paramiko.exec_command()未执行，并返回“在CLI中找到额外的参数". [英] paramiko.exec_command() not executing and returns "Extra params found in CLI"

问题描述

我正在尝试使用Paramiko SSH服务器并执行命令.但是paramiko.exec_command()返回一个错误.为什么会这样?

I am trying to ssh a server using Paramiko and execute a command. But the paramiko.exec_command() returns with an error.Why is this happening?

这是我的Python脚本:

This is my Python script:

import paramiko

ssh = paramiko.SSHClient()
ssh.load_system_host_keys()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('10.126.141.132', username='usrm', password='passwd')

stdin, stdout, stderr = ssh.exec_command("show chassis")

print(stdout.readlines())

ssh.close()

执行后返回此消息:

['在CLI中找到额外的参数，不支持此操作，退出CLI会话:\ n']

['Extra params found in CLI, this is not supported, exiting the CLI session:\n']

我在Windows上将Python 3.5.2 :: Anaconda 4.1.1(64位)与Paramiko一起使用.

I am using Python 3.5.2 :: Anaconda 4.1.1 (64-bit) with Paramiko on Windows.

我已经手动尝试过命令，并且可以正常工作.

I have tried the commands manually and it is working.

推荐答案

基于您的最新评论:

我安装了Cygwin终端，并使用以下命令对服务器进行SSH ...它出现了Extra params错误.我执行的命令:ssh usrm@10.126.141.132 "show chassis"，输出:No entry for terminal type "dumb"; using dumb terminal settings. Extra params found in CLI, this is not supported, exiting the CLI session:

I installed a Cygwin Terminal and SSH'd the server with the command...it came up with the Extra params error. Command I executed: ssh usrm@10.126.141.132 "show chassis", Output: No entry for terminal type "dumb"; using dumb terminal settings. Extra params found in CLI, this is not supported, exiting the CLI session:

这听起来像不允许SSH服务器上的usrm帐户的登录外壳以非交互方式运行命令.要解决该问题，您必须像这样使用invoke_shell():

it sounds like the usrm account's login shell on the SSH server is not allowed to run commands in the non-interactive way. To solve the problem you have to use invoke_shell() like this:

chan = ssh.invoke_shell()
chan.sendall('show chassis\r')
s = chan.recv(4096)
print s
