Hi, I’m trying repair problems from notices on Zonemaster.
I’ve got two of them which I can’t solve.
"NAMESERVER NOTICE Nameserver domain/IP allow zone transfer using AXFR."
It’s mean that my secondary server is allowing AXFR transfers from anyone? I changed WEBMIN/SERVERS/BIND DNS Server → Zone defaults : Allow transfers from listed…
And I’ve got the same NOTICE from Zonemaster test.
My second problem is:
DNSSEC WARNING DNSKEY with tag 9952 and using algorithm 8 (RSA/SHA-256) has a size (1280) smaller than the recommended one (2048).
WEBMIN/SERVERS/BIND DNS Server → Zone defaults : Initial key size from Average size to other size in bits (2048)
and notihig got better.
