How To Open Ports in RedHat ?

how can i open ports i need in red hat server vs root access ?
# 2  
What do you mean by opening a port?

If an application server binds to the port to listen incoming traffic or have to send out any messages, the port must be open. Otherwise, it is closed. I don't think you will manually open a port.

Or do you mean to configure the firewall to enable certain ports that are otherwise blocked by default?

i wont to install ircd on my server my ports i need 6663-7000 closed. vs what command can i open them ?
# 4  
When you start ircd (if its configured correctly), it should open those ports.
# 5  
This port range is > 1024. You don't have to be root to run this program. You don't have to manually open them. The program will open them as needed.

but i wont to run ircd not from root access, i wont from user. so program can't open ports coz has no access
