Outgoing port tester

Sorry. This version is limited. I had to disable PHP because of PHP2Shell vulnerability.

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 test successful!
Your IP: 

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

# For Windows PowerShell users
PS C:\> Test-NetConnection -InformationLevel detailed -ComputerName portquiz.net -Port 80

Test a port using your browser

In your browser address bar: http://portquiz.net:XXXX

Your browser can block network ports normally used for purposes other than Web browsing. In this case you should use the telnet or netcat commands to test the port.

Please also note that this server uses some port for real services (22, 25), so testing with your browser on those ports will not work.
