ssh client with paramiko (python)

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()

When I try to run more then 1 command I get this error:

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

看起来是因为在while循环结束while您执行ssh.close() （因此关闭了会话）。
