我正在尝试开始使用Paramiko库,但是当我尝试连接以下简单程序时,库就会抛出异常:

import paramiko
ssh = paramiko.SSHClient()
ssh.connect('127.0.0.1', username='boatzart', password='mypassword')

我得到的错误是:

Traceback (most recent call last):
File "test.py", line 6, in <module>
ssh.connect('127.0.0.1')
File "build/bdist.macosx-10.7-intel/egg/paramiko/client.py", line 316, in connect
File "build/bdist.macosx-10.7-intel/egg/paramiko/client.py", line 85, in missing_host_key
paramiko.SSHException: Unknown server 127.0.0.1

无论我尝试哪种服务器都会发生这种情况

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:
