Ugh, I’m so tired of seeing people posting technical advice that is just plain wrong! Why does it seem like it is always Ubuntu users? Has Ubuntu just brought over so many pathetic former MCSE’s that don’t understand the way an operating system works but are full of themselves and so feel the need to post things like this? I really don’t understand this.

In any case, nscd is NOT installed by default in Ubuntu. It makes absolutely no sense to install it, only to be able to reset it. If it is not installed, then DNS is not cached directly by libc. Firefox, for example, maintains its own DNS cache, and the only way to clear it is to restart the browser. The OS does not cache DNS unless you install nscd manually, as this article advocates. It’s just common sense here, people… *sigh*

Guys, read the text you post to…
—————-8 Install nscd using the following command 8——————-
You can not find the command when it is not installed of course…
