I'm looking for a way to flush the local DNS cache on a CentOS 6.
The system is not running any DNS server or anything, and I wish to let every DNS query go out to the configured nameserver, even for the duplicate ones.
Most of what I found online tell me to do
service nscd restart, reload or do
nscd -i hosts. However, none seems to flush the cache.
So I'm wondering if anyone has an idea on how I might do this. Is there some kind of switch in the kernel I need to flip? Any kind of work around is fine as well.
