      網(wǎng)絡(luò)端口全解

      網(wǎng)絡(luò)端口全解

        按端口號(hào)可分為3大類:

        (1)公認(rèn)端口(Well Known Ports):從0到1023,它們緊密綁定(binding)于一些服務(wù)。通常這些端口的通訊明確表明了某種服務(wù)的協(xié)議。例如:80端口實(shí)際上總是HTTP通訊。

        (2)注冊(cè)端口(Registered Ports):從1024到49151。它們松散地綁定于一些服務(wù)。也就是說(shuō)有許多服務(wù)綁定于這些端口,這些端口同樣用于許多其它目的。例如:許多系統(tǒng)處理動(dòng)態(tài)端口從1024左右開始。

        (3)動(dòng)態(tài)和/或私有端口(Dynamic and/or Private Ports):從49152到65535。理論上,不應(yīng)為服務(wù)分配這些端口。實(shí)際上,機(jī)器通常從1024起分配動(dòng)態(tài)端口。但也有例外:SUN的RPC端口從32768開始。

        0 通常用于分析操作系統(tǒng)。這一方法能夠工作是因?yàn)樵谝恍┫到y(tǒng)中“0”是無(wú)效端口,當(dāng)你試圖使用一種通常的閉合端口連接它時(shí)將產(chǎn)生不同的結(jié)果。一種典型的掃描:使用IP地址為0.0.0.0,設(shè)置ACK位并在以太網(wǎng)層廣播。
