Hello,
I try to give a dynamic IP to a name, using nsupdate. This works fine,
but after some hours the IP is gone from the master (which I update).
Something like this:
Host home.customer.nl not found: 3(NXDOMAIN)
The IP is then still available from the slaves, what gets it from the
master.
I do something like this to give the IP, using a script:
root@server:~# /usr/bin/nsupdate -k /etc/customer.key
> server ns1.vandervlis.nl
> zone customer.nl.
> update delete home.customer.nl.
> update add home.customer.nl. 3600 A 1.2.3.4
> send
> quit
I don't see anything about the removal in the logs. But I saw a "freeze"
and a "thaw" in the logs for the domain.
Any idea why the IP removes after some time?
Hmm, I see I have cronjob what causes this problem:
-----
# change serial
SERIAL=`named-checkzone $domain $domain | egrep -ho '[0-9]{10}'`
sed -i 's/'$SERIAL'/'$(($SERIAL+1))'/' $domain
# sign zone
rndc freeze $domain
dnssec-signzone -S -K /etc/bind/keys/ -g -a -o $domain $domain
rndc reload $domain
rndc thaw $domain
-----
But how could I refresh the key without loosing the IP?
With regards,
Paul
