137端口是NetBIOS Name Service，向局域网或互联网上的某台计算机的137端口发送一个请求，就可以获取该计算机的名称、注册用户名，以及是否安装主域控制器、IIS是否正在运行等信息，不过这里已经被comodo拦截了，没什么问题的，lz可以关闭137端口
你通过局域网是否要用网上邻居传输文件，如果要，就不要关闭此端口，如果不需要通过网上邻居传输文件就关闭137，138端口
服务器的UDP,TCP端口的扫描工具 - nmap (UDP扫描)
今天我新加坡的同事问我如何判别服务器的UDP的5060端口是否打开的，及对SIP协议打开端口的分析.
因 Telnet + IP + 端口号是对TCP的判断，故使用第三方软件nmap.
从 http://nmap.org 下载安装了Window7版，测试了一下感觉真不错.
Target: 填IP
Profile: Intense scan plus UDP
Nmap Output:
