Port Blocking.

Hi,

Is there command that can run from desktop to check whether a particular port is blocked ?

Regards

Assuming your using windows here. The following should show you the firewall port configuration.

netsh firewall show portopening

Or for more info:

netsh firewall show portopening ENABLE

You can also see the actual currently open ports using this command:

netstat -a

It will show LISTENING ports and ESTABLISHED ports. The LISTENING are the ones that are open by server processes in your PC. I also use a freeware called ActivePorts which does the same thing but shows also the executable file names of the processes.

Thank you very much Sir,

Regards
Alok.
