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 - docs.paramiko.org/en/stable/api/client.html — balderman

I've tried that as well, with that: 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

No one will be able to help if you are not sharing the code. So share the code that calls paramiko. — balderman

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
