[](https://travis-ci.org/cmur2/dyndnsd)
|
||||
|
||||
A small, lightweight and extensible DynDNS server written with Ruby and Rack.
|
||||
|
||||
|
||||
## Description
|
||||
|
||||
dyndnsd.rb aims to implement a small [DynDNS-compliant](https://help.dyn.com/remote-access-api/) server in Ruby supporting IPv4 and IPv6 addresses. It has an integrated user and hostname database in its configuration file that is used for authentication and authorization. Besides talking the DynDNS protocol it is able to invoke a so-called *updater*, a small Ruby module that takes care of supplying the current hostname => ip mapping to a DNS server.

dyndnsd.rb is aimed to implement a small [DynDNS-compliant](http://dyn.com/support/developers/api/) server in Ruby. It has an integrated user and hostname database in it's configuration file that is used for authentication and authorization. Besides talking the DynDNS protocol it is able to invoke an so-called *updater*, a small Ruby module that takes care of supplying the current host => ip mapping to a DNS server.
|
||||
|
||||
There are currently two updaters shipped with dyndnsd.rb:
|
||||
- `zone_transfer_server` that uses [DNS zone transfers via AXFR (RFC5936)](https://tools.ietf.org/html/rfc5936) to allow any secondary nameserver(s) to fetch the zone contents after (optionally) receiving a [DNS NOTIFY (RFC1996)](https://tools.ietf.org/html/rfc1996) request
|
||||
- `command_with_bind_zone` that writes out a zone file in BIND syntax onto the current system and invokes a user-supplied command afterwards that is assumed to trigger the DNS server (not necessarily BIND since its zone files are read by other DNS servers, too) to reload its zone configuration
|
||||
|
||||
Because of the mechanisms used, dyndnsd.rb is known to work only on \*nix systems.
|
||||
|
||||
See the [changelog](CHANGELOG.md) before upgrading. The older version 1.x of dyndnsd.rb is still available on [branch dyndnsd-1.x](https://github.com/cmur2/dyndnsd/tree/dyndnsd-1.x).

## Using dyndnsd.rb with [NSD](https://www.nlnetlabs.nl/nsd/)
|
||||
|
||||
### Docker image
|
||||
NSD is a nice opensource, authoritative-only, low-memory DNS server that reads BIND-style zone files (and converts them into it's own database) and has a simple config file.
|
||||
|
||||
There is an officially maintained [Docker image for dyndnsd](https://hub.docker.com/r/cmur2/dyndnsd) available at Dockerhub. The goal is to have a minimal secured image available (currently based on Alpine) that works well for the `zone_transfer_server` updater use case.
|
||||
|
||||
Users can make extensions by deriving from the official Docker image or building their own.
|
||||
|
||||
The Docker image consumes the same configuration file in YAML format as the gem, inside the container it needs to be mounted/available as `/etc/dyndnsd/config.yml`. The following YAML should be used as a base and extended with user's settings:
|
||||
A feature NSD is lacking is the [Dynamic DNS update](https://tools.ietf.org/html/rfc2136) functionality BIND offers but one can fake it using the following dyndnsd.rb config:
|
||||
|
||||
```yaml
|
||||
host: "0.0.0.0"
|
||||
port: 8080
|
||||
# omit the logfile: option so logging to STDOUT will happen automatically
|
||||
db: "/var/lib/dyndnsd/db.json"
|
||||
|
||||
# User's settings for updater and permissions follow here!
|
||||
```
|
||||
|
||||
more ports might be needed depending on if DNS zone transfer is needed
|
||||
|
||||
Run the Docker image exposing the DynDNS-API on host port 8080 via:
|
||||
|
||||
```bash
|
||||
docker run -d --name dyndnsd \
|
||||
-p 8080:8080 \
|
||||
-v /host/path/to/dyndnsd/config.yml:/etc/dyndnsd/config.yml \
|
||||
-v /host/ptherpath/to/dyndnsd/datadir:/var/lib/dyndnsd \
|
||||
cmur2/dyndnsd:vX.Y.Z
|
||||
```
|
||||
|
||||
*Note*: You may need to expose more than just port 8080 e.g. if you use the `zone_transfer_server` which can be done by appending additional `-p 5353:5353` flags to the `docker run` command.
|
||||
|
||||
|
||||
|
||||
## Using dyndnsd.rb with any nameserver via DNS zone transfers (AXFR)
|
||||
|
||||
By using [DNS zone transfers via AXFR (RFC5936)](https://tools.ietf.org/html/rfc5936) any secondary nameserver can retrieve the DNS zone contents from dyndnsd.rb and serve them to clients.
