How to Disable SELinux
Security-Enhanced Linux (SELinux) is a type of access control integrated into 2.6 Linux kernels. SELinux can often interfere with host-target communication, so you might want to turn off this feature on your Linux host while doing embedded systems development.
To disable SELinux, check the file /etc/selinux/config. If it includes one of the following lines:
SELINUX=enforcing SELINUX=permissive
log in as root and change it to:
SELINUX=disabled
Reboot your computer to enable the changes to take effect.
