How to exit telnet session via command line using azure devops

Question

I am trying to test connectivity from source to a FTP server on port 22 using azure devops commandline tool in pipelines

Command for testing: telnet TestSFTP02 22

How do I make sure the telnet connectivity is closed after running this command via the command line?

Answer 1

You will need to kill the telnet process. For example like this:

(timeout /T 5 > nul && taskkill /f /im telnet.exe > nul) | telnet TestSFTP02 22

Or use more powerful scripting language, like PowerShell.
