update-ip 0.2.1

An extensible dynamic IP updater.

An extensible Python utility to automatically update your IP address with dynamic DNS services. This initial release only supports WebFaction, but other services will be coming soon. This utility was designed to be run periodically through a scheduling utility like cron to keep your IP address current.

Installation

To install:

pip install update-ip

Initial Setup

A small text file is created to keep track of your current IP address. Before beginning regular use, update-ip needs to be run manually first with a list of domain names to update the IP address for:

$ update-ip -f /tmp/public_ip.txt -u myusername -p mypass \
-d my.awesomedomain.com,even.coolerdomain.com webfaction

The filename is the name of the file that will be created and then read each time the utility is run. The username and password are for the dynamic DNS service. The domains should be separated by commas, with no spaces. The service name is the name of a module within update_ip/services/.

Automatic Domains

After the first run, the text file should be in place. You can then run the script without specifically indicating the domains to update. When your IP changes, the script will check each domain on the dynamic DNS service and determine which ones are currently using your old domain. It will use those domains when it updates the service to your new IP.
