Do I need to restart Named after making DNS changes?
 

Hi,

I'm fairly new to Linux. We're using RedHat 9.

I think after making DNS record changes I need to increment the Serial Number by one, save the .dns file and restart named. Is this correct?

I'm also having trouble restarting named. I did some google searches and they suggest I need to do /usr/sbin/ndc restart but when I do that I get an error message that states there's no such file.

One article I found suggests, if I don't have ndc, I must have an old system. It suggests I do /usr/sbin/named restart.

However, when I try that it's expecting more parameters.

So I'm a little confused about the process. I'm also not sure if I need to go to the secondary server and do anything after making my changes on the primary server.

I'd appreciate some pointers on how to handle DNS on a Linux box. Thanks.

after each change to your .dns file, you must change the serial number - increment it by one.

The unwritten standard is yyyymmddnn e.g. if you made a change for the 5th time today, you can have a serial number of 2004072205.

You do not really have to restart named.

What if I create a new dns record?
 

Do I need to restart named if I create a new dns record i.e. a new domain?

And how do I restart named anyway? Thanks.

you need not restart named. You can simply reload it.

If you are using RedHat/Fedora/Mandrake OR simply Please note ` is not apostrophe.

Do I have to create DNS records on the secondary server?
 

If I'm creating the necessary records for a new domain, I do the following on the primary server:

1. MyDomain.com.dns file in /var/named
2. Put a reference to MyDomain.com.dns file in /etc/named.conf
3. service named reload

After this, do I need to go through the same steps on the secondary DNS server? Obviously, I set it so that the records read "slave" instead of "master" on the secondary server.

Thanks.

You do not have to do anything to the secondary server .. only edit the named.conf on your secondary server to make it aware of the new domain.

Thank you all
 

Thank you very much all for your valuable help.

if 'ndc' isn't available try:

rndc restart
