Missing Requirements:
The File “/usr/lib/sysadmin/includes.php” must exist.
In custom installation on Centos 7 i have this error. Is there any way i can fix this problem ?
I really like to enable the system firewall because using systemctl start firewalld is not working and i have added my public ip address on whitelist using this command: firewall-cmd --permanent --zone=trusted --add-source=1.2.3.4
Thanks for replay on my post.
So if System Admin is not working can you guide me on how to add firewall rules based on the firewalld
all i need rules to drop all incoming connection and allow only list of ip address?
