Python Forum

Hi All,

I have written a code snippet here. Where I wanted to connect a remote network, execute my script which is present in that system and get the output of that script.

import paramiko

ssh = paramiko.SSHClient()

ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname = 'x.x.x.x', port = 22, username = 'admin', password = 'pass')
stdin, stdout, stderr = ssh.exec_command('python /home/maiya/sample.py', get_pty = True)
print(stdout.readlines())
ssh.close()

what could be the issue in above code?, as am getting an error authentication failed.

Error:
PS C:\Users\maiya\test> python connect.py
Traceback (most recent call last):

Any suggestion would really help. Thanks a lot

Try to connect with allow_agent=False perhaps. Otherwise check that you can connect the remote host without Python, perhaps from Putty in Windows.

Connection is there, however allow_agent = False helps actually.

How to run the python script over ssh?
