利用Nmap扫描处事器长途桌面端口

 我常常用它来检测长途的 Windows处事器的ip地点，因为不是牢靠ip地点，该处事器的ip地点会常常变革，可是有个纪律，只在一个网段内变革，这样就给ip地点简直定带来 了利便。

1. 假如没有安装nmap，就安装

 yum install -y nmap

2. 扫描指定网段的长途桌面毗连端口

nmap -sT -p3389 218.206.112.0/24

3. 假如以为输出太多，九江服务器 东莞服务器，可以用 grep 呼吁过滤

nmap -sT -p3389 218.206.112.0/24 | grep -B2 open

下面是操纵的动静记录，备查。
