-ZeroTier - A Planetary Ethernet Switch
+ZeroTier - Global Area Networking
 ======
 
-ZeroTier is an enterprise Ethernet switch for planet Earth.
+ZeroTier is a smart programmable Ethernet switch for planet Earth. It allows networked devices and applications to be managed as if the entire world is one data center or cloud region.
 
-It erases the LAN/WAN distinction and makes VPNs, tunnels, proxies, and other kludges arising from the inflexible nature of physical networks obsolete. Everything is encrypted end-to-end and traffic takes the most direct (peer to peer) path available.
+It replaces the physical LAN/WAN boundary with a virtual one, allowing devices of any type at any location to be managed as if they all reside in the same cloud region or data center. All traffic is encrypted end-to-end and takes the most direct path available for minimum latency and maximum performance. The goals and design of ZeroTier are inspired by among other things the original [Google BeyondCorp](https://static.googleusercontent.com/media/research.google.com/en//pubs/archive/43231.pdf) paper and the [Jericho Forum](https://en.wikipedia.org/wiki/Jericho_Forum).

+Visit [ZeroTier's site](https://www.zerotier.com/) for more information and [pre-built binary packages](https://www.zerotier.com/download/). Apps for Android and iOS are available for free in the Google Play and Apple app stores.
 
 ### Getting Started
 
-ZeroTier's basic operation is easy to understand. Devices have 10-digit *ZeroTier addresses* like `89e92ceee5` and networks have 16-digit network IDs like `8056c2e21c000001`. All it takes for a device to join a network is its 16-digit ID, and all it takes for a network to authorize a device is its 10-digit address. Everything else is automatic.
+Everything in the ZeroTier world is controlled by two types of identifier: 40-bit/10-digit *ZeroTier addresses* and 64-bit/16-digit *network IDs*. A ZeroTier address identifies a node or "device" (laptop, phone, server, VM, app, etc.) while a network ID identifies a virtual Ethernet network that can be joined by devices.
 
-A "device" in our terminology is any "unit of compute" capable of talking to a network: desktops, laptops, phones, servers, VMs/VPSes, containers, and even user-space applications via our [SDK](https://github.com/zerotier/ZeroTierSDK).
+Another way of thinking about it is that ZeroTier addresses are port numbers on a giant planetary-sized smart switch while network IDs are VLANs to which these ports can be assigned. For more details read about VL1 and VL2 in [the ZeroTier manual](https://www.zerotier.com/manual/).
 
-For testing purposes we provide a public virtual network called *Earth* with network ID `8056c2e21c000001`. You can join it with:
+*Network controllers* are ZeroTier nodes that act as access control certificate authorities and configuration managers for virtual networks. The first 40 bits (or 10 digits) of a network ID is the ZeroTier address of its controller. You can create networks with our [hosted controllers](https://my.zerotier.com/) and web UI/API or [host your own](controller/) if you don't mind posting some JSON configuration info or writing a script to do so.
-
-    sudo zerotier-cli join 8056c2e21c000001
-
-Now wait about 30 seconds and check your system with `ip addr list` or `ifconfig`. You'll see a new interface whose name starts with *zt* and it should quickly get an IPv4 and an IPv6 address. Once you see it get an IP, try pinging `earth.zerotier.net` at `29.209.112.93`. If you've joined Earth from more than one system, try pinging your other machine. If you don't want to belong to a giant Ethernet party line anymore, just type:
-
-    sudo zerotier-cli leave 8056c2e21c000001
-
-The *zt* interface will disappear. You're no longer on the network.
-
-To create networks of your own, you'll need a network controller. ZeroTier One (for desktops and servers) includes controller functionality in its default build that can be configured via its JSON API (see [README.md in controller/](controller/)). ZeroTier provides a hosted solution with a nice web UI and SaaS add-ons at [my.zerotier.com](https://my.zerotier.com/). Basic controller functionality is free for up to 100 devices.
 
 ### Project Layout
 
+The base path contains the ZeroTier One service main entry point (`one.cpp`), self test code, makefiles, etc.
+
  - `artwork/`: icons, logos, etc.
  - `attic/`: old stuff and experimental code that we want to keep around for reference.
  - `controller/`: the reference network controller implementation, which is built and included by default on desktop and server build targets.
  - `debian/`: files for building Debian packages on Linux.
  - `doc/`: manual pages and other documentation.
+ - `docker/`: Dockerfile to build as a container for containerized Linux systems and Kubernetes clusters.
  - `ext/`: third party libraries, binaries that we ship for convenience on some platforms (Mac and Windows), and installation support files.
  - `include/`: include files for the ZeroTier core.
  - `java/`: a JNI wrapper used with our Android mobile app. (The whole Android app is not open source but may be made so in the future.)
  - `macui/`: a Macintosh menu-bar app for controlling ZeroTier One, written in Objective C.
  - `node/`: the ZeroTier virtual Ethernet switch core, which is designed to be entirely separate from the rest of the code and able to be built as a stand-alone OS-independent library. Note to developers: do not use C++11 features in here, since we want this to build on old embedded platforms that lack C++11 support. C++11 can be used elsewhere.
  - `osdep/`: code to support and integrate with OSes, including platform-specific stuff only built for certain targets.
+ - `rule-compiler/`: JavaScript rules language compiler for defining network-level rules.
  - `service/`: the ZeroTier One service, which wraps the ZeroTier core and provides VPN-like connectivity to virtual networks for desktops, laptops, servers, VMs, and containers.
- - `tcp-proxy/`: TCP proxy code run by ZeroTier, Inc. to provide TCP fallback (this will die soon!).
  - `windows/`: Visual Studio solution files, Windows service code for ZeroTier One, and the Windows task bar app UI.
 
