Paramiko: Parallel SSH Command Execution

Execute the same commands across multiple remote servers simultaneously using Python’s Paramiko library and multithreading.

Setup and Connection

Use paramiko for SSH connections and threading for parallel execution. The script handles key authentication and sets the host key policy automatically.

$ pip install paramiko

import time
import paramiko
import threading

# Configuration
uname = input("Username: ") or "root"
_ENTER = "\n".encode("utf-8")

ssh_client = paramiko.SSHClient()
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

private_key_path = input("Private Key Path: ")  # add your private key path
private_key = paramiko.RSAKey.from_private_key_file(private_key_path)

list_ip = [
    # Example IP list (Current: 1 server)
    "159.223.xxx.yyy",
    # Uncomment and add more IPs here for parallel execution
    # "www.xxx.yyy.zzz",
]
