      I previously used to use this website: https://www.yougetsignal.com/tools/open-ports/ to verify open/closed ports on specific servers to the public. Do you guys use any other tool to test open/closed ports? I can do this easily with nmap of course, but I would like to preferably have a website tool to give others access to.

        @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
                          https://angryip.org/

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