Check in you firewal rules for blocking and change it.

What do you want to do exactly ? Install specific application, listening on that ports ?

frankly speaking, you cannot open or close a port.

process or daemon itself can open ports. so you first identify, which process can open the ports that you specified.

[Karthikeyan.j]

To Check whether the Process is running and listening on the ports

netstat -an | grep port number

or netstat -tulp | grep port number

or Just telnet ipaddress portnumber if the session opens the port is open and listening .

To check if the firewall is enabled .
service iptables status
