Hi all, auditor (Beta 7) answer with many message without a specifiq zone :
(wihtout)
ods-auditor --zone --signed
Auditor started
Auditor starting on archi.amt
/usr/local/lib/opendnssec/kasp_auditor/preparser.rb:54:in {{initialize': uninitialized constant Dnsruby::ZoneReader (NameError)
from /usr/local/lib/opendnssec/kasp_auditor.rb:179:in }}new'
from /usr/local/lib/opendnssec/kasp_auditor.rb:179:in {{normalise_and_sort'
from /usr/local/lib/opendnssec/kasp_auditor.rb:133:in }}run_with_syslog'

from /usr/local/lib/opendnssec/kasp_auditor.rb:83:in `run'
from /usr/local/bin/ods-auditor:112

And correct now :

root@portable:/mnt/Compilation/opendnssec-1.0.0b7/auditor# ods-auditor --zone --signed 1.168.192.in-addr.arpa
