DNS Updates

[Fuad_1]

Hi,

How I update 'A' record only in DNS, changing IP address, without updating all DNS databases.

Thanks.

[Steven E. Protter]

You change the A line in the database record(s) that contain that IP address.

Generally they are kept in /var/named or /var/named/chroot/var/named

Then you restart the named daemon.

/sbin/init.d/named stop
/sbin/init.d/named start

Hi,

There is no way without restarting named daemon. You have to restart the named service.

/sbin/init.d/named {start|stop}

Regards,

you can try

#sig_named restart

You don't have to restart bind to update a record....use nsupdate.

Fuad,

Elaborate on the below part.
"without updating all DNS databases."

Are you looking to only update the local named server and not any secondaries or served servers?

Explain your environment.

[Florian Heigl (new acc)]

with bind8 and above the proper way of updating is after manually updating the zone file (and it's serial) is to issue
ndc reload [optional name of zone]

ndc and it's remote-enabled counter part rndc need extra setup, if this was not yet done, a kill -1 is the way to go.
