  1. The script should read from a file the list of hosts and ports to check.

    Example:

    server-1.dev.internal:443

    server-2.prod.internal:25

    For each line, the script should check TCP network connectivity between the server it's running on and that host:port combination and, in case it fails, find out the reason.

    Possible results for a check:

    - Success.

    - DNS record does not exist. (cannot resolve hostname)

    - Service not running (remote host is not listening on that port)

    - Connection rejected (remote host is listening on that port but network connection is rejected)

    - Timeout (remote host is listening on that port but network connection is timing out)

    Script's output will consist on a list of checks, results and the time it took for each one of them.

    Example:

    server-1.dev.internal:443 | Success | 3.4s

    server-2.prod.internal:25 | Service not running | 0.2s

    Note: Script is expecting a text file and is executed as: ./script_name <path-to-file>
