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.

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains TERMS AND CONDITIONS
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not 0. Definitions.
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's "This License" refers to version 3 of the GNU General Public License.
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and "Copyright" also means copyright-like laws that apply to other kinds of

2. You may modify your copy or copies of the Program or any portion "The Program" refers to any copyrightable work licensed under this
of it, thus forming a work based on the Program, and copy and License. Each licensee is addressed as "you". "Licensees" and

a) You must cause the modified files to carry prominent notices To "modify" a work means to copy from or adapt all or part of the work
stating that you changed the files and the date of any change. 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.
b) You must cause any work that you distribute or publish, that in A "covered work" means either the unmodified Program or a work based

c) If the modified program normally reads commands interactively To "propagate" a work means to do anything with it that, without

interactive use in the most ordinary way, to print or display an infringement under applicable copyright law, except executing it on a
announcement including an appropriate copyright notice and a computer or modifying a private copy. Propagation includes copying,
notice that there is no warranty (or else, saying that you provide distribution (with or without modification), making available to the
a warranty) and that users may redistribute the program under public, and in some countries other activities as well.
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest To "convey" a work means any kind of propagation that enables other
your rights to work written entirely by you; rather, the intent is to parties to make or receive copies. Mere interaction with a user through

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.
3. You may copy and distribute the Program (or a work based on it, 1. Source Code.

Sections 1 and 2 above provided that you also do one of the following:

"Major Component", in this context, means a major essential component

distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.

distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the 2. Basic Permissions.

these terms and conditions. You may not impose any further copyright on the Program, and are irrevocable provided the stated
restrictions on the recipients' exercise of the rights granted herein. conditions are met. This License explicitly affirms your unlimited
You are not responsible for enforcing compliance by third parties to 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. this License.
7. If, as a consequence of a court judgment or allegation of patent Each contributor grants you a non-exclusive, worldwide, royalty-free
infringement or for any other reason (not limited to patent issues), patent license under the contributor's essential patent claims, to
conditions are imposed on you (whether by court order, agreement or 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

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.

a good idea to add these lines to `/etc/modules.conf':

@cindex ethertap
For kernels up to 2.4.0, you need a kernel that supports the ethertap device.
Most distributions come with kernels that already support this.
If not, here are the options you have to turn on when configuring a new kernel:
@example
Code maturity level options
[*] Prompt for development and/or incomplete code/drivers
Networking options
[*] Kernel/User netlink socket
<M> Netlink device emulation
Network device support
<M> Ethertap network tap
@end example
If you want to run more than one instance of tinc or other programs that use
the ethertap, you have to compile the ethertap driver as a module, otherwise
you can also choose to compile it directly into the kernel.
If you decide to build any of these as dynamic kernel modules, it's a good idea
to add these lines to @file{/etc/modules.conf}:
@example
alias char-major-36 netlink_dev
alias tap0 ethertap
options tap0 -o tap0 unit=0
alias tap1 ethertap
options tap1 -o tap1 unit=1
...
alias tap@emph{N} ethertap
options tap@emph{N} -o tap@emph{N} unit=@emph{N}
@end example
Add as much alias/options lines as necessary.

First, you'll need the special device file(s) that form the interface Most operating systems nowadays come with the necessary device files by default,
between the kernel and the daemon. or they have a mechanism to create them on demand.
The permissions for these files have to be such that only the super user If you use Linux and do not have udev installed,
may read/write to this file. You'd want this, because otherwise you may need to create the following device file if it does not exist:
eavesdropping would become a bit too easy. This does, however, imply
that you'd have to run tincd as root.
If you use Linux and have a kernel version prior to 2.4.0, you have to make the
ethertap devices:
@example @example
mknod -m 600 /dev/tap0 c 36 16 mknod -m 600 /dev/net/tun c 10 200
mknod -m 600 /dev/tap1 c 36 17
...
mknod -m 600 /dev/tap@emph{N} c 36 @emph{N+16}
@end example @end example
There is a maximum of 16 ethertap devices.
If you use the universal tun/tap driver, you have to create the
following device file (unless it already exist):
@example
mknod -m 600 /dev/tun c 10 200
@end example
If you use Linux, and you run the new 2.4 kernel using the devfs filesystem,
then the tun/tap device will probably be automatically generated as
@file{/dev/net/tun}.
Unlike the ethertap device, you do not need multiple device files if
you are planning to run multiple tinc daemons.

