Paramiko SFTP密钥和用户名/密码 - "哎呀,未处理的类型3"

Question

我正在尝试通过SFTP连接到Python的远程服务器(使用Paramiko)来自动检索文件.

系统版本:操作系统:Mac OS X Lion Python:2.7.1 Paramiko:1.7.7.2

我最小的例子:

key_file = '/absolute/path/to/.ssh/id_rsa_key'  # NOT .pub
key_passphrase = 'id_rsa_key_passphrase'

host = 'ftp.test.com'
port = 22
username = 'my_ftp_username'
password = 'my_ftp_password'

# SSH Key
my_key = paramiko.RSAKey.from_private_key_file(key_file, password=key_passphrase)

# SFTP Connection
transport = paramiko.Transport((host, port))
transport.connect(username=username, password=password, pkey=my_key)
sftp = paramiko.SFTPClient.from_transport(transport)

# Print something
print sftp.listdir()

# Close connections
sftp.close()
transport.close()

以上生成以下日志输出:

有谁知道日志中的"哎呀,未处理的类型3"是什么意思？这似乎是整个事情崩溃的时候.或者,如果有人看到我在代码中做了非常错误的事情也会有所帮助.

您同时使用密码和密钥对服务器进行身份验证，这看起来像是冲突。尝试使用Transport.auth_publickey方法进行连接。如果失败，文档说使用该transport.get_exception函数来收集更多详细信息。

编辑：

据此，多因素身份验证意味着同时使用密码和密钥。因此，您应该能够使用该auth_publickey函数，然后使用auth_password方法进入。

或者，如果您有足够的访问权限，则可以将 ftp 设置调整为仅需要密钥身份验证。

您是否尝试过使用 ftp 客户端（例如filezilla ）登录？
