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 should significantly alleviate those concerns if installed correctly. 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.
Avoid Long Hierarchical Menus
If you right-click (or Control-click) on some item, such as a file in the Finder, and one of the sub-menus has many options (Open With is a frequent culprit), it may take several seconds to open, even on a fast machine, which is annoying if you did not actually want that sub-menu.
The trick is to not pull the cursor through the menu, but in a curve around it, so the cursor does not touch any menu items until lower on the list where you wanted to go.
