InterCon Systems Corporation (a Virginia Corporation) was founded in April 1988 by Kurt D. Baumann and Mikki Barry to produce software to connect Macintosh computers in environments that were not Macintosh-exclusive. At the time, there was no real concept of the Internet and there was still a question of whether the TCP/IP protocols or OSI protocols would be adopted widely. Over the next 9 years, the company grew from three employees to over 100 and sold software in the US, Europe and Japan.
In June 1995, InterCon was acquired by PSINet and continued to sell and maintain its suite of TCP/IP software. [1]
In February 1996, PSINet merged InterCon with Software Ventures (another Macintosh communication software company). [2]
In February 1997, InterCon's engineering group and its products were sold to Ascend Communications. [3]
In 1988, InterCon was pursuing two product lines, TCP/Connect (based originally on NCSA Telnet), and an email product. Unfortunately, the licensing for the email product fell through in negotiations, so it was never sold, and InterCon would have to wait a few more years (until TCP/Connect II) before it could provide email to customers.
TCP/Connect was InterCon's flagship product. Launched at Macworld Conference & Expo in August 1988, the product provided the same features as NCSA Telnet, with commercial technical support as its only significant added benefit. This was to change rapidly over the next few months, and by October of that year, InterCon was showing the product at the first InterOp Expo with new features including a graphical FTP Client (one of the first on the Macintosh) and IBM 3270 emulation.
Over the next few years, InterCon added more terminal emulation and file transfer capabilities to the product, but no other major protocols until the product was replaced with a significant rewrite: TCP/Connect II.
TCP/Connect II was to remain InterCon's flagship product from 1990 until 1995. Although TCP/Connect was primarily a terminal emulation and file transfer program, TCP/Connect II branched out into a full-fledged internet suite. At introduction, it featured email and network news reader support along with additional terminal emulations in addition to the already-popular IBM 3270, and DEC VT-240 emulations.
Over the next 5 years, the product evolved quickly and kept or set the pace for many advanced features, including embedded graphics and multimedia content in email; advanced email automation, filtering, and highlighting; a high-speed web browser; a gopher client; and many minor features and protocols.
After the introduction of InterCon's web browser in TCP/Connect II, AOL licensed the browser in 1995 for use with their dial-up networking services. In order to separate the browser from the rest of the suite, it was dubbed WebShark.
tcpCONNECT4 (renamed from TCP/Connect II and with additional features) was a "do-everything suite of TCP/IP applications for Internet or intranet use" [4] that was released in 1996 and had few changes before the company's sale to Ascend Communications.
NFS/Share was InterCon's second most popular product and provided high-performance access to file servers using the NFS protocol. NFS was used widely in educational environments because it was the key file sharing system for Sun Microsystems's line of UNIX servers. NFS/Share's adoption mirrored that popularity, finding a home in many educational institutions and pre-press environments.
NFS/Share used many techniques to increase performance and provide a smooth experience for users, as such providing some of the best performance in the marketplace.
In 1995, InterCon decided to more directly approach the consumer market with a series of "Shark" branded products; NetShark, WebShark, and MailShark. The products were directly derived from the source code for TCP/Connect II (or 4 at the time) and was missing the Terminal Emulation technology.
NetShark [5] (and the derivative MailShark) was an internet suite product based on TCP/Connect but including only email and web clients. The slimmed-down version was aimed at consumers, but never really became a popular offering.
MailShark was created but never sold. It contained only the email portions of TCP/Connect.
WebShark contained only the web browser portion of TCP/Connect. WebShark was licensed by AOL for use with their Macintosh clients to provide access to the web. [6] [7] A rebranded WebShark similarly shipped as Apple's eWorld Web Browser. [8]
InterSLIP [9] and InterPPP [10] were software packages that enabled Macintosh users to communicate over TCP/IP using dial-up lines without having to use an embedded TCP/IP stack. These products worked with Apple's MacTCP.
