<style> </style> <h2>Custom DNS</h2> <p class="text-warning">This is an advanced configuration page.</p> <p>It is possible to set custom DNS records on domains hosted here.</p> <h3>Using a Secondary Nameserver</h3> <p>If your TLD requires you to have two separate nameservers, you can either set up a secondary (aka “slave”) nameserver or, alternatively, set up <a href="#" onclick="return show_panel('external_dns')">external DNS</a> and ignore the DNS server on this box. If you choose to use a seconday/slave nameserver, you must find a seconday/slave nameserver service provider. Your domain name registrar or virtual cloud provider may provide this service for you. Once you set up the seconday/slave nameserver service, enter the hostname of <em>their</em> secondary nameserver:</p> <form class="form-horizontal" role="form" onsubmit="do_set_secondary_dns(); return false;"> <div class="form-group"> <label for="secondarydnsHostname" class="col-sm-1 control-label">Hostname</label> <div class="col-sm-10"> <input type="text" class="form-control" id="secondarydnsHostname" placeholder="ns1.cloudprovider.com"> </div> </div> <div class="form-group"> <div class="col-sm-offset-1 col-sm-11"> <button type="submit" class="btn btn-primary">Update</button> </div> </div> <div id="secondarydns-clear-instructions" class="form-group" style="display: none"> <div class="col-sm-offset-1 col-sm-11"> <p class="small">Clear the input field above and click Update to use this machine itself as secondary DNS, which is the default/normal setup.</p> </div> </div> </form> <h3>Custom DNS API</h3> <p>Use your box’s DNS API to set custom DNS records on domains hosted here. For instance, you can create your own dynamic DNS service.</p> <p>Send a POST request like this:</p> <pre>curl -d "" --user {email}:{password} https://{{hostname}}/admin/dns/set/<b>qname</b>[/<b>rtype</b>[/<b>value</b>]]</pre> <h4>HTTP POST parameters</h4> <table class="table"> <thead><th>Parameter</th> <th>Value</th></thead> <tr><td>email</td> <td>The email address of any administrative user here.</td></tr> <tr><td>password</td> <td>That user’s password.</td></tr> <tr><td>qname</td> <td>The fully qualified domain name for the record you are trying to set.</td></tr> <tr><td>rtype</td> <td>The resource type. <code>A</code> if omitted. Possible values: <code>A</code> (an IPv4 address), <code>AAAA</code> (an IPv6 address), <code>TXT</code> (a text string), or <code>CNAME</code> (an alias, which is a fully qualified domain name).</td></tr> <tr><td>value</td> <td>The new record’s value. If omitted, the IPv4 address of the remote host is used. This is handy for dynamic DNS! To delete a record, use “__delete__”.</td></tr> </table> <p style="margin-top: 1em">Note that <code>-d ""</code> is merely to ensure curl sends a POST request. You do not need to put anything inside the quotes. You can also pass the value using typical form encoding in the POST body.</p> <p>Strict <a href="http://tools.ietf.org/html/rfc4408">SPF</a> and <a href="https://datatracker.ietf.org/doc/draft-kucherawy-dmarc-base/?include_text=1">DMARC</a> records will be added to all custom domains unless you override them.</p> <h4>Examples:</h4> <pre># sets laptop.mydomain.com to point to the IP address of the machine you are executing curl on curl -d "" --user me@mydomain.com:###### https://{{hostname}}/admin/dns/set/laptop.mydomain.com # sets an alias curl -d "" --user me@mydomain.com:###### https://{{hostname}}/admin/dns/set/foo.mydomain.com/cname/bar.mydomain.com # clears the alias curl -d "" --user me@mydomain.com:###### https://{{hostname}}/admin/dns/set/bar.mydomain.com/cname/__delete__ # sets a TXT record using the alternate value syntax curl -d "value=something%20here" --user me@mydomain.com:###### https://{{hostname}}/admin/dns/set/foo.mydomain.com/txt </pre> <script> function show_custom_dns() { api( "/dns/secondary-nameserver", "GET", { }, function(data) { $('#secondarydnsHostname').val(data.hostname ? data.hostname : ''); $('#secondarydns-clear-instructions').toggle(data.hostname != null); }); } function do_set_secondary_dns() { api( "/dns/secondary-nameserver", "POST", { hostname: $('#secondarydnsHostname').val() }, function(data) { if (data == "") return; // nothing updated show_modal_error("Secondary DNS", $("<pre/>").text(data)); $('#secondarydns-clear-instructions').slideDown(); }, function(err) { show_modal_error("Secondary DNS", $("<pre/>").text(err)); }); } </script>