-The base path contains the ZeroTier One service main entry point (`one.cpp`), self test code, makefiles, etc.
-
 ### Build and Platform Notes
 
 To build on Mac and Linux just type `make`. On FreeBSD and OpenBSD `gmake` (GNU make) is required and can be installed from packages or ports. For Windows there is a Visual Studio solution in `windows/'.
 
  - **Mac**
-   - Xcode command line tools for OSX 10.7 or newer are required.
+   - Xcode command line tools for OSX 10.8 or newer are required.
-   - Tap device driver kext source is in `ext/tap-mac` and a signed pre-built binary can be found in `ext/bin/tap-mac`. You should not need to build it yourself. It's a fork of [tuntaposx](http://tuntaposx.sourceforge.net) with device names changed to `zt#`, support for a larger MTU, and tun functionality removed.
  - **Linux**
-   - The minimum compiler versions required are GCC/G++ 4.9.3 or CLANG/CLANG++ 3.4.2.
+   - The minimum compiler versions required are GCC/G++ 4.9.3 or CLANG/CLANG++ 3.4.2. (Install `clang` on CentOS 7 as G++ is too old.)
    - Linux makefiles automatically detect and prefer clang/clang++ if present as it produces smaller and slightly faster binaries in most cases. You can override by supplying CC and CXX variables on the make command line.
-   - CentOS 7 ships with a version of GCC/G++ that is too old, but a new enough version of CLANG can be found in the *epel* repositories. Type `yum install epel-release` and then `yum install clang` to build there.
  - **Windows**
-   - Windows 7 or newer (and equivalent server versions) are supported. This *may* work on Vista but you're on your own there. Windows XP is not supported since it lacks many important network API functions.
+   - Windows 7 or newer is supported. This *may* work on Vista but isn't officially supported there. It will not work on Windows XP.
-   - We build with Visual Studio 2015. Older versions may not work with the solution file and project files we ship and may not have new enough C++11 support.
+   - We build with Visual Studio 2017. Older versions may not work. Clang or MinGW will also probably work but may require some makefile hacking.
-   - Pre-built signed Windows drivers are included in `ext/bin/tap-windows-ndis6`. The MSI files found there will install them on 32-bit and 64-bit systems. (These are included in our multi-architecture installer as chained MSIs.)
-   - Windows builds are more painful in general than other platforms and are for the adventurous.
  - **FreeBSD**
-   - Tested most recently on FreeBSD-11. Older versions may work but we're not sure.
+   - GNU make is required. Type `gmake` to build.
-   - GCC/G++ 4.9 and gmake are required. These can be installed from packages or ports. Type `gmake` to build.
  - **OpenBSD**

-   - OpenBSD lacks `getifmaddrs` (or any equivalent method) to get interface multicast memberships. As a result multicast will only work on OpenBSD for ARP and NDP (IP/MAC lookup) and not for other purposes.
+   - GNU make is required. Type `gmake` to build.
-   - Only tested on OpenBSD 6.0. Older versions may not work.
-   - GCC/G++ 4.9 and gmake are required and can be installed using `pkg_add` or from ports. They get installed in `/usr/local/bin` as `egcc` and `eg++` and our makefile is pre-configured to use them on OpenBSD.
 
 Typing `make selftest` will build a *zerotier-selftest* binary which unit tests various internals and reports on a few aspects of the build environment. It's a good idea to try this on novel platforms or architectures.

 Users behind certain types of firewalls and "symmetric" NAT devices may not able able to connect to external peers directly at all. ZeroTier has limited support for port prediction and will *attempt* to traverse symmetric NATs, but this doesn't always work. If P2P connectivity fails you'll be bouncing UDP packets off our relay servers resulting in slower performance. Some NAT router(s) have a configurable NAT mode, and setting this to "full cone" will eliminate this problem. If you do this you may also see a magical improvement for things like VoIP phones, Skype, BitTorrent, WebRTC, certain games, etc., since all of these use NAT traversal techniques similar to ours.
 
-If you're interested, there's a [technical deep dive about NAT traversal on our blog](https://www.zerotier.com/blog/?p=226). A troubleshooting tool to help you diagnose NAT issues is planned for the future as are uPnP/IGD/NAT-PMP and IPv6 transport.

 If a firewall between you and the Internet blocks ZeroTier's UDP traffic, you will fall back to last-resort TCP tunneling to rootservers over port 443 (https impersonation). This will work almost anywhere but is *very slow* compared to UDP or direct peer to peer connectivity.

