基于Python实现的ssh兼sftp客户端
实现ssh客户端兼ftp客户端：实现远程连接，执行linux命令，上传下载文件
Win7 64位
Python 3.3.4
paramiko 1.15.2
下载地址：
https://pypi.python.org/pypi/paramiko/1.15.2
https://pan.baidu.com/s/1i4SJ1CL
cryptography-1.0-cp34-none-win_amd64.whl
(如果paramiko可以正常安装完，则不需要安装该类库)
下载地址：
https://pypi.python.org/pypi/cryptography/1.0

安装好后，找到nt.py(本例中路径为：
Lib\site-packages\pycrypto-2.6.1-py3.4-win-amd64.egg\Crypto\Random\OSRNG\nt.py),修改
import winrandom
为
from Crypto.Random.OSRNG import winrandom
如下
#import winrandom
from Crypto.Random.OSRNG import winrandom
以解决ImportError: No module named 'winrandom'错误
VS2010
因操作系统而异，可能需要安装VS2010，以解决包依赖问题
