網絡安全與端口詳解

作者:佚名 來源:網絡 時間:2007-01-12

按端口號可分為3大類:
(1)公認端口(Well Known
Ports):從0到1023,它們緊密綁定(binding)于一些服務。通常這些端口的通訊明確表明了某種服務的協議。例如:80端口實際上總是HTTP通訊。

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

(3)動態和/或私有端口(Dynamic and/or Private
Ports):從49152到65535。理論上,不應為服務分配這些端口。實際上,機器通常從1024起分配動態端口。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。這一方法能夠工作是因為在一些系統中“0”是無效端口,當你試圖使用一種通常的閉合端口連接它時將產生不同的結果。一種典型的掃描:使用IP地址為0.0.0.0,設置ACK位并在以太網層廣播。
