Hello, I'll help you though I'm working for Meinberg, not for Hopf ;-)

For a first test you can stop AppArmor and see whether ntpd then works correctly. If AppArmor shall be used it must be configured to allow access to the refclock for ntpd: Yast2 -> Novell AppArmor -> Edit Profile Select profile /usr/sbin/ntpd Add entry: /dev/??? # where ??? must be the device /dev/hopfclock0 points to Mark allow for: Read, Write, Link This generates a new entry: /dev/??? rwl Please note the symbolic links (e.g. /dev/hopfclock0) are also created new after every reboot. If this doesn't appear to happen you must create an udev rule for this.
