FTP ASCII 上传失效 近期在进行AIX到Linux迁移，发现从windows终端ftp时，客户端设置ASCII传输模式, 服务端并不能自动转换换行符号,脚本出现^M,需要手工删除。 Linux环境为RedHat7.3+vsftpd(3.0.2),vsftpd.conf中ascii_download_enable/ascii_upload_enable 注释掉了,未开启. RFC959中的ASCII TYPE 3.1.1.1. ASCII TYPE This is the default type and must be accepted by all FTP implementations. It is intended primarily for the transfer of text files, except when both hosts would find the EBCDIC type more convenient. The sender converts the data from an internal character representation to the standard 8-bit NVT-ASCII representation (see the Telnet specification). The receiver will convert the data from the standard form to his own internal form. In accordance with the NVT standard, the <CRLF> sequence should be used where necessary to denote the end of a line of text. (See the discussion of file structure at the end of the Section on Data Representation and Storage.) Using the standard NVT-ASCII representation means that data must be interpreted as 8-bit bytes. 使用ASCII模式进行ftp传输时， 会把发送端本地NewLine编码， 转为NVT-ASCII格式（ ）， 接收端收到后，再转为本地NewLine编码。 ...
