Tiger Tips: Make Spotlight Index a Network Drive
There's a very useful new hint over at Mac OS X Hints that shows you how to enable Spotlight indexing of drives on your network.
By default, Spotlight only indexes drives connected locally to your Mac, but now if you have something like a NSLU2 set up to share files between multiple computers, all you need to do is execute a few commands via the Terminal (located in /Applications/Utilities/) to force Spotlight to start indexing these types of drives.
