ProxyCommandFailure:'An operation was attempted on something that is not a socket'

[budikols]

from error log:

File "C:\Users\d717090\AppData\Local\Continuum\anaconda3\lib\site-packages\paramiko\proxy.py", line 106, in recv raise ProxyCommandFailure(' '.join(self.cmd), e.strerror)

ProxyCommandFailure: ('ssh -xaW 172.16.180.100:22 jumphost', 'An operation was attempted on something that is not a socket')

trying to use netmiko with a jump host to ssh to 172.16.180.100 but receive this error above.

I have the same issue. It looks like it is Windows related. The same code works well under Linux.

import os
import sys
import paramiko

def test_client(host_name):
    conf = paramiko.SSHConfig()
    conf.parse(open(os.path.expanduser('~/.ssh/config')))
    host = conf.lookup(host_name)
    client = paramiko.SSHClient()
    client.load_system_host_keys()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

    client.connect(
        host['hostname'], username='cisco',
        password='cisco',
        sock=paramiko.ProxyCommand(host.get('proxycommand'))
    )
    stdin, stdout, stderr = client.exec_command('sh users')
    print(stdout.read())

if __name__ == '__main__':
    test_client('10.255.0.6')

When I run a similar command directly from cmd/powershell it works fine

PS C:\Users\pehruby\Documents\Vagrant\netbuntu\ansible-cpoj\netmiko-test> ssh -o ProxyCommand='ssh -o StrictHostKeyCheck
ing=no jumphost nc 10.255.0.6 22' cisco@10.255.0.6
