NAME

       buildrealms - assist in building a DNSSEC-Tools realms environment

SYNOPSIS

	 buildrealms [options] <realmsfile> <command> <command-args>

DESCRIPTION

       buildrealms helps in setting up a realms environment for use by dtrealms.  buildrealms creates the required file hierarchies for each
       realm, it moves a realm's files to their appropriate place in the hierarchy, and it updates several files for the final destination.

       The realm hierarchies are built in a staging area, which will hold the files for all the realms.  These are rollrec files, keyrec files,
       key files, configuration files, log files, and anything else needed for by DNSSEC-Tools to manage key rollover.	After buildrealms creates
       these files, the user should check the files to ensure that they are correct.  The files and directories in the staging then must be
       manually moved to the final directory.  It is from this directory that dtrealms will manage the various realms.	If the final directory
       isn't specified (via an option), then the directory in which buildrealms was executed will be the final directory.

       buildrealms uses a realms file to control how it builds the realms environment.	This realm entries in this file have a hoard field, which
       is only used by buildrealms.  For each realm, this field's value is a directory which holds the files needed by that particular realm.
       After building that realm, buildrealms removes the hoard entry from that realm record.  After all the realms have been built, a copy of
       this realms file is moved into the staging area.

       There are two operations buildrealms currently provides.  These operations are in support of creating and maintaining a DNSSEC-Tools realms
       environment.  This documentation describes the operations individually.

   Realms Environment Creation
       The create command builds the whole realms environment.	The realm file hierarchies are built in the staging area.  After buildrealms
       creates these files, the user should check the files to ensure that they are correct.  The files and directories in the staging then must
       be manually moved to the final directory.  If the final directory isn't specified (via an option), then the directory in which buildrealms
       was executed will be the final directory.

       buildrealms takes the following actions when given the create command:

       o   A file hierarchy is created for each realm.

       o   A DNSSEC-Tools configuration file is put in each realm's hierarchy.	If the -config option is given, then the specified configuration
	   file will be copied to each realm.  If it isn't given, then each realm's hoard will be searched for a file whose name ends with .conf.
	   The first such file found will be used for that realm only.	If such a file is not found, then the system-wide DNSSEC-Tools
	   configuration file will be used for that realm.

       o   The realm's rollrec, keyrec, zone, and key files are moved into the hierarchy.  The rollrec file is named in the realms file.  The
	   keyrec and signed zone files are listed in the rollrec file.  The unsigned zone files and key files are listed in the keyrec file.

       o   A key archive is created for each realm's existing, expired keys.  The key archive is placed in the realm's state directory in the
	   staging area.  Archived keys, as listed in the keyrec files, are moved to this key archive.

       o   Paths in several files are adjusted for the new hierarchy and the realm's final destination.  These paths include archived keys in the
	   realm's keyrec files, the key archive and rollerd log files in the realm's DNSSEC-Tools configuration file, and key directories in the
	   keyrec files.

   Realms Hierarchy Creation
       The trees command builds the basic directory hierarchy for each realm in the staging area.  However, no other files or directories are
       copied or moved in to the staging area..

       The following directories are created for each realm:

       o   configuration directory - This holds the dnssec-tools directory.

       o   dnssec-tools directory - This will hold the DNSSEC-Tools configuration file.

       o   state directory - This will hold the realm's state information, including the key archive.

       o   realm directory - This will hold  the realm's rollrec file, the keyrec files, the zone files (signed and unsigned), and the key files.

PREPARING FOR EXECUTION

       In preparing a realms file and the realm hoards for buildrealms, there are several things that should be kept in mind.

       o   Use relative paths for the rollrec file and three directories in the realms file.

       o   All a realm's files should be stored in its hoard.  They do not have to be in a particular place in the directory, as long as the
	   rollrec and keyrec files are accurate.

       o   At the end of the creation process, the realms file will be copied into the top level of the staging area.

       o   After specific files (e.g., rollrecs, keyrecs, etc.) are moved into a realm's part of the staging area, the remaining files in the
	   hoard will be moved into the realm's realmdir part of the staging area.  The hierarchical organization of the remaining hoard files
	   will be preserved.

       o   The contents of a keyrec's archive directory in the realm's hoard, as defined by the archivedir field, will be moved to
	   <statedir>/key-archive in the staging area.

       o   The configuration file for a realm will be put in <configdir>/dnssec-tools/<conffile> in the staging area.  The actual name of the
	   configuration file (given here as <conffile>) will depend on how the configuration file is found.  If the system-wide DNSSEC-Tools file
	   is used, then the name will be dnssec-tools.conf.  If the -config option is used, then the name used with the option will be used.  If
	   a .conf file is found in the realm's hoard, then the full filename will be used.

WARNINGS

       root is not allowed to run buildrealms.	Some of the actions taken by buildrealms can be devastating if a misconfigured (or maliciously
       constructed) realm file is used to control construction.

       buildrealms is not clairvoyant.	It does the best it can, but it is a general tool.  The resulting realms should be checked to ensure they
       are set up as desired.  In particular, you should check the realm file rollrec files, keyrec files, and configuration file.

       No reverse functionality has been implemented, so once run, the files are modified, moved, and copied.  It might not be a bad idea to back
       up your files prior to running buildrealms, just in case...

