I have a primary (master) and a secondary (slave) BIND9 DNS on DEBIAN9. See full config here: old Post
root@server1:/etc/bind# named -v BIND 9.10.3-P4-Debian <id:ebd72b3>
On my secondary NS (Nameserver) my zonefile /etc/bind/forward.my-domain.com is not readable.
I get something like: ^@^@^@^B^@^@^@^A[ p*^@^@^@^@^@^@^@^@
If my primary NS is going down the secondary server keeps the DNS tasks. Resolving works fine. How can I add new DNS enries until primary is back? It could also happens that primary can't be restored...
