Bind reload zone files

Dynamic update is, of course, another way to update zone data without restarting the name server; see Section 5. Section 2. Previous page. Table of content. Next page. Authors: Cricket Liu.

I want to add records to the zone,, not adding a new zone Neven — Nidal. Once again, we've chosen in our example to use a localhost address. You'll need to be familiar with AAAA records if you expect to set up your own mailserver—Google stopped being willing to talk to mailservers without fully working IPv6 DNS a few years ago!

CNAME records are handy, but they're a bit funky. If you try to set MX mail. CNAME example. If you have access to Linux, Mac, or Windows Subsystem for Linux, by far the best command line tool is dig. Using dig is as simple as specifying a server to query, the record type you want to look for, and the FQDN it should be associated with. In the example above, we asked the DNS server at In addition to the answers we wanted, we got a ton of diagnostic information—the DNS server we queried did not return an ERROR when queried, it says it is authoritative for the domain in question, and so forth.

If you don't have access to dig , you can generally get by with nslookup. Most commonly, this is a semi-cursed workaround for users sitting at a Windows box without access to Windows Subsystem for Linux, cygwin, or some other way to gain access to more advanced tools than the Windows CLI provides.

Here's a sample session:. By setting server You don't have to specify this; if you don't, nslookup will use whatever the default DNS resolver on your machine would. After optionally setting the server , you can just type a bare hostname into nslookup 's interactive prompt, and it will return any A or AAAA records it can find for that hostname.

If you want to query the remote server for a different type of record, you'll need to use a set type command. It works, and you get your answers The proper way to get out of nslookup 's interactive mode is the command exit. Hopefully, you never need to look up information about a top-level domain also named exit —or if you do, you'll have a better tool available than nslookup when you do. Hopefully, you picked up something valuable today about how DNS works and how its information is stored.

Although the storage format may change somewhat from server to server—such as an Active Directory domain controller literally storing zones inside Active Directory itself, rather than a plain text file—the record types are universal, and the formatting at least near-universal. In addition to the sheer joy of learning how to manage these things, you may also find you value the ability to set your TTLs absurdly short—most managed DNS servers won't allow a TTL of less than 30m, and most will attempt to default you to TTLs of up to a week.

This is fine and dandy for a DNS zone, which is already properly set up and doesn't need changing Each certificate and key file will have a suffix, just before the file extension, indicating the type of key the file is for. If you are only using a single key type, or want to omit the suffix from one key type, set it to an empty string. Note that if using multiple key types the suffix must be unique or files will be overridden.

All output file names can be overridden using standard Python format strings. The tool will process the source zone file and output a zone file ready for use by the DNS server.

It is best to keep the source zone files in a different directory than the DNS server uses for its zone files. The script reload-zone. The file path is will be searched for relative to the path of the file containing the include command, the primary zone file, or the configured include directory. Include files can include additional files. The file path may contain standard glob patterns, all files matching the pattern will be included.

Variables defined in an include file are available for use in the file containing the include command at any point after the include.

Additional named arguments may follow the include file path, these will define local variables available only inside the included file or files included by that file.

Local variables will override normal variables with the same name. The tool can also automatically generate the several kinds of resource records.

The format for these records is:. Optional arguments my be omitted, however if all arguments are omitted, at least one colon must follow the record type to distinguish it from a variable.
