How to make a sudo command using Paramiko

Question

I am having some problems with commands that have sudo using paramiko
f.ex sudo apt-get update

here is my code:

try:
    import paramiko
except:
    try:
        import paramiko
    except:
        print "There was an error with the paramiko module"
cmd = "sudo apt-get update"
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
try:
    ssh.connect("ip",username="lexel",password="password")
    print "succesfully conected"
except:
    print "There was an Error conecting"
stdin, stdout, stderr = ssh.exec_command(cmd)
stdin.write('password\n')
stdin.flush()
print stderr.readlines()
print stdout.readlines()

This is a quick code. I know that I need to add sys.exit(1) and all that but this is just to demostration

I was having the same problem, and I fix with this:

In your sudo file, just add this:

Defaults:your_username !requiretty

or remove Defaults requiretty.

Also make sure your user have permission to run the command with sudo.

Fabric has sudo command. It uses Paramico for ssh connections. Your code would be:

#fabfile.py
from fabric.api import run, sudo

def update():
    """Run `sudo apt-get update`.

    lorem ipsum
    """
    sudo("apt-get update")

def hostname():
    """Run `hostname`"""
    run("hostname")

Usage:

$ fab update -H example.com
[example.com] Executing task 'update'
[example.com] sudo: apt-get update
...snip...
[example.com] out: Reading package lists... Done
[example.com] out: 

Done.
Disconnecting from example.com... done.

$ fab --display update
Displaying detailed information for task 'update':

    Run `sudo apt-get update`.

        lorem ipsum

$ fab --list
Available commands:

    hostname  Run `hostname`
    update    Run `sudo apt-get update`.

From the docs:

In addition to use via the fab tool, Fabric’s components may be imported into other Python code, providing a Pythonic interface to the SSH protocol suite at a higher level than that provided by e.g. Paramiko (which Fabric itself leverages.)
