Use omshell/omapi to set hostname for ddns?

[Brad Dameron]

I have been using this little app instead of expect. A heck of a lot cleaner and easier to use:

Or if you prefer perl:

Hope this helps.
 
Brad

Okay, after a lot more searching, here's the answer to my own question:

To use omshell to set ddns info (in my case, just an A record), do something like this:

   $con->send("set statements=\"ddns-hostname=\\\"$hname\\\"; ".
                               "ddns-domainname=\\\"$domain\\\";\"\n");
   $con->expect(1,'eof');

(I'm using expect with omshell).
