How to flush DNS cache

[labbe5]

Some times you are trouble to reach some of the sites due to DNS issue, it may be your local DNS cache was corrupt. For this kind of situation, you need to restart your operating system DNS caching service.

For Dog users, type in terminal :

$ sudo /etc/init.d/dns-clean start

There are other ways for flushing DNS cache, but Dog users need only using above command line. You know your DNS cache is flushed if Restoring resolver state... [ OK ] is showing.

If, after flushing your DNS cache, you still have a problem reaching a specific website, try using a public DNS (Google : 8.8.8.8 and secondary DNS 8.8.4.4).
