falha na zona de carregamento de 'myzone.local.zone': no ttl

Question

Eu executei o seguinte comando para o dnssec no debian 8. Mas recebo o erro:

# dnssec-signzone -A -3 $(head -c 1000 /dev/random | sha1sum | cut -b 1-16) -N INCREMENT -o myzone.local -t myzone.local.zone
dnssec-signzone: warning: Kmyzone.local.+007+16956.key:5: no TTL specified; zone rejected
dnssec-signzone: fatal: failed loading zone from 'myzone.local.zone': no ttl
