Hi again!
Different question today: What's the best way you recommend to reliably
get an authoritative Fully Qualified Domain Name for a given machine?
I've been using gethostbyaddr() and doing a reverse lookup on the IP
address, but sometimes that comes back with "woof" instead of
"woof.uiuc.edu" if the /etc/hosts file isn't set up correctly.
On the machine itself, I can use the Net::Domain::getfqdn() call, but that
sometimes gives spurious results depending on the contents of
/etc/resolv.conf. And in any event, if other folks are doing a
gethostbyaddr(), the name they each come back with for the same machine may
not agree with each other.
So. Any thoughts?
Mitch
