Clearing the DNS cache under Linux

Usually we can not open the page through the domain name, it is possible to cause the DNS cache (DNS resolved IP address changed), the workaround is as follows:

Method One: $nslookup ecafe.pub (here is the domain you want to open)

Method Two: $sudo/etc/init.d/nscd restart

Or: $service nscd restart

Or: $service nscd Reload

If NSCD cannot execute, install NSCD First, the command is as follows: $sudo apt-get install NSCD
