Hi all, I edited my firewall configuration file (SuSEfirewall2) while trying to configure an ftp server. The good news: ftp server is up and running perfectly. The bad news: all other ports are blocked. :(
I noticed this morning the iptables firewall was not starting due to the fact that I rebuilt the kernel and forgot to include the relevent Netfilter modules. So I added those and rebooted. The firewall still fails, but rather that referring to the non-available ip_tables module, it now just says iptables.init[1290]: iptables: Applying firewall rules: iptables-restore: line 13 failed.
I'm a newbie at Centos. I need to open a few ports in Centos.
I've googled it a little bit, and found something like this.
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 143 -j ACCEPT
But it gives the following error when i try to restart iptables
iptables: Applying firewall rules: iptables-restore: line 13 failed
How can I open ports in Centos 6
I'm setting up a new Centos 5.6 system and can't get my iptables firewall to work correctly. it won't let me use SSH through it. I'm new to Centos but not to Linux or iptables.

Running Fedora 17 x86_64. I have opened a few ports using system-config-firewall. After saving and appling the changes, the ports still are blocked. If I stop and start the firewall, things appear to be working. When the machine boots up, the ports appear to be blocked. If I stop and start the firewall, things work as expected.
Anyone see this type of behavior?
I need a robust/reliable/elegant way to handle any error conditions while re-loading firewall rules, some background:
our servers are using whitelist mechanism, which means there should be a large volume of rules if some server need to talk many different destinations.
we have another tool to generate a firewall rule file, which will feed to iptables/ipfilter, with very rare chance that the file
I'm not sure what is causing this.I have a CentOS 5.4 box that I am trying to set up as an OpenVPN server. So I modified the firewall by running the following script:
When Sperical Cow hits the digital shelves sometime in late October or early November, users will have to get used to a new firewall management application. Sperical Cow is, of course the code-name for Fedora 18, the next stable release of Fedora.
Hello to all, Using GUFW to configure unclomplicated firewall. Reading the following tutorial --> https://wiki.ubuntu.com/BasicSecurity/Firewall. Restarts cause firewall to turn off. How do you maintain firewall on permanently? Is there a way to edit existing rulesets? If so, how? Any help would be greatly appreciated... traxster
