How To Open Port 443 On RedHat 7.1
 

Hi, I'm running apache on redhat 7.1. When I install the redhat, I customize the firewall configuration to allow incoming on port 80, but I forgot to open port 443. I did ran a probing port test, and I was right. Port 80 is open, and port 443 is closed.

Anybody know how to open port 443 on redhat?

Thanks.

If you're using the built in RH setup for firewall - just type 'setup' at the command prompt and it will have an option for FW config.

Hey, It worked. Thank you.

I have one more question. How can I configure it without going to setup? Is there any other way that is more general to linux? Thanks again.

Yes - if you go back into setup and disable the firewall. The go back to the console - you can use the program ' iptables ' to create your firewall rule set. It's easier to just do a 'man iptables' than for me to try and discuss the syntax.

To other programs you'll want to know about are 'iptables-save' and 'iptables-restore' - because the system will lose your settings after a reboot.

After you're done creating your rule set type 'iptables-save > /etc/firewall.conf' and it will save your configuration to that file in the /etc directory.

Then edit your /etc/rc.d/rc.local file and append 'iptables-restore < /etc/firewall.conf' to the end, which will restore your settings each time upon boot.

At least this is how I do it.. there maybe more than one way to skin a horse, but this works for me.

the file is /etc/sysconfig/iptables


edit the file and when you get it like you want it run this


/etc/rc.d/init.d/iptables restart

try that

also the same command for stop, and start



don't run lokkit or it will rewrite the script.
