在Unix系统中,FTP文件传输是其最基本的应用层服务之一,由TCP/IP的文件传输协议(File TransferProtocol,FTP)支持,该协议允许某一计算机上的用户从另外一台计算机获取义件,也允许把文件发送给另外一台计算机,并保证文件传输的可靠性,而FTP的安全性则主要通过要求用户给山自己在另外一台计算机上的用户账号与口令来完成。本文主要通过一个具体的应用实例,简要介绍如何利用FTP实现Unix系统间文件的自动传输。 笔者单位图书馆有两台Unix服务器,操作系统为SCOUnix Release 3.2V4.2,应用软件为采用INFORMIX-4GL(V2.10)所开发的一套图书馆计算机管理集成系统,系统中有两个数据库,即图书数据库与报刊数据库,有关文件分别保存在/usr/lsd/lsd/_tssjk/tssjk.dbs与/usr/lsd/lsd/_bksjk/bksjk,dbs两个目录中。两台服务器通过TCP/IP协议实现互
In Unix systems, FTP file transfer is one of the most basic application layer services supported by TCP / IP File Transfer Protocol (FTP), which allows users on one computer to get from another computer It also allows the file to be sent to another computer and ensures the reliability of the file transfer. The security of FTP is mainly achieved by asking the user to give him a user account and password on another computer. This paper mainly through a specific application examples, a brief introduction on how to use FTP to achieve the automatic transmission of files between Unix systems. The author library has two Unix servers, the operating system for SCOUnix Release 3.2V4.2, application software for the use of INFORMIX-4GL (V2.10) developed a library computer integrated management system, the system has two databases, That is, the book database and newspaper database, the relevant documents were stored in / usr / lsd / lsd /_tssjk / tssjk.dbs and / usr / lsd / lsd / _bksjk / bksjk, dbs two directories. Two servers through TCP / IP protocol to achieve each other