encryption to create a secure private network between hosts on the
Internet.
</p>
<p>Because the tunnel appears to the IP level network code as a normal
network device, there is no need to adapt any existing software.
The encrypted tunnels allows VPN sites to share information with each other
over the Internet without exposing any information to others.
</p>
<p>This document is the manual for tinc. Included are chapters on how to
configure your computer to use tinc, as well as the configuration
process of tinc itself.

<h2 class="section"> 1.1 Virtual Private Networks </h2>
<a name="IDX1"></a>
<p>A Virtual Private Network or VPN is a network that can only be accessed
by a few elected computers that participate. This goal is achievable in
more than just one way.
</p>
<a name="IDX2"></a>
<p>Private networks can consist of a single stand-alone Ethernet LAN. Or
even two computers hooked up using a null-modem cable. In these cases,
it is
obvious that the network is <em>private</em>, no one can access it from the
outside. But if your computers are linked to the Internet, the network
is not private anymore, unless one uses firewalls to block all private
traffic. But then, there is no way to send private data to trusted
computers on the other end of the Internet.
</p>
<p>This problem can be solved by using <em>virtual</em> networks. Virtual
networks can live on top of other networks, but they use encapsulation to
keep using their private address space so they do not interfere with
the Internet. Mostly, virtual networks appear like a singe LAN, even though
they can span the entire world. But virtual networks can't be secured
by using firewalls, because the traffic that flows through it has to go
through the Internet, where other people can look at it.
</p>
<p>As is the case with either type of VPN, anybody could eavesdrop. Or
worse, alter data. Hence it's probably advisable to encrypt the data
that flows over the network.
</p>
<p>When one introduces encryption, we can form a true VPN. Other people may
see encrypted traffic, but if they don't know how to decipher it (they
need to know the key for that), they cannot read the information that flows
through the VPN. This is what tinc was made for.

<h2 class="section"> 1.2 tinc </h2>
<a name="IDX3"></a>
<p>I really don't quite remember what got us started, but it must have been
Guus' idea. He wrote a simple implementation (about 50 lines of C) that
used the ethertap device that Linux knows of since somewhere
about kernel 2.1.60. It didn't work immediately and he improved it a
bit. At this stage, the project was still simply called &quot;vpnd&quot;.
</p>
<p>Since then, a lot has changed&mdash;to say the least.
</p>
<a name="IDX4"></a>
<p>Tinc now supports encryption, it consists of a single daemon (tincd) for
both the receiving and sending end, it has become largely
runtime-configurable&mdash;in short, it has become a full-fledged
professional package.
</p>
<a name="IDX5"></a>
<p>Tinc also allows more than two sites to connect to eachother and form a single VPN.
Traditionally VPNs are created by making tunnels, which only have two endpoints.
Larger VPNs with more sites are created by adding more tunnels.
Tinc takes another approach: only endpoints are specified,
the software itself will take care of creating the tunnels.
This allows for easier configuration and improved scalability.
</p>
<p>A lot can&mdash;and will be&mdash;changed. We have a number of things that we would like to
see in the future releases of tinc. Not everything will be available in
the near future. Our first objective is to make tinc work perfectly as
it stands, and then add more advanced features.
</p>
<p>Meanwhile, we're always open-minded towards new ideas. And we're
available too.

