Cant open port
 

Hi,

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?

which rule did you used to open the port?
which service are you running behind the port?

telnet is ok to check the port

Run this command & put here the output of the command

netstat -tanp | grep 2372

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.

Thanks for your replies

I have added following line in iptables

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 2372 -j ACCEPT


I am not running any service behind this port

No response for following command
netstat -tanp | grep 2372

As told in previous posts, you need to run a service behind the port.
ex. behind port 22 runs ssh deamon.
