Need to be aware
The native port bound in 1.rinetd.conf must not be occupied by another program
2. The system firewall running rinetd should open the bound native port
For example:
-A rh-firewall-1-input-m state--state new-m tcp-p TCP--dport 1111-jaccept
-A rh-firewall-1-input-m state--state new-m tcp-p TCP--dport 2222-jaccept
