Perform either of the following: ; Enable in-line signing in each zone configuration by setting inline-signing to yes value. For example: zone "cisecurity.org" { type master; file "/etc/named/masters/cisecurity.org"; key-directory "/etc/named/keys"; inline-signing yes; auto-dnssec maintain; }; Reload the server configuration and zones. rndc reload Or if using manual or scripted zone signing instead of inline-signing, then perform the following. ; Include the signing keys at the end of the zone file to be signed.
