Προσπαθώ να φτιάξω ένα Caching Server με την χρήση του bind και των ubuntu 12.04 . Όμως κάθε φορά που ενεργοποιώ το dnssec-validation στο syslog εμφανίζονται:

και άλλα παρόμοια μηνύματα ενώ καθυστερεί και πολύ η εμφάνιση των σελίδων (αν εμφανιστούν ποτέ).
Το αρχείο named.conf.options έχει τα παρακάτω:

Μάλλον κάπου έχω κάνει λάθος στις ρυθμίσεις ή έχω παραλείψει κάτι. Μπορεί κανείς να δώσει καμιά ιδέα ???
Ευχαριστώ εκ των προτέρων
