    <p>I have an EC2 instance (Amazon AMI) on AWS and I have a purchased a domaine name on Gandi.net. Let's imagine my domain name is "teaorcoffee.com".</p> <p>On Gandi, I have set up a sub-domain name "dev" to delegate DNS to my EC2 instance. Here is the configuration in the zone file on Gandi :</p> <blockquote> <p>dev 10800 IN NS ec2-22-222-222-22.eu-west-1.compute.amazonaws.com.</p> </blockquote> <p>I would like to configure sub-domain of "dev.teaorcoffee.com" on my EC2 instance, like "sql.dev.teaorcoffee.com".</p> <p>I am trying to do that with :</p> <ul> <li>the "bind" util</li> <li>the file "named.conf.local" wich is included in the file "named.conf"</li> <li>and a "dev.teaorcoffee.com" zone file</li> </ul> <p>but without success.</p> <p>Here is the "named.conf.local" file :</p> <blockquote> <p>zone "dev.teaorcoffee.com" IN { type master; file "/var/named/dev.teaorcoffee.com"; allow-update { none; }; };</p> </blockquote> <p>Here is the "dev.teaorcoffee.com" zone file :</p> <blockquote> <p>$TTL 60 @ IN SOA master.dev.teaorcoffee.com. support.teaorcoffee.com. ( 2013030300 60 60 60 38400 ) dev.teaorcoffee.com. IN NS master master.dev.teaorcoffee.com. IN A 127.0.0.1 sql IN CNAME master</p> </blockquote> <p>I can restart the dns without any error with the command :</p> <blockquote> <p>sudo /etc/init.d/named restart</p> </blockquote> <p>But when I am trying to do a nslookup on "dev.teaorcoffee.com" and its sub-domain, I get the following error :</p> <blockquote> <p>nslookup dev.teaorcoffee.com Server: 127.0.0.1 Address: 127.0.0.1#53</p> <p><em>*</em> Can't find dev.teaorcoffee.com: No answer</p> </blockquote> <p>What can I change to make it work ?</p> <p>Thanks in advance for any help.</p>

    1. COWhat do you expect "nslookup dev.teaorcoffee.com" to find, considering that you haven't declared any "A" records for "dev.teaorcoffee.com"? What if you try "sql.dev.teaorcoffee.com" ... also, use `dig` instead of nslookup for more informative messages.

    2. COThank you for your remark. I have made so many changes to make it work, that I have forgotten this instruction. So, I have added this line to my zone file : `@ IN A 127.0.0.1`. Then, I have executed the `dig` command instead of `nslookup`. It seems to work without any problem. But, I still can't `ping dev.teaorcoffee.com` or any sub-domain outside of my EC2 instance.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
