@george1421 Thank you for the clarification. This is duly noted. Appreciate the help, you saved my ass today basically.

@george1421 Thank you George. That solved it. I know I deleted images before from the web interface but when I looked at /images I saw the directories were still there with the files intact. So I manually removed everything I needed removed. Is that a bug in the web interface?

@george1421 This is what I get. Seems like that would be the case.

Hi everyone.

I wanted to log in to the webUI of my FOG server to check on an image but it came back with a “Database connection unavailable” error on the browser. I logged in to the server and when I ran “systemctl restart mysql” it came back with this error:

Job for mariadb.service failed because the control process exited with error code.
See "systemctl status mariadb.service" and "journalctl -xe" for details.

so I ran “systemctl status mariadb.service” and this is what it’s coming back to me with:

Job for mariadb.service failed because the control process exited with error code.
See "systemctl status mariadb.service" and "journalctl -xe" for details.

I found a couple of “fixes” on Google searches that has not helped. Can anyone tell me what I’m missing here? Or maybe point to the right direction for troubleshooting this?

Re-installing the database is my last resort and I’m willing to if I have to but can anyone advise what the process for that would be? I have 6 laptops and 2 desktop that I need to image but with my FOG server being down at the moment, I am stuck in the water. Any help will be greatly appreciated. Thanks in advance.

Re: Firewall Configuration

I’m trying to add this configuration to my IPtables:

echo "IPTABLES_MODULES=\"nf_conntract_tftp nf_conntrack_ftp nf_conntrack_netbios_ns\"" >> /etc/sysconfig/iptables-config
for port in 80 443 21 3306 2049 20048 111 138 139 445; do iptables -I INPUT 1 -p tcp --dport $port -j ACCEPT; done
for port in 69 111 4011 137; do iptables -I INPUT 1 -p udp --dport $port -j ACCEPT; done
service iptables save

but when I run the first line it gives me the error no file or directory. I checked the directories under /etc and did not see /sysconfig. Do I have to create that directory manually? I am running 1.5.9. Reason I’m digging around with IP tables is because I’m trying to find a way around securing NFS but on the wiki it says that there currently is no way to do it. I’m trying to see if I can find a way to at least restrict traffic to the server to one subnet on our production environment.