 ZeroTier Release Notes
 ======
 
+# 2019-08-12 -- Version 1.4.2
+
+ * Fix high CPU use bug on some platforms
+ * Fix issues with PostgreSQL controller DB (only affects Central)
+ * Restore backward compatibility with MacOS versions prior to 10.13
+
+# 2019-07-29 -- Version 1.4.0
+
+### Major Changes
+
+ * Mac version no longer requires a kernel extension, instead making use of the [feth interfaces](https://apple.stackexchange.com/questions/337715/fake-ethernet-interfaces-feth-if-fake-anyone-ever-seen-this).
+ * Added support for concurrent multipath (multiple paths at once) with traffic weighting by link quality and faster recovery from lost links.
+ * Added under-the-hood support for QoS (not yet exposed) that will eventually be configurable via our rules engine.
+
+### Minor Changes and Bug Fixes
+
+ * Experimental controller DB driver for [LF](https://github.com/zerotier/lf) to store network controller data (LFDB.cpp / LFDB.hpp).
+ * Modified credential push and direct path push timings and algorithms to somewhat reduce "chattiness" of the protocol when idle. More radical background overhead reductions will have to wait for the 2.x line.
+ * Removed our beta/half-baked integration of Central with the Windows UI. We're going to do a whole new UI of some kind in the future at least for Windows and Mac.
+ * Fixed stack overflow issues on Linux versions using musl libc.
+ * Fixed some alignment problems reported on ARM and ARM64, but some reports we could not reproduce so please report any issues with exact chip, OS/distro, and ZeroTier version in use.
+ * Fixed numerous other small issues and bugs such as ARM alignment issues causing crashes on some devices.
+ * Windows now sets the adapter name such that it is consistent in both the Windows UI and command line utilities.
+
+# 2018-07-27 -- Version 1.2.12
+
+ * Fixed a bug that caused exits to take a long time on Mac due to huge numbers of redundant attempts to delete managed routes.
+ * Fixed a socket limit problem on Windows that caused the ZeroTier service to run out of sockets, causing the UI and CLI to be unable to access the API.
+ * Fixed a threading bug in the ZeroTier Core, albeit one that never manifested on the regular ZeroTier One service/client.
+ * Fixed a bug that could cause the service to crash if an authorized local client accessed an invalid URL via the control API. (Not exploitable since you needed admin access anyway.)
+
+# 2018-05-08 -- Version 1.2.10
+
+ * Fix bug loading `moons.d/` files for federated root operation.
+ * Fix compile problem with ZT_DEBUG on some versions of `clang`
+ * Fix slow network startup bug related to loading of `networks.d/` cache files
+
+# 2018-04-27 -- Version 1.2.8
+
+ * Linux version once again builds with PIE (position independent executable) flags
+ * Fixed bug in zerotier-idtool file sign and verify
+ * Fixed minor OSX app typo
+ * Merged alpha NetBSD support (mostly untested, so YMMV)
+ * Merged several minor typo and one-liner bug fixes
+
+# 2018-04-17 -- Version 1.2.6
+
+ * Features and Core Improvements
+    * Path selection has been overhauled to improve path stability, simplify code, and prepare for multi-path and trunking in the next major release.
+    * This version introduces remote tracing for remote diagnostics. Network controllers can set a node (usually the controller itself) to receive remote tracing events from all members of the network or from select members. Events are only sent if they pertain to a given network for security reasons.
+    * Multicast replication can now be done by designated multicast replicators on a network (flagged as such at the controller) rather than by the sender. Most users won't want this, but it's useful for specialized use cases on hub-and-spoke networks and for low-power devices.
+    * Cryptographic performance improvements on several platforms.
+    * Multithreaded performance improvements throughout the code base, including the use of an inline lightweight spinlock for low-contention resources.
+ * Bugs fixed
+    * Disappearing routes on Mac (GitHub issue #600)
+    * Route flapping and path instability in some dual-stack V4/V6 networks
+    * Blacklist (in local.conf) doesn't work reliably (GitHub issue #656)
+    * Connection instabilities due to unsigned integer overflows in timing comparisons (use int64_t instead of uint64_t)
+    * Binaries don't run on some older or lower-end 32-bit ARM chips (build problem)
+    * ARM NEON crypto code crashes (build problem)
+    * Fixed some lock ordering issues revealed by "valgrind" tool
+    * The "zerotier-idtool" command could not be accessed from "zerotier-one" via command line switch
+    * Leaking sockets on some platforms when uPnP/NAT-PMP is enabled
+    * Fixed two very rare multithreading issues that were only observed on certain systems
+ * Platform-Specific Changes
+    * MacOS
+        * Installer now loads the kernel extension right away so that High Sierra users will see the prompt to authorize it. This is done in the "Security & Privacy" preference pane and must be done directly on the console (not via remote desktop). On High Sierra and newer kexts must be authorized at the console via security settings system preferences pane.
+    * Windows
+        * The Windows installer should now install the driver without requiring a special prompt in most cases. This should make it easier for our packages to be accepted into and updated in the Chocolatey repository and should make it easier to perform remote installs across groups of machines using IT management and provisioning tools.
+        * The Windows official packages are now signed with an EV certificate (with hardware key).
+        * The Windows UI can now log into ZeroTier Central and join networks via the Central API.
+        * The `zerotier-idtool` command should now work on Windows without ugly hacks.
+        * Upgraded the installer version.
+        * Made a few changes to hopefully fix sporadic "will not uninstall" problems, though we cannot duplicate these issues ourselves.
+    * Linux
+        * Device names are now generated deterministically based on network IDs for all newly joined networks.
+    * Android
+        * Multicast now works on Android in most cases! Android apps can send and receive multicast and subscribe to multicast group IPs. Note that in some cases the app must bind to the specific correct interface for this to work.
+        * IPv6 can be disabled in UI for cases where it causes problems.
+
 # 2017-04-20 -- Version 1.2.4
 
  * Managed routes are now only bifurcated for the default route. This is a change in behavior, though few people will probably notice. Bifurcating all managed routes was causing more trouble than it was worth for most users.

 ## Major Bug Fixes in 1.2.0
 
  * **The Windows HyperV 100% CPU bug is FINALLY DEAD**: This long-running problem turns out to have been an issue with Windows itself, but one we were triggering by placing invalid data into the Windows registry. Microsoft is aware of the issue but we've also fixed the triggering problem on our side. ZeroTier should now co-exist quite well with HyperV and should now be able to be bridged with a HyperV virtual switch.
- * **Segmenation faults on musl-libc based Linux systems**: Alpine Linux and some embedded Linux systems that use musl libc (a minimal libc) experienced segmentation faults. These were due to a smaller default stack size. A work-around that sets the stack size for new threads has been added.

  * **Windows firewall blocks local JSON API**: On some Windows systems the firewall likes to block 127.0.0.1:9993 for mysterious reasons. This is now fixed in the installer via the addition of another firewall exemption rule.
  * **UI crash on embedded Windows due to missing fonts**: The MSI installer now ships fonts and will install them if they are not present, so this should be fixed.

