+Version 5.0 [2019-01-30]
+
+ Added support for DNSSEC. See section 8 of README.
+
+ It turned out that configurability of directory names (e.g., HASHDIR)
+ was incomplete and it made all scripts unnecessarily complicated.
+ We replaced the configuration variables by hard-coded names equal
+ to the previous default settings which hopefully nobody ever needed
+ to change.
+
+ Also, ROOTHINT() became obsolete as BIND packages now regularly come
+ with a well updated root hint file. Please set up the root hints in
+ the master bind configuration file before you include named.conf
+ generated by NSC.

NSC is a set of shell and M4 scripts for easy maintenance of DNS zone files
for all your hosts, handling of classless reverse delegations and support for IPv6
(AAAA and PTR in ip6.arpa, not A6 and DNAME which seem to be dying out).
- NSC requires GNU m4, a POSIX-compatible shell and the `md5sum' utility (which
-is present for examile in GNU coreutils). Some of the extra utilities require
-Perl 5. I've tested everything on Linux (Debian Squeeze), but the whole package
-should run on other unices as well.

consistency checker. It's a simple utility written in Perl with help of the
DNS module and it should be able to detect all common errors in DNS setup

1. Directory structure
m4/ - M4 scripts (used by the commands)
zone/ - primary zone files
bak/ - backups of zones we serve as a secondary NS for
- hash/ - hashes of zone files used for detection of changes
ver/ - version files where NSC remembers version
numbers of the primary zones
+ tmp/ - temporary files
+ hash/ - hashes of zone files used for detection of changes
+ dss/<domain> - DNSSEC DS records
+ keys/<domain>/ - DNSSEC keys
+ khash/ - hashes of DNSSEC keys used for detection of changes
How are different files created:
- You create everything in cf/.
- Then you run bin/nsconfig.
+ - If you want to use DNSSEC, create keys (see section 8)
- Makefile and named.conf gets created according to cf/domains.
- You run make.
- The Makefile creates primary zone files in zone/ and version files
You can also use the REV macro explicitly, which can be handy
for example in SECONDARY declarations.
-ROOTHINT()
- Insert a definition of hints for reaching root servers into named.conf.
- This is necessary if you want your DNS server to resolve foreign
- domains; otherwise, it will only give out authoritative answers
- for locally defined zones and forward queries. The location of the
- file with the hints can be set by the ROOTCACHE directive (see below).
-
FORWARDED(zone, ip...)
Define a forwarding zone. All queries are forwarded to the
specified name servers.
MAKEFILE(...)
Insert user data to Makefile.
+DNSSEC(`declarations...')
+ Request DNSSEC signing for all zones declared within the block.
+
+DSFOR(zone)
+ Declare dependency of the previous PRIMARY/REVERSE domain on DS
+ records for the given zone configured in dss/*.
+
3. The Domain Files
~~~~~~~~~~~~~~~~~~~
ADDR(addr...)
Specify addresses for the current host. In the normal mode, it
- creates A records, in the reverse mode, PTR records.
+ creates A/AAAA records, in the reverse mode, PTR records.
H(host, addr...)
A shortcut for H(host) ADDR(addr...) -- in many cases everything
Specify a list of name server names for the current domain
(started by either a SOA or D declaration). Generates NS records.
+DS()
+DS(dsset)
+ Include DS records for the current sub-domain. With no arguments,
+ they are loaded from dss/<sub-domain>. If the name of the sub-domain
+ does not match the name of the DSset (as it frequently happens with
+ reverse zones), you can specify the DSset name explicitly.
+
MX(mx...)
Specify a list of mail exchangers for the current host or domain.
Each mail exchanger should be preceded by a priority. Generates
The following variables are available:
NAMED_RESTART_CMD Shell command for restarting the name server daemon
- (default: ndc restart)
+ (default: rndc reload)
-ROOT Root directory of the whole package (default: /etc/named)
CFDIR Directory with config files (default: cf)
-ZONEDIR Directory with zone files (default: zone)
-BAKDIR Directory with backup files (default: bak)
-HASHDIR Directory with zone hashes (default: hash)
-VERSDIR Directory with version files (default: var)
-ROOTCACHE File with the cache of root name servers

MAINTNAME Domain maintainer name (default: root@NSNAME)
+KEYGEN_OPTIONS Extra options given to dnssec-keygen

-8. Interaction with M4
+8. DNSSEC support
+~~~~~~~~~~~~~~~~~
+NSC knows the basics of DNSSEC. It does not handle key management (you need to
+schedule generation and retirement of your keys by other means), but once the
+keys are in place, it uses them for signing zones.
+
+=== Key management ===
+
+Keys live in keys/<zone>/*.(key|private) and they are stored in the usual BIND
+format. To generate a zone-signing key, you can use the following command after
+writing at least rudimentary cf/<zone>:
+
+ bin/key-gen <zone>
+
+If you want a key-signing key, use:
+
+ bin/key-gen <zone> -f KSK
+
+(Generally, you can add arbitrary arguments for BIND's dnssec-keygen. Default
+keygen options can be set in cf/config, see section 4.)
+
+To detect key changes, NSC keeps a hash of all keys for each domain.
+If you edit the keys manually (e.g., to delete a key), you need to recalculate
+the hash by:
+
+ bin/key-update <zone>
+
+(or without a zone to update all hashes).
+
+=== Domain signing ===
+
+All domains whose declarations in cf/domains are wrapped by DNSSEC(`...')
+are automatically signed using all set up keys. If you specify key validity
+period when generating the key, it is respected, but the domains are not
+re-signed automatically when a key becomes valid / ceases to be. If you
+want to modify dnssec-signzone arguments, you can do so in cf/config.
+
+Beware that all signatures have a limited lifetime (even if the keys do not
+expire). The default lifetime is 365 days, so you need to re-sign your zones
+at least once in a year. The recommended solution is to set up a cron job,
+which touches keys/resign-stamp. A change of timestamp of this file forces
+a re-sign on the next run of make.
+
+=== Subdomains ===
+
+If you want to delegate a signed sub-domain, you need to include DS records
+in the parent zone. Add a DS() macro after declaration of the sub-domain
+in the parent. It loads DS records from dss/<child>.
+
+If the sub-domain is also maintained by NSC, you can generate the DS record
+set automatically by:
+
+ bin/key-delegate <zone>
+
+=== Reverse zones ===
+
+Unlike primary/secondary zones, reverse zones have file names which differ
+from the full domain name. In such cases, keys are named after the file name
+and NSC constructs the full name whenever necessary.
+
+There is one exception where automatic construction is not available:
+delegation of sub-domain keys. In such cases, you need to pass the file
+name of the sub-zone to the DS macro.
+
+
+9. Interaction with M4
~~~~~~~~~~~~~~~~~~~~~~
All config files are fully-fledged M4 scripts, so you can use any M4 features
you need, the most helpful one being definition of your own macros by
freebsd: don't use `-f' in hostname
+
+- Update or delete nsc.lsm
+- do we still need root.cache?
