简介：普通用户执行sudo时需要输入对应密码才能运行成功。所以仅使用常规的shell命令不足以完成任务，这里推荐使用paramiko+交互式shell进行处理。
历史攻略：
Python：paramiko获取top实时数据
案例源码：ssh_client.py

import time
import paramiko
def chanel_exe_cmd(ChanelSSHOb, cmd, t=0.1):
ChanelSSHOb.send(cmd)
ChanelSSHOb.send("\n")
time.sleep(t)
resp = ChanelSSHOb.recv(9999).decode("utf8")
print("<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<")
print("Exec sshCmd: %s" % (cmd))
print("--------------------")
print("Exec Result: %s" % (resp))
print(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>\n")
return resp
def creatSShConnectOb(ip_remote, port_remote, username, password):
print('---------- start to create SSH object')
print('Remote SSH Info:\n\'ip:%s port:%d username:%s password:%s\'\n' % (
ip_remote, port_remote, username, password))
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
try:
ssh.connect(ip_remote, port_remote, username=username, password=password, timeout=60) # timeout protection
return ssh
except:
print('Warning:\nFist connect the ABC failed, now will retry!')
ssh.connect(ip_remote, port_remote, username=username, password=password, timeout=60) # timeout re-try
print('Error:\nAttempt to connect ABC failed!!! Please check the IP / port/ account / password.')
主程序源码：

from ssh_client import chanel_exe_cmd, creatSShConnectOb
def run():
ssh = creatSShConnectOb("11.12.13.14", 22, "ken", "123456")
chanelSSHOb = ssh.invoke_shell() # 建立交互式的shell
cmd = 'sudo -s'
if "password for ken" in chanel_exe_cmd(chanelSSHOb, cmd):
cmd = "123456"
chanel_exe_cmd(chanelSSHOb, cmd)
cmd = 'pwd'
chanel_exe_cmd(chanelSSHOb, cmd)
cmd = 'whoami'
chanel_exe_cmd(chanelSSHOb, cmd)
if __name__ == '__main__':
run()
执行结果：切换sudo后，whoami = root