<h2 class="section"> 1.3 Supported platforms </h2>
<a name="IDX6"></a>
<p>Tinc has been verified to work under Linux, FreeBSD, OpenBSD, NetBSD, MacOS/X (Darwin), Solaris, and Windows (both natively and in a Cygwin environment),
with various hardware architectures. These are some of the platforms
that are supported by the universal tun/tap device driver or other virtual network device drivers.
Without such a driver, tinc will most
likely compile and run, but it will not be able to send or receive data
packets.
</p>

<p>For tinc to work, you need a kernel that supports the Universal tun/tap device.
Most distributions come with kernels that already support this.
Here are the options you have to turn on when configuring a new kernel:

<p>It's not necessary to compile this driver as a module, even if you are going to
run more than one instance of tinc.

<p>For all cryptography-related functions, tinc uses the functions provided
by the OpenSSL library.

<p>If this library is not installed, you wil get an error when configuring
tinc for build. Support for running tinc without having OpenSSL
installed <em>may</em> be added in the future.

<p>You can use your operating system's package manager to install this if
available. Make sure you install the development AND runtime versions
of this package.

<p>If you have to install OpenSSL manually, you can get the source code
from <a href="http://www.openssl.org/">http://www.openssl.org/</a>. Instructions on how to configure,
build and install this package are included within the package. Please
make sure you build development and runtime libraries (which is the
default).

<p>If you installed the OpenSSL libraries from source, it may be necessary
to let configure know where they are, by passing configure one of the

<p>The complete source code of tinc is covered by the GNU GPL version 2.
Since the license under which OpenSSL is distributed is not directly
compatible with the terms of the GNU GPL
<a href="http://www.openssl.org/support/faq.html#LEGAL2">http://www.openssl.org/support/faq.html#LEGAL2</a>, we
include an exemption to the GPL (see also the file COPYING.README) to allow
everyone to create a statically or dynamically linked executable:

<blockquote><p>This program is released under the GPL with the additional exemption
that compiling, linking, and/or using OpenSSL is allowed. You may
provide binary packages linked to the OpenSSL libraries, provided that
all other requirements of the GPL are met.

<p>Since the LZO library used by tinc is also covered by the GPL,
we also present the following exemption:

<h1 class="chapter"> 3. Installation </h1>
<p>If you use Debian, you may want to install one of the
precompiled packages for your system. These packages are equipped with
system startup scripts and sample configurations.
</p>
<p>If you cannot use one of the precompiled packages, or you want to compile tinc
for yourself, you can use the source. The source is distributed under
the GNU General Public License (GPL). Download the source from the
<a href="http://www.tinc-vpn.org/download">download page</a>, which has
the checksums of these files listed; you may wish to check these with
md5sum before continuing.
</p>
<p>Tinc comes in a convenient autoconf/automake package, which you can just
treat the same as any other package. Which is just untar it, type
`./configure' and then `make'.
More detailed instructions are in the file &lsquo;<tt>INSTALL</tt>&rsquo;, which is
included in the source distribution.

<p>In order to build tinc on Darwin, you need to install the MacOS/X Developer Tools
from <a href="http://developer.apple.com/tools/macosxtools.html">http://developer.apple.com/tools/macosxtools.html</a> and
a recent version of Fink from <a href="http://fink.sourceforge.net/">http://fink.sourceforge.net/</a>.
</p>
<p>After installation use fink to download and install the following packages:
autoconf25, automake, dlcompat, m4, openssl, zlib and lzo.

<p>If Cygwin hasn't already been installed, install it directly from
<a href="http://www.cygwin.com/">http://www.cygwin.com/</a>.
</p>
<p>When tinc is compiled in a Cygwin environment, it can only be run in this environment,
but all programs, including those started outside the Cygwin environment, will be able to use the VPN.
It will also support all features.

