POWERSHELL TEST NET CONNECTION

From Microsoft documentation: The Test-NetConnection cmdlet displays diagnostic information for a connection. It supports ping tests, TCP tests, route tracing, and route selection diagnostics. Depending on the input parameters, the output can include the DNS lookup results, a list of IP interfaces, IPsec rules, route/source address selection results, and/or confirmation of connection establishment.

To mimic the Telnet command one can use:

1

Test-NetConnection -ComputerName <HOSTNAME OR IP> -InformationLevel "Detailed" -Port <DESTINATION PORT>

Test ping connectivity with detailed results

1

Test-NetConnection -ComputerName <HOSTNAME OR IP> -InformationLevel "Detailed"
