python实现端口扫描监控，宕机则发送邮件

import socket

def get_ip_status(ip,port):
    server = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    try:
        server.connect((ip,port))
        print(‘{0} port {1} is open‘.format(ip,port))
    except Exception as err:
        print(‘{0} port {1} is down‘.format(ip,port))
        send_mail(ip,port)//宕机就发送邮件
    finally:
        server.close()
        
def send_mail(ip,port):
    fromAddr = "*********@126.com"
    toAddr = "*********@126.com"
    password = "************"
    smtp_server = "smtp.126.com"
    import smtplib
    from email.mime.text import MIMEText
    msg = MIMEText("Test body")  //处理邮件文本内容
    msg[‘Subject‘] = "the {0}:{1} is down".format(ip,port)
    //msg[‘Subject‘] = ‘%s %d is down!!!‘ %(ip,port)
    server = smtplib.SMTP(smtp_server,25)
    server.login(fromAddr,password)
    server.sendmail(fromAddr,toAddr,msg.as_string())
