How to send carriage return over telnet?

问题

I am using Ubuntu telnet client. I am trying to send 2 lines over the telnet connection that I have made.

For example:

> telnet en.wikipedia.org 80
  GET /wiki/Main_Page http/1.1   <CR>                            // line 1
  Host: en.wikipedia.org         <CR>                            // line 2
  <CR>

where CR stands for carriage return. The problem is after typing line 1, press CR , that line will be sent over the telnet connection. I can not be able to send line 2 immediately after that.

Can somebody help?

回答1:

When you are operating in a Telnet client, sending a newline or carriage return control code to the client, will send it directly to the host.

The easiest way to do what you want would be to copy/paste the HTTP GET request from another text editor, so that the newlines are embedded in the text.

You can set the crlf option in telnet. You can do this by, during your telnet session, typing the escape character (^]), and then "toggle crlf". A perhaps cleaner way is to specify this before making the connection:

$ telnet
telnet> toggle crlf
Will send carriage returns as telnet <CR><LF>.
telnet> open mailhost smtp

Try Ctrl+Shift+Enter I tried on Mac OS Mojave Terminal.
