DoorStop 1.0 Released -- Open Door Networks has released DoorStop 1.0, a software-based firewall that promises to improve security on Macintosh-based Internet servers, particularly those providing AppleShare-over-IP services via Open Door's ShareWay IP. Operating only on the Macintosh on which it is installed, DoorStop enables you to block or grant access to specific TCP services - see "Open Door Slams Network Doors" in TidBITS-444 for more details. DoorStop requires a PowerPC-based Macintosh, Mac OS 8.1, and Open Transport 1.3 or later. Single copies of DoorStop cost $299 or $199 for education customers; other volume and site licenses are available. You can download a 680K evaluation version. [ACE]
Copy Disk Image as Folder
When you open a .dmg file, a disk image is mounted. You are then generally supposed to copy the contents of that disk image to your hard drive (to your Desktop, your Applications folder, or wherever). But what if you want to copy the whole disk image, including all its contents, as a folder? Hold the Option key, and drag the "proxy icon" in the title bar of the disk image window to the destination in the Finder.
