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.


NSCA HTTPd Security Hole

A number of postings have shown up recently regarding an Edupage article on 21-Feb-95. This article suggests that there is a security hole in "Mosaic," which could lead to destruction of a number of Web sites. edupage-02.21.95

Unfortunately, this article is somewhat inaccurate: the security weakness lies in the NCSA HTTPd server software (version 1.3) for Unix Web servers. The client software (Mosaic or otherwise) is not responsible for any security problems; in addition, this problem does not affect Macintosh Web servers like MacHTTP.

For more information, check out NCSA's Web page; there is also a link to a patch for the code and a patched pre-compiled binary version. The URL is: desc.html
