This is an implementation of a dynamic dns server in node.js. Its records can be updated through the DynDNS update protocol.

This application has these features:

• IPv4 DNS server to resolve a hostname to its IPv4 address (A-Record)
• Update the records

• via DynDNS protocol
• by checking an individual username and passwort for each host record
• over http and https (when activated)

• Save the records to a file to have the data available on restart

To run the application, you need the file dyndnsdata. It contains all dns records:

[
{"host":"samplehost","user":"username","pass":"passw0rd","ip":"8.9.2.1"},
{"host":"secondhost","user":"alice","pass":"p4ssw0rd","ip":"123.4.5.6"}
]

The file dnd.js provides these options:

The udp port for the dns server (default value: 53).

The tcp port for the http update service (default value: 1090)

The tcp port for the https update service (default value: 1091)

A boolean value to control, whether the https update service should run.

var options = {
 key: fs.readFileSync('server.key'),
 cert: fs.readFileSync('server.crt')
};

These two values tell the https service, which files it has to use for the server certificate and the certificate key.

This is the name of the permanent data file. It saves the hostnames, usernames, passwords and latest IP addresses.
