如果我指定端口范围并扫描开放端口，如下所示 范围，我得不到结果，即使端口（每netstat）清楚 打开并收听此范围内的网络活动：
[me@box ~]$ ./nmap --open -A --script ssl-enum-ciphers.nse,ssl-cert.nse -p [10050-65535] w.x.y.z
Starting Nmap 7.01 at 2016-01-21 16:24 CST
Service detection performed. Please report any incorrect results at http.../submit/ .
Nmap done: 1 IP address (1 host up) scanned in 0.63 seconds
见上文：没有报道！
但是，如果我扫描同一范围内的特定端口（以相同的方式），我得到了 结果我期待：
[me@box ~]$ ./nmap --open -A --script ssl-enum-ciphers.nse,ssl-cert.nse -p 10050 w.x.y.z
Starting Nmap 7.01 ( ) at 2016-01-21 16:24 CST
Nmap scan report for box-name (w.x.y.z)
Host is up (0.00010s latency).
PORT STATE SERVICE VERSION
10050/tcp open http Apache httpd
|_http-server-header: Apache
Service detection performed. Please report any incorrect results at ht.../submit/ .
Nmap done: 1 IP address (1 host up) scanned in 11.74 seconds
怎么了？为什么不在结果中报告该端口（以及其他一些端口） 从第一个命令行？除了它之外，第二个命令行是相同的 指定一个已知打开的特定端口（并且输出证明它确实是打开的）。
对我毫无意义。有什么建议？ 如果重要的话，这是nmap 7.01。
此外，我正在使用自己的特定IP地址扫描本地盒子本身 https端口已启动并正在侦听。 （不是扫描其他一些远程机器）。
答案 0 :(得分：1)
在端口列表周围使用括号表示“仅扫描服务文件中出现的端口”。 Nmap附带的nmap-services文件不包含对端口10050的引用，因此不扫描该端口。实际上，您可以使用Grepable output和-v标记来查看扫描的端口：