<h2 class="section"> 5.4 Solving problems </h2>
<p>If tinc starts without problems, but if the VPN doesn't work, you will have to find the cause of the problem.
The first thing to do is to start tinc with a high debug level in the foreground,
so you can directly see everything tinc logs:
</p>
<table><tr><td>&nbsp;</td><td><pre class="example">tincd -n <var>netname</var> -d5 -D
</pre></td></tr></table>
<p>If tinc does not log any error messages, then you might want to check the following things:
</p>
<ul class="toc">
<li> &lsquo;<tt>tinc-up</tt>&rsquo; script
Does this script contain the right commands?
Normally you must give the interface the address of this host on the VPN, and the netmask must be big enough so that the entire VPN is covered.
</li><li> Subnet
Does the Subnet (or Subnets) in the host configuration file of this host match the portion of the VPN that belongs to this host?
</li><li> Firewalls and NATs
Do you have a firewall or a NAT device (a masquerading firewall or perhaps an ADSL router that performs masquerading)?
If so, check that it allows TCP and UDP traffic on port 655.
If it masquerades and the host running tinc is behind it, make sure that it forwards TCP and UDP traffic to port 655 to the host running tinc.
You can add &lsquo;<samp>TCPOnly = yes</samp>&rsquo; to your host config file to force tinc to only use a single TCP connection,
this works through most firewalls and NATs.

<h3 class="subsection"> 6.1.1 The UDP tunnel </h3>
<a name="IDX68"></a>
<p>The data itself is read from a character device file, the so-called
<em>virtual network device</em>. This device is associated with a network
interface. Any data sent to this interface can be read from the device,
and any data written to the device gets sent from the interface.
There are two possible types of virtual network devices:
`tun' style, which are point-to-point devices which can only handle IPv4 and/or IPv6 packets,
and `tap' style, which are Ethernet devices and handle complete Ethernet frames.
</p>
<p>So when tinc reads an Ethernet frame from the device, it determines its
type. When tinc is in it's default routing mode, it can handle IPv4 and IPv6
packets. Depending on the Subnet lines, it will send the packets off to their destination IP address.
In the `switch' and `hub' mode, tinc will use broadcasts and MAC address discovery
to deduce the destination of the packets.
Since the latter modes only depend on the link layer information,
any protocol that runs over Ethernet is supported (for instance IPX and Appletalk).
However, only `tap' style devices provide this information.
</p>
<p>After the destination has been determined,
the packet will be compressed (optionally),
a sequence number will be added to the packet,
the packet will then be encrypted
and a message authentication code will be appended.
</p>
<a name="IDX69"></a>
<a name="IDX70"></a>
<p>When that is done, time has come to actually transport the
packet to the destination computer. We do this by sending the packet
over an UDP connection to the destination host. This is called
<em>encapsulating</em>, the VPN packet (though now encrypted) is
encapsulated in another IP datagram.
</p>
<p>When the destination receives this packet, the same thing happens, only
in reverse. So it checks the message authentication code, decrypts the contents of the UDP datagram,
checks the sequence number
and writes the decrypted information to its own virtual network device.
</p>
<p>If the virtual network device is a `tun' device (a point-to-point tunnel),
there is no problem for the kernel to accept a packet.
However, if it is a `tap' device (this is the only available type on FreeBSD),
the destination MAC address must match that of the virtual network interface.
If tinc is in it's default routing mode, ARP does not work, so the correct destination MAC
can not be known by the sending host.
Tinc solves this by letting the receiving end detect the MAC address of its own virtual network interface
and overwriting the destination MAC address of the received packet.
</p>
<p>In switch or hub modes ARP does work so the sender already knows the correct destination MAC address.
In those modes every interface should have a unique MAC address, so make sure they are not the same.
Because switch and hub modes rely on MAC addresses to function correctly,
these modes cannot be used on the following operating systems which don't have a `tap' style virtual network device:
OpenBSD, NetBSD, Darwin and Solaris.

