
+
+The second terminal window may be used to run ``nfd-status`` again and
+it should be possible to verify that the status has changed, specially
+at the FIB and RIB sections of the generated report.
+
+.. _turn_off:
+
+5.6 Turning everything off
+--------------------------
+
+In order to stop NLSR and NFD, the following sequence of events is
+recommended:
+
+#. Stop NLSR by pressing the Ctrl+C keys at the third terminal window.
+
+#. Destroy the face to the remote computers using either of the
+   following two commands at the second terminal window:
+
+   ::
+
+       $ nfdc face destroy <face-id>
+       $ nfdc face destroy udp4://<remote-ip-address>
+
+#. Stop NFD by entering the following command at the second terminal
+   window:
+
+   ::
+
+       $ nfd-stop
+
+#. The crossover Ethernet cable may be unplugged and the computers'
+   network configuration restored to its original settings.
+
+5.7 Where to go from here
+-------------------------
+
+Users interested in building and configuring larger networks may want to
+take a look at the NDN Ansible repository
+[NDNAnsible]_. This repository uses Ansible, which is a
+configuration management tool, to manage the official NDN testbed

+
+**NLSR** is a routing protocol for Named Data Networking (NDN) that populates the Routing
+Information Base (RIB) of an NDN router, such as `NFD`_. NLSR continues to evolve alongside
+the core `NDN protocol`_.
+
+The main design goal of NLSR is to provide a routing protocol to populate NDN's FIB. NLSR
+calculates the routing table using link-state or hyperbolic routing and produces multiple
+faces for each reachable name prefix in a single authoritative domain. NLSR will continue
+to evolve over time to include neighbor discovery and to become a full fledged
+inter-domain routing protocol for NDN.  The protocol design is presented in full detail in
+the `NLSR Paper`_.

+nlsrc
+=====
+
+Usage
+-----
+
+::
+
+    nlsrc [-h | -V]
+    nlsrc [-R <router prefix> [-c <nlsr.conf path> | -k]] COMMAND [<Command Options>]
+
+
+Description
+-----------
+
+``nlsrc`` is a tool to retrieve link-state database (LSDB) status information from NLSR and
+announce/withdraw Name prefixes advertised by NLSR.
+
+Options
+-------
+
+``-h``
+  Print usage information
+
+``-V``
+  Show NLSRC version information
+
+``-R <router prefix>``
+  Target a remote NLSR instance.
+  The default is the local NLSR instance ``/localhost``.
+
+``-c <nlsr.conf path>``
+  Verify remote status information with the trust schema loaded from ``security.validator`` section of specified nlsr.conf config file.
+  The default is loading from ``/etc/ndn/nlsr.conf``.
+
+``-k``
+  Insecure: do not verify signature on status information retrieved from remote router.
+
+``COMMAND``
+
+  ``lsdb``
+    Retrieve LSDB status information
+
+  ``routing``
+    Retrieve routing table status information
+
+  ``status``
+    Retrieve LSDB status and routing table status information
+
+  ``advertise``
+    Add a Name prefix to be advertised by NLSR
+
+    ``advertise <name>``
+
+      ``name``
+        The Name prefix to be advertised
+
+    ``advertise <name> save``
+
+      ``save``
+        Advertise a prefix and also save it to the nlsr.conf file residing in the state-dir for the next start of NLSR that operator may copy and use for the next start of NLSR
+
+  ``withdraw``
+    Remove a Name prefix advertised through NLSR
+
+    ``withdraw <name>``
+
+      ``name``
+        The Name prefix to be withdrawn
+
+    ``withdraw <name> delete``
+
+      ``delete``
+        Withdraw a prefix and also delete it from the nlsr.conf file residing in the state-dir
+
+Notes
+-----
+
+When security is enabled, NLSR will not be allowed to successfully
+advertise/withdraw names without first setting a default identity of operator.
+If default identity is not set as operator, the user will be presented with the
+error message: "Name prefix update error (code: 403)". To remedy this
+issue, use the command ``ndnsec set-default``. Example::
+
+  ndnsec set-default /ndn/a-site/%C1.Operator/op
+
+Exit Status
+-----------
+
+nlsrc exits with one of the following values::
+
+  0     nlsrc exited successfully
+  1     generic error
+  2     bad command line

+NLSR version 0.1.0 (initial release)
+++++++++++++++++++++++++++++++++++++
+
+Release date: August 25, 2014
+
+The main design goal of NLSR is to provide a routing protocol to populate `NFD's
+<https://github.com/named-data/NFD>`__ RIB.  NLSR calculates the routing table using
+link-state or hyperbolic routing and produces multiple faces for each reachable name
+prefix in a single authoritative domain.
+
+Included features
+^^^^^^^^^^^^^^^^^
+
+- Advertise availability of content through the configured router
+
+- Use `ChronoSync <https://github.com/named-data/ChronoSync>`__ to synchronize routers' LSA sequence numbers and Interest/Data to retrieve LSAs
+
+- Produce a list of ranked forwarding options for each name prefix to facilitate NDN's adaptive forwarding strategies
+
+- Configure maximum number of faces per prefix in NFD's RIB
+
+- Set up NFD tunnels to neighbors automatically and maintain the tunnels to neighbors
+
+- Provide two routing protocols:
+
+  + Link State routing: calculate route cost based on link costs
+  + Hyperbolic routing: calculate route cost based on hyperbolic coordinates
+
+- Use a hierarchical trust model for routing within a single administrative domain
+
+- Keep NFD's RIB updated on failure and recovery
