>selinux enabled ? Looks that way. You either need to write some policy rules to allow the 2 daemons to talk when started as services - eg read audit log Yes, i Have apparmor, and i see as the dhcpd tryes to create a file in the root: apparmor="DENIED" operation="mknod" profile="/usr/sbin/dhcpd" name="/tmp-sDNmo4KlSV" Why DHCPD does it?
