python的paramiko模块报错解决办法

#-*- coding:utf-8 -*-

__author__ = 'kai'

import paramiko

import sys,os

 

host = sys.argv[1]

user = 'zk'

password = '123'

 

cmd = sys.argv[2]

 

s = paramiko.SSHClient()        #绑定实例

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

s.set_missing_host_key_policy(paramiko.AutoAddPolicy())

 

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

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

 

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

 

for line in cmd_result:

        print line,

 

s.close()

主要是练习用的，执行之后报错：

#python paramkio.py localhost df

No handlers could be found for logger "paramiko.transport"

Traceback (most recent call last):

  File "paramkio.py", line 16, in <module>

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

  File "build/bdist.linux-x86_64/egg/paramiko/client.py", line 296, in connect

  File "build/bdist.linux-x86_64/egg/paramiko/transport.py", line 458, in start_client

paramiko.SSHException: Incompatible ssh peer (no acceptable kex algorithm)

产生的原因是因为安装的paramiko模块版本太低

查看当前的paramiko版本：pip freeze

lxml==3.4.2

MySQL-python==1.2.5

ndg-httpsclient==0.3.2

oauthlib==0.6.1

oneconf==0.3.7

PAM==0.4.2

paramiko==1.7.6

Pillow==2.7.0

piston-mini-client==0.7.5

pyasn1==0.1.7

pyasn1-modules==0.0.5

pycrypto==2.6.1

pycups==1.9.72

然后直接升级模块版本就行了：pip install paramiko --upgrade

 

paramiko==1.15.2
