    怎樣關閉電腦不用的端口

    時間:2015-10-30 15:09:05本文內容及圖片來源于讀者投稿,如有侵權請聯系xuexila888@qq.com 廣達 我要投稿

      每一項服務都對應相應的端口,比如眾如周知的WWW服務的端口是80,smtp是25,ftp是21,win2000安裝中默認的都是這些服務開啟的。對于個人用戶來說確實沒有必要,關掉端口也就是關閉無用的服務。“控制面板”的“管理工具”中的“服務”中來配置。下面是學習啦小編為大家整理的怎樣關閉電腦不用的端口,希望大家能夠從中有所收獲!
     

      1、關閉7.9等等端口:關閉Simple TCP/IP Service,支持以下TCP/IP服務:Character Generator,Daytime, Discard, Echo, 以及 Quote of the Day。

      2、關閉80口:關掉WWW服務。在“服務”中顯示名稱為"World Wide Web Publishing Service",通過 Internet 信息服務的管理單元提供 Web 連接和管理。

      3、關掉25端口:關閉Simple Mail Transport Protocol (SMTP)服務,它提供的功能是跨網傳送電子郵件。

      4、關掉21端口:關閉FTP Publishing Service,它提供的服務是通過 Internet 信息服務的管理單元提供 FTP 連接和管理。

    怎樣關閉電腦不用的端口

      5、關掉23端口:關閉Telnet服務,它允許遠程用戶登錄到系統并且使用命令行運行控制臺程序。

      6、還有一個很重要的就是關閉server服務,此服務提供RPC支持、文件、打印以及命名管道共享。關掉它就關掉了win2k的默認共享,比如ipc$、c$、admin$等等,此服務關閉不影響您的其他操作。

      7、還有一個就是139端口,139端口是NetBIOS Session端口,用來文件和打印共享,注意的是運行samba的unix機器也開放了139端口,功能一樣。以前流光2000用來判斷對方主機類型不太準確,估計就是139端口開放既認為是NT機,現在好了。

      關閉139口聽方法是在“網絡和撥號連接”中“本地連接”中選取“Internet協議(TCP/IP)”屬性,進入“高級TCP/IP設置”“WINS設置”里面有一項“禁用TCP/IP的NETBIOS”,打勾就關閉了139端口。

      對于個人用戶來說,可以在各項服務屬性設置中設為“禁用”,以免下次重啟服務也重新啟動,端口也開放了。
