Hi.
I have never bothered with SELinux till now. I have been instructed to deploy SELinux on all new servers.
I have an Exim email server the is in a chroot jail. Now I have to enable SELinux. Does it need to be applied from within the chroot jail ? or should it be done from the host OS, and or both ? I have yet to find a howto on achieving this.
SELinux is enabled in the kernel. Working on your staging machine (not production), set up your chroot, label every item like in the main system, chroot the daemon then watch /var/log/audit/audit.log for violations. Cat the log through 'audit2allow' to see what's causing them.
