SSH客户端的paramiko（蟒蛇）

Question

# sshpy v1 by s0urd 
# simple ssh client 
# irc.gonullyourself.org 6667 #code 

import paramiko 
import os 

ssh = paramiko.SSHClient() 
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) 
privatekey = os.path.expanduser('/home/rabia/private') 
mkey = paramiko.RSAKey.from_private_key_file(privatekey) 
ssh.connect('78.46.172.47', port=22, username='s0urd', password=None, pkey=mkey) 

while True: 
     pick = raw_input("sshpy: ") 
     stdin, stdout, stderr = ssh.exec_command(pick) 
     print stdout.readlines() 
     ssh.close() 

当我尝试运行更多的则1个命令我得到这个错误：

AttributeError: 'NoneType' object has no attribute 'open_session'

看起来是因为在while循环你做ssh.close()结束（因此关闭会议）。