|
||||
To speedup propagation after changes dyndnsd.rb can issue a [DNS NOTIFY (RFC1996)](https://tools.ietf.org/html/rfc1996) to inform the nameserver that the DNS zone contents changed and should be fetched even before the time indicated in the SOA record is up.
|
||||
Currently, dyndnsd.rb does not support any authentication for incoming DNS zone transfer request, so it should be isolated from the internet on these ports.
|
||||
|
||||
This approach has several advantages:
|
||||
- dyndnsd.rb can be used in *hidden primary* fashion isolated from client's DNS traffic and does not need to implement full nameserver features
|
||||
- any existing, production-grade, caching, geo-replicated nameserver setup can be used to pull DNS zone contents from the *hidden primary* dyndnsd.rb and serve it to clients
|
||||
- any nameserver(s) and dyndnsd.rb do not need to be located on the same host
|
||||
|
||||
Example dyndnsd.rb configuration:
|
||||
|
||||
```yaml
|
||||
host: "0.0.0.0"
|
||||
port: 8245 # the DynDNS.com alternative HTTP port
|
||||
db: "/opt/dyndnsd/db.json"

|
||||

## Advanced topics
|
||||
|
||||
|
||||
### Update URL
|
||||
|
||||
The update URL you want to tell your clients (humans or scripts ^^) consists of the following
|
||||
|
||||
http[s]://[USER]:[PASSWORD]@[DOMAIN]:[PORT]/nic/update?hostname=[HOSTNAMES]&myip=[MYIP]&myip6=[MYIP6]
|
||||
http[s]://[USER]:[PASSWORD]@[DOMAIN]:[PORT]/nic/update?hostname=[HOSTNAMES]&myip=[MYIP]
|
||||
|
||||
where:
|
||||
|
||||
* the protocol depends on your (web server/proxy) settings
|
||||
* `USER` and `PASSWORD` are needed for HTTP Basic Auth and valid combinations are defined in your config.yaml
|
||||
* `DOMAIN` should match what you defined in your config.yaml as domain but may be anything else when using a web server as proxy
|
||||
* `PORT` depends on your (web server/proxy) settings
|
||||
* `HOSTNAMES` is a required list of comma-separated FQDNs (they all have to end with your config.yaml domain) the user wants to update
|
||||
* `MYIP` is optional and the HTTP client's IP address will be used if missing
|
||||
* `MYIP6` is optional but if present also requires presence of `MYIP`
|
||||
|
||||
|
||||
### IP address determination
|
||||
|
||||
The following rules apply:
|
||||
|
||||
* use any IP address provided via the `myip` parameter when present, or
|
||||
* use any IP address provided via the `X-Real-IP` header e.g. when used behind HTTP reverse proxy such as nginx, or
|
||||
* use any IP address used by the connecting HTTP client
|
||||
|
||||
If you want to provide an additional IPv6 address as myip6 parameter, the `myip` parameter containing an IPv4 address has to be present, too! No automatism is applied then.
|
||||
|
||||
* the protocol depends on your (webserver/proxy) settings
|
||||
* USER and PASSWORD are needed for HTTP Basic Auth and valid combinations are defined in your config.yaml
|
||||
* DOMAIN should match what you defined in your config.yaml as domain but may be anything else when using a webserver as proxy
|
||||
* PORT depends on your (webserver/proxy) settings
|
||||
* HOSTNAMES is a required list of comma separated FQDNs (they all have to end with your config.yaml domain) the user wants to update
|
||||
* MYIP is optional and the HTTP client's address will be used if missing
|
||||
|
||||
### SSL, multiple listen ports
|
||||
|
||||
Use a web server as a proxy to handle SSL and/or multiple listen addresses and ports. DynDNS.com provides HTTP on port 80 and 8245 and HTTPS on port 443.

