-  - Add a script +  * Super simple to enable and no configuration required 
-  - Add a scheduler entry to run the script+  * Also supports NTP without configuring the SNTP Client
  
-===== Create a Script =====+Dynamic DNS and NTP service that's simple to set up and needs no scripts or scheduled tasks.  The only obvious down side is that the host name is not memorable.
  
-Copy and paste this script at the CLI to generate a script to be scheduled:+To make a more memorable hostname, you can create a CNAME record in another DNS domain name that you control using this DNS Name as the target.
