Named not starting after yum update

Again, if you read the thread you will see that we are still discussing security. I am not going to say it again.
 
Hello,

I'm not sure that the localhost.zone and the named.local have anything to do with caching nameservers. If you check them, all they do is make:

localhost.zone: localhost resolve to 127.0.0.1
named.local: 127.0.0.1 resolve to localhost

nothing too magical there.

I have no clue why they're being deleted either... check for /var/named/localhost.zone.rpmsave in case the rpm decided they don't belong there.. not too sure.

Regarding caching namesrevers, yes, bind is a caching nameserver by default. However, as of a few months ago, we include this line
Code: 
allow-recursion { localnets; };
(relating to this guide) which says that only local lookups are allowed to use the caching bits. External people can only do lookups on non-cached domains (domains that live on your DA box)

I don't believe there is any security issue... the only issue is why the 2 files are being deleted or renamed by the yum update, which would still be a mystery.

Sorry, John, and everyone ... I misread the specific files in question :(. I've edited my post.

Hi all,

Read this post carefully before I did an update on my servers. I got 3 of them, one with only an admin domain on it and 2 with lots of domains. I first tried the Bind update (yum update bind*) on my "Testserver" the one with only the admin domain. Backupped the whole /var/named/ directory and did the RPM update (from 9.3.3rc2 to 9.3.4-P1). Everything went fine and the update did not touch my named.conf OR the localhost.zone OR the named.local file.

I thought everything was ok and went ahead with the update on my other servers. There those 2 files (localhost.zone and named.local) were deleted.....So named could not start. I copied the info from my Testserver on the other two servers and named is up and running again.....But is there an example file of localhost.zone and named.local? Are these 2 files server dedicated or is there no diffirence in settings in these files?

Only diffirence between these 3 servers is the hardware manufacturer. All Centos 5.

Tnx in advance.
