FTP 命令模式下 PASV OR PORT

FTP 命令模式下 PASV OR PORT

我们经常会在DOS命令模式下使用FTP的一些命令,不过,在进行Upload/Download时,经常会碰到一个命令的反馈:
use PORT or PASV first.
请问如何操作呢?
按常里,我们会根据提示,输入PASV或者PORT指令.其实这样输入是无法进行的.
使用的方法如下:
如果需要切换到PORT模式:quote PORT;
同样,如果需要PASV模式:quote PASV即可.

原文:
The FTP server wants to know whether to use a port-mode channel or passive-mode data channel. Most clients will set this up for you transparently (and generally choose passive 'cos it's newer and better). To send a command to the server you use the 'quote' command. Hence if you type:

quote PASV

then it should all work nicely. As an aside, if you type 'remotehelp' then it should show you all the commands that the server can receive - all these can be used with the 'quote' command.
