Selecting Controllers For Networking Environment

Selecting Controllers For Networking Environment Prof. Dr. Alaa AL-Hamami* Soukaena Hassan Hashem** Abstract: Internet is network of networks; the Internet has numerous numbers of Internet sites. Many of these sites are sensitive and protected against the intentional hostile intrusion by strong protection systems. Most of these sites used the firewall protection system to protect them although the protected sites, networks, differs in architectures, addressing, computations and another maters. This paper concentrates on implementation of a proposed protection system on any Internet site with high performance, by control and detects most of networking environment parameters. Such as ports, listening to ports, IP addresses, IP conversion, IP scanning, ping, ping listening, online/offline operations, times of synchronization, TCP/IP requirement, routing operations, Application Programming Interface (API) calls. Keywords: Internet, protection, control, detect. 1- Introduction: To contact with the proposed networking controller first we must identify the important parameters of the proposed controller. Site is a piece of land; exploited for some benefits work. Internet site may be computer, Local Area Network (LAN), or multiple LAN(s) over a piece of land such as university, collage, government agency, office, company, organization, or individual [2,1]. Ports usually ports predefined (0 to 255) to well known applications (i.e., FTP and E-mail). Undefined ports are provided as well, allowing operating system to define their own ports when necessary [3]. For example TELNET connection has number 23 [4]. * Department of Computer Science of Al-Rafidian University College. 1

IP Addressing Each 32-bit IP address is divided into two parts: a prefix and suffix; the two-level hierarchy is designed to make routing efficient. An IP address is a 32-bit long and is commonly expressed as a four decimal number ranging from 0 to 255, with each number separated by a dot [5]. The address prefix identifies the physical network to which the computer attached, while the suffix identifies an individual computer on network [6]. Ping is an Internet Control Message Protocol (ICMP) echo request and replay packets, where ICMP is a protocol used by IP when sends an error message and ICMP uses IP to transport messages [6]. Online/ Offline operations detect the computation of specified host was online or offline. Routing When connecting networks together to form the Internet, the most important protocol is called, not surprising Internet protocol (IP). The Internet protocol is responsible for getting packets of information moved from one network to another, via process called routing. The IP protocol depends 32-bit addressed that uniquely identify each computer (called host) and network. Application programming Interface The interface an application uses when it interacts with transport protocol software is known as an Application Programming Interface (API), it is a bare-bones set of functions provided by the operating system, also is a specific method prescribed by a computer operating system so that a programmer writing an application program can make request of the operating system. An API can be contrasted with an interactive user interface or a command interface as an interface to an operating system. So it represent interface between an application program and the communication protocols in an operating system [6]. 2- The Proposed System Controllers: The proposed system controllers contained in a main menu. This part is the basic level to implement the proposed protection system, the main menu contains all the controllers. It has ten controllers on the right side and other tens on the left side, as shown in figure (1). In addition there are two menu controllers bars in the top of the main menu has the following fields. FILE which contain only Exiting option, View which contain the setting controller and tool bars, TOOLS which contain all the controllers with their specific keys, HELP contain all the information related with the proposed system and the addresses of the site developed the proposed system. The bottom bar contains the product's copyright, IP address of the computer, and the host name of the computer. As shown in figure (2). 2

Figure (2) The main menu with menu bars at the top and bottom. 2.1- Bandwidth Monitor Controller menu: This menu detect the most important physical parameter, bandwidth, which determine rate of data transmitting ( sent & received) in kilobyte per second. Estimate both the speed for upload and download. By this controller the system regulates the sent and received packets by the direct and dial up connections. See figure (3). 3

Figure (3) The bandwidth monitor menu. 2.2- IP Address Scanner Controller menu: This menu present the start address for scanning as the address of the computer installed on it, and the end address is the last address scanned on the network. The range of the scanned addresses determined by the class of IP address, for example the start IP address is 169.254.121.189 and the class was C then the end address is 169.254.121.255. This controller response to detect all nodes related with the network and mentions their host name if the user want that. There are two buttons in the bottom of the menu the first named Begin Scan response to activate the scanning operation ( through scanning operation the name of the button changed to Stop Scan if the user want to end the scan before it complete) and after the scanning complete would display a message detect the numbers of the nodes related with it. The second button named Close response to close the menu. See figure (4). Figure (4) display the IP scanner when IP scanner operation activated and detected. 2.3- IP Calculator Controller menu: This menu detect the IP address of the computer installed on it, the subnet mask related with the IP address, and the network identification connected to it this computer, see figure (5). This controller is a tool for administrator control, it check if the IP address and subnet mask they are suitable with the network or not. 4

This menu has five buttons. The button named Compute Now response to the following operations: Calculate binary information for the IP address, subnet mask, and network ID. Calculate networking information represented by detect the IP Address Class, Address Type, and last ask if the IP address suitable with the host and give the reason. Calculate subnetting information represented by detect the numbers of the subnetworks, numbers of the host, and last the range. Calculate the network ID and the broadcast ID. The second button named Reset response to repeat the work on the menu from beginning. The third Default Mask detected according the IP address if the IP address was class C then the default mask is 255.255.255.0. The fourth button named Save To File save all the information in the IP calculation menu to file. The five button Close response to close the IP calculation menu. In the proposed system this menu gives all the information related to the host connected to a network.

Exit the controller and then return to windows desktop. 3- Conclusions: 13

The study shows that, to protect an Internet site by any proposed protection system at first we must have powerful knowledge about the site environment. By using the proposed controller system. The site administrators would detect numbers of nodes in the site, the type of the addressing and all the information related with it. Also the open ports, the statistically of transmission protocols, TCP/IP configuration for each node, routing information, information about any site the administrators want to communicate with it and another important parameters. All that would simplify the implementation of the proposed protection systems on any site. 4- References: 1- IDG S 3D Visual series, Internet and World Wide Web Simplified, Maran Graphics, Ins,1995. 2- Halsall.F., Data Communication,Computer Networks and Open System, Fourth Edition, Addision-wesley Publishing Company Inc., 1996. 3- Russell.T., Telecommunication Protocols, Second Edition, Mc- Graw Hill Companies,Inc.,2000. 4- Buchanan.W., Advanced Data Communications and Networks, First Edition,Chapman,Hall,1997. 5- Held.G., Understanding Data Communication, Fifth Edition, Prentice-Hall, 1998. 6- Comer.D.E., Computer Network and Internets with Internet Application,Third Edition, Prentice-Hall, Inc., 2001. 14
