telenet is an useful tool to test the network connection.

E.g. if you want to test is a web server is still online you will want to try something like this

telnet notnull.ro 80

If you are on Windows 10, by default the telnet command is not available, it has to be installed/enabled, you will get a message like

‘telnet’ is not recognized as an internal or external command,
operable program or batch file.

Here are the steps to enable it

  1. Search for Command Prompt and run it as administrator , like in picture below
  2. In command prompt run next command

dism /online /Enable-Feature /FeatureName:TelnetClient

Now the telnet command should work.
