ftplib。error\u perm:553无法创建文件。(Python 2.4.4)

我正在向我正在FTPing的用户的主目录写入内容,因此权限不应该是一个问题。FTP在FileZilla中工作。

local_enable=YES 改变

在 Debian4公司

>>> f = ftplib.FTP('address', 'user', 'password')
>>> f.cwd('/home/user/some/dir/')
'250 Directory successfully changed.'
>>> myfile = '/full/path/of/file.txt'
>>> o = open(myfile, 'rb')
>>> f.storbinary('STOR ' + myfile, o)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/lib/python2.4/ftplib.py", line 415, in storbinary
    conn = self.transfercmd(cmd)
  File "/usr/lib/python2.4/ftplib.py", line 345, in transfercmd
    return self.ntransfercmd(cmd, rest)[0]
  File "/usr/lib/python2.4/ftplib.py", line 327, in ntransfercmd
    resp = self.sendcmd(cmd)
  File "/usr/lib/python2.4/ftplib.py", line 241, in sendcmd
    return self.getresp()
  File "/usr/lib/python2.4/ftplib.py", line 216, in getresp
    raise error_perm, resp
ftplib.error_perm: 553 Could not create file.

知道它为什么失败吗?
