【问题描述】：

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

sh ip int bri
sh run
sh ver

hosts.txt

router 1
router 2
router 3

然后我运行以下

from future import print_function from netmiko import ConnectHandler ##For SSH import re import getpass while True: #create loop for whole program username = input ("Enter Username") jumphostpassword = getpass.getpass( "输入 Jumphost 密码") elif (op == 2): TACACSpassword = getpass.getpass ("输入 TACACS 密码") elif(in1=="c"): commandsfile = input ("请输入 CommandsFile 路径为 c:/example / \n :") hostsfile = input ("请输入主机路径为 c:/example/ \n :") # hosts = open((hostsfile) , "r") hosts = [hosts for hosts in (hosts.strip () for hosts in open(hostsfile)) if hosts] for host1 in hosts: with open (host1+".txt","w") as file: commands1 = open( (commandsfile), "r+") jumphost = {'设备类型': 'linux','ip': '172.27.200.26', 'username': (username),'password': (jumphostpassword)} net_connect = ConnectHandler(**jumphost) output = net_connect.send_command("ssh" + str(host1)) print (output) else: output = net_connect.send_command(TACACSpassword) print (output) output = net_connect.send_command("term leng 0") print (output) cmd1 = [cmd1 for cmd1 in (cmd1.strip () for cmd1 in open(commandsfile)) if cmd1] for cmd1 in commands1: print ("保存在 c:\saad\saad.txt 中的文件 ") output += net_connect.send_config_set(cmd1) print (output) net_connect.disconnect print ("保存在 c:\saad\saad.txt 中的文件") 文件。写（输出）file.close（）继续

【解决方案1】：

按照以下格式将您的 IP 放入 ips.csv 文件中...

Host
192.168.1.1
192.168.1.2

然后使用如下代码，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
