caching-nameserver.noarch

[faris]

Can anyone enlighten me please?

I made the mistake or doing some updates on Cos4/Plesk the other night while half-asleep and without logging, and I'm wondering if I've done any damage.

Essentially I have removed caching-nameserver from a few of my personal VPSes. I *think* I did this because I saw errors like:

Code: Select all

When updating bind the other day.

No visible harm seems to have been done (I did backup named.conf before I removed caching-nameserver, and restored the conf file afterwards).

Bind is working. DNS is working. All seems to be working.

As I understand it, caching-namserver is basically a configuration change for bind that allows it to cache lookups it makes.

On a server I can see how this would be useful and reduce load when it comes to dnsrbl blacklists ... but nothing much else.

Anyway.... should I worry much about having removed this "package" (seems to be a script more than anything else)?

I can't seem to be able to restore it now that I've removed it. yum says there's no such package as caching-nameserver.

Plesk recommends not installing caching-nameserver (nor bind-chroot which causes problems with Plesk): http://kb.parallels.com/en/234

Ah!

I knew bind-chroot was a no-no. I think in my half-sleep I confused bind-chroot with caching-namesever which is why I removed it. Maybe subconsiously I knew caching-nameserver was also a no-no, though to be honest I can't remember coming accross it before now.

Thanks for putting my mind at rest. Much appreciated.
