Hi Martin,
here is what I have on my DNS-server:
; <<>> DiG 9.1.3 <<>> localhost axfr
;; global options: printcmd
localhost. 86400 IN SOA localhost. root.localhost. 42 10800 900 604800 86400
localhost. 86400 IN NS echnaton.n.
localhost. 86400 IN NS echnaton.styx.
localhost. 86400 IN NS echnaton.lomiheim.
localhost. 86400 IN NS echnaton.niflheim.
localhost. 86400 IN NS echnaton.serveftp.com.
localhost. 86400 IN A 127.0.0.1
localhost. 86400 IN SOA localhost. root.localhost. 42 10800 900 604800 86400

It is important that you give at least one NS records. I have not
read it in the book. Joe Baptista has shown it to me.
If only localhost claims to know localhost and if localhost is
not your DNS-servers then it bites :)
Kind regards,
Peter (DL2FBA) and Karin
