This script may be used by people having a "dynamic IP" ISP and administrating their own DNS server.
It sends a dynamic update to update a specific record within your DNS zone (using Bind nsupdate binary)
Sample usage:
nshome -k Khome.example.com.private -n home.example.com -s ns.example.com
This will send an update to ns.example.com to overwrite home.example.com to your current IP address.
It assumes the zone is correctly configured on the server part to accept updates to example.com with the home.examplecom.private key
You can add the -p5 option to check for IP every 5 minutes and only send update if it changed
You might wish to checkout the MANUAL.rst file to see how to set up your DNS server
Since the script needs the nsupdate binary, you'll need to install it:
- Debian/Ubuntu:
apt-get install dnsutils bind9utils - MacOS:
brew install bind
