Netmiko SSH Timeout

I am having issues SSH to a Cisco IOS device. I have tested manual SSH directly from box that I am running the script from with NO issues.

Thanks for any assistance.

#!/usr/bin/env python

from netmiko import ConnectHandler

with open('commands_file') as f:
    commands_list = f.read().splitlines()

with open('devices_file') as f:
    devices_list = f.read().splitlines()

for devices in devices_list:
    print 'Connecting to device" ' + devices
    ip_address_of_device = devices_list
    ios_device = {
        'device_type': 'cisco_ios',
        'ip': 'ip_address_of_device',
        'username': '',
        'password': '',
        'secret': ''
    }

    net_connect = ConnectHandler(**ios_device)
    output = net_connect.send_config_set(commands_list)
    print output

    net_connect = ConnectHandler(**ios_device)
    output = net_connect.send_command_expect('test aaa group tacacs+ readonly Temp1234 legacy')
    print output

I don’t think the way you are creating your array of devices works the way you intend…

import time
devices = '''
          192.168.1.100
          192.168.1.86
          192.168.17.1
          '''.strip().splitlines()

print(devices)
for device in devices:
        print('~'*79)
        print('Connection to Device -',device,'-')
        time.sleep(1)

results in output that looks like the following…

['192.168.1.100', '          192.168.1.86', '          192.168.17.1']
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Connection to Device - 192.168.1.100 -
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Connection to Device -           192.168.1.86 -
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Connection to Device -           192.168.17.1 -

notice the leading spaces on all but the first “host”, that is why you are getting the underlying socket.gaierror: [Errno 11001] getaddrinfo failed error, and subsequent netmiko.ssh_exception.NetMikoTimeoutException: Connection to device

Json Error While Loading file… Hi I am getting below error when loading file using Json

Traceback (most recent call last): File “C:\MOBILY\004_Personal\Amazon-Interview\SCRIPT\List-IP-jsonload.py”, line 11, in <module> devices = json.load(dev_file) File “C:\ProgramData\Anaconda3\lib\json_init_.py”, line 296, in load parse_constant=parse_constant, object_pairs_hook=object_pairs_hook, **kw) File “C:\ProgramData\Anaconda3\lib\json_init_.py”, line 348, in loads return _default_decoder.decode(s) File “C:\ProgramData\Anaconda3\lib\json\decoder.py”, line 337, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File “C:\ProgramData\Anaconda3\lib\json\decoder.py”, line 353, in raw_decode obj, end = self.scan_once(s, idx) json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 4 (char 3)

Can you please advise me what went wrong …

HI dBitch,

thanks for pointing our the error. I have fixed it. The issue was few unnecessary wide spaced before the array. The below code work fine.

Again Thanks a lot. It was a syntax error.

devices = ‘’’ 10.153.4.56 10.153.4.57 10.153.4.50 10.153.4.51 10.153.4.52 ‘’'.strip().splitlines()

#devices = [‘10.153.4.56’, ‘10.153.4.57’, ‘10.153.4.50’, ‘10.153.4.51’, ‘10.153.4.52’] for device in devices: #try: print(‘~’*79) print(‘Connection to Device’, device)

(base) C:\Users\kirups>python C:\MOBILY\004_Personal\Amazon-Interview\SCRIPT\List-IP-test.py

Connection to Device 10.153.4.56

Connection to Device 10.153.4.57

Connection to Device 10.153.4.50
