I have a CentOS-6.6_64bit server, with Cent-OS Web Panel
Suddenly, all my sites are down, I cannot login through SSH, only through VNC through Web Browser and I keep getting this error:
Firewall: *UDP_IN Blocked* IN= etc0 OUT= MAC= FF:ff:ff:ff:ff
I need to:
- have all my sites back up.
- implement more server security
- all this have to be done directly on my PC through Team Viewer, I cannot provide direct access to server