-HTTP one-to-all test
-======
-
-*This is really internal use code. You're free to test it out but expect to do some editing/tweaking to make it work. We used this to run some massive scale tests of our new geo-cluster-based root server infrastructure prior to taking it live.*
-
-Before using this code you will want to edit agent.js to change SERVER_HOST to the IP address of where you will run server.js. This should typically be an open Internet IP, since this makes reporting not dependent upon the thing being tested. Also note that this thing does no security of any kind. It's designed for one-off tests run over a short period of time, not to be anything that runs permanently. You will also want to edit the Dockerfile if you want to build containers and change the network ID to the network you want to run tests over.
-
-This code can be deployed across a large number of VMs or containers to test and benchmark HTTP traffic within a virtual network at scale. The agent acts as a server and can query other agents, while the server collects agent data and tells agents about each other. It's designed to use RFC4193-based ZeroTier IPv6 addresses within the cluster, which allows the easy provisioning of a large cluster without IP conflicts.
-
-The Dockerfile builds an image that launches the agent. The image must be "docker run" with "--device=/dev/net/tun --privileged" to permit it to open a tun/tap device within the container. (Unfortunately CAP_NET_ADMIN may not work due to a bug in Docker and/or Linux.) You can run a bunch with a command like:
-
-    for ((n=0;n<10;n++)); do docker run --device=/dev/net/tun --privileged -d zerotier/http-test; done

-The new ZeroTier CLI!
-====
-
-With this update we've expanded upon the previous CLI's functionality, so things should seem pretty familiar. Here are some of the new features we've introduced:
-
- - Create and administer networks on ZeroTier Central directly from the console.
- - Service configurations, allows you to control local/remote instances of ZeroTier One
- - Identity generation and management is now part of the same CLI tool
-
-***
-## Configurations
-
-Configurations are a way for you to nickname and logically organize the control of ZeroTier services running locally or remotely (this includes ZeroTier Central!). They're merely groupings of service API url's and auth tokens. The CLI's settings data is contained within `.zerotierCliSettings`.
-
-For instance, you can control your local instance of ZeroTier One via the `@local` config. By default it is represented as follows:
-
-```
-"local": {
-      "auth": "7tyqRoFytajf21j2l2t9QPm5",
-      "type": "one",
-      "url": "http://127.0.0.1:9993/"
-}
-``` 
-
-As an example, if you issue the command `zerotier ls` is it implicitly stating `zerotier @local ls`. 
-
-With the same line of thinking, you could create a `@my.zerotier.com` which would allow for something like `zerotier @my.zerotier.com net-create` which talks to our hosted ZeroTier Central to create a new network.
-
-
-
-## Command families 
-
-- `cli-` is for configuring the settings data for the CLI itself, such as adding/removing `@thing` configurations, variables, etc.
-- `net-` is for operating on a *ZeroTier Central* service such as `https://my.zerotier.com`
-- `id-` is for handling ZeroTier identities.
-
-And those commands with no prefix are there to allow you to operate ZeroTier One instances either local or remote.
-
-***
-## Useful command examples
-
-*Add a ZeroTier One configuration:*
-
- - `zerotier cli-add-zt MyLocalConfigName https://127.0.0.1:9993/ <authtoken>`
-
-*Add a ZeroTier Central configuration:*
-
- - `zerotier cli-add-central MyZTCentralConfigName https://my.zerotier.com/ <centralAPIAuthtoken>`
-
-*Set a default ZeroTier One instance:*
-
- - `zerotier cli-set defaultOne MyLocalConfigName`
-
-*Set a default ZeroTier Central:*
-
- - `zerotier cli-set defaultCentral MyZTCentralConfigName`

