RE: problem with notifies
The CentOS stuff is built from RHEL sources so the basic repositories wouldn't have a newer BIND base package than RHEL. However, as noted previously the RHEL provided package includes backports of later BIND base versions for bug and security fixes. Of course you can always install a later BIND by getting the source and configuring/compiling your own. On RHEL one might resist this since RedHat's support is for the one they provide but on CentOS there's no support so no reason not to go ahead and move to the later version of BIND. I'd recommend you uninstall the existing BIND rpms before doing that though so that a future yum update doesn't overwrite your build. (Of course you'd also want to save your named.conf, zone files etc... before doing such a removal so they don't get deleted.) -Original Message- From: bind-users-bounces+jlightner=water@lists.isc.org [mailto:bind-users-bounces+jlightner=water@lists.isc.org] On Behalf Of Matus UHLAR - fantomas Sent: Thursday, April 01, 2010 6:53 AM To: bind-users@lists.isc.org Subject: Re: problem with notifies On 30.03.10 23:23, fddi wrote: > CentOS 5.4 has bind version 9.3.6 and that's it. > Before I had a CentOS 4.0 which was still using 9.2.x oh.

It's only "bad practice" if you are not using other methods to prevent spoofing attacks succeeding.

It's really not the job of a load balancer or server to force clients to use good security practices. I suspect this is actually a bug, but the vendor is using the security value of it as an excuse to lower its priority. -- Barry Margolin, bar...@alum.mit.edu Arlington, MA *** PLEASE don't copy me on replies, I'll read them in the group *** ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
