the Work as stated below:
To Reproduce the Work, to incorporate the Work into one or more
Collections, and to Reproduce the Work as incorporated in the
Collections
To create and Reproduce Adaptations provided that any such Adaptation,
including any translation in any medium, takes reasonable steps to
clearly label, demarcate or otherwise identify that changes were made to
the original Work. For example, a translation could be marked \"The
original work was translated from English to Spanish,\" or a
modification could indicate \"The original work has been modified.\"
To Distribute and Publicly Perform the Work including as incorporated in
Collections.
To Distribute and Publicly Perform Adaptations. The above rights may be
exercised in all media and formats whether now known or hereafter
devised. The above rights include the right to make such modifications
as are technically necessary to exercise the rights in other media and
formats. This License constitutes the entire agreement between the
parties with respect to the Work licensed here. There are no
understandings, agreements or representations with respect to the Work
not specified here. Licensor shall not be bound by any additional
provisions that may appear in any communication from You. This License
may not be modified without the mutual written agreement of the Licensor
and You. All rights not expressly granted by Licensor are hereby
reserved, including but not limited to the rights set forth in
Non-waivable Compulsory License Schemes, Waivable Compulsory License
Schemes, and Voluntary License Schemes in the restrictions.
# Restrictions
The license granted in the license grant above is expressly made subject
to and limited by the following restrictions:
You may Distribute or Publicly Perform the Work only under the terms of
this License. You must include a copy of, or the Uniform Resource
Identifier (URI) for, this License with every copy of the Work You
Distribute or Publicly Perform. You may not offer or impose any terms on
the Work that restrict the terms of this License or the ability of the
recipient of the Work to exercise the rights granted to that recipient

section in any manner that is primarily intended for or directed toward
commercial advantage or private monetary compensation unless you meet
the following requirements.
i. You are a worker-owned business or worker-owned collective.
ii. after tax, all financial gain, surplus, profits and benefits
produced by the business or collective are distributed among the
worker-owners unless a set amount is to be allocated towards
community projects as decided by a previously-established consensus
agreement between the worker-owners where all worker-owners agreed.
iii. You are not using such rights on behalf of a business other than
those specified in (i) or (ii) above, nor are using such rights as
a proxy on behalf of a business with the intent to circumvent the
aforementioned restrictions on such a business.

##
If You Distribute, or Publicly Perform the Work or any Adaptations or
Collections, You must, unless a request has been made by any Licensor to
remove credit from a Collection or Adaptation, keep intact all copyright
notices for the Work and provide, reasonable to the medium or means You
are utilizing:
i. the name of the Original Author (or pseudonym, if applicable) if
supplied, and/or if the Original Author and/or Licensor designate
another party or parties (e.g., a sponsor institute, publishing
entity, journal) for attribution (\"Attribution Parties\") in
Licensor\'s copyright notice, terms of service or by other
reasonable means, the name of such party or parties;
ii. the title of the Work if supplied;
iii. to the extent reasonably practicable, the URI, if any, that
Licensor to be associated with the Work, unless such URI does not
refer to the copyright notice or licensing information for the
Work; and,
iv. in the case of an Adaptation, a credit identifying the use of the
Work in the Adaptation (e.g., \"French translation of the Work by
Original Author,\" or \"Screenplay based on original Work by
Original Author\").
If any Licensor has sent notice to request removing credit, You must, to
the extent practicable, remove any credit as requested. The credit
required by this Section may be implemented in any reasonable manner;
provided, however, that in the case of an Adaptation or Collection, at a
minimum such credit will appear, if a credit for all contributing
authors of the Adaptation or Collection appears, then as part of these
credits and in a manner at least as prominent as the credits for the
other contributing authors. For the avoidance of doubt, You may only use
the credit required by this Section for the purpose of attribution in
the manner set out above and, by exercising Your rights under this
License, You may not implicitly or explicitly assert or imply any
connection with, sponsorship or endorsement by the Original Author,
Licensor and/or Attribution Parties, as appropriate, of You or Your use
of the Work, without the separate, express prior written permission of
the Original Author, Licensor and/or Attribution Parties.
Non-waivable Compulsory License Schemes. In those jurisdictions in which
the right to collect royalties through any statutory or compulsory
licensing scheme cannot be waived, the Licensor reserves the exclusive
right to collect such royalties for any exercise by You of the rights
granted under this License
Waivable Compulsory License Schemes. In those jurisdictions in which the
right to collect royalties through any statutory or compulsory licensing
scheme can be waived, the Licensor reserves the exclusive right to
collect such royalties for any exercise by You of the rights granted
under this License if Your exercise of such rights is for a purpose or
use which is otherwise than noncommercial as permitted under Commercial
Restrictions and otherwise waives the right to collect royalties through
any statutory or compulsory licensing scheme.
