A“SYN” scan, however, drops the connection when the first packet is returned from the server. This is called a “half-open” scan and used to be promoted as a way to surreptitiously scan for ports, since the application associated with that port would not receive the traffic, because th...

An application is actively accepting TCP connections, UDP datagrams or SCTP associations on this port. Finding these is often the primary goal of port scanning. Security-minded people know that each open port is an avenuefor attack. Attackers and pen-testers want to exploit the open ports, whi...
命令:nmap --sS --sU --T4 --top-ports 300 www.baidu.com 参数: -sS表示使用TCP SYN方式扫描TCP端口; -sU表示扫描UDP端口; -T4表示时间级别配置4级; –top-ports 300表示扫描最有可能开放的300个端口(TCP和UDP分别有300个端口)。 编辑 从上图中,我们看到扫描结果,在扫描的300个端口中,有298个是关闭...
