Named stops working and named.conf empty

[Snowman30]

Ive just seen a very weird issue across all of our servers which are setup the same way and running R30

named was still showing to be working but everyones nameservers appear to be lame and so sites stopped working

a check of named.conf shows all the domains missing

ive had to run

/scripts/fixndc
/scripts/rebuildnamedconf
and restart named to get the sites back online.

Is this a known bug in the current Release?

Anyone know why it would be happening?

Same here on one of our servers...

Nevermind...fixed it.

/scripts/rebuildnamedconf

then restarting named corrected it for us.

It happens because you have installed the caching-nameserver rpm which provides a simply configured named.conf whenever that rpm is updated. To avoid the problem in the future, add caching-nameserver* to your yum or up2date exclude list.

Thanks for the infos, I had exactly the same problem. What else should be in this line? My exlude line looks now like this:

exclude=httpd* mysql* php* perl* mod_ssl* kernel* spamassassin* caching-nameserver*

I currently use the following, I wouldn't recommend using perl* anymore and would stick to just perl otherwise you can have problems installing other rpms that have perl module dependencies:

exclude=courier* mysql* spamassassin* httpd* perl mysql* php* mod_ssl* imap* squirrelmail* caching-nameserver* kernel*

Hey, thanks for the tip, this happened to me last night too: I added a new domain and completely wiped out the named.conf file except for the caching-nameserver's named.conf + the new domain I just added.

Besides adding caching-nameserver to the yum exclusions, do I also have to

a) remove that package and
b) remove any template files that may be causing problems?

Or should just adding the exclusion be enough?

Thanks!

You only need to add it to the exclusion/pkgskip list.

Very cool. Thanks.

I am trying all of this on one server and the rebuildnamedconf is not helping. /etc/named.conf is totally emtpy

Any ideas on hwo to rebuild named.conf?

Thanks
