chkconfig iptables off

In Production Environment:

Add the following lines in iptables for Trapper (10051); Client(10050) & httpd (80)

[code]
vi /etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 10050 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 10051 -j ACCEPT
[/code]

Restart the Firewall

[code]service iptablesrestart[/code]
