node-ddns-client
A commandline Dynamic DNS client for Node DDNS
Commandline
npm install --global ddns-cli
ddns \
--hostname example.com \
--answer 127.0.0.1 \
--type A \
--token token.txt \
--services ns1.foo-dns-service.com,ns2.foo-dns-service.com
free domains for testing
There are two domains available:
*.daplie.me
viaddns
*.testing.letssecure.org
viaddns-testing
You can choose your own subdomain:
# <whatever>.daplie.me
ddns \
--hostname aj \
--email '[email protected]' \
--answer 127.0.0.1 \
--type A
# assigns aj.daplie.me
Or get a randomly assigned subdomain in the format rubber-duck-42
# <random>.daplie.me
ddns \
--hostname aj.daplie.me \
--email '[email protected]' \
--answer 127.0.0.1 \
--type A
# assigns rubber-duck-42.daplie.me
Here's an example using ddns-testing
:
# <random>.testing.letssecure.org
ddns-testing \
--random \
--email '[email protected]' \
--answer 127.0.0.1 \
--type A
# assigns rubber-duck-42.letssecure.org
Note: these domains are restricted to a single device (see below)
multiple devices
** The --device
option**
In the real world you probably have several servers with several IP addresses that all respond to the same domain.
The device
option allows you to specify a different device which will add an ip record rather than
overwrite an existing ip record.
ddns \
--hostname example.com \
--answer 127.0.0.1 \
--device server-3
--type A \
--token token.txt \
--services ns1.foo-dns-service.com,ns2.foo-dns-service.com
API
ddns.update({ servers, pathname, ddns })
NOTE: the API will change in a future version (currently there are some bad naming conventions), but I'll keep backwards compatibility.
var ddns = require('ddns-cli');
ddns.update({
servers: [
'ns1.example.net'
, 'ns2.example.net'
, 'ns3.example.net'
, 'ns4.example.net'
]
, pathname: '/api/com.daplie.dns/ddns'
, ddns: [
{ "name": "example.com"
, "value": "127.0.0.1"
, "type": "A"
, "priority": undefined
, "token": "ef13...." // jwt token
, "ttl": 600 // 10 minutes
, "device": "server-7"
}
, { "name": "example.com"
, "value": "::1"
, "type": "AAAA"
, "priority": undefined
, "token": "ef13...." // jwt token
, "ttl": 600 // 10 minutes
, "device": "server-7"
}
]
});
curl
For the curious curlers who would like to implement this in another language:
JWT="xyz.abc.xyz"
IP="127.0.0.1"
HOSTNAME="example.com"
DEVICE="foo"
curl -X POST https://ns1.example.net/api/com.daplie.dns/ddns \
-H "Authorization: Bearer $JWT" \
-H "Content-Type: application/json" \
-d '[
{ "name": "'$HOSTNAME'", "value": "'$IP'", "type": "A", "token": "'$JWT'", "ttl": 600, "device": "'$DEVICE'" }
]'
Note: the API may change to accept an array of tokens and an array of domains separately, but it will probably still need an Authorization Bearer token.
