I'm working on an InfoSec exercise, specifically sending emails in cmd that makes use of telnet. Unfortunately, I can't start it. I'm receiving the "'telnet' is not recognized as an internal or external command,operable program or batch file." from cmd when I type telnet. Can someone please tell me on what to install and its procedures for me to access telnet command in CMD. Thanks!

I hope you are using windows 7. Telnet is disabled by default to enable it follow control panel> programs & features > In left bar select "turn windows features on or off > in list find "Telnet Client" tick it Click ok. Done!! you telnet should be working now.

Telnet is a Windows feature that needs to be enabled.

Control Panel > Programs & Features > Turn Windows features on or off > check the box at Telnet Client

You can install telnet client by using DISM command-line tool, e.g.:

dism /online /Enable-Feature /FeatureName:TelnetClient

or using pkgmgr (deprecated in favor of above):

pkgmgr /iu:"TelnetClient"

Usage

The syntax is:

telnet example.com 80

where example.com is your destination host (can be localhost for local PC) and 80 is the port number.

When you connect, to disconnect, hit Control+], then type quit command to exit.
