See Open Ports in a Linux PC ( Localhost/Remote Machine)
I am writing a small post that will help you just to see what ports are open in a particular remote/local machine. we are going to use tool name as nc. To install it , open your terminal and type as # yum install nc After installing , you can use it with nc -zv xxx.xxx.xxx.xxx <Port> for example: nc -zv 192.168.1.100 80 if you want to do that for 2-3 ports nc -zv 192.168.1.100 80 8009 if you want to do scanning for range of ports nc -zv 192,168.1.100 80-8080 hope it will help you.
