I am doing hands on in Paramiko lib. In the below code I created a shell and sent command ls. With sleep its working fine. But when I don’t use sleep it’s unable to capture output even if its just ls which happens to give output instantly on terminal. Also the order of output is very random (like how two thread’s output doesn’t follow any order.
import paramiko import time ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect('127.0.0.1', port=22, username='uname', password='pass', timeout=3) shell = ssh.invoke_shell() shell.send(b"lsn") # time.sleep(1) output = shell.recv(10000).decode("utf-8") print(output) The output is like this:

At the very least, it should show this every time –
