Telnet – Send GET/HEAD HTTP Request

Telnet is a tool for connecting to servers on a given port for troubleshooting connection issues.

One of the most common tasks that you can do via telnet – is connect to some web server and verify its health by checking the response code in HTTP header.

Or you can get the content of a whole web page via telnet if you need to analyze it deeper.

Cool Tip: Familiar with `telnet` or `curl`? Check a website availability from the Linux command line, like a PRO! Read more →

Below you will find the examples of sending GET and HEAD request to a web server from the command line using telnet.

Telnet – Check HTTP Response

Use the following syntax to connect to a [SERVER] on some [PORT] via telnet and request it for HTTP header of some [WEB PAGE]:

$ telnet [SERVER] [PORT]
Trying xxx.xxx.xxx.xxx...
Connected to [SERVER].
Escape character is '^]'.
HEAD [WEB PAGE] HTTP/1.1
HOST: [SERVER]
<Press ENTER>

Check the HTTP header of this website’s main page using telnet:

$ telnet www.shellhacks.com 80
Trying xxx.xxx.xxx.xxx...
Connected to www.shellhacks.com.
Escape character is '^]'.
HEAD / HTTP/1.1       
HOST: www.shellhacks.com
<Press ENTER>

Check the HTTP header of the current web page using telnet:

$ telnet www.shellhacks.com 80
Trying xxx.xxx.xxx.xxx...
Connected to www.shellhacks.com.
Escape character is '^]'.
HEAD /telnet-send-get-head-http-request HTTP/1.1
HOST: www.shellhacks.com
<Press ENTER>

Telnet – Get Web Page’s Content

 

Probably it is not enough just to receive an HTTP response code from the web server.

 

For example you may need to ensure that some particular text exists on a web page.

For this you can download the entire web page using telnet and then perform more deeper analyze of its content.
