how to open a tcp port?
Title: Re: [CentOS] how to open a tcp port?
Hi,
Assumed that iptables has been disabled during installation, /etc/sysconfig/iptables might not be present on your system. Can you print iptables running configuration out by using:
iptables –L

I issued 'iptables -L' but it is returning just the followings :
'Usage: /etc/rc.d/init.d/iptables {start|stop|restart|condrestart|status|panic|save} '
Can you please let me know why?

But when I trying to reach this debug port ,as :
#telnet 172.16.17.132 4965
It cannot get through . So if the port is open , why I cannot reach it ?
Thank you

You're right but the point is to help him to know wether is firewall is
running or not... If /etc/sysconfig/iptables doesn't exist, iptables might
be running anyway !

All ports are open, but you really need some service to listen that port.
