How to make sure that a certain Port is not occupied by any other process
You can use "netstat" to check whether a port is available or not.
Use the netstat -anp | find "port number" command to find whether a port is occupied by an another process or not. If it is occupied by an another process, it will show the process id of that process.
You have to put : before port number to get the actual output
Exnetstat -anp | find ":8080"
netstat -ano|find ":port_no" will give you the list.
a: Displays all connections and listening ports.
n: Displays addresses and port numbers in numerical form.
o: Displays the owning process ID associated with each connection .
example : netstat -ano | find ":1900" This gives you the result like this.
