. conf determines the action of the cache daemon.Clear dnsmasq dns Cache Dnsmasq is a lightweight DNS, TFTP, and DHCP server. It aims to provide paired DNS and DHCP services for the LAN. Dnsmasq accepts DNS queries and responds to them from a small local cache or forwards them to a real recursive DNS server. The software is also installed on many cheap routers to cache DNS queries. You only need to restart the dnsmasq service to clear the DNS Cache: $ Sudo/etc/init. d/dnsmasq restart Or # S

How to empty the DNS cache for LinuxI. Empty DNS cache under Linux There are usually two ways to implement a DNS cache implementation under Linux:One is to manage the DNS cache with the DNS cache program NSCD (Name Service cache daemon).One way to implement DNS caching is to use bind to erect the caching Name server. If you are clearing the cache on the NSCD, you can restart the NSCD service to achieve the effect of clearing the DNS cache. With this command:# Service NSCD RestartOr#/etc/init.d/n

For example, "update-policy" can obtain control to dynamically update data. Extensive support of TSIGs (shared keys) for access control, for example, "update-policy" can be used for fine grained access control of dynamic updates.
