CentOS5.3怎么清除DNS缓存

Posted 2023-03-18

不是高手。共同探讨。
一般情况下在linix下，DNS客户端只负责转发和接受查询的功能，应该并不缓存。

可不可以理解nscd？默认是不启动的。
In Linux, the nscd daemon manages the DNS cache. To flush the DNS cache, restart the nscd daemon. To restart the nscd daemon, use the command `/etc/init.d/nscd restart`.

如果是浏览器的话
» Start your Firefox, enter “about:config” at the location bar and press enter. If you are using Firefox 3 then u’ll see a warning page, just click “I’ll be careful, i promise” button.
» U’ll see a lot of record, just right click at the blank place and select “New” -> “Integer”
» Enter “network.dnsCacheExpiration” as the preference name and “0″ as the integer value
» Right click and select “New” -> “Integer” again
» This time enter “network.dnsCacheEntries” as preference name and “0″ as integer value
» Done, you just disable the firefox dns cache
