2. Background Art
In modern computing environments, it is commonplace to employ multiple computers or workstations linked together in a network to communicate between, and share data with, network users. A network also may include resources, such as printers, modems, file servers, etc., and may also include services, such as electronic mail.
A network can be a small system that is physically connected by cables (a local area network or “LAN”), or several separate networks can be connected together to form a larger network (a wide area network or “WAN”). Other types of networks include the internet, tel-com networks, the World Wide Web, intranets, extranets, wireless networks, and other networks over which electronic, digital, and/or analog data may be communicated. Individual computers often use various ports to physically connect to a network. For example, if you need to dial into a network using the phone lines and a modem, the modem port may be utilized. Other ports that may be used include a Printer Port, Ethernet, Infrared, and Remote Access.
To enable the computers on a network to communicate with each other, a set of standardized rules for exchanging the information between the computers, referred to as a “protocol”, is utilized. Protocols generally specify the data format, timing, sequencing, and error checking of data transmissions. Numerous protocols are used in the networking environment. For example, transmission control protocol/internet protocols (“TCP/IP”) are the protocols used on the internet and on many multiplatform networks, and AppleTalk is the network protocol built into every Macintosh computer.
To enable individual computers to utilize a specific protocol, numerous computer settings, including the settings for the desired protocol, must be properly configured. Several software applications for controlling the settings, referred to here as “utilities” may be utilized to control the configuration and modification of a protocol to enable network capabilities. For example, in a Macintosh environment, the following “control panel” user interface utilities may be utilized to configure a computer for various types of network access: AppleTalk, TCP/IP, OT/PPP (Open Transport/Point-to-Point), Infrared, Dial Assist, and Modem. Further, the information and data relating to each protocol are stored independently from other protocols in individual files. These files are accessible to one user at a time. If two users desire to access the configuration file, the first user to open the file with the information is permitted access and the second user is denied access. Some prior art methods permit multiple users to read a file at the same time. However, these methods do not provide any protection for those users should the file be modified by another user while they are reading it.
In some situations, if one of the protocols is configured in a certain manner, one of the other protocols does not operate. For example, if two configurations or devices try and use the same non-sharable port, the user may not be allowed to use the desired port until the conflicting device is deactivated (e.g., a printer can't be activated if it shares the same port as “modem settings”). To deactivate the conflicting device, the user has to search numerous control panels to locate the conflicting device and deactivate or delete the conflicting configuration by adjusting the settings. Thus, the use of an individual control panel for each protocol forces the user to make adjustments and modifications in numerous control panels in order to properly configure the computer. For example, if a user desires to enable multiple networking protocols (e.g., one TCP/IP protocol with a static IP address (IP addresses are discussed below), one TCP/IP protocol with a dynamic IP address, and one AppleTalk protocol), numerous control panels for each protocol must be accessed and configured properly. In addition, if a user desires to connect to the internet, but has a protocol other than TCP/IP active (e.g., AppleTalk), the connection cannot be processed. The user may have to deactivate the active protocol (e.g., AppleTalk) using that protocol's control panel, and then activate the TCP/IP protocol using the TCP/IP control panel.
To route messages and communicate between computers using a TCP/IP protocol, each individual computer must be identified with a unique identifier or address. The unique identifier is referred to as an internet address or Internet Protocol (IP) address. An individual computer can be assigned a static IP address that does not change. An individual computer can also maintain a dynamic IP address such that whenever it connects to the network, the computer is assigned an IP address. In this manner, each time the individual computer connects to the network, a different IP address may be assigned to the computer.
It is often beyond the scope of the user's knowledge to configure a networking protocol. For example, an employee that solely performs word processing is not likely to have the knowledge to configure his/her computer for network access and operation. Thus, it is desirable for a network administrator to be able to configure a user's computer from the administrator's or another's computer (referred to as “remote configuration”).
To enable a computer to execute a sequence of instructions or commands, a computer program is utilized. One type of computer program that provides for the automation of a task or a series of tasks is called a script. A script can be used to perform simple tasks such as a file back-up, or more complex tasks such as adding capability to a program or presentation. A scripting language is used to create a script.
Two common methods are utilized in scripting languages: (1) Event Scripting; and (2) Semantic Scripting. Event scripting consists of mimicking a user's actions and events as they are performed in a user interface. For example, copying the user's actions entailed in moving a mouse over a screen location containing a checkbox for activating sound and depressing the mouse button. Semantic scripting consists of function specific commands that perform specific actions. For example, the execution of a command to activate sound. In the Macintosh environment, one type of semantic scripting language that is often utilized is called AppleScript.
To enable network configuration, one prior art method referred to as “Location Manager”) allows users to assign specific settings to a “location” for a variety of capabilities including networking, printers, time zone, file sharing, sound, and frequently used applications. Once a location is set up, a user can select that location and the computer system recognizes the user's preferences for that environment. For example, a home location and an office location may be set up for the various printers and networks available at the user's home and office. However, it is not possible for a network administrator to remotely configure a computer or adjust network settings.
Another prior art method used to configure a network referred to as “NetInfo” provides for a centralized database that contains the available configurations. When a user wants to configure his/her computer for network capabilities, the user accesses the centralized database to determine what options are av
