Un cordiale saluto a tutti.
Nell'opera di perfezionamento della mia infrastruttura ho notato questa cosa:
se eseguo questo comando:

ns1# dig syntech.cc axfr

; <<>> DiG 9.4.2-P2 <<>> syntech.cc axfr
;; global options:  printcmd

ns1#

Ottengo ==> MX	10 mail.syntech.cc.syntech.cc. (syntech.cc ripetuto)

Mentre al riavvio di bind, nei log, rilevo questa segnalazione:

Jul 20 12:40:33 ns1 named[25493]: stopping command channel on 127.0.0.1#953
Jul 20 12:40:33 ns1 named[25493]: exiting

'mail.syntech.cc.syntech.cc' has no address records (A or AAAA)
Jul 20 12:40:35 ns1 named[63808]: running

No trova il record A oppure AAAA per mail.syntech.cc.syntech.cc (ovviamente).

Questo e' il file di zona:

$TTL    3600

syntech.cc.     IN      SOA     ns1.syntech.cc. root.syntech.cc.        (

                                10800           ;       Refresh
                                3600            ;       Retry
                                604800          ;       Expire
                                86400 )         ;       Minimum TTL
;
syntech.cc.     IN      NS      ns1.syntech.cc.
syntech.cc.     IN      MX      10 mail.syntech.cc
;
jails           IN      A       192.168.1.210
ns1             IN      A       192.168.1.211
apache22        IN      A       192.168.1.215
mail            IN      A       192.168.1.221
syn             IN      CNAME   apache22.syntech.cc.

Domanda, dove ho sbagliato?

Grazie
Franco
