my problems are fixed
NCS enviroment DNS , error 13 no access
Problem was AppArmor
Fix : aa-disable novell-named
DHCPD, no interface entry in /etc/sysconfig/dhcpd
Start dhcpd, no interface
edit the file and put eth0 into the file
got the error, "no group"
found that the local dhcpd user in passwd has no group !
So the user was not allowd to read the file as "world"
add the group "nogroup" to the user
then the dhcpd can read the /etc/sysconfig/dhcpd
and start dhcpd successfull
