端口基础常识大全 端口可分为3大类： 1） 公认端口（Well Known Ports）：从0到1023，它们紧密绑定于一些服务。通常这些端口的通讯明确表明了某种服务的协议。例如：80端口实际上总是HTTP通讯。 2） 注册端口（Registered Ports）：从1024到49151。它们松散地绑定于一些服务。也就是说有许多服务绑定于这些端口，这些端口同样用于许多其它目的。例如：许多系统处理动态端口从1024左右开始。 3） 动态和/或私有端口（Dynamic and/or Private Ports）：从49152到65535。理论上，不应为服务分配这些端口。实际上，机器通常从1024起分配动态端口。但也有例外：SUN的RPC端口从32768开始。 本节讲述通常TCP/UDP端口扫描在防火墙记录中的信息。记住：并不存在所谓ICMP端口。如果你对解读ICMP数据感兴趣，请参看本文的其它部分。-port basis of common sense Daquan ports can be divided into three broad categories : a) recognized ports (Well Known Ports) : 0-1023, which closely bundled with some of these services. These ports are usually clear communication of a service agreement. For example : 80-port virtually always HTTP communications. 2) Registered port (Registered Ports) : from 1,024 to 49,151. They loosely bundled with some of these services. That is to say there are many services bundled with these ports for the same used for many other purposes. For example : Many systems dynamic port from around 1024. 3) Dyn
