Hi There,
I'm trying to use fabric library to control subprocesson on linux device. I've prepared a piece of code, which intention is to log as a root user.
I can't use "sudo" method because that is not existing on the system that i want to control. Also logging directly as "root" is impossible. My idea is to log as a "admin" user and then use "su" command to switch to "root" user.
Code:
from fabric import Connection
from invoke import Responder
sudopass = Responder(pattern=r'Password:', response='adminPassword\n')
with Connection('192.168.0.106', user="admin", port=22, connect_kwargs={"password": "admin"}) as dss:
command = "uname -s"
print("Response on {} is: {}".format(command, dss.run(command)))
command = "whoami"
print("Response on {} is: {}".format(command, dss.run(command)))
command = "su"
print("Response on {} is after executing su command: {}".format(command,
dss.run(command, pty=True, watchers=[sudopass])))
command = "whoami"
print("Response on {} is: {}".format(command, dss.run(command)))
print("Script end")
Output:
Linux
Response on uname -s is: Command exited with status 0.
=== stdout ===
Linux
(no stderr)
dssadmin
Response on whoami is: Command exited with status 0.
=== stdout ===
dssadmin
(no stderr)
Password:
/home/dssadmin #
As you can see script got stuck after sending "su" command. Any ideas how to solve that?
I'm using:
Python 3.7
Fabric 2.4.0
Thanks in advance