<h3 class="subsection"> 6.1.2 The meta-connection </h3>
<p>Having only a UDP connection available is not enough. Though suitable
for transmitting data, we want to be able to reliably send other
information, such as routing and session key information to somebody.
</p>
<a name="IDX71"></a>
<p>TCP is a better alternative, because it already contains protection
against information being lost, unlike UDP.
</p>
<p>So we establish two connections. One for the encrypted VPN data, and one
for other information, the meta-data. Hence, we call the second
connection the meta-connection. We can now be sure that the
meta-information doesn't get lost on the way to another computer.
</p>
<a name="IDX72"></a>
<a name="IDX73"></a>
<p>Like with any communication, we must have a protocol, so that everybody
knows what everything stands for, and how she should react. Because we
have two connections, we also have two protocols. The protocol used for
the UDP data is the &ldquo;data-protocol,&rdquo; the other one is the
&ldquo;meta-protocol.&rdquo;
</p>
<p>The reason we don't use TCP for both protocols is that UDP is much
better for encapsulation, even while it is less reliable. The real
problem is that when TCP would be used to encapsulate a TCP stream
that's on the private network, for every packet sent there would be
three ACKs sent instead of just one. Furthermore, if there would be
a timeout, both TCP streams would sense the timeout, and both would
start re-sending packets.

<h2 class="section"> 6.2 The meta-protocol </h2>
<p>The meta protocol is used to tie all tinc daemons together, and
exchange information about which tinc daemon serves which virtual
subnet.
</p>
<p>The meta protocol consists of requests that can be sent to the other
side. Each request has a unique number and several parameters. All
requests are represented in the standard ASCII character set. It is
possible to use tools such as telnet or netcat to connect to a tinc
daemon started with the &ndash;bypass-security option
and to read and write requests by hand, provided that one
understands the numeric codes sent.
</p>
<p>The authentication scheme is described in <a href="#SEC62">Authentication protocol</a>. After a
successful authentication, the server and the client will exchange all the
information about other tinc daemons and subnets they know of, so that both
sides (and all the other tinc daemons behind them) have their information
synchronised.

<p>The keys used to encrypt VPN packets are not sent out directly. This is
because it would generate a lot of traffic on VPNs with many daemons, and
chances are that not every tinc daemon will ever send a packet to every
other daemon. Instead, if a daemon needs a key it sends a request for it
via the meta connection of the nearest hop in the direction of the
destination.

<p>There is also a mechanism to check if hosts are still alive. Since network
failures or a crash can cause a daemon to be killed without properly
shutting down the TCP connection, this is necessary to keep an up to date
connection list. PINGs are sent at regular intervals, except when there
is also some other traffic. A little bit of salt (random data) is added
with each PING and PONG message, to make sure that long sequences of PING/PONG
messages without any other traffic won't result in known plaintext.
</p>
<p>This basically covers what is sent over the meta connection by tinc.

<p>Tinc got its name from &ldquo;TINC,&rdquo; short for <em>There Is No Cabal</em>; the
alleged Cabal was/is an organisation that was said to keep an eye on the
entire Internet. As this is exactly what you <em>don't</em> want, we named
the tinc project after TINC.
</p>
<p>But in order to be &ldquo;immune&rdquo; to eavesdropping, you'll have to encrypt
your data. Because tinc is a <em>Secure</em> VPN (SVPN) daemon, it does
exactly that: encrypt.
Tinc by default uses blowfish encryption with 128 bit keys in CBC mode, 32 bit
sequence numbers and 4 byte long message authentication codes to make sure
eavesdroppers cannot get and cannot change any information at all from the
packets they can intercept. The encryption algorithm and message authentication
algorithm can be changed in the configuration. The length of the message
authentication codes is also adjustable. The length of the key for the
encryption algorithm is always the default length used by OpenSSL.

<h3 class="subsection"> 6.3.1 Authentication protocol </h3>
<a name="IDX83"></a>
<p>A new scheme for authentication in tinc has been devised, which offers some
improvements over the protocol used in 1.0pre2 and 1.0pre3. Explanation is
below.

