Using Paramiko Module in Python to Execute Remote Bash Commands

Paramiko is a python implementation of the sshv2 protocol.

Paramiko to execute Remote Commands:

We will use paramiko module in python to execute a command on our remote server.

Client side will be referenced as (side-a) and Server side will be referenced as (side-b)

Getting the Dependencies:

Install Paramiko via pip on side-a:

1
$ pip install paramiko --user

Using Paramiko in our Code:

Our Python Code:

1

import paramiko

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname='192.168.10.10', username='ubuntu', key_filename='/home/ubuntu/.ssh/mykey.pem')

stdin, stdout, stderr = ssh.exec_command('lsb_release -a')

for line in stdout.read().splitlines():
    print(line)

ssh.close()

Execute our Command Remotely:

Now we will attempt to establish the ssh connection from side-a, then run lsb_release -a on our remote server, side-b:

$ python execute.py
