DNS zone file wrongly overwritten wit DHCP update
Hi
I hope i have chosen the correct forum .
I' an using Centos 6.8 and i am testing DDns en it works file until i reboot the server . After the reboot i get following error :
Starting named:
Error in named configuration:
zone nw.cvotest.local/IN: loaded serial 37

I found out that the reverse zone file is overwritten bij the DHCP update process
the original file was
$TTL 3H
@ IN SOA lserver.nw.cvotest.local. root.nw.cvotest.local (
1 ; serial
20 ; refresh
1800 ; retry
604800 ; expire
3H ) ; minimum
; Name Servers
@ IN NS lserver.nw.cvotest.local.
@ IN NS dmz.nw.cvotest.local.
@ IN NS Wserver.nw.cvotest.local.
;pointers
100 IN PTR dmz
200 IN PTR wserver
after the DDns update i get:
$ORIGIN .
$TTL 10800 ; 3 hours
@ IN SOA lserver.nw.cvotest.local root.nw.cvotest.local. (
7 ; serial
20 ; refresh (20 seconds)
1800 ; retry (30 minutes)
604800 ; expire (1 week)
10800 ; minimum (3 hours)
)
NS lserver.nw.cvotest.local.
NS dmz.nw.cvotest.local.
NS Wserver.nw.cvotest.local.
$ORIGIN 4.17.172.in-addr.arpa.
100 PTR dmz
200 PTR wserver
$TTL 300 ; 5 minutes
50 PTR dmzclient
51 PTR Wclient10.nw.cvotest.local.
I have 2 workstation's with get the correct ip adress 172.17.4.50 and 51(given by the DHCP server, this is the same server) and NSlookup and ping works fine until the reboot .
If i remove the first $ORIGIN everthin g is OK until the next update .
Thanks if anyone can give me a clue on how to get rid this .
Sorry for my english , this is not my native language.
