# Description:
#   Update the DNS A Record with your public IP address for the one.com host.
#
# Recommendation:
#  - Create a separate user that can only access the DNS records.
#  - Create a cron tab to run this script every 30 minutes:
#       crontab -e
#       */30 * * * * ~/Scripts/update-dns-one.com.sh  >/dev/null 2&>1
#  - To get the Sub Domain Id you will have to manually update the domain and record the network traffic using your browser
#
# Require:
#   sudo apt-get install wget gawk curl ca-certificates

Hi guys, one.com changed their website since I last created the script. I'm no longer using one.com DNS Services anymore and switched to cloudflare. They have many APIs to manage the DNS entries so it's easier to maintain.

I suggest you might do the same, their services are for free so there is no extra cost.

For the moment I'm not planning to update the script.

Cheers,
Glenn