COMMANDS

       create
	   The create command builds the whole realms environment.  buildrealms takes the following actions when given this command:

       trees
	   The trees command builds the basic directory hierarchy for each realm.  The following directories are created for each realm:

OPTIONS

       -actions
	   Display the file actions taken by buildrealms.  This includes directory creations, file copies, and file moves.  If used in conjunction
	   with the -nobuild option, buildrealms will not perform the actions, but will display the actions that would otherwise have been taken.

       -clear
	   This flag indicates that buildrealms should delete the current staging area and its contents prior to building the realms.

       -config conffile
	   conffile is the DNSSEC-Tools configuration file to copy for each realm.

       -directory target
	   target is the target directory for the realms to be built by buildrealms.  The new realms will not be moved to this directory, but the
	   realms' files will reflect the use of this directory.  If this option is not specified, the current directory will be used.

	   If -directory and -stagedir use the same directory, then the realms environment will be build in the final directory.

       -nobuild
	   This option tells buildrealms to go through the motions of building the new realms, but not to actually build anything.  If this is
	   used in conjunctions with the -actions option, buildrealms will show the actions that would have been taken.

       -stagedir directory
	   This directory in which the new realms hierarchy is built.  The default staging area is ./staging-buildrealms if this option is not
	   specified.

	   If -directory and -stagedir use the same directory, then the realms environment will be build in the final directory.

       -quiet
	   buildrealms is prevented from printing any non-error output.  This option and the -verbose option are mutually exclusive.

       -verbose
	   buildrealms prints a lot of information about what it is doing.  This option and the -quiet option are mutually exclusive.

       -Version
	   Displays the version number.

       -help
	   Displays a help message.

EXAMPLES

       The following examples may help clarify the use of buildrealms.	In each example, the following realms file will be used.

	   realm "example"
	       state	       "active"
	       configdir       "configs/example"
	       statedir        "states/example"
	       realmdir        "r-example"
	       rollrec	       "demo-example.rollrec"
	       administrator   "zonefolks@example.com"
	       display	       "1"
	       manager	       "rollerd"
	       args	       "-loglevel phase -logfile log.example"
	       hoard	       "r-example"

	   realm "test"
	       state	       "active"
	       realmdir        "r-test"
	       configdir       "configs/test"
	       statedir        "states/test"
	       rollrec	       "demo-test.rollrec"
	       manager	       "rollerd"
	       args	       "-loglevel tmi -logfile log.test"
	       display	       "1"
	       hoard	       "r-test"

   CREATE EXAMPLE
       Each realm record contains a hoard field that buildrealms will use to find that realm's files.  After running buildrealms demo.realm create
       with the realms file above, the following directories will be created:

	   staging-buildrealms/
	   staging-buildrealms/configs/
	   staging-buildrealms/configs/example/
	   staging-buildrealms/configs/example/dnssec-tools/
	   staging-buildrealms/configs/test/
	   staging-buildrealms/configs/test/dnssec-tools/

	   staging-buildrealms/r-example/
	   staging-buildrealms/r-example/dnssec-tools/
	   staging-buildrealms/r-test/
	   staging-buildrealms/r-test/dnssec-tools/

	   staging-buildrealms/states/
	   staging-buildrealms/states/example/
	   staging-buildrealms/states/example/key-archive/
	   staging-buildrealms/states/test/
	   staging-buildrealms/states/test/key-archive/

       The following files will be moved into the staging area.  In the interests of brevity this is only a subset of files moved to the staging
       area; most of the key files have not been included:

	   staging-buildrealms/demo.realm

	   staging-buildrealms/configs/example/dnssec-tools/dnssec-tools.conf
	   staging-buildrealms/configs/test/dnssec-tools/dnssec-tools.conf

	   staging-buildrealms/r-example/demo-example.rollrec
	   staging-buildrealms/r-example/demo.com
	   staging-buildrealms/r-example/demo.com.signed
	   staging-buildrealms/r-example/dsset-demo.com.
	   staging-buildrealms/r-example/dsset-example.com.
	   staging-buildrealms/r-example/dsset-test.com.
	   staging-buildrealms/r-example/example.com
	   staging-buildrealms/r-example/example.com.signed
	   staging-buildrealms/r-example/Kdemo.com.+005+16933.key
	   staging-buildrealms/r-example/Kdemo.com.+005+16933.private
	   staging-buildrealms/r-example/test.com
	   staging-buildrealms/r-example/test.com.signed

	   staging-buildrealms/r-test/demo-test.rollrec
	   staging-buildrealms/r-test/dev.com
	   staging-buildrealms/r-test/dev.com.signed
	   staging-buildrealms/r-test/dsset-dev.com.
	   staging-buildrealms/r-test/dsset-test.com.
	   staging-buildrealms/r-test/Ktest.com.+005+34236.key
	   staging-buildrealms/r-test/Ktest.com.+005+34236.private
	   staging-buildrealms/r-test/test.com
	   staging-buildrealms/r-test/test.com.signed

   TREES EXAMPLE
       After running buildrealms demo.realm trees with the realms file above, the following directories will be created:

	   staging-buildrealms/
	   staging-buildrealms/configs/
	   staging-buildrealms/configs/example/
	   staging-buildrealms/configs/example/dnssec-tools/
	   staging-buildrealms/configs/test/
	   staging-buildrealms/configs/test/dnssec-tools/

	   staging-buildrealms/r-example/
	   staging-buildrealms/r-test/

	   staging-buildrealms/states/
	   staging-buildrealms/states/example/
	   staging-buildrealms/states/test/

       No additional files or directories are created by this command.
