I already know there are ssh modules for Python, that's not for what I'm looking for. What I want to have is an python script to do the following:

  1. > connect to an [ input by user ] SSH host
  2. > connect using the credentials [ provided by the user ]
  3. > run command on the SSH host [ telnet to [host - input by user ]
  4. > Select menu item in the telnet session

Thanks in advance,

Best regards,

    I don't get it. You need to do SSH-related stuff in Python and you are not interested in SSH modules for Python? – tokland Feb 04 '11 at 10:14

    @Tokland, I'm looking for an example script. Not for answers like, "Fabric is a Python library and command-line tool for streamlining the use of SSH" :) – Ilias Feb 04 '11 at 10:39

Use paramiko, see http://jessenoller.com/2009/02/05/ssh-programming-with-paramiko-completely-different/ for a through example of using it.

Use paramiko or the libssh2 python bindings.

If you're actually looking for a module that lets you automate CLI interaction, there's pexpect

There are many libraries to do that.

  1. Subprocess
  2. Pexpect
  3. Paramiko (Mostly used)
  4. Fabric
  5. Exscript

You can check their documentation for the implementation.

I will refer you to:

import spur

shell = spur.SshShell(hostname="localhost", username="bob", password="password1", missing_host_key=spur.ssh.MissingHostKey.accept)
result = shell.run(["echo", "-n", "hello"])
print(result.output) # prints hello

import paramiko

hostname = 'enter_host'
username = 'enter_user'
password = 'enter_pass'

client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(hostname, username=username, password=password)

stdin, stdout, stderr = client.exec_command('cd /enter/valid/path && ls -l')

for line in stdout:
    print(line.strip('\n'))

client.close()

output:

-rw-rw-r-- 1 username username 2712 Jan 22 14:49 file_1.ini
-rw-rw-r-- 1 username username 5928 Jan 22 14:50 file_2.log
-rw-rw-r-- 1 username username 1454 Jan 14 23:31 file_3.sql
-rw-rw-r-- 1 username username  337 Jan 14 23:31 file_4.py
drwxrwxr-x 3 username username 4096 Jan 14 23:33 folder_1
drwxrwxr-x 2 username username 4096 Jan 14 23:33 folder_2
-rw-rw-r-- 1 username username 2566 Jan 21 12:38 file_5.md
-rw-rw-r-- 1 username username   63 Jan 14 23:31 file_6.txt
drwxrwxr-x 4 username username 4096 Jan 14 23:31 folder_3
drwxrwxr-x 9 username username 4096 Jan 21 12:38 folder_4
  • No libraries required
import subprocess

subprocess.Popen("ssh {user}@{host} {cmd}".format(user=user, host=host, cmd='ls -l'), shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE).communicate()

You can use the vassal package, which is exactly designed for this.

All you need is to install vassal and do

from vassal.terminal import Terminal
shell = Terminal(["ssh username@host", "cd scripts", "python foo1.py", "python foo2.py"])
shell.run()

This will run the command once every second, and you can make it run faster to change sec=0.1.
