Are you trying to make sure that the clients do not use cached lookups? If so you could use max-cache-ttl and max-ncache-ttl with a very low ttl like 1 second. Although then you still have a problem with the client itself caching the lookup. -- Matthew Martz CentOS Mirror Admin mdmartz at gflug.net
