使用nmap 6.45扫描服务器心脏出血漏洞(heartbleed)的具体方法(步骤)如下：
当然，你要先按好nmap，自己可以去网上google下。
在使用nmap 的过程中指定 ssl-heartbleed.nse 脚本来扫描探测，命令如下;
 [root@dabu.info ~]#nmap -sV -p 443 --script=ssl-heartbleed.nse 192.168.1.5
 或者
 [root@dabu.info ~]#nmap -sV -p 443 --script=ssl-heartbleed 192.168.1.5
 解释;其中 192.168.1.5 是要被扫描的ip，也可以换成域名假设你的服务器(vps)有心脏出血漏洞(heartbleed)漏洞，则会有出现下面的提示:
代码如下:
Nmap scan report for mediacentre (192.168.1.5)
 Host is up (0.0059s latency).

 | ssl-heartbleed:
 |VULNERABLE:
 |The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. It allows for stealing information intended to be protected by SSL/TLS encryption.
| State: VULNERABLE
 | Risk factor: High
 | Description:
 | OpenSSL versions 1.0.1 and 1.0.2-beta releases (including 1.0.1f and 1.0.2-beta1) of OpenSSL are affected by the Heartbleed bug. The bug allows for reading memory of systems protected by the vulnerable OpenSSL versions and could allow for disclosure of otherwise encrypted confidential information as well as the encryption keys themselves.

 这两行表示扫描的结果。 升级完成后，我们再次测试，就没有刚才的提示了。而是变成：
代码如下:
Nmap scan report for mediacentre (192.168.1.5)
 Host is up (0.0011s latency).
