problem in lab 6.2

donquijotedelasnubes

hi there, I'm trying to do part 2 and 3 of the DNS labs on a google cloud VM instance running Centos stream 8 (because I scheduled the LFCS exam with that OS). And I' m getting this error:

/etc/named.conf:61: 'primary' unexpected

when typing this command:

[root@instance-1-centos-3 student]# named-checkconf -z

after adding this stanza:
zone "example.com." IN {
type primary;
file "/etc/bind/example.com.zone";
};

I tried using master as well. it passed the check , but when doing the service restart, it throws an error. I added the next stanza, and the result is the same. Can anybody help please?

journalctl -xe

This is my named.conf file:

   reduce such attack surface

Hello,
In man named.conf
under ZONE:
type ( delegation-only | forward | hint | master | redirect | slave | static-stub | stub );

Probably replace primary with master

Hi, can you please let us know what version of bind you are using , The labels primary/secondary should work.