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://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 CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU 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 <http://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
+<http://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 applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+*****************************************************************************
+Anode Protocol Specification Draft
+Version 0.8
+
+(c)2009-2010 Adam Ierymenko
+*****************************************************************************
+
+Table of Contents
+
+*****************************************************************************
+
+1. Introduction
+
+Anode provides three components that work together to provide a global,
+secure, and mobile addressing system for computer networks:
+
+1) An addressing system based on public key cryptography enabling network
+   devices or applications to assign themselves secure, unique, and globally
+   reachable network addresses in a flat address space.
+
+2) A system enabling network participants holding global addresses to locate
+   one another on local or global networks with "zero configuration."
+
+3) A communications protocol for communication between addressed network
+   participants that requires no special operating system support and no
+   changes to existing network infrastructure.
+
+Using Anode, both fixed and mobile applications and devices can communicate
+directly as if they were all connected to the same VPN. Anode restores the
+original vision of the Internet as a "flat" network where anything can talk
+to anything, and adds the added benefits of address mobility and strong
+protection against address spoofing and other protocol level attacks.
+
+1.1. Design Philosophy
+
+Anode's design philosophy is the classical "KISS" principle: "Keep It Simple
+Stupid." Anode's design principles are:
+
+#1: Do not try to solve too many problems at once, and stay in scope.
+
+Anode does not attempt to solve too many problems at once. It attempts to
+solve the problems of mobile addressing, address portability, and "flat"
+addressing in the presence of NAT or other barriers.
+
+It does not attempt to duplicate the full functionality of SSL, X.509, SSH,
+XMPP, an enterprise service bus, a pub/sub architecture, BitTorrent, etc. All
+of those protocols and services can be used over Anode if their functionality
+is desired.
+
+#2: Avoid state management.
+
+State multiplies the complexity and failure modes of network protocols. State
+also tends to get in the way of the achievement of new features implicitly
+(see principle #4). Avoid state whenever possible.
+
+#3: Avoid algorithm and dependency bloat.
+
+Anode uses only elliptic curve Diffie-Hellman (EC-DH) and AES-256. No other
+cryptographic algorithms or hash functions are presently necessary. This
+yields implementations compact enough for embedded devices.
+
+Anode also requires few or no dependencies, depending on whether the two
+needed cryptographic algorithms are obtained through a library or included.
+No other protocols or libraries are required in an implementation.
+
+#4: Achieve features implicitly.
+
+Use a simple stateless design that allows features to be achieved implicitly
+rather than specified explicitly. For example, Anode can do multi-homing and
+could be used to build a mesh network, but neither of these features is
+explicitly specified.
+
+*****************************************************************************
+
+2. Core Concepts and Algorithms
+
+This section describes addresses, zones, common algorithms, and other core
+concepts.
+
+2.1. Zones
+
+A zone is a 32-bit integer encoded into every Anode address. Zones serve to
+assist in the location of peers by address on global IP networks. They are
+not presently significant for local communications, though they could be
+used to partition addresses into groups or link them with configuration
+options.
+
+Each zone has a corresponding zone file which can be fetched in a number of
+ways (see below). A zone file is a flat text format dictionary of the format
+"key=value" separated by carriage returns. Line feeds are ignored, and any
+character may be escaped with a backslash (\) character. Blank lines are
+ignored.
+
+The following entries must appear in a zone file:
+
+n=<zone name>
+d=<zone description>
+c=<zone contact, e-mail address of zone administrator>
+r=<zone revision, monotonically increasing integer with each edit>
+ttl=<seconds before zone file should be re-checked for changes>
+
+Additional fields may appear as well, including fields specific to special
+applications or protocols supported within the zone. Some of these are
+defined in this document.
+
+Zone file fetching mechanisms are described below. Multiple mechanisms are
+specified to enable fallback in the event that one mechanism is not available.
+
+2.1.1. Zone File Retrieval
+
+Zone files are retrieved via HTTP, with the HTTP address being formed in one
+of two ways.
+
+The preferred DNS method:
+
+To fetch a zone file via DNS, use the zone ID to generate a host name and URI
+of the form:
+
+  http://a--XXXXXXXX.net/z
+
+The XXXXXXXX field is the zone ID in hexadecimal.
+
+The fallback IP method:
+
+For fallback in the absence of DNS, the zone ID can be used directly as an
+IPv4 or IPv4-mapped-to-IPv6 IP address. A URI is generated of the form:
+
+  http://ip_address/z
+
+Support for this method requires that a zone ID be chosen to correspond to a
+permanent IPv4 (preferably mappable to IPv6 space as well) IP address.
+
+2.1.2. Zone ID Reservation
+
+By convention, a zone ID is considered reserved when a domain of the form
+"a--XXXXXXXX.net" (where XXXXXXXX is the ID in hex) is registered.
+
+It is recommended that this be done even for zone IDs not used for global
+address location in order to globally reserve them.
+
+2.2. Addresses
+
+Anode addresses are binary strings containing a 32-bit zone ID, a public key,
+and possibly other fields. Only one address type is presently defined:
+
+|---------------------------------------------------------------------------|
+| Name         | Type ID | Elliptic Curve Parameters         | Total Length |
+|---------------------------------------------------------------------------|
+| ANODE-256-40 | 1       | NIST-P-256                        | 40           |
+|---------------------------------------------------------------------------|
+
+|---------------------------------------------------------------------------|
+| Name         | Binary Layout                                              |
+|---------------------------------------------------------------------------|
+| ANODE-256-40 | <type[1]><zone[4]><unused[2]><public key[33]>              |
+|---------------------------------------------------------------------------|
+
+The public key is a "compressed" form elliptic curve public key as described
+in RFC5480.
+
+The unused section of the address must be zero. These bytes are reserved for
+future use.
+
+2.2.1. ASCII Format For Addresses
+
+Addresses are encoded in ASCII using base-32, which provides a quotable and
+printable encoding that is of manageable length and is case-insensitive. For
+example, an ANODE-256-40 address is 64 characters long in base-32 encoding.
+
+2.3. Relaying
+
+An Anode peer may optionally relay packets to any other reachable peer.
+Relaying is accomplished by sending a packet to a peer with the recipient set
+to the final recipient. The receiving peer will, if relaying is allowed and if
+it knows of or can reach the recipient, forward the packet.
+
+No error is returned if relaying fails, so relay paths are treated as possible
+paths for communication until a return is received in the same way as direct
+paths.
+
+Relaying can be used by peers to send messages indirectly, locate one
+another, and determine network location information to facilitate the
+establishment of direct communications.
+
+Peers may refuse to relay or may limit the transmission rate at which packets
+can be relayed.
+
+2.3.1. Zone Relays
+
+If a zone's addresses are globally reachable on global IP networks, it must
+have one or more zone relays. These must have globally reachable public
+static IP addresses.
+
+Zone relays are specified in the zone file in the following format:
+
+  zr.<address checksum>=<ip>[,<ip>]:<udp port>:<tcp port>:<anode addresses>
+
+The address checksum is the sum of the bytes in the Anode address modulus
+the number of "zr" entries, in hexadecimal. For example, if a zone had four
+global relays its zone file could contain the lines:
+
+  zr.0=1.2.3.4:4343:4344:klj4j3...
+  zr.1=2.3.4.5:4343:4344:00194j...
+  zr.2=3.4.5.6:4343:4344:1j42zz...
+  zr.3=4.5.6.7:4343:4344:z94j1q...
+
+The relay would be chosen by taking the sum of the bytes in the address
+modulo 4. For example, if the bytes of an address sum to 5081 then relay
+zr.1 would be used to communicate with that address.
+
+If more than one IP address is listed for a given relay, the peer must choose
+at random from among the addresses of the desired type (IPv4 or IPv6).
+
+Each relay must have one Anode address for every address type supported within
+the zone. (At present there is only one address type defined.)
+
+Peers should prefer UDP and fall back to TCP only if UDP is not available.
+
+To make itself available, a peer must make itself known to its designated zone
+relay. This is accomplished by sending a PING message.
+
+2.4. Key Agreement and Derivation
+
+Key agreement is performed using elliptic curve Diffie-Hellman. This yields
+a raw key whose size depends on the elliptic curve parameters in use.
+
+The following algorithm is used to derive a key of any length from a raw
+key generated through key agreement:
+
+1) Zero the derived key buffer.
+2) Determine the largest of the original raw key or the derived key.
+3) Loop from 0 to the largest length determined in step 2, XOR each byte of
