mode <br /> The mode in which data is to be transferred via the data <br /> connection. The mode defines the data format during transfer <br /> including EOR and EOF. The transfer modes defined in FTP are <br /> described in the Section on Transmission Modes. <br /> NVT <br /> The Network Virtual Terminal as defined in the Telnet Protocol. <br /> NVFS <br /> The Network Virtual File System. A concept which defines a <br /> standard network file system with standard commands and <br /> pathname conventions. <br /> page <br /> A file may be structured as a set of independent parts called <br /> pages. FTP supports the transmission of discontinuous files as <br /> independent indexed pages. <br /> pathname <br /> Pathname is defined to be the character string which must be <br /> input to a file system by a user in order to identify a file. <br /> Pathname normally contains device and/or directory names, and <br /> file name specification. FTP does not yet specify a standard <br /> pathname convention. Each user must follow the file naming <br /> conventions of the file systems involved in the transfer. <br /> PI <br /> The protocol interpreter. The user and server sides of the <br /> protocol have distinct roles implemented in a user-PI and a <br /> server-PI. <br />Postel & Reynolds [Page 5] <br /> <br /> <br />RFC 959 October 1985 <br />File Transfer Protocol <br /> record <br /> A sequential file may be structured as a number of contiguous <br /> parts called records. Record structures are supported by FTP <br /> but a file need not have record structure. <br /> reply <br /> A reply is an acknowledgment (positive or negative) sent from <br /> server to user via the control connection in response to FTP <br /> commands. The general form of a reply is a completion code <br /> (including error codes) followed by a text string. The codes <br /> are for use by programs and the text is usually intended for <br /> human users. <br /> server-DTP <br /> The data transfer process, in its normal "active" state, <br /> establishes the data connection with the "listening" data port. <br /> It sets up parameters for transfer and storage, and transfers <br /> data on command from its PI. The DTP can be placed in a <br /> "passive" state to listen for, rather than initiate a <br /> connection on the data port. <br /> server-FTP process <br /> A process or set of processes which perform the function of <br /> file transfer in cooperation with a user-FTP process and, <br /> possibly, another server. The functions consist of a protocol <br /> interpreter (PI) and a data transfer process (DTP). <br /> server-PI <br /> The server protocol interpreter "listens" on Port L for a <br /> connection from a user-PI and establishes a control <br /> communication connection. It receives standard FTP commands <br /> from the user-PI, sends replies, and governs the server-DTP. <br /> type <br /> The data representation type used for data transfer and <br /> storage. Type implies certain transformations between the time <br /> of data storage and data transfer. The representation types <br /> defined in FTP are described in the Section on Establishing <br /> Data Connections. <br />Postel & Reynolds [Page 6] <br /> <br /> <br />RFC 959 October 1985 <br />File Transfer Protocol <br /> user <br /> A person or a process on behalf of a person wishing to obtain <br /> <br /> <br /> <br />-- <br />指點(diǎn)江山,激揚(yáng)文字,糞土當(dāng)年萬(wàn)戶(hù)侯。 <br /> <br /> <br />※ 來(lái)源:·BBS 水木清華站 smth.org·[FROM: 166.111.161.69] <br /><a href="00000013.htm">上一篇</a><a href="javascript:history.go(-1)">返回上一頁(yè)</a><a href="index.htm">回到目錄</a><a href="#top">回到頁(yè)首</a><a href="00000015.htm">下一篇</a></h1></center><center><h1>BBS 水木清華站∶精華區(qū)</h1></center></body></html>