InterPrint was a printing product designed to allow Macintoshes to print to PostScript printers connected over TCP/IP networks. Mostly used in corporate and prepress environments, the product integrated directly into Apple's printer architecture.
InterServer Publisher [11] was a web, FTP, and gopher server package designed to run in the background on a Macintosh.
Planet X was an X Window System client for Macintosh that allowed you to send the screen from your Macintosh as a window to any X Window System server. The product was developed by a third party and was marketed and sold by InterCon starting in 1991. [12]
WatchTower was the first SNMP Network Monitoring System developed for the Macintosh computer [13] Developed by GBP Software (now ClueTrust) and published and sold by InterCon starting in 1990, WatchTower was the first product of its kind on the Macintosh. Although it was never a high volume product (not surprising at a retail price of $2,495), it did represent the first monitor (and agent) for the Macintosh.
When the initial research for IPv6 was being done, InterCon participated by creating an implementation of the SIPP protocol running on the Macintosh as part of an experimental version of TCP/Connect II. Although SIPP wasn't adopted, this early effort confirmed the interest of Internet software vendors in creating IPv6-capable software. [14]
In 1992, InterCon saw the need to expand commercial internet services in Japan in order to bolster its position in the TCP/IP market there. To do this, the company created a Japanese subsidiary, IIKK and partnered with AT&T JENS (a subsidiary of AT&T) to create the first commercial internet service providers in the country. [15] [16]
IIKK's initial POP was in Joi Ito's bathroom. [16] IIKK's first offices were in an old karaoke bar in Myogadani. [17]
PSINet purchased IIKK and it became the core of PSINet Japan. [16]
AppleTalk is a discontinued proprietary suite of networking protocols developed by Apple Computer for their Macintosh computers. AppleTalk includes a number of features that allow local area networks to be connected with no prior setup or the need for a centralized router or server of any sort. Connected AppleTalk-equipped systems automatically assign addresses, update the distributed namespace, and configure any required inter-networking routing.
HTTP is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access, for example by a mouse click or by tapping the screen in a web browser.
Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems (Sun) in 1984, allowing a user on a client computer to access files over a computer network much like local storage is accessed. NFS, like many other protocols, builds on the Open Network Computing Remote Procedure Call system. NFS is an open IETF standard defined in a Request for Comments (RFC), allowing anyone to implement the protocol.
The File Transfer Protocol (FTP) is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built on a client–server model architecture using separate control and data connections between the client and the server. FTP users may authenticate themselves with a plain-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. For secure transmission that protects the username and password, and encrypts the content, FTP is often secured with SSL/TLS (FTPS) or replaced with SSH File Transfer Protocol (SFTP).
SOCKS is an Internet protocol that exchanges network packets between a client and server through a proxy server. SOCKS5 optionally provides authentication so only authorized users may access a server. Practically, a SOCKS server proxies TCP connections to an arbitrary IP address, and provides a means for UDP packets to be forwarded. A SOCKS server accepts incoming client connection on TCP port 1080, as defined in RFC 1928.
The Apple Filing Protocol (AFP), formerly AppleTalk Filing Protocol, is a proprietary network protocol, and part of the Apple File Service (AFS), that offers file services for macOS, classic Mac OS, and Apple II computers. In OS X 10.8 Mountain Lion and earlier, AFP was the primary protocol for file services. Starting with OS X 10.9 Mavericks, Server Message Block (SMB) was made the primary file sharing protocol, with the ability to run an AFP server removed later in macOS 11 Big Sur. AFP supports Unicode file names, POSIX and access-control list permissions, resource forks, named extended attributes, and advanced file locking.
AppleShare is a discontinued product from Apple Computer which implements various network services. Its main purpose is to act as a file server, using the AFP protocol. Other network services implemented in later versions of AppleShare included a print server using the Printer Access Protocol (PAP), web server, electronic mail server, and SMB / CIFS server to support file sharing to Microsoft Windows clients.
