similar to: auth: Warning: DNS lookup took 1.550 s

Thanks for your comments. I understand as DNS uses UDP that there could be some DNS queries which might get lost if the CPU or network is too busy but the thing is that this server is not so busy really. It has 2 cores with 4 GB of RAM and the CPU averages to 2% usage. The network averages to 1 Mbit/s traffic and there are around 600-700 processes running for 1100 mailboxes. Note here that this

Hello, I am running a dovecot and proxy server on two different virtual machines and on the dovecot proxy server I see around 5-6 times per day the following warning: Feb 03 16:15:12 auth: Warning: proxy(email at domain.com,xxx.xxx.xxx.xxx,<ABC123456789>): DNS lookup for mailboxserver.domain.com took 1.550 s I do not really understand how from time to time DNS queries are slow, I tried

how do you come to the conclusion that it matters how busy "this server is"? jesus christ you are asking *remote servers* for their answers and the request as well the answer passes different routers, ISP's and likely a *chain of forwarders* until you don't recursion at your own and even if you do you have no control how overloaded one of the networks between you and the

As another poster has commented, a slow DNS response may not be anything related to your setup, but caused by upstream DNS service. Slow DNS response or timeouts is not

To cite from www.xiph.org (the author's name of this text was not available on the page): The Ogg project began with a few-weekend-attempt at a simple audio compression package as part of a larger project in 1993. At the time, the software was called 'Squish'. The project and the general problem of music compression became a personal fascination, and Squish took on a life of its own

The scenario: I have two Samba servers on my network. One, running v3.0.37, is on my main server, a Solaris 10 x86 box. The other, just updated from 3.0.37 to 3.4.5 in the hope of solving this problem, is on my workstation, a Gentoo Linux box. The Linux Samba server shares only [homes]. The Solaris Samba server shares [homes] and four other shares. Unix UIDs are synchromized betwene the

I am attempting to remove an element in the :afterFinish callback of the "Squish" effect. This is what my call looks like. <%= link_to_remote ("X", :url => { :action => "deleteIt", :id => wc_line.attributes[''id''], :exercise_id => wc_line.attributes[''exercise_id''] },

While SVCB/HTTPS provides a better solution for the browsing use case, I see other use cases where ALIAS/ANAME would be ideal, notably in apex RRs. So while fostering SVCB/HTTPS deployment is a good thing, I wouldn?t mind name server software implementing ALIAS. Including NSD, but I reckon it?s much more challenging to do due to NSD architecture than it was to implement it in PowerDNS. But if

Hi Christof! AFAIK, PowerDNS is the only open source name server that supports ALIAS. There was an idea to standardize ALIAS as "ANAME" (https://datatracker.ietf.org/doc/draft-ietf-dnsop-aname/), but the idea was dropped in favor of SVCB/HTTPS record https://datatracker.ietf.org/doc/rfc9460/. So now we have to wait until all Browser vendors implement SVCB/HTTPS. Regards Klaus PS: If

PowerDNS supports CAA records beginning with version 4.0, but the pdns package in EPEL for most recent centos versions is stuck at around version 3.4 (3.4.11 is what I have). Do I have no other choice but to manually compile and maintain my own pdns installation? I prefer to avoid this but I need up-to-date features. Perhaps there is a PowerDNS specific work-around? Maybe the EPEL
