我无法上传文件，它挂在：
150 opening data connection for file.txt
连接似乎没问题，我运行这个脚本：
open proxyserver proxyport
user@ftp.something.com
password
cd try
bin
quote pasv
put C:\file.txt
quit
我别无选择，只能用 ctrl+c 关闭连接，然后我收到以下消息：
425 Can't open data connection.
421 Service not available, closing control connection.
filezilla 没问题，但我必须使用批处理。提前感谢您的回答。
有关此建议，请参阅以下 URL：
报价Many FTP clients do not support PASV transfers. For example, the
standard FTP.EXE built into Windows does not support this feature. The
user can still do a "quote PASV", which will tell the server to enter
PASV mode, but the client still will not work in this mode. (This is a
common problem, users enter "quote PASV" but things still don't work).