Internet security is a branch of computer security. It encompasses the Internet, browser security, web site security, and network security as it applies to other applications or operating systems as a whole. Its objective is to establish rules and measures to use against attacks over the Internet. The Internet is an inherently insecure channel for information exchange, with high risk of intrusion or fraud, such as phishing, online viruses, trojans, ransomware and worms.
BlitzMail was an e-mail system used at Dartmouth College in Hanover, New Hampshire, United States. It was one of the earliest e-mail server/client packages. Use of BlitzMail ended in 2011, in favor of a Microsoft suite of email/online collaboration programs, but students still use the term "blitz" rather than "email."
FirstClass is a client–server groupware, email, online conferencing, voice and fax services, and bulletin-board system for Windows, macOS, and Linux. FirstClass's primary markets are the higher-education and K-12 education sectors, including four of the top ten largest school districts in the United States.
cc:Mail is a discontinued store-and-forward LAN-based email system originally developed on Microsoft's MS-DOS platform by Concentric Systems, Inc. in the 1980s. The company, founded by Robert Plummer, Hubert Lipinski, and Michael Palmer, later changed its name to PCC Systems, Inc., and then to cc:Mail, Inc. At the height of its popularity, cc:Mail had about 14 million users, and won various awards for being the top email software package of the mid-1990s.
Amiga software is computer software engineered to run on the Amiga personal computer. Amiga software covers many applications, including productivity, digital art, games, commercial, freeware and hobbyist products. The market was active in the late 1980s and early 1990s but then dwindled. Most Amiga products were originally created directly for the Amiga computer, and were not ported from other platforms.
In computer networking, a port or port number is a number assigned to uniquely identify a connection endpoint and to direct data to a specific service. At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service. A port at the software level is identified for each transport protocol and address combination by the port number assigned to it. The most common transport protocols that use port numbers are the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP); those port numbers are 16-bit unsigned numbers.
NCSA Telnet is an implementation of the Telnet protocol developed at the National Center for Supercomputing Applications of the University of Illinois at Urbana-Champaign, first released in 1986 and continuously developed until 1995. The initial implementation ran under Mac OS and Microsoft MS-DOS, and provided basic DEC VT102 terminal emulation with support for multiple simultaneous connections and an FTP client. NCSA Telnet was the first implementation of telnet for the Macintosh or PC that provided the ability to connect to multiple hosts simultaneously.
The GatorBox is a LocalTalk-to-Ethernet bridge, a router used on Macintosh-based networks to allow AppleTalk communications between clients on LocalTalk and Ethernet physical networks. The GatorSystem software also allowed TCP/IP and DECnet protocols to be carried to LocalTalk-equipped clients via tunneling, providing them with access to these normally Ethernet-only systems. The GatorBox was designed and manufactured by Cayman Systems, Inc.
Barry Appelman is recognized as being the father of the "buddy list" and AOL instant messenger. Companies had been using crude forms of Instant messaging within their own networks for over forty years, but the idea of presence, i.e. who is logged on at any given time, was non existent. It was not until Appelman, and his colleagues at the Thomas Watson Research Center, first began to write programs on the mainframe system letting each other know when they were actually online, that modern day Instant Messaging was born.
TOPS is a peer-to-peer LAN-based file sharing system best known in its Macintosh implementation, but also available for DOS and able to interoperate with Unix's NFS. Originally written by Centram Systems West, the company was purchased by Sun Microsystems as part of Sun's development of the NFS ecosystem. The Centram company was renamed to TOPS after its acquisition by Sun. Sales of TOPS dried up after the introduction of System 7, which featured a similar file sharing system built-in, and Sun spun off their NFS developments to Sitka.
NetManage Inc. was a software company based in Cupertino, California, founded in 1990 by Zvi Alon, an Israeli engineer. The company's development centre was located at the MATAM technology park, in Haifa, Israel. In June 2008 the company was acquired by Micro Focus International, a British company based in Newbury, Berkshire.
The following outline is provided as an overview of and topical guide to software:
