      @fuznutz04 - https://mxtoolbox.com/NetworkTools.aspx - If you go to the tcp option. I don't think there is a udp option though.

          That one is almost identical to the yougetsignal one. Very simple and straight forward. Do you see any risk in using these tools?

                Any risks using online tools? Possibly, but your servers is already at risk since its accessible from the Internet anyway.

                      I like a lot this web:

                      portquiz.net

                      Test a port using a command

                      $ telnet portquiz.net 80
                      Trying ...
                      Connected to portquiz.net.
                      Escape character is '^]'.

                      $ nc -v portquiz.net 80
                      Connection to portquiz.net 80 port [tcp/daytime] succeeded!

                      $ curl portquiz.net:80
                      Port 80 test successful!
                      Your IP: 213.97.29.103

                      $ wget -qO- portquiz.net:80
                      Port 80 test successful!
                      Your IP: 213.97.29.103

                      For Windows PowerShell users

                      PS C:> Test-NetConnection -InformationLevel detailed -ComputerName portquiz.net -Port 80

                        You can also use Nmap
                        https://nmap.org/book/man-port-scanning-basics.html
                        I use Angry IP Scanner for that but a lot of tools use NMAP

                          nmap is so much lighter and faster than other tools, too.
