I'm trying to use nscd (Nameservices
Cache Daemon) to
cache dns locally so I can stop using bind to do it. I've gotten it started and ntpd seems to attempt to use it. But everything else for hosts seems to ignore it. e.g if I do dig apache.org 3 times none of them will hit the
cache. I'm viewing the
cache stats using nscd -g to determine whether it's been used. I've also turned the debug log level up to see if I can see it hitting and the queries don't even hit nscd.