Voluntary License Schemes. The Licensor reserves the right to collect
royalties, whether individually or, in the event that the Licensor is a
member of a collecting society that administers voluntary licensing
schemes, via that society, from any exercise by You of the rights
granted under this License that is for a purpose or use which is
otherwise than noncommercial as permitted under the license grant.
Except as otherwise agreed in writing by the Licensor or as may be
otherwise permitted by applicable law, if You Reproduce, Distribute or
Publicly Perform the Work either by itself or as part of any Adaptations
or Collections, You must not distort, mutilate, modify or take other
derogatory action in relation to the Work which would be prejudicial to
the Original Author\'s honor or reputation. Licensor agrees that in
those jurisdictions (e.g. Japan), in which any exercise of the right
granted in the license grant of this License (the right to make
Adaptations) would be deemed to be a distortion, mutilation,
modification or other derogatory action prejudicial to the Original
Author\'s honor and reputation, the Licensor will waive or not assert,
as appropriate, this Section, to the fullest extent permitted by the
applicable national law, to enable You to reasonably exercise Your right
under the license grant of this License (right to make Adaptations) but
not otherwise.
Do not make any legal claim against anyone accusing the Work, with or
without changes, alone or with other works, of infringing any patent
claim.
# Representations Warranties and Disclaimer
UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE
EXCLUSION OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
# Limitation on Liability
EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE LAW, IN NO EVENT WILL
LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR ANY SPECIAL,
INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES ARISING OUT OF
THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS BEEN ADVISED
OF THE POSSIBILITY OF SUCH DAMAGES.
# Termination
This License and the rights granted hereunder will terminate
automatically upon any breach by You of the terms of this License.
Individuals or entities who have received Adaptations or Collections
from You under this License, however, will not have their licenses
terminated provided such individuals or entities remain in full
compliance with those licenses. The Sections on definitions, fair
dealing rights, representations, warranties, and disclaimer, limitation
on liability, termination, and revised license versions will survive any
termination of this License.
Subject to the above terms and conditions, the license granted here is
perpetual (for the duration of the applicable copyright in the Work).
Notwithstanding the above, Licensor reserves the right to release the
Work under different license terms or to stop distributing the Work at
any time; provided, however that any such election will not serve to
withdraw this License (or any other license that has been, or is
required to be, granted under the terms of this License), and this
License will continue in full force and effect unless terminated as
stated above.
# Revised License Versions
This License may receive future revisions in the original spirit of the
license intended to strengthen This License. Each version of This
License has an incrementing version number.
Unless otherwise specified like in the below subsection The Licensor has
only granted this current version of This License for The Work. In this
case future revisions do not apply.
The Licensor may specify that the latest available revision of This
License be used for The Work by either explicitly writing so or by
suffixing the License URI with a \"+\" symbol.
The Licensor may specify that The Work is also available under the terms
of This License\'s current revision as well as specific future
revisions. The Licensor may do this by writing it explicitly or
suffixing the License URI with any additional version numbers each
separated by a comma.
# Miscellaneous
Each time You Distribute or Publicly Perform the Work or a Collection,
the Licensor offers to the recipient a license to the Work on the same
terms and conditions as the license granted to You under this License.
Each time You Distribute or Publicly Perform an Adaptation, Licensor
offers to the recipient a license to the original Work on the same terms
and conditions as the license granted to You under this License.
If the Work is classified as Software, each time You Distribute or
Publicly Perform an Adaptation, Licensor offers to the recipient a copy
and/or URI of the corresponding Source Code on the same terms and
conditions as the license granted to You under this License.
If the Work is used as a Network Service, each time You Distribute or
Publicly Perform an Adaptation, or serve data derived from the Software,
the Licensor offers to any recipients of the data a copy and/or URI of
the corresponding Source Code on the same terms and conditions as the
license granted to You under this License.
If any provision of this License is invalid or unenforceable under
applicable law, it shall not affect the validity or enforceability of
the remainder of the terms of this License, and without further action
by the parties to this agreement, such provision shall be reformed to
the minimum extent necessary to make such provision valid and
enforceable.