--------------------------------------------------------------------------
</pre></td></tr></table>
<p>This new scheme has several improvements, both in efficiency and security.
</p>
<p>First of all, the server sends exactly the same kind of messages over the wire
as the client. The previous versions of tinc first authenticated the client,
and then the server. This scheme even allows both sides to send their messages
simultaneously, there is no need to wait for the other to send something first.
This means that any calculations that need to be done upon sending or receiving
a message can also be done in parallel. This is especially important when doing
RSA encryption/decryption. Given that these calculations are the main part of
the CPU time spent for the authentication, speed is improved by a factor 2.
</p>
<p>Second, only one RSA encrypted message is sent instead of two. This reduces the
amount of information attackers can see (and thus use for a cryptographic
attack). It also improves speed by a factor two, making the total speedup a
factor 4.
</p>
<p>Third, and most important:
The symmetric cipher keys are exchanged first, the challenge is done
afterwards. In the previous authentication scheme, because a man-in-the-middle
could pass the challenge/chal_reply phase (by just copying the messages between
the two real tinc daemons), but no information was exchanged that was really
needed to read the rest of the messages, the challenge/chal_reply phase was of
no real use. The man-in-the-middle was only stopped by the fact that only after
the ACK messages were encrypted with the symmetric cipher. Potentially, it
could even send it's own symmetric key to the server (if it knew the server's
public key) and read some of the metadata the server would send it (it was
impossible for the mitm to read actual network packets though). The new scheme
however prevents this.
</p>
<p>This new scheme makes sure that first of all, symmetric keys are exchanged. The
rest of the messages are then encrypted with the symmetric cipher. Then, each
side can only read received messages if they have their private key. The
challenge is there to let the other side know that the private key is really
known, because a challenge reply can only be sent back if the challenge is
decrypted correctly, and that can only be done with knowledge of the private
key.
</p>
<p>Fourth: the first thing that is sent via the symmetric cipher encrypted
connection is a totally random string, so that there is no known plaintext (for
an attacker) in the beginning of the encrypted stream.

<h3 class="subsection"> 6.3.2 Encryption of network packets </h3>
<a name="IDX88"></a>
<p>A data packet can only be sent if the encryption key is known to both
parties, and the connection is activated. If the encryption key is not
known, a request is sent to the destination using the meta connection
to retrieve it. The packet is stored in a queue while waiting for the
key to arrive.
</p>
<p>The UDP packet containing the network packet from the VPN has the following layout:
</p>
<table><tr><td>&nbsp;</td><td><pre class="example">... | IP header | UDP header | seqno | VPN packet | MAC | UDP trailer
\___________________/\_____/
| |
V +---&gt; digest algorithm
Encrypted with symmetric cipher
</pre></td></tr></table>
<p>So, the entire VPN packet is encrypted using a symmetric cipher, including a 32 bits
sequence number that is added in front of the actual VPN packet, to act as a unique
IV for each packet and to prevent replay attacks. A message authentication code
is added to the UDP packet to prevent alteration of packets. By default the
first 4 bytes of the digest are used for this, but this can be changed using
the MACLength configuration variable.

<h3 class="subsection"> 6.3.3 Security issues </h3>
<p>In August 2000, we discovered the existence of a security hole in all versions
of tinc up to and including 1.0pre2. This had to do with the way we exchanged
keys. Since then, we have been working on a new authentication scheme to make
tinc as secure as possible. The current version uses the OpenSSL library and
uses strong authentication with RSA keys.
</p>
<p>On the 29th of December 2001, Jerome Etienne posted a security analysis of tinc
1.0pre4. Due to a lack of sequence numbers and a message authentication code
for each packet, an attacker could possibly disrupt certain network services or
launch a denial of service attack by replaying intercepted packets. The current
version adds sequence numbers and message authentication codes to prevent such
attacks.
</p>
<p>On the 15th of September 2003, Peter Gutmann posted a security analysis of tinc
1.0.1. He argues that the 32 bit sequence number used by tinc is not a good IV,
that tinc's default length of 4 bytes for the MAC is too short, and he doesn't
like tinc's use of RSA during authentication. We do not know of a security hole
in this version of tinc, but tinc's security is not as strong as TLS or IPsec.
We will address these issues in tinc 2.0.
</p>
<p>Cryptography is a hard thing to get right. We cannot make any
guarantees. Time, review and feedback are the only things that can
prove the security of any cryptographic product. If you wish to review
tinc or give us feedback, you are stronly encouraged to do so.
