dig -x
-
I am setting up my hostname like this:
127.0.0.1 localhost.localdomain localhost
127.0.1.1 mail.eclecticmedia.co.uk mail
[my IP]***.**.***.*** mail.eclecticmedia.co.uk eclecticmedia.co.ukAnd then in my /etc/hostname I put:
mail
This resolves fine, except that when I
dig -x [IP], it is not coming up, even after 48 hoursAny ideas?

hi Marcus, to be clear, what does this come up with:-
hostname -f
.. let me know, sounds like a small config issue which I had/changed in the scripts last week.

$ hostname -f
mail.eclecticmedia.co.uk$ dig -x ***.**.***.**

ok, try this (for "mail.eclecticmedia.co.uk"). backup the two files first, just in case .. then ..
#
#
in /etc/hosts:-
#
127.0.0.1 localhost 127.0.1.1 mail.eclecticmedia.co.uk mail ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts#
#
and in /etc/hostname:-
#
mail.eclecticmedia.co.uk#
#
you'll need a system reboot to see the results, again using the dig or hostname commands.Posted 10 months ago # -
Hi Olly, I did what you suggested yesterday, but it won't resolve.
Same results as before

Hi Marcus,
Sorry, I had to replicate this. I think the issue is most likely your "reverse DNS" setting. (Please tell me you didn't set this up!)
Take a look at http://vpsbible.com/email/setup-postfix-email/ for the detail but, basically, you need:-
* an A record for mail.eclecticmedia.co.uk (so that's really an A record in the eclecticmedia.co.uk just for "mail", pointing to the IP with a default TTL, set via the DNS Manager)
* wait for the a record to propagate (about 15 minutes, half an hour max). Then, the RDNS itself is set by "Perform a forward lookup" in the Reverse DNS setting of the Remote Access tab of your Linode manager. Tap in "mail.eclecticmedia.co.uk". The query should come back saying the record is found and are you sure. Basically, say "Yes".
You may be prompted to reboot.
Then "dig -x [IP]" again.
Otherwise, your "/etc/hostname" should say "mail.eclecticmedia.co.uk", not just mail. Set that before the reboot.
Lemme know.
(Out of curiosity, did you set up via a script? Which one? I'll check that the above info is included.)

Hi Guv,
Sorry for the hiatus. I do appreciate your replicating all this.
Where is the reverse DNS function in the present linode dash?
Cheers
