This is a simple bash script that can update the IP address at yDNS by simply cURL'ing the API update resource.
- bash
- cURL
Copy the script to a desired location. To configure the script, you can either edit it by editing YDNS_USER, YDNS_PASSWD and YDNS_HOST within, or you can use the -u, -p and -H command line options respectively. For example:
$ ./updater.sh -u myuser -p password -H myhost.ydns.eu
Simply run the script with - or without command line options, depending on whether you'd like to specify the configuration as command line arguments. You can use the -V option to enable verbose output (useful for debugging). The script will exit with code 0 on success, with code 1 on input errors and 90 or 91 on other issues.
You can list all available command line options using the -h option.
- Added support for command line arguments.
- Added support for detecting IP address changes. The IP address is only updated when it has changed. A temporary file (default
/tmp/ydns_last_ip) is used to store the "last known" IP address to decide whether it has been changed since last usage.
