Send Multiple commands using Netmiko - command

Question

I am struggling to send multiple commands to multiple hosts , i am using commands input from a file:
commands.txt
sh ip int bri
sh run
sh ver
hosts.txt
router 1
router 2
router 3
I then run following
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("Enter Jumphost Password") elif (op == 2): TACACSpassword = getpass.getpass ("Enter TACACS Password") elif(in1=="c"): commandsfile = input ("Please Enter CommandsFile path as c:/example/ \n :") hostsfile = input ("Please Enter Hosts path as 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 = {'device_type': '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 ("File saved in c:\saad\saad.txt ") output += net_connect.send_config_set(cmd1) print (output) net_connect.disconnect print ("File saved in c:\saad\saad.txt ") file.write(output) file.close() continue

Place your IPs in ips.csv file in the following format...
Host
192.168.1.1
192.168.1.2
Then use the following code, usage 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
