Re: Performance Tuning RHEL 5 and Bind
Hi, Kevin Darcy k...@chrysler.com writes: Are these queries mostly for names in an Active Directory domain? The default for Active Directory is for *every* Domain Controller to register NS records at the apex of the AD domain. Pretty soon, for any reasonably-sized AD infrastructure, all of those NSes cause *all* queries for *any* name in the domain to trigger a TCP retry (because the Answer + Authority Sections overflow 512 bytes), if EDNS0 is not in effect. I sat down with our AD folks a few years ago and impressed upon them how important it is to be selective about which Domain Controllers are registered at the apex. They appreciated the negative consequences of being awash in TCP retries, and it's been managed for some time now (at least for our *main* AD domain; don't get me started on the business partner that still has 92 NS records at the apex of their AD domain. Sigh) good point. Increasing the EDNS0 UDP size might also be an option (default is 1280 for Windows DNS) - http://technet.microsoft.com/en-us/library/cc783893%28v=ws.10%29.aspx It is possible to tell some less critical DC to not register themself in DNS: http://support.microsoft.com/kb/198767 and http://technet.microsoft.com/en-us/library/cc782946%28v=ws.10%29.aspx -- Carsten ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
Upgrade Bind documentation
Does anyone have any advice or perhaps documentation for upgrading Bind? I currently have two AIX servers running as Master/Slave. I need to upgrade from v9.8.1-P1 to v9.8.6. I will need to document an implementation plan for change control and was hoping someone else may have something they can share. I've browsed the ISC web site looking for release notes, install/compile instructions, migration plans, etc without much success. ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

Here are some links for you: http://ftp.isc.org/isc/bind9/9.8.6/RELEASE-NOTES-BIND-9.8.6.txt https://kb.isc.org/article/AA-01054/81/BIND-9.8.6-Release-Notes.html The brief installation directions are in the tarballs' README file. Our operating specific hints are at https://kb.isc.org/category/48/0/10/Software-Products/BIND9/FAQs/Operating-System-Specific/ but none for AIX. We don't have a migration guide specific for 9.8 series (we do have a migration details from 8 to 9). I'd expect that all the configurations from 9.8.1 through 9.8.6 are compatible. The 9.8.6 reference is at http://ftp.isc.org/isc/bind9/9.8.6/doc/arm/Bv9ARM.html (and in the tarball). I am working on a chart listing the major features introduces and any incompatible changes to be aware of for all of our releases. But it is not ready yet. Jeremy C.
