Python使用paramiko库远程安全连接SSH

 #!/usr/bin/python

 #ssh

 import paramiko

 host='127.0.0.1'

 user = 'whl'

 password = ''

 s = paramiko.SSHClient()                                 # 绑定实例

 s.load_system_host_keys()                                # 加载本地HOST主机文件

 s.set_missing_host_key_policy(paramiko.AutoAddPolicy())  # 允许连接不在know_hosts文件中的主机

 s.connect(host,22,user,password,timeout=5)               # 连接远程主机

 while True:

         cmd=raw_input('cmd:')

         stdin,stdout,stderr = s.exec_command(cmd)        # 执行命令

         cmd_result = stdout.read(),stderr.read()         # 读取命令结果
