How to open ports on linux "5.6" 64 bit (Tikanga)
 

Hi all
I am new to Linux. I am installing oracle OBIEE 11g on Linux Red Hat 5.6 64 bits and I got stuck at ports not open error.

I tried adding the following line in the iptables file:

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 5900:5964 -j ACCEPT

Then Restart iptables service, But did not have any success still getting the same error.

Please Help? how do I open ports on my server.

Thanks

Have you tried the tool system-config-securitylevel-tui? It is a command based graphic tool for configure the firewall. Makes things a bit easier if you don't need advanced configurations.

Thanks for your response.

Yes I just tried system-config-securitylevel-tui command and the
secuty level is set to Enabled and the SElinux is permissive.

Please help?

Run the tool and go to customize. From there you can easily open up the ports
