# 功能：扫描主机的22号端口是否开放并将成功的导出日志，如果有22号端口被检测到公开出去了，则导出日志，并立即发送邮件给责任人aochaunfei

    # 第一步：打开文件（文件存放了私网IP = 公网IP 22 格式），对文件的内容一行一行的读取，同时进行telnte操作
          # a.如果telnet返回值为0说明telnet成功，则公网的22号端口被公开出去，有被攻击的风险，那么将对应得 公共IP 写入到以一个时间打头的文件里面
          # b.反之则将 公网IP 写入到另外一个时间打头的文件里面作为区分

    # 此处有问题，截取出来的不是
    # os.environ[‘ip_port‘] = str(ip_port)
    #ip = str(ip_port.strip())
    ip = ip_port.split("=")[-1].strip()
    print ip
    status = commands.getstatusoutput(‘telnet $ip‘)
    if status == 0:
        ExposePort_log.write(ip_port)
    else:
        NoExposePort_log.write(ip_port)

f.close()
ExposePort_log.close()
NoExposePort_log.close()

    # 第二步：将暴露公网IP 22号端口的文件通过邮件附件的形式发送个邮箱

server.login("aochuanfei","aixocm123")  #仅smtp服务器需要验证时 

# 构造MIMEMultipart对象做为根容器
main_msg = email.MIMEMultipart.MIMEMultipart()

# 构造MIMEText对象做为邮件显示内容并附加到根容器
text_msg = email.MIMEText.MIMEText("请注意附件里的公网的22号端口已经暴露",_charset="utf-8")
main_msg.attach(text_msg)

# 构造MIMEBase对象做为文件附件内容并附加到根容器
ctype,encoding = mimetypes.guess_type(file_name)

maintype,subtype = ctype.split(‘/‘,1)
file_msg=email.MIMEImage.MIMEImage(open(file_name,‘rb‘).read(),subtype)
print ctype,encoding

## 设置附件头
basename = os.path.basename(file_name)
file_msg.add_header(‘Content-Disposition‘,‘attachment‘, filename = basename)#修改邮件头
main_msg.attach(file_msg)

# 设置根容器属性
main_msg[‘From‘] = From
main_msg[‘To‘] = To
main_msg[‘Subject‘] = "请注意！！！"
main_msg[‘Date‘] = email.Utils.formatdate( )

# 得到格式化后的完整文本

# 用smtp发送邮件
try:
    server.sendmail(From, To.split(‘,‘), fullText)
finally:
    server.quit()
