测试系统扫描的功能

1）在192.168.88.55上安装rh9，内核版本为2.4.20-8，下载http://download.insecure.org/nmap/dist/nmap-3.30-1.i386.rpm。执行rpm -Uvh nmap-3.30-1.i386.rpm安装。

2）在服务器端执行：

nmap –sP 192.168.88.50

结果：

Starting nmap 3.30 ( http://www.insecure.org/nmap/ ) at 2003-09-16 11:18 CST

Note: Host seems down. If it is really up, but blocking our ping probes, try -P0

Nmap run completed -- 1 IP address (0 hosts up) scanned in 12.046 seconds

 

执行：nmap –sT 192.168.88.50

结果：
