Open a port CentOS

Question

I'm new in CentOS and I'm trying to create a little script in Python, something like:

$ python -m SimpleHTTPServer

If I try to access port 8000 in my web browser, I don't get access, however if I turn off the firewall with:

$ system-config-firewall-tui

I'm able to access the service.

I just need to access port 3343 and 8880 but I don't want to disable the firewall.

Solution

Try something like this:

$ iptables -A INPUT -p tcp --dport 3343 -j ACCEPT
$ iptables -A INPUT -p tcp --dport 8880 -j ACCEPT

So it works with the firewall off, but not when it's on?

Exactly! I think i need to configure the firewall to access only to this ports, but i dont know how :(

if IPTables are not running you may need to run "system-config-securitylevel" first. And if you want them to be permanent save them by running "/sbin/service iptables save"

@PurindaGunasekara - getting ahead of ourselves. If these rules solve the issue then yes, we can make these permanent.
