WebSphere Installation - Port 80 is Not Avaialbe

while installing Maximo/WebSphere, you may encounter an issue with Availability of Port (mostly Port 80).

Resolution:

Generic about checking Port Availability:

To check which all ports are being used, run this on command prompt (in windows):
         netstat -an
Output of above command will show all the ports which are in use.

To check a specific port (e.g. Port 80), run the following command (in windows):
         netstat -an | find "port_number"
         netstat -an | find "80"
If above command returns any output, that means port is in us.
If above command doesn't return any output, Port is Free, and can be used.
