Re: [qmailtoaster] DNS temporary failure if one DNS server dont work.

2011-02-14 Thread Martin Waschbüsch
Seeing as it does not work right now, I don't know where the servers are listed 
on his system. Clearly there must be some configuration issue.

But at the same time, IMHO it is the best solution to ensure there is a 
properly configured local DNS server.
Such a local DNS server has a config where you can list forwarding DNS servers 
and that is where his name servers should be configured.

Imagine resolv.conf lists the two outside DNS servers directly.
Let's assume that the first entry (will be queried first) is down.

Although the system tries to send 50 individual mails to 
some...@googlemail.com, the mail server will experience a timeout for the first 
name server and only then query the secondary server. All that happens 50 
times(!)
Now, if you have a working caching DNS server, as soon as the first timeout 
happened and the secondary DNS server was queried, the local server has the DNS 
entry stored and the remaining 49 messages do not encounter any timeout at all.

Hi,

says he is using?

Sounds like you have lookups configured incorrectly on the system.
When a message is sent, a MX lookup in DNS takes place during the smtp 
process. It will fail during this transaction, since the system cannot 
lookup remote MX records to determine where to send mail to.
Double check your lookup configuration on this host. I thought I read 
somewhere later in the thread that you have 127.0.0.1 listed in 
resolv.conf - this would lead me to assume you have a caching DNS server 
setup on this machine as well. If this is the case, for Bind, check your 
named.conf file to ensure your forwarders include more than just the one 
DNS server that goes down.

What you could try is this:

Have a local caching DNS server and that takes care of resolving to as 
many

'real' DNS servers as you like.
Doing so means that your DNS server (local) is ALWAYS on (unless the 
daemon

dies) and this problem won't occur again.

Re: [qmailtoaster] DNS temporary failure if one DNS server dont work.

Marek,
  What order are the dns servers in /etc/resolv.conf?
If they are the failing one on line one then reverse them.

Re: [qmailtoaster] DNS temporary failure if one DNS server dont work.

2011-02-13 Thread Randy Katz

1. Perhaps make the local dns the primary (first) listed in /etc/resolv.conf
2. Have nagios or another monitoring script notify you and / or restart 
the secondary dns server when it fails

3. Definitely find out why the second dns server keeps failing and fix it

Regards,
Randy
