SSH with Python Script

Question

I'm new at python and i'm trying to create a Python script to SSH (Throw putty), to my server and to execute 'sudo reboot' command (as you probbebly know , sudo is a requied a pass).

as I search here and google, I found this: Python script for SSH through PuTTY

At Putty download page there is 'Plink' I've downloaded that (few version tbh) and it's just open it and close it , not installing something or showme anything. just closing the window soon it's opened. What am I missing? also tried to do that with Paramiko:

import paramiko

host = "myip"
port = 22
username = "myusername"
password = "mypassword"

command = "sudo reboot"

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(host, port, username, password)

stdin, stdout, stderr = ssh.exec_command(command)
ssh.close()

Thank you.

why use putty? use paramiko - http://docs.paramiko.org/en/stable/api/client.html — balderman, Sep 26 '21 at 13:42
I've tried that as well, with that: https://www.kite.com/python/answers/how-to-ssh-using-paramiko-in-python i've installed it and it's not really working and I don't know how to add a command to execute. — Meitar Edri, Sep 26 '21 at 13:45
No one will be able to help if you are not sharing the code. So share the code that calls paramiko. — balderman, Sep 26 '21 at 13:47
what happen when you run the code? Please attache all error details (if there is one) — balderman, Sep 26 '21 at 13:56
can you communicate with this server (as human) via putty or other ssh client? — balderman, Sep 26 '21 at 17:12
Yes , Via Putty I can log in and execute by myself the command, if this what you are asking. — Meitar Edri, Sep 26 '21 at 17:17

If you have problems with executing commands, you need to read their (error) output to see any error messages.

Also your current code does not even complete the command. And reading the command output is the actually easiest way in Paramiko to actually get your command completed.

See Wait to finish command executed with Python Paramiko
For another common problem, see Some Unix commands fail with "<command> not found", when executed using Python Paramiko exec_command
