ping retains old address

[M.Ashcraft at epixtech.com]

/etc/.name_service_door is a door to nscd -- the Name Services Cache
Daemon.  nscd caches DNS lookups as well as the /etc/hosts /etc/password
and /etc/group files for quicker lookup.  It's behavior, including timeout
of entries, is configured in /etc/nscd.conf.

Removal of the file disabled this "feature" on your system.

Also note that nscd is an uncommitted feature that may be modified or
removed in a future Solaris releases.

I'm running BIND 8.2.2p5 on Solaris 2.8, I'm logged in on the box.  I was
adding a new A and PTR RR and fat-fingered it.  Both forward and reverse RR
were wrong in a consistent manner.

Should be:     foo  192.168.242.157      (alive)
Mistake:  foo  192.168.242.187 (non-existent)

After kill -HUP (sorry, that new-fangled ndc stuff is still a paradigm leap
away)
I 'ping -sn' the box, realized the mistake, re-edited, and kill -HUP again.
Now
nslookup returns the correct address (157); but when I 'ping -sn' again,
ping
retained the old address (187).

     % ping -sn foo
     PING foo (192.168.242.187): 56 data bytes
     ^C
     ----foo PING Statistics----
     21 packets transmited, 0 packets received, 100% packet loss

Hmmm.. I waited a bit, ping again, same thing.  Why this cranky behavior?
I trussed ping, it does an open() on /etc/.name_service_door.  Never one to
let something I don't understand get in my way, I waxed that file to
oblivion.
Now ping works with the correct address.  What am I seeing here?  BTW that
door is not recreated, though subsequent pings still try to open it.
Cannot
reproduce ping's bad behavior since the waxing of that door.  What's it
for?
