how to open port in linux

hi experts,

I'm using Linux Centos kernel 2.6
Here is the print out of some my port :

Code:
tcp        0      0 127.0.0.1:10080             0.0.0.0:*                   LISTEN      
tcp        0      0 127.0.0.1:10081             0.0.0.0:*                   LISTEN      
tcp        0      0 127.0.0.1:10082             0.0.0.0:*                   LISTEN      
tcp        0      0 ::1:10080                   :::*                        LISTEN      
tcp        0      0 ::1:10081                   :::*                        LISTEN      
tcp        0      0 ::1:10082                   :::*                        LISTEN

Actually i want the port can be access from the other machine. I try to configure the iptables below : but still have failed when implemented :

Code:
[root@localhost ~]# cat /etc/sysconfig/iptables
-A RH-Firewall-1-INPUT -m state .state NEW -m tcp -p tcp --dport 10079 -j ACCEPT
-A RH-Firewall-1-INPUT -m state .state NEW -m tcp -p tcp --dport 10081 -j ACCEPT
-A RH-Firewall-1-INPUT -m state .state NEW -m tcp -p tcp --dport 10082 -j ACCEPT
-A RH-Firewall-1-INPUT -m state .state NEW -m tcp -p tcp --dport 10083 -j ACCEPT
-A RH-Firewall-1-INPUT -m state .state NEW -m tcp -p tcp --dport 10084 -j ACCEPT
-A RH-Firewall-1-INPUT -m state .state NEW -m tcp -p tcp --dport 10089 -j ACCEPT

[root@localhost ~]# /etc/init.d/iptables restart
Flushing firewall rules: [  OK  ]
Setting chains to policy ACCEPT: mangle filter nat [  OK  ]
Unloading iptables modules: [  OK  ]
Applying iptables firewall rules: iptables-restore: line 1 failed
[FAILED]

I'm trying to access the port from other machine still failed.

Code:
[~]$ telnet 74.82.162.xx 10080
Trying 74.82.162.xx...

telnet: Unable to connect to remote host: Connection timed out

Anybody can help me?
Thanks.