|
||||
|
||||
### Init scripts
|
||||
|
||||
### Startup
|
||||
|
||||
There is a [Dockerfile](docs/Dockerfile) that can be used to build a Docker image for running dyndnsd.rb.
|
||||
|
||||
The [Debian 6 init.d script](docs/debian-6-init-dyndnsd) assumes that dyndnsd.rb is installed into the system ruby (no RVM support) and the config.yaml is at /opt/dyndnsd/config.yaml. Modify to your needs.
|
||||
|
||||
|
||||
### Monitoring
|
||||
|
||||
For monitoring dyndnsd.rb uses the [metriks](https://github.com/eric/metriks) framework and exposes several metrics like the number of unauthenticated requests, requests that did (not) update a hostname, etc. By default, the most important metrics are shown in the [proctitle](https://github.com/eric/metriks#proc-title-reporter, butt you can also configure a [Graphite](https://graphiteapp.org/) backend for central monitoring or the [textfile_reporter](https://github.com/prometheus/node_exporter/#textfile-collector) which outputs Graphite-style metrics that are also compatible with Prometheus to a file.
|
||||
|
||||
```yaml
|
||||
host: "0.0.0.0"
|
||||
port: 8245 # the DynDNS.com alternative HTTP port
|
||||
db: "/opt/dyndnsd/db.json"
|
||||
domain: "dyn.example.org"
|
||||
# configure the Graphite backend to be used instead of proctitle
|
||||
graphite:
|
||||
host: localhost # defaults for host and port of a carbon server
|
||||
port: 2003
|
||||
prefix: "my.graphite.metrics.naming.structure.dyndnsd"
|
||||
# OR configure the textfile reporter instead of Graphite/proctitle
|
||||
textfile:
|
||||
file: /path/to/file.prom
|
||||
prefix: "my.graphite.metrics.naming.structure.dyndnsd"
|
||||
# configure the updater, here we use command_with_bind_zone, params are updater-specific
|
||||
updater:
|
||||
name: "command_with_bind_zone"
|
||||
params:
|
||||
zone_file: "dyn.zone"
|
||||
command: "echo 'Hello'"
|
||||
ttl: "5m"
|
||||
dns: "dns.example.org."
|
||||
email_addr: "admin.example.org."
|
||||
# user database with hostnames a user is allowed to update
|
||||
users:
|
||||
# 'foo' is username, 'secret' the password
|
||||
foo:
|
||||
password: "secret"
|
||||
hosts:
|
||||
- foo.example.org
|
||||
- bar.example.org
|
||||
test:
|
||||
password: "ihavenohosts"
|
||||
```
|
||||
|
||||
|
||||
### Tracing (experimental)
|
||||
|
||||
For tracing, dyndnsd.rb is instrumented using the [OpenTelemetry](https://opentelemetry.io/docs/ruby/) framework and will emit span tracing data for the most important operations happening during the request/response cycle. Using an [instrumentation for Rack](https://github.com/open-telemetry/opentelemetry-ruby/tree/main/instrumentation/rack) allows handling incoming OpenTelemetry parent span information properly (when desired, turned off by default to reduce attack surface).
|
||||
|
||||
Currently, the [OpenTelemetry trace exporter](https://github.com/open-telemetry/opentelemetry-ruby/tree/main/exporter/jaeger) for [CNCF Jaeger](https://github.com/jaegertracing/jaeger) can be enabled via dyndnsd.rb configuration. Alternatively, you can also enable other exporters via the environment variable `OTEL_TRACES_EXPORTER`, e.g. `OTEL_TRACES_EXPORTER=console`.
|
||||
|
||||
```yaml
|
||||
host: "0.0.0.0"
|
||||
port: 8245 # the DynDNS.com alternative HTTP port
|
||||
db: "/opt/dyndnsd/db.json"
|
||||
domain: "dyn.example.org"
|
||||
# enable and configure tracing using the (currently only) tracer jaeger
|
||||
tracing:
|
||||
trust_incoming_span: false # default value, change to accept incoming OpenTelemetry spans as parents
|
||||
service_name: "my.dyndnsd.identifier" # default unset, will be populated by OpenTelemetry
|
||||
jaeger: true # enables the Jaeger AgentExporter
|
||||
# configure the updater, here we use command_with_bind_zone, params are updater-specific
|
||||
updater:
|
||||
name: "command_with_bind_zone"
|
||||
params:
|
||||
zone_file: "dyn.zone"
|
||||
command: "echo 'Hello'"
|
||||
ttl: "5m"
|
||||
dns: "dns.example.org."
|
||||
email_addr: "admin.example.org."
|
||||
# user database with hostnames a user is allowed to update
|
||||
users:
|
||||
# 'foo' is username, 'secret' the password
|
||||
foo:
|
||||
password: "secret"
|
||||
hosts:
|
||||
- foo.example.org
|
||||
- bar.example.org
|
||||
test:
|
||||
password: "ihavenohosts"
|
||||
```
|
||||
|
||||
The [Debian 6 init.d script](init.d/debian-6-dyndnsd) assumes that dyndnsd.rb is installed into the system ruby (no RVM support) and the config.yaml is at /opt/dyndnsd/config.yaml. Modify to your needs.
