I have been using ddclient and it has problem that causes a
watchdog timeout followed by the NIC being reset with down/up many times 
a hour.
All those other dynamic DNS ports are way over complicated for such a 
simple task.

I wrote this KISS script so I can have complete control of this very 
simple process.

Entering set -x [script name] on the command line is really a trace of 
the commands in the script as they execute. This is no help as already 
know the endless loop is what is keeping it connected to the terminal 
that issued the execute command. Was hoping the rc.d service script 
would break that and is reason I was asking for help with that script as 
the subject states.

Thanks anyhow for taking time to answer.
