Timeout/Timed-out exceptions #1596
Comments
|
This looks like a bug: for command in commands:
print('## Output of ' + command)
connection.send_config_set(commands)
print(connection.send_command(command))What is in |
|
username test password cisc0 |
|
Okay, get rid of this:
And then just send the configuration commands all at once as a list instead of using a for-loop using send_config_set. |
|
So this is what I have for my script. `#!/usr/bin/env python from future import absolute_import, division, print_function import json #signal.signal(signal.SIGPIPE, signal.SIG_DFL) # IOError: Broken pipe if len(sys.argv) < 3: #netmiko_exceptions = (netmiko.ssh_exception.NetMikoTimeoutException, netmiko.ssh_exception.NetMikoAuthenticationException)username, password = tools.get_credentials() with open(sys.argv[1]) as cmd_file: with open(sys.argv[2]) as dev_file: for device in devices: If this is correct, I still get the Timeout exceptions. |

Can you fix your markdown... |

I got rid of the exceptions. #!/usr/bin/env python
from __future__ import absolute_import, division, print_function
import json
import netmiko
import tools
import signal
import sys
#signal.signal(signal.SIGPIPE, signal.SIG_DFL) # IOError: Broken pipe
signal.signal(signal.SIGINT, signal.SIG_DFL) # KeyboardInterrupt: Ctrl-C
if len(sys.argv) < 3:
print('Usage: cmdrunner.py commands.txt devices.json')
exit()
username, password = tools.get_credentials()
with open(sys.argv[1]) as cmd_file:
commands = cmd_file.readlines()
with open(sys.argv[2]) as dev_file:
devices = json.load(dev_file)
for device in devices:
device['username'] = username
device['password'] = password
try:
print('-' * 79)
print('Connecting to device:', device['ip'])
connection = netmiko.ConnectHandler(**device)
connection.send_config_set(commands)
print()
connection.disconnect()
except netmiko_exceptions as e:
print('Failed to ', device['ip'], e) |

I get these exceptions, Traceback (most recent call last): During handling of the above exception, another exception occurred: Traceback (most recent call last): During handling of the above exception, another exception occurred: Traceback (most recent call last): I am using this script: #!/usr/bin/env python

net_connect = Netmiko(**my_device)
cfg_commands = ["username test password cisc0"]
output = net_connect.send_config_set(cfg_commands)
print(output)
net_connect.disconnect() |

What does Netmiko logging show if you enable it for that last code? |
|
DEBUG:paramiko.transport:starting thread (client mode): 0x3512dd8 Switch> Switch> DEBUG:netmiko:write_channel: b'terminal length 0\n' Switch> Switch> Switch> Switch> Switch> DEBUG:netmiko:_read_channel_expect read_data: Switch> |
|
You need to call .enable(). You also need to pass in a "secret" argument in "my_device". net_connect = Netmiko(**my_device)
net_connect.enable()
cfg_commands = ["username test password cisc0"]
output = net_connect.send_config_set(cfg_commands)
print(output) |
|
That work! Thank you for your help! I am curious about reverting back by sending no username... I tried but got the same exceptions. Do you want me to open another issue? |
|
I think removing a username in Cisco IOS has extra prompts (i.e. it prompts you if you want to do this). You will need to handle that in a special way. |

Understood. After looking at some examples, this is my code: #!/usr/bin/env python
from __future__ import print_function, unicode_literals
from netmiko import Netmiko
from getpass import getpass
import logging
logging.basicConfig(filename='send_no_config.log', level=logging.DEBUG)
logger = logging.getLogger("netmiko")
my_device = {
"host": "x.x.x.x",
"username": "user",
"password": getpass(),
"secret": "secret",
"device_type": "cisco_ios",
}
net_connect = Netmiko(**my_device)
net_connect.enable()
command = "no username test"
output = net_connect.send_config_set(command)
if "confirm" in output:
output += net .send_command_timing("\n")
print(output)
net_connect.disconnect()` |

Yes, it looks like your code is not properly handling this extra prompting: So it is failing. Here is an example of handling prompting: |
This worked for me.. thanks |
I am trying to run config commands to a Cisco switch and keep getting the below error. The script, tools, etc is modified by me using Greg Mueller. Is there something that I am missing?
