Why?

I've done some research and found that the cheapest DUC domain for my KiwiSDR is *.ovh provided by OVH company. Registration of new domain cost approximately €1.99, renewal - €2.99.

How to?

1. You need to have your DUC domain, username and password for management. Please check this instruction
2. Logging into your server via SSH and move to /root directory cd /root
3. Download script wget https://raw.githubusercontent.com/kovalroma/ovh-domain-dynamic-dns-update/master/ovh-update.sh
4. Add your HOSTNAME, USERNAME, PASSWORD. nano ./ovh-update.sh, Ctrl+X, Yes
5. Make script executive chmod +x ./ovh-update.sh
6. Add 15 minutes interval to check your IP and update if necessary crontab -e add line */15 * * * * /root/ovh-update.sh
7. Go to Log tab in your KiwiSDR admin panel and check your status.
