Full Discussion: BIND9 CNAME to External Domain
Top Forums UNIX for Dummies Questions & Answers BIND9 CNAME to External Domain Post 302918826 by DGPickett on Thursday 25th of September 2014 05:20:12 PM
Old 09-25-2014
If you are not authoritative for a domain, you have no files for that domain, and normally no records for its hosts in any zone (unless you need to intercept some queries behind firewalls to point them to internal IPs, where a full.dotted.name. record is used). But you could be a slave server for it, if that makes sense in the reliability and latency models.

CNAMEs are just aliases, since in a well ordered world, the A lookup for a.b.c as 1.2.3.4 is the exact reverse of the PTR lookup, and any other names must be by CNAME. If you move the server, the CNAMEs must have the new IP and reside on the authoritative master. Ditto for the A and PTR records. This might be multiple servers, but there is only one authoritative master for each.

NAME

       asadmin-start-domain, start-domain - starts the given domain

SYNOPSIS

       start-domain [--domaindir install_dir/domains] [--terse=false] [--echo=false] [--verbose=false] [--debug] [domain_name]

       start-domain  starts the specified domain. If there is only one domain in the default domain directory (install_dir/domains), then no oper-
       and is required to start the domain. However, if there is more than one domain, the domain operand must be specified. This command can only
       be run locally.

OPTIONS

       --domaindir	       directory where the domain is to be started. If specified, path must be accessible in the filesystem. If not speci-
			       fied, the domain is started in the default install_dir/domains directory.

       --terse		       indicates that any output data must be very concise, typically avoiding human-friendly sentences and favoring well-
			       formatted data for consumption by a script. Default is false.

       --echo		       setting to true will echo the command line statement on the standard output. Default is false.

       --verbose	       by  default this flag is set to false. If set to true, detailed server startup output is displayed. Press CTRL-C to
			       kill the server. Press CTRL- to print a thread dump.

       --debug		       by default this flag is set to false. If set to true, the server is started in debug mode and prints the JPDA  port
			       on the console.

OPERANDS

       domain_name	       name of the domain. Must be a unique name.

       Example 1: Using start-domain

       asadmin> start-domain sampleDomain
       Starting Domain sampleDomain, please wait.
       Domain sampleDomain started

       Where: the sampleDomain domain is started.
