Hello -stable:

Can someone tell me why I keep getting log-messages like this?
It sometimes seems to "break" Netscape (waiting trying to
resolve localhost).  I'm using a "dummy" hostname of
"myname.my.domain."  This has been happening for *months* with
no (or not much?) ill-effect, but I would like to clean that
up if possible & there must be something I'm not quite getting
right for config...  What is happening here? It appears that
I am rejecting a UDP DNS query from "myself." (?) What
might/would be a Good & Proper Way To Fix This?

Oh, I'm running 4.3-RC as of (cvsupped/built) 1 April 2001.
Other information on request I guess... <shrug>

Many thanks,

-kc
