Question

我正在努力向多个主机发送多个命令，我正在使用从文件输入的命令：

commands.txt中

sh ip int bri
sh run
sh ver

HOSTS.TXT

router 1
router 2
router 3

然后我运行以下

来自 future 来自netmiko import的import print_函数ConnectHandler ##对于SSH导入重新导入getpass而True：#create loop for whole program username = input（＆＃34;输入用户名＆＃34;）jumphostpassword = getpass.getpass（＆＃34;输入Jumphost密码＆＃34;）elif（op == 2）：TACACSpassword = getpass.getpass（＆＃34;输入TACACS密码＆＃34;）elif（in1 ==＆＃34; c＆＃34;）：commandsfile = input（＆＃34;请输入CommandsFile路径为c：/ example / \ n：＆＃34;）hostsfile = input（＆＃34;请输入主机路径为c：/ example / \ n：＆＃34;）#hosts = open（（hostsfile），＆＃34; r＆＃34;）hosts = [主机的主机（hosts.strip（）用于open（hosts文件）中的主机）如果主机]对于host1中的host1：open（host1 +＆＃34; .txt＆＃34;，＆＃34; w＆＃34;）as file：commands1 = open（（commandsfile），＆＃ 34; r +＆＃34;）jumphost = {＆＃39; device_type＆＃39;：＆＃39; linux＆＃39;＆＃39; ip＆＃39;：＆＃39; 172.27.200.26＆＃39; ，＆＃39;用户名＆＃39; :(用户名），＆＃39;密码＆＃39; :( jumphostpassword）} net_connect = ConnectHandler（** jumphost）output = net_connect.send_command（＆＃34; ssh＆＃34; + str（host1））print（输出）else：output = net_connect.send_command（TACACSpassword）print（output）output = net_connect.send_command（＆＃34; term leng 0＆＃34;）print（output）cmd1 = [cmd1 for cmd1 in（对于cmd1 in open（commandsfile）中的cmd1（）cmd1）如果命令1中的cmd1为cmd1]：print（＆＃34;文件保存在c：\ saad \ saad.txt＆＃34;）output + = net_connect .send_config_set（CMD1） print（输出）net_connect.disconnect print（＆＃34;文件保存在c：\ saad \ saad.txt＆＃34;）file.write（输出）file.close（）继续

Answer 1

将IP以以下格式放置在ips.csv文件中...

Host
192.168.1.1
192.168.1.2

然后使用以下代码，用法python code.py -c ips.csv

#!/usr/bin/python

import getpass
import re
import csv
import paramiko
import netmiko
from argparse import ArgumentParser
from netmiko import ConnectHandler

if __name__ == '__main__':
    parser = ArgumentParser(description='Arguments:')
    parser.add_argument('-c', '--csv', required=True, action='store',
                        help='Location of CSV file of IPs')


args = parser.parse_args()

ssh_username = 'yoursshusername'


ssh_password = 'yoursshpassword'

with open(args.csv, 'r') as file:
    reader = csv.DictReader(file)
    for device_row in reader:
        try:
            ssh_session = ConnectHandler(device_type='cisco_ios',
                    ip=device_row['Host'],
                    username=ssh_username, password=ssh_password)
            print '********* {0} *********'.format(device_row['Host'
                    ])

        # Specify your commands here, you can add more commands just follow the same syntax
             print ssh_session.send_command('show running-config | i hostname')
        # Specify exceptions here 
        except paramiko.AuthenticationException:
    print ('{0}'.format(device_row['Host']),"Authenticaiton Problem!")
            pass

使用Netmiko