+   the derived key buffer with the corresponding byte of the original key
+   buffer with each index being modulus the length of the respective buffer.
+
+2.5. Message Authentication
+
+For message authentication, CMAC-AES (with AES-256) is used. This is also
+known in some literature as OMAC1-AES. The key is derived from key agreement
+between the key pair of the sending peer and the address of the recipient.
+
+2.6. AES-DIGEST
+
+To maintain cryptographic algorithm frugality, a cryptographic hash function
+is constructed from the AES-256 cipher. This hash function uses the common
+Davis-Meyer construction with Merkle-Damgård length padding.
+
+It is described by the following pseudocode:
+
+  byte previous_digest[16] 
+  byte digest[16] = { 0,0,... } 
+  byte block[32] = { 0,0,... } 
+  integer block_counter = 0 
+
+  ; digest message 
+  for each byte b of message 
+    block[block_counter] = b 
+    block_counter = block_counter + 1 
+    if block_counter == 32 then 
+      block_counter = 0 
+      save digest[] in previous_digest[] 
+      encrypt digest[] with aes-256 using block[] as 256-bit aes-256 key 
+      xor digest[] with previous_digest[] 
+    end if 
+  next 
+
+  ; append end marker, do final block 
+  block[block_counter] = 0x80 
+  block_counter = block_counter + 1 
+  zero rest of block[] from block_counter to 15 
+  save digest[] in previous_digest[] 
+  encrypt digest[] with aes-256 using block[] as 256-bit aes-256 key 
+  xor digest[] with previous_digest[] 
+
+  ; Merkle-Damgård length padding 
+  zero first 8 bytes of block[] 
+  fill last 8 bytes of block[] w/64-bit length in big-endian order 
+  save digest[] in previous_digest[] 
+  encrypt digest[] with aes-256 using block[] as 256-bit aes-128 key 
+  xor digest[] with previous_digest[] 
+
+  ; digest[] now contains 128-bit message digest 
+
+2.7. Short Address Identifiers (Address IDs)
+
+A short 8-byte version of the Anode address is used in the protocol to reduce
+transmission overhead when both sides are already aware of the other's full
+address.
+
+The short address identifier is formed by computing the AES-DIGEST of the
+full address and then XORing the first 8 bytes of the digest with the last
+8 bytes to yield an 8-byte shortened digest.
+
+2.8. DNS Resolution of Anode Addresses
+
+Anode addresses can be saved in DNS TXT records in the following format:
+
+anode:<address in base32 ASCII encoding>
+
+This permits Anode addresses to be resolved from normal DNS host name.
+
+2.9. Packet Transmission Mechanisms
+
+2.9.1. UDP Transmission
+
+The recommended method of sending Anode packets is UDP. Each packet is simply
+sent as a UDP packet.
+
+2.9.2. TCP Transmission
+
+To send packets over TCP, each packet is prefixed by its size as a 16-bit
+integer.
+
+2.9.3. HTTP Transmission
+
+Anode packets may be submitted in HTTP POST transactions for transport over
+networks where HTTP is the only available protocol.
+
+Anode packets are simply prefixed with a 16-byte packet size and concatenated
+together just as they are in a TCP stream. One or more packets may be sent
+with each HTTP POST transaction for improved performance.
+
+Since this method is intended for use in "hostile" or highly restricted
+circumstances, no additional details such as special headers or MIME types
+are specified to allow maximum flexibility. Peers should ignore anything
+other than the payload.
+
+2.10. Endpoints
+
+An endpoint indicates a place where Anode packets may be sent. The following
+endpoint types are specified:
+
+|---------------------------------------------------------------------------|
+| Endpoint Type | Description   | Address Format                            |
+|---------------------------------------------------------------------------|
+| 0x00          | Unspecified   | (none)                                    |
+| 0x01          | Ethernet      | <mac[6]>                                  |
+| 0x02          | UDP/IPv4      | <ip[4]><port[2]>                          |
+| 0x03          | TCP/IPv4      | <ip[4]><port[2]>                          |
+| 0x04          | UDP/IPv6      | <ip[16]><port[2]>                         |
+| 0x05          | TCP/IPv6      | <ip[16]><port[2]>                         |
+| 0x06          | HTTP          | <null-terminated full URI>                |
+|---------------------------------------------------------------------------|
+
+Endpoints are encoded by beginning with a single byte indicating the endpoint
+type followed by the address information required for the given type.
+
+Note that IP ports bear no relationship to Anode protocol ports.
+
+2.11. Notes
+
+All integers in the protocol are transmitted in network (big endian) byte
+order.
+
+*****************************************************************************
+
+3. Common Packet Format
+
+A common header is used for all Anode packets:
+
+|---------------------------------------------------------------------------|
+| Field                    | Length | Description                           |
+|---------------------------------------------------------------------------|
+| Hop Count                | 1      | 8-bit hop count (not included in MAC) |
+| Flags                    | 1      | 8-bit flags                           |
+| MAC                      | 8      | 8 byte shortened CMAC-AES of packet   |
+| Sender Address           | ?      | Full address or short ID of sender    |
+| Recipient Address        | ?      | Full address or short ID of recipient |
+| Peer IDs                 | 1      | Two 4-bit peer IDs: sender, recipient |
+| Message Type             | 1      | 8-bit message type                    |
+| Message                  | ?      | Message payload                       |
+|---------------------------------------------------------------------------|
+
+3.1. Hop Count
+
+The hop count begins at zero and must be incremented by each peer that relays
+the packet to another peer. The hop count must not wrap to zero at 255.
+
+Because the hop count is modified in transit, it is not included in MAC
+calculation or authentication.
+
+The hop count is used to prioritize endpoints that are direct over endpoints
+that involve relaying, or to prioritize closer routes over more distant
+ones.
+
+3.2. Flags and Flag Behavior
+
+|---------------------------------------------------------------------------|
+| Flag  | Description                                                       |
+|---------------------------------------------------------------------------|
+| 0x01  | Sender address fully specified                                    |
+| 0x02  | Recipient address fully specified                                 |
+| 0x04  | Authentication error response                                     |
+|---------------------------------------------------------------------------|
+
+If flag 0x01 is set, then the sender address will be the full address rather
+than a short address identifier. The length of the address can be determined
+from the first byte of the address, which always specifies the address type.
+Flag 0x02 has the same meaning for the recipient address.
+
+A peer must send fully specified sender addresses until it receives a response
+from the recipient. At this point the sender may assume that the recipient
+knows its address and use short a short sender address instead. This
+assumption should time out, with a recommended timeout of 60 seconds.
+
+There is presently no need to send fully specified recipient addresses, but
+the flag is present in case it is needed and must be honored.
+
+Flag 0x04 indicates that this is an error response containing a failed
+authentication error. Since authentication failed, this packet may not have
+a valid MAC. Packets with this flag must never have any effect other than
+to inform of an error. This error, since it is unauthenticated, must never
+have any side effects such as terminating a connection.
+
+3.3. MAC
+
+The MAC is calculated as follows:
+
+1) Temporarily set the 64-bit/8-byte MAC field in the packet to the packet's
+   size as a 64-bit big-endian integer.
+2) Calculate the MAC for the entire packet (excluding the first byte) using
+   the key agreed upon between the sender and the recipient, resulting in a
+   16 byte full CMAC-AES MAC.
+3) Derive the 8 byte packet MAC by XORing the first 8 bytes of the full 16
+   byte CMAC-AES MAC with the last 8 bytes. Place this into the packet's MAC
+   field.
+
+3.4. Peer IDs
+
+Peer IDs provide a method for up to 15 different peers to share an address,
+each with a unique ID allowing packets to be routed to them individually.
+
+A peer ID of zero indicates "any" or "unspecified." Real peers must have a
+nonzero peer ID. In the normal single peer per address case, any peer ID may
+be used. If multiple peers are to share an address, some implementation-
+dependent method must be used to ensure that each peer has a unique peer ID.
+
+Relaying peers must follow these rules based on the recipient peer ID when
+relaying messages:
+
+ - IF the peer ID is zero or if the peer ID is not known, the message must
+   be forwarded to a random endpoint for the given recipient address.
+ - IF the peer ID is nonzero and matches one or more known endpoints for the
+   given recipient address and peer ID, the message must only be sent to
+   a matching endpoint.
+
+A receiving peer should process any message that it receives regardless of
+whether its recipient peer ID is correct. The peer ID is primarily for relays.
+
+Peers should typically send messages with a nonzero recipient peer ID when
+responding to or involved in a conversation with a specific peer (e.g. a
+streaming connection), and send zero recipient peer IDs otherwise.
+
+3.5. Short Address Conflict Disambiguation
+
+In the unlikely event of two Anode addresses with the same short identifier,
+the recipient should use MAC validation to disambiguate. The peer ID must not
+be relied upon for this purpose.

