网络安全-nmap 扫描结果处理

Question

用 nmap 扫描本地，发现如下内容：

Starting Nmap 6.25 ( http://nmap.org ) at 2013-03-05 11:00 CST
Nmap scan report for localhost (127.0.0.1)
Host is up (0.00045s latency).
Other addresses for localhost (not scanned): 127.0.0.1
rDNS record for 127.0.0.1: localhost.localdomain
Not shown: 994 closed ports
PORT     STATE SERVICE
22/tcp   open  ssh
5555/tcp open  freeciv
8086/tcp open  d-s-n
8087/tcp open  simplifymedia
8088/tcp open  radan-http
8600/tcp open  asterix

Answer 1

可以通过netstat -antlp来对比看是哪个进程在用这些端口；如果要禁止，直接通过iptables，只允许22端口开放即可。具体命令，百度一下。
