I Telnet www.baidu.com 80 first, and then into the editing interface, enter the GET/HTTP/1.1, but it does not respond to my 10 minutes

Then I Telnet the same local area network (LAN) another host: Telnet 192.168.1.106 80, about 10 seconds show "unable to connect to the specified host"

Then I Telnet: Telnet 192.168.1.103 80, shows the bad request, but the time display is wrong

So I have the following problems: Telnet a host, is need each other host also opens the Telnet service can? The firewall is also can prevent the Telnet connections?

CodePudding user response:

Telnet the default port number is 23, if behind the Telnet IP without the port number that you need each other open Telnet service, if Telnet to other ports such as port 80, there would be no need to start the Telnet service,
Baidu's servers must have done some test, don't think your link is through the normal browser, such as quickly disconnect your links, or do not respond to you,