No term or provision of this License shall be deemed waived and no
breach consented to unless such waiver or consent shall be in writing
and signed by the party to be charged with such waiver or consent.
This License constitutes the entire agreement between the parties with
respect to the Work licensed here. There are no understandings,
agreements or representations with respect to the Work not specified
here. Licensor shall not be bound by any additional provisions that may
appear in any communication from You. This License may not be modified
without the mutual written agreement of the Licensor and You.
The rights granted under, and the subject matter referenced, in this
License were drafted utilizing the terminology of the Berne Convention
for the Protection of Literary and Artistic Works (as amended on
September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996 and
the Universal Copyright Convention (as revised on July 24, 1971). These
rights and subject matter take effect in the relevant jurisdiction in
which the License terms are sought to be enforced according to the
corresponding provisions of the implementation of those treaty
provisions in the applicable national law. If the standard suite of
rights granted under applicable copyright law includes additional rights
not granted under this License, such additional rights are deemed to be
included in the License; this License is not intended to restrict the
license of any rights under applicable law.

# dyndnsd # CloudFlare DDNS update tool
This is a simple daemon that runs in the background and checks for your public ![](https://github.com/zbrox/cloudflare-ddns/workflows/Build/badge.svg)
IP regularily. If it changes, the service sets the corresponding DNS record. The
service supports both IPv4 and IPv6 addresses.
## Installation This is a simple CLI you can use to continuously update an A DNS record for a domain using CloudFlare's free DDNS service.
Use the package manager [cargo](https://doc.rust-lang.org/cargo/) to install ## Options
dyndnsd.
```bash ```
cargo install dyndnsd -k, --key <auth-key> The auth key you need to generate in your Cloudflare profile
-c, --cache <cache> Cache file for previously reported IP address (if skipped the IP will be reported on every execution)
-d, --domain <domain> The domain for which you want to report the current IP address
-e, --email <email> Your Cloudflare login email
-z, --zone <zone> The zone in which your domain is (usually that is your base domain name)
``` ```
## Usage ## Cloudflare Setup
### Config
`dyndnsd` expects to find a config file at `/etc/dyndnsd/config.toml`. You need to do some preparatory work in Cloudflare. Firstly this assumes you're using Cloudflare already to manage the DNS records for your domain.
As you can see from the path, the configuration should be a toml file. A sample ### Initial DNS setup
could look like this:
```toml You need to add a type `A` DNS record for your domain. The `Name` field you should fill in with the name of the subdomain. If you don't want to use a subdomain just type `@` then the base domain will be used. Then change the `Proxy status` field to be not `Proxied` but `DNS only`. This will allow you to input `0.0.0.0` in the `IPv4 Address` field. Then click the save button. You might need to wait sometime before the DNS record propagates.
zone = "example.com"
domain = "example.example.com"
ipv4 = true # defaults to true
ipv6 = true # defaults to false
interval = 15 # seconds, defaults to 60
# You can use cloudflare ### API key
[dns_provider_config.cloudflare]
secret = "secretkey"
# Or you can use RFC 2136 with TSIG We need to authenticate ourselves in front of the Cloudflare API. To do so we need to an auth key to pass along as a password together with our login email. You can find the global API key in `My profile > API Tokens`.
[dns_provider_config.rfc2136]
addr = "udp://1.2.3.4:53"
key_name = "test"
key = "test"
algorithm = "hmac-sha256"
```
As you can see, we have a token here. This token needs to have access to at
least:
- reading you account zones (for getting the zone ID from the zone name)
- reading and writing to the DNS zone (for first fetching the records and then
modifying them.
Aside of the token, you also have to prepare some DNS records before running
this: If you enabled IPv4 support, there needs to be a DNS `A` record for the
configured domain already, and if you enabled IPv6 support, you need a DNS
`AAAA` record set on the configured domain. The service will not create new
records, it just modifies existing records.
### Running
To run the service, just call the binary. You can optionally set the `RUST_LOG`
env var to configure the log level:
```bash
RUST_LOG=info dyndnsd
```

## Attribution
This work is derived from
[cloudflare-ddns](https://github.com/zbrox/cloudflare-ddns), a commandline
utility fullfilling the same purpose. It's written by Rostislav Raykov
<z@zbrox.org> and available under the MIT license at the link above.
This fork has made major changes to the project, to the extent where most of
the code has been rewritten and the tool is quite different:
- Runs as a service instead of in a cron job
- Supports IPv6
- Homegrown Cloudflare API client has been replaced with a library which
supports multiple providers
