我從家裡掃公司的主機得到的資料如下:
[root@linux /root]# nmap www.test.idv.tw
Starting nmap V. 3.00 ( www.insecure.org/nmap/ )
Interesting ports on u190-30.u61-80.giga.net.tw (61.70.190.30):
(The 1588 ports scanned but not shown below are in state: closed)
Port State Service
21/tcp open ftp
22/tcp open ssh
25/tcp open smtp
53/tcp open domain
80/tcp open http
110/tcp open pop-3
111/tcp filtered sunrpc
139/tcp filtered netbios-ssn
445/tcp filtered microsoft-ds
514/tcp filtered shell
515/tcp filtered printer
1433/tcp filtered ms-sql-s
3306/tcp open mysql
Nmap run completed -- 1 IP address (1 host up) scanned in 148 seconds
我的iptable有對外開放的port有 21.22.25.53.80.110
其它445.514.515.1433我並沒有對外開放它的壯態是filtered
這是什摸意思呢?
還有3306port我在iptable並沒有對外開放,為什摸它會是open呢?
