Python: Log on to a server, run a command, and store the output in a text file.

Do you need to go to a server everytime to see something, like a log file, or to create daily report ( Like me !! ). This is the end of all your miseries. 

1. You need to install paramiko for this:

https://pypi.python.org/pypi/paramiko

2. alert.txt is the name of the file where the output will be saved. This will be create in same folder as the script.

import os
import sys
import paramiko
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('192.168.123.128', username='root', password='superlazy')
stdin, stdout, stderr = ssh.exec_command("tail -20 /home/alert.log")
sys.stdout = open('alert.txt', 'w')
type(stdin)
print stdout.readlines()
sys.stdout.close()
ssh.close()
