Research And Realization Of Remote Installation Of LAN Exclusive Software

With the development of LAN technology, software of LAN management and maintenance emerges in endlessly, but the installation of these kinds of LAN exclusive software costs much time, especially when the computers disperse in LAN. This kind of installation is completed artificially, which may bring the repetition installation or skip the installment by mistake, and is extremely easy to make mistake. Moreover there isn't any maintenance of LAN exclusive software, so it is difficult to manage the software-working situation effectively. Therefore, a solution to LAN exclusive software is urgently needed for remote installment and management. With the research of TCP/IP technology and network programming, this paper provides a more accurate, quicker solution to remote automatic installation with good effect and expansibility.The paper discusses the meaning and developing status of the system. After analyzing detailed requirement of the system, it designs system's general structure, discusses detailed design thinking and realization process of the system, implements module division and design. The object oriented modeling technology is used in the development process, which can keep the system vigorous, healthy and reusable.The system divides into four modules: on-line computer examination module, computer port scanned module, remote installation module and network control module. On-line computer examination module analyzes the realization of NetBIOS method, ARP method, ICMP method and points out the advantage, disadvantage and the application scope of each of them, provides the reliable basis for following processing. In computer port scanned module, it analyzes several kinds of common technologies of port scanned, and discusses the application of multi-thread technology and data packet captured technology in port scanned, thus enhances the system agility. Remote installation module elaborates how to carry on the IPC connection, how to realize the remote installation and the influence of the operating system edition to the installment, deals with the exception of the installation process. Network control module uses the method of firewall programming to capture local data packet, and the method of ARP spoof to control remote data packet, comprehensively detects the LAN exclusive software's situation, guarantees the integrity of the exclusive software.By using the technologies such as TCP/IP, socket, multithreading, firewall, the remote installation system of LAN exclusive software has been implemented. Recently, it is running stably in the enterprise.
