Use omshell/omapi to set hostname for ddns?

[Steve van der Burg]

Yeah, I keep meaning to look into the perl OMAPI modules.  I've got about 10k dynamic host objects that are in each of my two dhcp servers, and the thought of how long it would take to push all of those in at once, if I lost the leases file, is pretty scary.

Thanks for the pointer.
