scripts-dyndns

This package provides scripts that assist with updating a DynDNS hostname and other related tasks.

The scripts are packaged using npm for convenience, so you'll need to install Node.js if you haven't already.

Installation

Install curl and the following Perl modules (for example, using your package manager or CPAN Minus):

• Getopt::Long::Descriptive
• LWP::UserAgent
• Net::DNS::Resolver

Then:

sudo npm install -g scripts-dyndns

Similarly, to uninstall:

sudo npm rm -g scripts-dyndns