+|---------------------------------------------------------------------------|
+| Flags             | 1      | 8-bit flags                                  |

+| NAT-T options     | ?      | Options related to specified NAT-T mode      |
+|---------------------------------------------------------------------------|
+
+EPI stands for EndPoint Identification, and is sent to notify another peer of
+a network endpoint where the sending peer is reachable.
+
+If the receiving peer is interested in communicating with the sending peer,
+the receiving peer must send EPC_REQ to the sending peer at the specified
+endpoint to check the validity of that endpoint. The endpoint is learned if a
+valid EPC is returned.
+
+If the endpoint in EPI is unspecified, the actual source of the EPI message
+is the endpoint. This allows EPI messages to be broadcast on a local LAN
+segment to advertise the presence of an address on a local network. EPI
+broadcasts on local IP networks must be made to UDP port 8737.
+
+Usually EPI is sent via relays (usually zone relays) to inform a peer of an
+endpoint for direct communication.
+
+There are presently no flags, so flags must be zero.

+| Endpoint          | ?      | Endpoint type and address information        |
+|---------------------------------------------------------------------------|
+
+When a NETID_REQ message is received, the recipient attempts to echo it back
+as a NETID message to the specified endpoint address. If the endpoint is
+unspecified, the recipient must fill it in with the actual origin of the
+NETID_REQ message. This allows a peer to cooperate with another peer (usually
+a zone relay) to empirically determine its externally visible network
+address information.
+
+A peer may ignore NETID_REQ or respond with an error if it does not allow
+relaying.
+
+4.2.9. NETID
+

+| Endpoint Address  | ?      | Endpoint Address (size depends on type)      |
+|---------------------------------------------------------------------------|
+
+NETID is sent in response to NETID_REQ to the specified endpoint address. It
+always contains the endpoint address to which it was sent.

+|---------------------------------------------------------------------------|
+
+A datagram is a UDP-like message without flow control or delivery assurance.

