Just wondering why SELinux is diabled in the ISP server howto? Would it cause any problems anableing it?
SELinux does not contain rules to support the ISPConfig apache webserver on port 81 and several other scripts. Ify ou enable SELinux, ISPConfig wont work anymore.
This is not quite true. According to CentOS WiKi: It will be very nice if ISPCONFIG will work, at least at some point in future with SELINUX.
