REJECT     all  --  0.0.0.0/0            0.0.0.0/0           reject-with icmp-host-prohibited

Run the following command:

You can view it. If this rule exists, manually change the port 8989 to be added and place it on the top line of the rule. Edit the/etc/sysconfig/iptables file:

-A INPUT -p tcp -m state --state NEW -m tcp --dport 8989 -j ACCEPT

Put in:

-A INPUT -j REJECT --reject-with icmp-host-prohibited

. The final result is as follows:

-A INPUT -p tcp -m state --state NEW -m tcp --dport 8989 -j ACCEPT-A INPUT -j REJECT --reject-with icmp-host-prohibited

After editing, restart the iptables firewall. Command:/etc/init. d/iptables restart
