每台主机都有不同的端口和密码，您可以使用嵌套字典的方式来存储主机、端口和密码的信息。以下是更新后的示例代码：

pip install paramiko

import paramiko

def test_ssh_connection(ip, port, username, password):
    try:
        ssh = paramiko.SSHClient()
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        ssh.connect(ip, port=port, username=username, password=password, timeout=5)
        print(f"Successfully connected to {ip}:{port}")
        ssh.close()
    except paramiko.AuthenticationException:
        print(f"Authentication failed for {ip}:{port}")
    except paramiko.SSHException as e:
        print(f"SSH connection error for {ip}:{port}: {str(e)}")
    except Exception as e:
        print(f"Error connecting to {ip}:{port}: {str(e)}")

# 请在这里提供主机信息，每个主机信息以(IP地址, 端口, 密码)的形式表示
hosts = [
    ("192.168.1.1", 2222, "password1"),
    ("192.168.1.2", 2223, "password2"),
    ("192.168.1.3", 2224, "password3")
]

username = "your_username"  # 替换为实际的用户名

for host in hosts:
    ip, port, password = host
    test_ssh_connection(ip, port, username, password)
