Dear All
On my RedHat 9 , I want to open tcp port 4965 but my server does not contain /etc/sysconfig/iptables . Can you please let me know how to open this port ?
Thank you
First, are you sure you need to open the port on that machine? Make sure you are opening the port on whichever machine your firewall runs on - which is not guaranteed to be on the machine you are working on. Its often your gateway machine, which connects you to the Internet.
If you have the right machine, there are other ways that a firewall can be set up. You can search the whole /etc directory tree for mention of iptables:
su
cd /etc
grep -ir iptables *
If you want to see your current in-memory firewall setup:
su
iptables -L -v

Thank you for your reply . But my server is returning as :
#iptables -L -v
Usage: /etc/rc.d/init.d/iptables {start|stop|restart|condrestart|status|panic|save}
Can you please let me know what is in-complete on my RedHat 9 server ?
For some strange reason your path seems to be directing you to the iptables script in /etc/init.d before it goes to the bin directory where the iptables binary is (try echo $PATH to see). On my system the iptables binary is at /sbin/iptables.
You can try /sbin/iptables -L -v, or if its not there, you can search your whole system for the iptables binary:
find / -iname iptables
...but you should probably take Chris' advice and upgrade.
For the iptables , I made use of :
#/sbin/iptables
As there is another similar machine from third party that I have remote access to it , I compared them with :
#locate iptrans
And I found some missing packages on mine that I need to add.
Thank you for your help
