Comment on Godaddy VPS by SEO Gold Coast Services.

I’m having this issue with a new Centos 7 VPS and looks like it’s to do with the OpenVZ container.

The server starts with all ports except 22 and 80 closed and iptables enabled, but NOT active because the default iptables file (/etc/sysconfig/iptables/) fails on line 14 (the commit line). This is the entire file:

# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
there's a blank line here

The COMMIT line is line 14, but I’ve tried adding commit between each rule (after each -A INPUT” rule) and it fails at the first rule.

Can only get iptables to run via the “service iptables save” command which results in iptables running, but no rules saved.

# iptables -S

The weird thing is ports 22 and 80 are open even when iptables is disabled at boot or has no rules.

I’ve tried disabling iptables and rebooting and ports 22 and 80 are still open, everything else blocked.

Firewalld wasn’t installed, after disabling iptables and installing firewalld

# sudo firewall-cmd --state
not running


# firewall-cmd --set-default-zone=public
Warning: ZONE_ALREADY_SET: public

The "sudo ifconfig" command outputs "sudo: ifconfig: command not found"

At this point I’m stuck.

I know iptables isn’t working as it should and firewalld when installed says it’s not running.

To confuse things even further I’m trying to install Virtualmin and it installs and opens ports for MYSQL and Usermin (port 20000), but fails to open other ports for Webmin (10000), POP3, FTP…

Godaddy support are useless, they don’t appear to understand the concept that the server is starting with a fault in the iptables setup.

What I’d really like to know is how ports 22 and 80 are open when iptables and firewalld aren’t enabled? Is there another firewall built into Godaddy servers by default???

There’s also some info about the iptables issue at
