login and add user with pexepect - python

Salut,

Am de facut un script in python care sa se logheze pe mai multe servere si sa creeze useri de linux..dar mereu exista un DAR.. am o lista de ip uri si una de username si passwords.

Incerc sa adaug variabilele $username si $password in "child.sendline($username or $password) dar nu functioneaza ). Ma puteti ajuta cu o concatenare daca exista asa ceva?

#!/bin/env python
import pexpect
username = "peter"
password = "tgztgztgz"
#login
child = pexpect.spawn ('ssh [email protected]')
child.expect ('.*password:')
child.sendline ('vagrant')
child.expect ('.*64:')

#root login
child.sendline ('sudo su')
child.expect ('vagrant#')

#adding user
child.sendline ('useradd "$username"')
child.expect ('vagrant#')
#create password
child.sendline ('passwd "$username"')
child.expect ('password:')
child.sendline ('"$password"')
child.expect ('password:')
child.sendline ('"$passw0rd"')
child.expect ('vagrant#')

Am aflat gata :

#!/bin/env python
import pexpect
username = "peter"
password = "tgztgztgz"
adduser = "useradd " + username
change_password = "passwd " + username
check = 'cat /etc/group | grep %s' % username
#login
child = pexpect.spawn ('ssh [email protected]')
child.expect ('.*password:')
child.sendline ('vagrant')
child.expect ('.*64:')

#root login
child.sendline ('sudo su')
child.expect ('vagrant#')

#adding user
child.sendline(adduser)
child.expect ('vagrant#')
#create password
child.sendline (change_password)
child.expect ('password:')
child.sendline (password)
child.expect ('password:')
child.sendline (password)
child.expect ('vagrant#')
#listing
child.sendline (check)
child.expect ('vagrant#')
print child.before

Multumesc pentru ajutor!!
