Hi,
I came across a very weird DNS issue. At this stage I am kind of out of options. I hope there is someone who can help.
So what is the situation then? Well, I just setup my VPS server. I have 3 domains running on this server. It is running OpenSuse 11.1Plesk 9.2.1.
I installed and transported my old websites to the new server, configurated it using the plesk control panel and everything worked fine.
At my domainregistrars the A records are pointing to my server. All pings and trace routes of the domains point to my server; the are set up correctly.
There was a minor issue. The webmail client.
I found out there was no webmail client installed. So what I did was to install the atmail webmail client by using the commandline interface. I used wget to get the psa-atmail files from autoinstall files at plesk and used the RPM --install command to install the atmail.
This all seem to work fine. I went back to the plesk admin panel and selected atmail as default webmail client (
Home>Domains>problem.com>Mail Accounts Under the Domain problem.com>mail settings>webmail). Please note that I had not installed Horde.
I now noticed plesk created two extra DNS records:
*.webmail.problem.com. CNAME problem.com.
webmail.problem.com. CNAME problem.com
The full DNS record in plesk looks like:
123.456.789.001 / 24 PTR problem.com.
ftp.problem.com. CNAME problem.com.
mail.problem.com. A 123.456.789.001
ns.problem.com. A 123.456.789.001
problem.com. NS ns.problem.com.
problem.com. A 123.456.789.001
problem.com. MX (10) mail.problem.com.
problem.com. TXT v=spf1 +a +mx -all
Weird thing is, this DNS config differs from the other domains. I noticed this after I found out that my webmail.problem.com was not accessable and on a other domain on the same webserver (webmail.noproblem.com) it was available. After looking into the DNS record, I found out that the noproblem.com domain was using webmail.noproblem.com. A 123.456.789.001
instead of webmail.problem.com CNAME problem.com.
I have no idea why. Since the webmail client was not working I decided to change the problem DNS record (webmail.problem.com CNAME problem.com > webmail.problem.com A 123.456.789.000).
I figured, let’s get this webmail client running later on, and I went adding some products for my webshop. After some time I got no response from my problem.com domain. Did the pings and traceroutes, still pointing to the correct IP address. I was stunned, what is going on?
When I want to visit the website I get a DNS error, website can not be found. Funny enough it can find the ftp.domain.com but not the www.domain.com or domain.com. The DNS records in the zone file is similar to the other two domains who are running correctly.
(also see post : DNS server with SUSE Linux 10.0 - openSUSE for setting up the zone files.
What I have noticed is that in my Plesk control panel when I click “Click to preview the website in webbrowser” at the icon on the right at parallel plesk HOME > DOMAINS page they all point to domain.com without the www. This also counts for the domain with the problem, only thing is that this particular domain with the problem, somehow redirects to www.domain.com. This does not count for the other domains.
Can anyone please help? Hope my problem is clear.
