I am using Oracle Enterprise Linux 5.0.Here if I open the port number 2372 by using iptables, it will not open.I am checking this port status by using the command " telnet 192.168.0.1 2372". I get the message as following
telnet: connect to address 192.168.0.1: Connection refused
telnet: Unable to connect to remote host: Connection refused
Is this procedure correct to get the port status? Can anybody please guide me to open this port?
Just to clarify a bit as to the feedback you've received: For a port to be open, something needs to be listening on it. Making a rule allowing packets into a certain port won't open the port - it will still be closed until something actually listens on it. The netstat command you've been given would show us if anything is actually listening on port 2372, which I suspect isn't the case.
