Re: [qmailtoaster] lot of cname lookup failed

2017-05-04 Thread Eric Broch 

Here's a link that shows how to do a downgrade with RPM. I'd test it first.

I've used yum downgrade on my servers and it worked fine, but I think 
you need a repo set up.

sorry for the late response

i have implemented on my test server and it works fine, but the real test would 
be when i implement it on production since the issue is a random one.

if need to go back to the older version incase i face any problems then how do 
i do that ?

if i try to recompile the older version it does not allow me to downgrade.

Rajesh,

Do you want to go through the patch procedure our simply use the RPM
I've provided at the below link? It would be a simple matter of doing a
'yum --enablerepo=qmt-testing update' if you have the QMT repos set up
for YUM. I've already installed this on my CentOS 6 box.

You could also download the SRPM

and build it on your own machine. Commands are as follows provided you
have a build environment:

# cd ~/rpmbuild/SRPMS

# wget
ftp://ftp.qmailtoaster.com/pub/repo/qmt/CentOS/6/testing/SRPMS/qmail-1.03-1.qt.src.rpm

# rpmbuild --rebuild --define "dist .qt.el6" qmail-1.03-1.qt.src.rpm

# rpm -Uvh ~/rpmbuild/RPMS/x86_64/qmail-1.03-1.qt.el6.x86_64.rpm

Hi Rajesh,

If so, I've uploaded a qmail update

to the QMT/CentOS 6 repository that incorporates the DNS patch you

It has not been tested. If you do install it and something goes wrong,
it most likely won't, you can always downgrade which I've been doing

Re: [qmailtoaster] lot of cname lookup failed

Also, it might be helpful to have only one DNS server listed in your 
resolv.conf file...maybe to segregate the offending server if it is 
indeed a DNS server issue. Maybe that would help pre-upgrade.

hi eric

we are receiving a lot of cname lookup failed.

this happens on a random basis on all our qmailtoaster servers.

our resolv.conf contains

127.0.0.1
8.8.8.8
8.8.4.4

we use bind locally within the mail server and google's dns which is also set 
as cache records and allow lookups from local ips only.

Had a quick question

there are supposedly two different patches.

https://www.mail-archive.com/qmailtoaster-list@qmailtoaster.com/msg35981.html

is qmailtoaster on whitehorse patched with both these two patches related to 
dns.?

Hi Rajesh,

The first patch (Big DNS) is included in QMT, but the T_ANY to T_CNAME 
is not.
