Hi Michael, Thank you for the suggestion. I will look into trying it out. Just a bit of a background. I am running CentOS 7. I don't even have "semanage" installed by default, but I am sure I can install it. I looked into the man page of "semange" (option "fcontext") not sure what exactly the command is doing. Any idea? Thank you, Ahmed.
