I was actually looking to flush the client side cache. It seems that
AIX does not cache nameserver entries on the client side. Is there a
way to confirm this? Can I run some tests to confirm?
After verifying you are not running a local caching-only name server
(ie cheching your resolv.conf file), write a little program that asks
for the same name a few times in a row. While that program is running
use tcpdump or the like to watch traffic to/from port 53. If you see
the DNS query for the same name more than once (ie as many times as
your program asks for the name) then there is no caching.
