However, nslint reports the following errors: > > nslint: missing "a": localhost. -> 127.0.0.1 > nslint: missing "a": localhost.org. -> 0.0.0.1 The first message means you're missing a localhost forward domain. Normally this won't matter, because you have a localhost entry in /etc/hosts, but you could add a localhost domain to named.conf which contains: ; ; BIND data file for local loopback interface ; $TTL 604800 @ IN SOA localhost. root.localhost. ( 1 ; Serial 604800 ; Refresh 86400 ; Retry 2419200 ; Expire 604800 ) ; Default TTL @ NS localhost. @ A 127.0.0.1 The second one recommends adding a line like: localhost IN A 127.0.0.1 ... to your gilmer.org zone, using no "." at the end, to create a localhost.EXAMPLE.COM entry. > If I add the line: > > localhost.
