Hi Guys,
Just a question RE setting up the DNS zone record correctly for a mail
server.
I have a couple of setups which work but have just copied one and I'm
getting the following response.
<j.gilb...@watercooledsurf.com>: Host or domain name not found. Name service
error for name=watercooledsurf.com type=A: Host found but no data record of
requested type
One zone I have is set up as
; Zone: grosvenorchambers.co.uk
; Generated: Fri Jan 23 14:53:53 2009
;
@ IN SOA ns0.dnsmaster.net.
hostmaster.dnsmaster.net. (
2008110301 43200 1800 604000 86400 )
IN NS ns1.dnsmaster.net.
IN NS ns2.dnsmaster.net.
IN NS ns3.dnsmaster.net.
grosvenorchambers.co.uk. IN MX 10 mail2.freewayprojects.com.
ftp IN CNAME ftp2.freewayprojects.com.
mail IN CNAME mail2.freewayprojects.com.
smtp IN CNAME smtp2.freewayprojects.com.
webmail IN CNAME webmail2.freewayprojects.com.
www IN CNAME web2.freewayprojects.com.
And another is set up as
; Zone: firetecworld.com

@ IN SOA ns0.dnsmaster.net.
hostmaster.dnsmaster.net. (
2008081001 43200 1800 604800 86400 )
IN NS ns1.dnsmaster.net.
IN NS ns2.dnsmaster.net.
IN NS ns3.dnsmaster.net.
IN MX 10 mail.firetecworld.com.
IN A 212.84.168.98
ftp IN CNAME ftp2.freewayprojects.com.
mail IN CNAME mail2.freewayprojects.com.
smtp IN CNAME smtp2.freewayprojects.com.
webmail IN CNAME webmail2.freewayprojects.com.
www IN CNAME web2.freewayprojects.com.
In both cases I am trying to keep them set up so that if the main server
fails I can then repoint mail2.freewayprojects.com,
smtp2.freewayprojects.com, web2.freewayprojects.com etc to the
secondary/backup server and the service will continue. I.e. I won't
have to change all the clients DNS records - just the
*2.freewayprojects.com IP addresses.
I tried initially to copy the first one.
What is the best/canonical way for setting up DNS reocrds?
We have www happily CNAME'd to the web server address. Similarly for
mail, ftp, smtp, webmail etc. The mail should just need an MX record.
Does the mail need an 'A' record of some sort?
Thanks,
Kevin Bailey
