Python并行SSH -如何传递多个用户名和密码

import paramiko
from getpass import getpass

def ssh_command(hostname, username, password, command):
    # 创建SSH客户端对象
    client = paramiko.SSHClient()
    # 自动添加远程主机的SSH密钥
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    try:
        # 连接远程主机
        client.connect(hostname, username=username, password=password)
        # 执行命令
        stdin, stdout, stderr = client.exec_command(command)
        # 输出命令执行结果
        print(stdout.read().decode())
    except paramiko.AuthenticationException:
        print(f"Authentication failed for {username}@{hostname}")
    finally:
        # 关闭SSH连接
        client.close()

# 服务器列表
servers = [
    {"hostname": "server1.example.com", "username": "user1", "password": getpass("Enter password for user1: ")},
    {"hostname": "server2.example.com", "username": "user2", "password": getpass("Enter password for user2: ")},
    # 可以添加更多的服务器
]

# 执行的命令
command = "ls -l"

# 并行执行SSH命令
for server in servers:
    ssh_command(server["hostname"], server["username"], server["password"], command)
