Open port 4949 on RedHat 7.3

Hi Guys,

We have a RedHat 7.3 server (2.4.18-3).

I need to open port 4949 (in and out).

/etc/services
poll          4949/tcp                        # poll
poll          4949/udp                        # poll

I've tried opening this port with:
iptables -I INPUT -p tcp --dport 25 -j ACCEPT
iptables -I OUTPUT -p tcp --dport 25 -j ACCEPT

Also tried this:
iptables -A INPUT -p tcp --destination-port 4949 -j ACCEPT
iptables -A OUTPUT -p tcp --source-port 4949 -j ACCEPT

This port still seems to be closed.

netstat -an | grep 4949     doesn't return anything.

How would I open port 4949 for this system?

Thank you.
[root@poll]# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     tcp  --  anywhere             anywhere           tcp dpt:receive_wrapper
 
Chain FORWARD (policy ACCEPT)
target     prot opt source               destination
 
Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     tcp  --  anywhere             anywhere           tcp dpt:receive_wrapper

You can open a port if you put the right daemon in listening mode. For example you can open port 22 by executing SSH daemon, or port 23 by executing telnetd daemon (via xinetd).
Maybe you can install Munin (http://munin.projects.linpro.no/) and you'll get port 4949 open, but I don't know if this is what you need.
So, the question is: why you need port 4949 open? What service do you need?
