Excellent to ask - as I warned earlier, there was room for things like
this to happen with my brain getting muddied by all of the various
symptoms I'm fighting. That said, I get:
> 127.0.0.1
Server: 127.0.0.1
Address: 127.0.0.1#53
1.0.0.127.in-addr.arpa name = localhost.
> localhost
Server: 127.0.0.1
Address: 127.0.0.1#53
Name: localhost.hosehead.dyndns.org
Address: 127.0.0.1
------------------------------------------
The localhost.hosehead.dyndns.org wasn't a problem before the big
restart, and I haven't found anything in the documentation to cause that
to *not* happen. /etc/bind/db.local reads:
;
; BIND data file for local loopback interface
;
$TTL 604800
@ IN SOA localhost. root.localhost. (
5
604800
86400
2419200
604800 )
;
@ IN NS localhost.
@ IN A 127.0.0.1
Administrator.localhost. IN RP
kahnt.hosehead.dyndns.org. Administrator
Hosehead.localhost. IN HINFO i686 Linux
Mail.localhost. IN MX 1 hosehead.dyndns.org
-----------------------------------------------------
and /etc/bind/db.127 reads:
;
; BIND reverse data file for local loopback interface
;
$TTL 604800
@ IN SOA hosehead.dyndns.org. root.hosehead.dyndns.org. (
1 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS dns.hosehead.dyndns.org.
1.0.0 IN PTR localhost.
-----------------------------------------------------
and for the heck of it, this is /etc/hosts:
127.0.0.1 localhost hosehead
192.168.1.1 hosehead.dyndns.org hosehead
205.189.48.3 adan.kingston.net
205.189.48.6 border1.kingston.net
# The following lines are desirable for IPv6 capable hosts
# (added automatically by netbase upgrade)
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
::FFFF:127.0.0.1 localhost
::FFFF:192.168.1.1 hosehead.dyndns.org hosehead
---------------------------------------------
Hopefully I haven't buggered anything in any of these, but most have
been through at least a couple of system restarts (particularly all of
the bind stuff) and so shouldn't be functioning differently (I hope).
