Linux doesn't cache dns names by default.

You would need to install nscd.

Why do you need to flush the dns?

So flushing the dns cache (which Ubuntu doesn't use by default) will allow you more "privacy" ?

Hrm, ok.

Caching DNS resolutions is mostly a Windows thing. Ubuntu can do it, but you would need to install the nscd daemon (it is not installed by default) or be running your own DNS server.

If you are really worried about it just restart networking:


sudo /etc/init.d/networking restart

will that do the trick?

There is no cache to clear, all that does it just restart the networking service.

You could stick it in a cronjob.
