yum install firewalld

then enabled and rebooted

systemctl enable firewalld   
reboot

I am now be able to login using ssh but firewalld does not come up

[root@~]# firewall-cmd --state
failed

[root@~]# firewall-cmd --get-default-zone
<empty line>
[root@~]# firewall-cmd --get-active-zones
<empty line>
[root@~]# systemctl status firewalld

Hint: Some lines were ellipsized, use -l to show in full.

If i try the following I still get errors:

[root@/]# firewall-cmd --zone=public --change-interface=eth0
Error: 'filter'

How can I solve this???

  • The OVH customised Centos kernel is missing the required packages to allow firewalld to run correctly. This occurs on their Centos dedicated systems and VPS. They are of the opinion there is no problem. Your options are to change the kernel or change the whole OS image. – Taylor Taff Jan 11 '20 at 16:52