+*****************************************************************************
+
+5. Stream Protocol
+
+The stream protocol is very similar to TCP, though it omits some features
+that are not required since they are taken care of by the encapsulating
+protocol. SCTP was also an inspiration in the design.
+
+5.1. Message Types
+
+|---------------------------------------------------------------------------|

+|---------------------------------------------------------------------------|
+| S_OPEN    | 20 | Initiate a streaming connection (like TCP SYN)           |
+| S_CLOSE   | 21 | Terminate a streaming connection (like TCP RST/FIN)      |
+| S_DATA    | 22 | Data packet                                              |
+| S_ACK     | 23 | Acknowedge receipt of one or more data packets           |
+| S_DACK    | 24 | Combination of DATA and ACK                              |
+|---------------------------------------------------------------------------|
+
+5.2. Message Details
+
+5.2.1. S_OPEN
+
+|---------------------------------------------------------------------------|
+| Field             | Length | Description                                  |
+|---------------------------------------------------------------------------|
+| Sender Link ID    | 2      | 16-bit sender link ID                        |
+| Destination Port  | 2      | 16-bit destination port                      |
+| Window Size       | 2      | 16-bit window size in 1024-byte increments   |
+| Init. Seq. Number | 4      | 32-bit initial sequence number               |
+| Flags             | 1      | 8-bit flags                                  |
+|---------------------------------------------------------------------------|
+
+The OPEN message corresponds to TCP SYN, and initiates a connection. It
+specifies the initial window size for the sender and the sender's initial
+sequence number, which should be randomly chosen to prevent replay attacks.
+
+If OPEN is successful, the recipient sends its own OPEN to establish the
+connetion. If OPEN is unsuccessful, CLOSE is sent with its initial and current
+sequence numbers equal and an appropriate reason such as "connection refused."
+
+The sender link ID must be unique for a given recipient.
+
+If flag 01 is set, the sender link ID is actually a source port where the
+sender might be listening for connections as well. This exactly duplicates
+the behavior of standard TCP. Otherwise, the sender link ID is simply an
+arbitrary number that the sender uses to identify the connection with this
+recipient and there is no port of origin. Ports of origin are optional for
+Anode streaming connections to permit greater scalability.
+
+5.2.2. S_CLOSE
+
+|---------------------------------------------------------------------------|
+| Field             | Length | Description                                  |
+|---------------------------------------------------------------------------|
+| Sender Link ID    | 2      | 16-bit sender link ID                        |
+| Destination Port  | 2      | 16-bit destination port                      |
+| Flags             | 1      | 8-bit flags                                  |
+| Reason            | 1      | 8-bit close reason                           |
+| Init. Seq. Number | 4      | 32-bit initial sequence number               |
+| Sequence Number   | 4      | 32-bit current sequence number               |
+|---------------------------------------------------------------------------|
+
+The CLOSE message serves a function similar to TCP FIN. The initial sequence
+number is the original starting sequence number sent with S_OPEN, while the
+current sequence number is the sequence number corresponding to the close
+and must be ACKed to complete the close operation. The use of the initial
+sequence number helps to serve as a key to prevent replay attacks.
+
+CLOSE is also used to indicate a failed OPEN attempt. In this case the current
+sequence number will be equal to the initial sequence number and no ACK will
+be expected.
+
+There are currently no flags, so flags must be zero.
+
+The reason field describes the reason for the close:
+
+|---------------------------------------------------------------------------|
+| Reason Code | Description                                                 |
+|---------------------------------------------------------------------------|
+| 00          | Application closed connection                               |
+| 01          | Connection refused                                          |
+| 02          | Protocol error                                              |
+| 03          | Timed out                                                   |
+|---------------------------------------------------------------------------|
+
+Established connections will usually be closed with reason 00, while reason
+01 is usually provided if an OPEN is received but the port is not bound.
+
+5.2.3. S_DATA
+

+| Sequence Number   | 4      | 32-bit sequence number                       |
+| Payload           | ?      | Data payload                                 |
+|---------------------------------------------------------------------------|
+
+The DATA message carries a packet of data, with the sequence number
+determining order. The sequence number is monotonically incremented with
+each data packet, and wraps at the maximum value of an unsigned 32-bit
+integer.
+
+5.2.4. S_ACK
+
+|---------------------------------------------------------------------------|
+| Field             | Length | Description                                  |
+|---------------------------------------------------------------------------|
+| Sender Link ID    | 2      | 16-bit sender link ID                        |
+| Destination Port  | 2      | 16-bit destination port                      |
+| Window Size       | 2      | 16-bit window size in 1024-byte increments   |
+| Acknowledgements  | ?      | One or more acknowledgements (see below)     |
+|---------------------------------------------------------------------------|
+
+Each acknowledgement is a 32-bit integer followed by an 8-bit integer (5 bytes
+total). The 32-bit integer is the first sequence number to acknowledge, and
+the 8-bit integer is the number of sequential following sequence numbers to
+acknowledge. For example "1, 4" would acknowledge sequence numbers 1, 2, 3,
+and 4.
+
+5.2.5. S_DACK
+
+|---------------------------------------------------------------------------|
+| Field             | Length | Description                                  |
+|---------------------------------------------------------------------------|
+| Sender Link ID    | 2      | 16-bit sender link ID                        |
+| Destination Port  | 2      | 16-bit destination port                      |
+| Window Size       | 2      | 16-bit window size in 1024-byte increments   |
+| Num. Acks         | 1      | 8-bit number of acknowledgements             |
+| Acknowledgements  | ?      | One or more acknowledgements                 |
+| Payload           | ?      | Data payload                                 |
+|---------------------------------------------------------------------------|
+
+The DACK message combines ACK and DATA, allowing two peers that are both
+transmitting data to efficiently ACK without a separate packet.

-Dockerized Linux Build Farm
-======
-
-This subfolder contains Dockerfiles and a script to build Linux packages for a variety of Linux distributions. It's also an excellent way to test your CPU fans and stress test your disk.
-
-Running `build.sh` with no arguments builds everything. You can run `build.sh` with the name of a distro (e.g. centos-7) to only build that. Both 32 and 64 bit packages are built except where no 32-bit version of the distribution exists.
-
-The `make-apt-repos.sh` and `make-rpm-repos.sh` scripts build repositories. They may require some editing for outside-of-ZeroTier use, and be careful with the apt one if you have an existing *aptly* configuration.
