python 获取linux 网卡IP地址和mac地址

在Python中，你可以使用内置模块如`ipifaces`、`netifaces`或者第三方模块`psutil`来获取Linux系统的网卡IP地址和MAC地址。这里以`netifaces`为例，这是一个广泛用于网络配置信息查询的库：

import netifaces

def get_ip_address_and_mac(interface_name='eth0'):
    try:
        # 获取指定网卡的信息
        ifi = netifaces.ifaddresses(interface_name)
        
        # 对于IPv4地址
        ip_address =ifi[netifaces.AF_INET][0]['addr']
        
        # 对于MAC地址（通常在IFADDRS层）
        mac_address = ifi[netifaces.AF_LINK][0]['addr']
        
        return ip_address, mac_address
    except Exception as e:
        print(f"Failed to get IP and MAC address for {interface_name}: {e}")
        return None, None

# 使用示例
ip, mac = get_ip_address_and_mac()
if ip and mac:
    print(f"Interface {interface_name} has IP address: {ip}, MAC address: {mac}")
else:
    print("No valid network interface found.")
