To execute the script simply adapt the variables in the CONFIG section (in inwx-dyndns.rb) and run
ruby inwx-dyndns.rb
A logfile is automatically created and aged once it reaches a size of 1MB (up to 10 revisions of the file).
You may use cron to run the script periodically and update your dns entry.
Here is an example for running the script every 5 minutes:
*/5 * * * * cd ~/inwx-dyndns-ruby/; ruby inwx-dyndns.rb
See the Arch Linux Wiki for more information about cron.
