Alan B. Oppenheimer graduated from M.I.T in 1983, writing his thesis on a new
networking technology called Ethernet. Upon arriving at Apple Computer, he became
part of a team working to create the network for a new computer called the Macintosh.
Alan was responsible for many of AppleTalk's protocols, in both the Macintosh
and the LaserWriter printer. Alan also worked on AppleShare, the Apple Internet
Router and Apple Remote Access, and is a co-author of the book Inside AppleTalk,
the definitive reference on the AppleTalk network system.
Alan left Apple to found Open Door Networks, Inc. in January 1995. In addition
to providing Macintosh-based Internet access and Web hosting, Alan helped establish
Open Door as a Macintosh Internet utilities company, focusing on AppleTalk-to-IP
migration and Internet security. Alan and Open Door created such products as
ShareWay IP (used by Apple to implement Mac OS 9's TCP/IP File Sharing), the
DoorStop Personal Firewall (licensed by Symantec for use in their Norton Personal
Firewall) and the Who's There? Firewall Advisor.
Alan lives in beautiful Ashland Oregon with his beautiful wife Priscilla and
their cat Kingsford.
