On Microsoft Windows OS, at the command prompt, I issue the command ipconfig /flushdns to flush out the DNS resolver cache.
On Ubuntu 12.10, what is the corresponding command?

You do that by restarting nscd
To install nscd Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command below:
sudo apt-get install nscd
To flush DNS Cache do:
sudo /etc/init.d/nscd restart

1Synaptic has this in the description: "A daemon which handles passwd, group and host lookups for running programs and caches the results for the next query. You should install this package only if you use slow services like LDAP, NIS or NIS+." So is that why it isn't installed by default? (I don't have it installed.)– user25656Mar 23, 2013 at 16:40

Ubuntu doesn't include nscd in the default installation. I really don't know why, but I guess its because it doesn't cache dns names by default.– MitchMar 23, 2013 at 17:15
