Custom DNS server

[can79]

I have a solution for custom NS records. (based on ispCP 1.05)
I think dev team can improve.


NOTE.
After you customize for each domain you have to create A records and NS records
So there is no longer automatically ns records created.
advantage is that you can yourself edit ns records for each domain.

This will only a tip for dev team.
I do not support on pm. and you are responsible for errors.
before you start. make backup

it works as follows;

Change /etc/ispcp/bind/parts/db_e.tpl and /etc/ispcp/bind/parts/db_master_e.tpl as follows

Code:

$TTL 12H
$ORIGIN {DMN_NAME}.
@               IN              SOA             ns1.{DMN_NAME}. postmaster.{DMN_NAME}. (
; dmn [{DMN_NAME}] timestamp entry BEGIN.
                {TIMESTAMP}     ; Serial
; dmn [{DMN_NAME}] timestamp entry END.
                8H              ; Refresh
                30M             ; Retry
                4W              ; Expire
                3H              ; Minimum TTL
)

{DMN_NAME}.     IN              A               {DMN_IP}
localhost       IN              A               127.0.0.1

; CNAME for VHCS compatibility
ns              IN              CNAME           ns1
; CNAME for mail transfer
; CNAME for web transfer
; sub [{SUB_NAME}] entry BEGIN.
; sub [{SUB_NAME}] entry END.

; dns [{MANUAL_DNS_ID}] entry BEGIN.
; dns [{MANUAL_DNS_ID}] entry END.

Change in /var/www/ispcp/gui/client/dns_edit.php following lines.
