FTP服务与客户端设计FTP为一种文件传输协议服务器客户端：服务器日志在线用户程序设置统计安全服务器日志在线用户程序设置统计安全客户端连接服务器上传文件下载文件连接服务器上传文件下载文件服务器客户端erver and Client Abstract FTP is a mainstream network file transfer protocol. Design and Implementation of FTP services and clients will help in-depth understanding of network programming and FTP, and make the theoretical knowledge and practice together. In this paper, using VC + +6.0 programming tool, the FTP server and client designe are designed and implemented. The main design work is for: the design of server and client . Server-side design modules are: server logs module, online modules, procedures set module, statistics module, the security module. Server logs showing module is responsible for the various log information, online displaying is module responsible for online information, procedures setting module is responsible for the allocation of server operating parameters, statistics module is responsible for all the statistical work, security module is responsible for the management of user access privileges. Client design modules are: connect to server module, upload module, download files module. The module to connect to server is responsible for accessing servers by the information which the user enter, uploading file module is responsible for uploading the local paper to the server, downloading files module is responsible for downloading the documents to the local machine from server. Through practical application and testing, it verifys the correctness of the design of the paper.
