我需要连接到能够使用lftp成功连接的FTPS服务器.但是,当我尝试使用Python ftplib.FTP_TLS时,它会超时,堆栈跟踪显示它正在等待服务器发送欢迎消息等.有谁知道问题是什么以及如何克服？我想知道是否需要在服务器端进行某些操作,但是lftp客户端如何正常工作.任何帮助是极大的赞赏.
这是堆栈跟踪:
ftp = ftplib.FTP_TLS()
ftp.connect(cfg.HOST, cfg.PORT, timeout=60)
File "C:\Users\username\Softwares\Python27\lib\ftplib.py", line 135, in connect
self.welcome = self.getresp()
File "C:\Users\username\Softwares\Python27\lib\ftplib.py", line 210, in getresp
resp = self.getmultiline()
File "C:\Users\username\Softwares\Python27\lib\ftplib.py", line 196, in getmultiline
line = self.getline()
File "C:\Users\username\Softwares\Python27\lib\ftplib.py", line 183, in getline
line = self.file.readline()
File "C:\Users\username\Softwares\Python27\lib\socket.py", line 447, in readline
data = self._sock.recv(self._rbufsize)
socket.timeout: timed out
使用lftp成功登录到同一个ftps服务器:
$ lftp
lftp :~> open ftps://ip_address:990
lftp ip_address:~> set ftps:initial-prot P
lftp ip_address:~> login ftps_user_id ftps_user_passwd
lftp sftp_user_id@ip_address:~> ls
ls: Fatal error: …所以,我正在尝试连接到ftp服务器以获取目录列表和下载文件.但是prot_p()函数之后的第一个命令引发了异常 - 从日志中产生这些错误:
*get* '150 Here comes the directory listing.\r\n'
*resp* '150 Here comes the directory listing.'
*get* '522 SSL connection failed; session reuse required: see require_ssl_reuse
option in vsftpd.conf man page\r\n'
*resp* '522 SSL connection failed; session reuse required: see require_ssl_reuse

File "C:\Python27\lib\ftplib.py", line 725, in retrlines
return self.voidresp()
File "C:\Python27\lib\ftplib.py", line …我尝试连接到仅支持TLS 1.2使用Python 3.4.1的FTP服务器
我的代码:
import ftplib
import ssl
ftps = ftplib.FTP_TLS()
ftps.ssl_version = ssl.PROTOCOL_TLSv1_2
print (ftps.connect('108.61.166.122',31000))
print(ftps.login('test','test123'))
ftps.prot_p()
print (ftps.retrlines('LIST'))
客户端出错:

服务器端出错:
