Open Door Slams Network Doors -- Open Door Networks has released a public beta of DoorStop, a software-based firewall for individual Macintosh servers. Unlike expensive hardware solutions, DoorStop operates only on the Macintosh on which it is installed, providing flexible blocking of TCP services. You can block any TCP connection from any address or range of addresses, block access to all TCP services on the server, block accesses to particular IP addresses on a multihomed server, and keep a log of all denied and allowed accesses. DoorStop should be of special interest to anyone running Open Door's ShareWay IP, which provides AppleShare-over-IP services to Macs running Personal File Sharing. As we commented in "Share and Share IP Alike" in TidBITS-436, ShareWay IP creates some security issues - DoorStop can significantly alleviate those concerns. DoorStop requires a PowerPC-based Mac, Mac OS 8.1, and Open Transport 1.3 or later. Pricing has yet to be set, and version 1.0b1, which expires 01-Oct-98, is a 680K download. [ACE]
Avoid Simple Typos
If, like me, you find yourself typing 2911 in place of 2011 entirely too often, you can have Mac OS X (either Lion or Snow Leopard) fix such typos for you automatically. Just open the Language & Text pane of System Preferences, click the Text button at the top, and then add a text substitution by clicking the + button underneath the list. It won't work everywhere (for that you'll want a utility like Smile's TextExpander), but it should work in applications like Pages and TextEdit, and in Save dialog boxes.
