怎么才能让 Proxy 不被扫描到?

iambuku

nmap -A -T4 *.*.*.*

Starting nmap 3.70 ( http://www.insecure.org/nmap/ ) at 2006-08-23 09:30 CST
Interesting ports on *.*.*.*:
(The 1654 ports scanned but not shown below are in state: closed)
PORT     STATE SERVICE    VERSION
21/tcp   open  ftp        vsFTPd 2.0.1
22/tcp   open  ssh        OpenSSH 3.9p1 (protocol 1.99)
80/tcp   open  http       Apache httpd 1.3.34 ((Unix) PHP/4.4.2)
111/tcp  open  rpcbind    2 (rpc #100000)
631/tcp  open  ipp        CUPS 1.1
9999/tcp open  http-proxy Squid webproxy 2.5.STABLE13


怎么才能不返回http-proxy Squid webproxy 2.5.STABLE13 这样的结果呢?
