Smarter Parental Controls

If you've been using the parental controls options in Mac OS X to lock your child out of using a particular computer late at night, but would like to employ a more clever technique to limit Internet access, turn to MAC address filtering on an Apple base station.

To do this, launch AirPort Utility, select your base station, and click Manual Setup. In the Access Control view, choose Time Access to turn on MAC filtering. You'll need to enter the MAC address of the particular computer, which (in 10.5 Leopard and 10.6 Snow Leopard) you can find in the Network System Preferences pane: click AirPort in the adapter list, and click Advanced. The AirPort ID is the MAC address.

 
 

Paths to POPs

Paths to POPs -- John Baxter <jwbaxter@olympus.net>, a colleague of ours out on the Olympic Peninsula, notes that POPs aren't the only way for providers to build networks. Similar to the UK solution we mention above, U.S. ISPs have another option:

You may also be calling an auto-forwarding telephone number, which has a certain number of "paths" (connections) to some remote collection of modems. These are charged (to the operator) on a per-path basis or otherwise. They can be used to good advantage where there isn't sufficient demand to justify setting up a POP as defined last week in NetBITS.
